PREPARE FOR INSTALLATION

your new Velodyne subwoofer provides for a number of installation options. Read all of the installation information below in order to deter mine which installation option is best for your system. Remember to perform all installation procedures with system power turned off to prevent possible damage.

Placement

The first step in installing your new EQ-Max sub is to determine where it will be placed in the room. Unpack the system carefully and use the following guidelines in order to find the best room placement option.

True subwoofers operate at extremely low frequencies which are primarily omni-directional. Keep in mind that frequency response and output level can be drastically influenced by placement, depending on the acoustic properties of the listening room. To obtain optimum output from your subwoofer, try placing it within a foot of a corner. This location will offer the greatest output levels and optimum low frequency extension. If at all possible, your subwoofer should be placed along a wall. The worst location for a subwoofer is typically far away from any walls and close to the center of your room, or close to a doorway or opening into another room. Avoid these locations when possible. When using a pair of Velodyne subwoofers in stereo, it is preferable to feed each subwoofer with one channel and place each subwoofer near the satellite of the same channel.

Depending on the size and type of furnishings in the room, perfect placement may not be possible. Finding the best location within your environment will likely require some experimentation. We suggest you experiment with the location during setup to find what sounds best to you when seated in your typical listening position.

For more information on placement, please refer to Velodyne's Subwoofer Placement Recommendations Guide.

Regardless of where you install your Velodyne subwoofer, it must remain in an upright position (woofer facing forward). Using, shipping or storing the subwoofer in any other position for an extended period of time may result in damage to the unit not covered by warranty.

This subwoofer has electronics built into the cabinet. Do not place the cabinet next to sources of heat such as furnace registers, radiators, etc. Do not place the unit near sources of excessive moisture such as evaporative coolers, humidifiers, etc. The power cord should be routed in such a way that it will not be walked on, pinched or compressed in any way that could result in damage to the insulation or wire.

Your Velodyne EQ-Max subwoofer is NOT magnetically shielded. Should you find it necessary to use it with an older CRT monitor or TV, keep it at least two feet from the monitor. experiment for correct distance by minimizing distortion of the picture and colors.

Inputs

Your new subwoofer is equipped with speaker-level and line-level inputs. Use the LINE-LEVEL jacks when connecting your subwoofer to a pre-amp, signal processor (such as LFE out or sub out), line-level crossover, or receiver with pre-amp level outputs. When using the line level jacks, some receivers may not provide enough signal to have the unit's auto-on feature operate properly. Additionally, this lack of signal may also cause the subwoofer to produce less output than it is capable of.

To alleviate this condition, we recommend the following steps:

1. If using line level jacks, BOTH THE LEFT AND RIGHT INPUT SHOULD ALWAYS BE USED – never use just the left or just the right input. If using line level connections from a preamp or signal processor, use both left and Right inputs from your preprocessor or preamp and connect them to the Left and Right inputs on your subwoofer. (See figure 4)
   
   Figure 4. Line-Level Subwoofer Connection Diagram.
2. If using a receiver with LFE out, be sure the LFE channel is sending adequate signal to the subwoofer. The subwoofer's default volume setting is 30 on a 1-80 scale (roughly 1/3 volume). Adjust the LFE channel on your receiver or processor to achieve the desired bass output. See your receiver or processor's owner's manual for more information. (See figure 5)
   
   Figure 5. Speaker-Level Subwoofer Connection Diagram.

Volume Control

This control allows you to balance the output from the subwoofer to the main speakers in your system. This control should be set to achieve similar output levels from both the main speakers and subwoofer when listening to music. The default volume setting is 30 on a 1-80 scale.

Some manufacturers preset their receivers with the Sub-out channel signal at a minimum level. It is very important to verify that your receiver Sub-out channel is set to the same output level as your front right and left channels. Refer to your receiver manual for the individual channel level adjustment procedure. If your receiver Sub-out channel is set too low, the subwoofer may appear to have a weak output, it may sound noisy or distorted, and the Auto on/off feature may not operate properly.

Low-pass Crossover

Low-pass Crossover - 40 to 135 Hz
All inputs sum the left and right channels together, with the resulting signal passing through an adjustable low-pass crossover before being amplified. The crossover control allows you to adjust the upper limit of the subwoofer's frequency response from 40 to 135 Hz. The subwoofer's response will begin rolling off above the frequency you set this control to. you should set the crossover frequency to obtain a smooth and seamless transition from the subwoofer to the main speakers in your system. If your main speakers are smaller with limited low frequency output, you may wish to choose a higher frequency (such as 100 - 120 Hz) than you would with larger speakers which have greater low frequency output. The default crossover setting is 80 Hz. With larger speakers, you may want to set this even lower, for example 70 Hz.

Phase Adjustment

Phase Adjustment - 0°/90°/180°/270°
This control allows you to change the phase of the subwoofer's output signal to correct for any possible mismatch and resulting cancellation between the subwoofer and your main speakers/amplifier. To adjust, simply listen to the system with music playing, then depress the various phase switches on the remote control and listen for a change in mid-bass frequency output. The correct position will have a greater amount of overall bass energy at all frequencies. If the settings sound similar, we recommend the "0" position. See the remote control section for more information.

Auto Turn on Function

The subwoofer will turn itself on automatically when an audio signal is present. If no signal is present for approximately eight minutes, the unit will switch to standby mode (blank LED). While in standby mode, your subwoofer will draw very minimal power. your sub is shipped in the "Always on" position. In order to activate the circuit, change the switch to "Stand-by".

If the Sub-out channel signal level from your receiver is too weak, this feature will not operate properly and shut the subwoofer off while you are listening to it. To correct this, see the VOLUME CONTROL section above.

DETAILED EXPLANATION OF THE REAR PANEL CONNECTION

Figure 2. EQ-Max8, EQ-Max10 and EQ-Max12 Rear Panel Connections.

Figure 3. EQ-MAX15 Rear Panel Connections.

Following are brief descriptions of the controls and connections described in Figures 3, 4 and 5. More detail of these connections can be found below:

1. SPEAKER LEVEL INPUT Terminals
   Connect these input terminals to the speaker output terminals of your amplifier or receiver. If you use this method of connection, when you go to the receiver speaker set up menu, make sure you select the large speaker option.
2. SPEAKER LEVEL OUTPUT Terminals
   Sends a crossed-over speaker-level signal to the front speakers. See below for a more detailed explanation of this crossover.
3. IR INPUT
   This is a connection that allows the utilization of a third party infrared remote sensor, such as Elan or Xantech, or an extended cable for placement closer to your other remote controlled equipment. This keeps you from awkward control angles using the infrared remote control.
4. LINE OUTPUT
   Connect these jacks to the LINE IN preamp input to use the EQ-Max's internal high-pass crossover. The signal fed from these connectors is rolled off below 120 Hz.
   LINE INPUT/LFE
   Connect these jacks to the LINE OUT preamp output, LFE output, or subwoofer output jacks of your receiver/processor. If using the LFE output from your receiver or processor, plug the single cable into the "L" – LFE input or, for more signal, use a "Y" connector (not included) and feed the signal into both "R" and "L" inputs.
5. AUTO ON/OFF Switch
   Use this switch to select between "stand-by" mode (woofer shuts off after eight minutes) and "always on" operation.
6. VOLUME Control
   This control allows you to balance the output from the subwoofer to the main speakers in your system. This control should be set to achieve similar volume level from between both the main speakers and subwoofer. When pressing volume up or down, set the level while watching the LED display for reference.

Note: Volume is also controllable by using the supplied remote. When defaults are restored, the default is 30 out of 80.

7. LOW-PASS CROSSOVER
   Use this knob to select the frequency above which you wish to cut off the signal to the subwoofer. When the knob is turned all the way to the left, the Subwoofer Direct feature is invoked and the subwoofer plays all frequencies up to 135 Hz.

Your new subwoofer is equipped with both speaker-level and line-level inputs. Use the RCA/Phono type "INPUT" jacks when connecting your subwoofer to a pre-amp, signal processor, or line-level crossover. The "SPEAKER LEVEL INPUT" jacks connect directly to the speaker outputs of an integrated amplifier or receiver. Your amplifier section will notice no additional loading effects when you use these inputs because of their high impedance.

Note: Do not use both the RCA/Phono "INPUT" connections and "SPEAKER LEVEL INPUT" connections simultaneously.

Low-Pass Crossover

Both sets of inputs sum the left and right channels together and the resulting signal is passed through an adjustable low-pass crossover before being amplified. The crossover control allows you to adjust the upper limit of the subwoofer's frequency response from 40 to 135 Hz. The subwoofer's response will begin rolling off above the frequency you set this control to.

You should set the crossover frequency to obtain a smooth and seamless transition from the subwoofer to the main speakers in your system. If your main speakers are smaller units with limited low frequency output, you may wish to choose a higher frequency (such as 100-120 Hz) than you would with larger speakers which have greater low frequency output. With larger speakers, you might start with this control set lower, such as 70 Hz.

Subwoofer Direct

Subwoofer Direct is a setting on the low-pass crossover knob and will allow frequencies up to 135 Hz into the subwoofer. See below for a more detailed explanation of this feature.

RECEIVER/PROCESSOR DEVICE OUTPUTS

Your Velodyne Subwoofer is designed to operate using the full range audio signal for input when using our built-in crossover. Many home theater processors/receivers (Dolby Digital, DTS, THX) have a "subwoofer out" jack (sometimes labeled "LFE") that is internally filtered, settable at the receiver/processor, and designed to be used with a powered subwoofer. In some installations, it may be beneficial to use BOTH the Velodyne crossover and the receiver/processor crossover, resulting in a steeper ultimate crossover slope. In some rare cases, combining both an external crossover and the one internal to the subwoofer may result in low output and increased noise. In these installations you may need to bypass the crossover in either the processor or your EQ-Max subwoofer, or simply setting one crossover to a higher frequency (such as 120 Hz) will restore maximum performance.

(Refer to Figure 4 Line-Level Subwoofer Connection Diagram and Figure 5 Speaker-Level Subwoofer Connection Diagram for connection diagrams.)

Note: Connecting main speakers to the rear panel of the sub is optional.

INTERCONNECT CABLES

When installing your new Velodyne subwoofer using the line-level connections, you should always use shielded phono cables. There are many high quality cables available today. It is recommended that you keep the length of cable as short as possible to avoid any potential noise problems.

When using speaker-level connections, use a high quality speaker cable that mates well with the connectors. Be very careful to avoid any loose strands or frayed wires that may result in a short, which may damage your equipment. Cables of extremely large size are not required due to the low current draw of this type of connection. Extremely large gauge wire may not properly fit in the terminals, resulting in a poor connection and possible short circuits.

USAGE

This section addresses usage of your EQ-Max subwoofer.

REMOTE CONTROL
The features of the EQ-Max remote control are listed below.

Figure 6. EQ-Max remote.

• POWER — This button switches your EQ-Max subwoofer unit into standby mode. The woofer will not play and the LED will turn off. The unit will remain in this mode until the POWER button is pressed again. To fully deactivate (i.e. power down) the unit, turn off the power switch on the back panel.
• MUTE — The button mutes the subwoofer's output. The LED on the sub will show 00 if the unit is muted. To unmute the subwoofer, press the MUTE button again and the original volume setting shows on the LED.
• EQ — This button automatically equalizes the subwoofer's output so that it sounds best for its position in the room. To use this feature, remove the grille and plug the supplied microphone into the Mic-In jack on the front baffle of the sub and place the mic in your preferred listening position. Then press EQ on the remote for about 2-3 seconds. The subwoofer emits approximately 12 "sweep tones" that span the frequencies between 20 and 150 Hz. The LED displays "AU" during the Auto-EQ process. After the sweeps are complete, the unit saves its EQ settings and returns to normal operation. To prevent accidental invocation of the eq feature, you must hold down the EQ button for 2-3 seconds before the eq sweeps begin. If the mic is not plugged in, the subwoofer sweeps twice then reverts back to normal functioning without changing any EQ settings.
• PHASE — These buttons allow you to optimize the subwoofer's bass performance relative to the speakers and your listening position. Play some music that has a repetitive heavy bass line. you can use the repeat feature on your CD/DVD player to make this procedure easier. While listening, push one of the four phase buttons, listen for a few moments, and then press the next phase button. In most installations, one of the four button positions will offer an audibly better blend of subwoofer and speakers. The LED will show the phase selected by showing "PH" followed by the phase number: 0, 90, 180 or 270.
• LIGHT — If you wish, you can deactivate the numeric LED on your EQ-Max subwoofer by pressing the LIGHT button on your remote. To reactivate the LED, press the LIGHT button again. When the display has been deactivated, it will light only when you make adjustments to the subwoofer controls and then turn off again.
• NIGHT — Night mode limits the maximum dynamic output of the subwoofer for late night listening or to be more considerate of close neighbors. Press the night button to turn the night mode feature on or off. Activation of night mode causes "n" to appear briefly on the display. When night mode is deactivated, the display shows "n off" and then returns to normal function.
• Volume Control — This control allows you to balance the output from the subwoofer to the main speakers in your system. This control should be set to achieve similar volume level of both the main speakers and subwoofer. When pressing volume up or down, the volume level is shown on the numeric LED on the front panel.

Some manufacturers preset their receivers with the Sub-Out channel signal at a minimum level. It is very important to verify that your receiver Sub-Out channel is set to the same output level as your front right and left channels. Refer to your receiver manual for the individual channel level adjustment procedure. If your receiver Sub-Out channel is set too low, the subwoofer may appear to have a weak output, it may sound noisy or distorted, and the Auto On/Off feature may not operate properly.

Note: The volume can also be adjusted via the buttons on the back panel of the subwoofer. These buttons have the same effect as pressing the up and down volume buttons on your remote. The unit comes preset from the factory with the volume set at 30 out of 80.

• PRESETS — There are four listening presets, consisting of Movies, R&B – Rock, Jazz – Classical, and Games. The presets provide the following characteristics for bass reproduction:

Movies:	Maximum output and impact for explosions and other action adventure movie content.
R&B – Rock:	Provides the driving bass found in today's rock music.
Jazz - Classical:	The tightest, cleanest, lowest distortion bass. The flattest frequency response of the four presets.
Games:	Maximum loudness available for the impact of video games.

The following table indicates musical style and which preset is recommended for it.

Protect the Product from Damage

DO NOT PUT HEAVY OBJECTS ON TOP of the subwoofer cabinet that could scratch or dent the cabinet or case.

DO NOT ALLOW OBJECTS TO FALL INTO OR LIQUIDS TO SPILL ON THE SUBWOOFER ENCLOSURE.

DO NOT EXPOSE SUBWOOFER TO DRIPPING OR SPLASHING FROM LIQUIDS.

DO NOT PLACE LIQUID-FILLED OBJECTS ON OR NEAR THE SUBWOOFER. Examples of liquid-filled objects include flower vases, beverages and liquid-fueled lamps.

DO NOT PUSH OBJECTS OF ANY KIND into the subwoofer.

DO NOT PLACE BURNING CANDLES, INCENSE, OR SMOKING PRODUCTS ON TOP OF OR NEAR THE SUBWOOFER.

DO NOT PLACE A LAPTOP COMPUTER ON TOP OF THE SUBWOOFER. Damage could occur to either the laptop hardware or the subwoofer finish.

Clean

USE A CLEAN, SOFT DAMP CLOTH to remove dust or fingerprints from the subwoofer cabinet. Unplug the subwoofer power cord from the power outlet before cleaning to prevent static electricity from damaging the subwoofer during cleaning.

DO NOT CLEAN THE SUBWOOFER CABINET with detergents, soaps, abrasives, aerosol sprays, chemical solvents, alcohol, or other cleaning solutions.

Service

DO NOT ATTEMPT TO SERVICE THE SUBWOOFER beyond what is described in this owner's manual.

ONLY USE QUALIFIED SERVICE TECHNICIANS TO REPAIR DAMAGED PARTS. Service the subwoofer or transmitter using qualified service technicians when:

• A power cord or plug is damaged
• The power socket on the subwoofer is damaged
• Objects have fallen into the subwoofer or liquid has spilled into the subwoofer
• The subwoofer was rained on or has become partially or fully submerged in water
• The subwoofer does not operate normally or exhibits a marked change in performance
• The cabinet has been dropped or is damaged
• The subwoofer driver's cone and/or suspension is physically damaged

Packaging

Save the carton and packing materials for future use. Using other packaging for this unit may result in severe damage when shipping or moving. you can use this packaging should you ever move or need to return the subwoofer to Velodyne for service. To save storage space, you can flatten the box and put the other packing material in a plastic bag.

Protection Circuitry

The subwoofer is equipped with protection circuitry to provide maximum performance with greatest reliability. The subwoofer is protected against:

• Overdriving the speaker
• Overdriving the amplifier
• Overheating the amplifier
• Excessive drop in power line voltage

The overdrive protection circuitry operates constantly without being audible under most situations.

If the subwoofer should shut down, reduce the volume setting and shut the subwoofer off until it cools down. The time the subwoofer takes to cool down depends on the ambient room temperature, but typically at least 10 minutes are required for the subwoofer to cool down and recover from the thermal shutdown.

Also, plug the unit into a different wall socket. overloaded sockets or damaged home wiring circuits can cause power voltage drops while the subwoofer is drawing high power levels. This condition can result in the subwoofer shutting down intermittently.

Listen Responsibly

REFRAIN FROM LISTENING TO MUSIC AT HIGH VOLUMES for long periods of time to protect you from permanent hearing damage. The United States occupational Health and Safety Administration (OSHA) standards recommend not listening to sound levels of 85 db for more than 8 hours and to wear hearing protection if sound levels exceed 85 db. Refer to the OSHA website for more information and updated recommendations about sound levels and hearing damage: www.osha.gov/dts/osta/otm/noise/standards_more.html

Troubleshoot

Before seeking service for your amplifier or subwoofer, please re-check all systems. Following is a simple troubleshooting guide to assist you.

1. Verify that the unit is plugged in and power outlet used is active.
2. Is the power switch on?
3. Is the unit receiving an input signal from your source?
4. Have all controls (volume, crossover, phase, etc.) been properly set?
5. If the unit has been running at high levels, one of the protection circuits may be engaged. Has the amplifier overheated?
6. Has the power button been depressed on the remote?
7. Make sure binding posts are tightened.
8. Is the remote non-responsive? We recommend replacing the batteries in the remote.

If the protection circuitry is active, the unit may cycle on and off until operating parameters return to normal. Under more serious conditions, the unit may shut off completely. Normal operation should return upon cooling, but you may be required to turn the power off and then on again to reset the unit.

IF THE BASS DOESNT SOUND LOUD ENOUGH TO YOU

1. Increase the subwoofer's VOLUME level.
2. Increase the receiver's LFE or SUB OUT volume level, if it is adjustable.
3. Put the subwoofer closer to a corner of your room.

IF THE UNIT OUTPUT IS DISTORTED, INTERMITTENT OR STOPS

The subwoofer may have shut down due to the protection circuitry.

1. Reduce the volume setting; or
2. Shut the subwoofer off until normal operating conditions return.
