Configuring the Unit for Transport

You can easily carry your sound system using the XP510i's "Slide and Lock" feature. The "Slide and Lock" speaker enclosures allow you to connect both speakers together into a single, easy to carry unit. Follow these steps to configure the XP510i for easy transport.

1. Place one speaker on the floor and set it on its side.
   
2. Position the second speaker above the first speaker and line up the "Slide and Lock" tracks and grooves so that they are parallel to the speaker on the floor.
   
   Speaker cabinets must be reversed with respect to top and bottom.
3. Slide the second speaker into the speaker on the floor making certain that the two speakers stay parallel to each other. in place.
   
4. You will feel a slight click when the two speakers are in place.

Device Mixer Layout

1. Channel Input Jacks (channels 1 - 4)
   MIC – XLR connector – Use these XLR jacks to connect low impedance microphones to the XP510i's built-in mic preamps.
   LINE - 1/4-inch phone connector – Use these 1/4" jacks to connect instrument or audio sources with line-level signals to the XP510i. You can connect the outputs from acoustic guitar pickups, keyboards, drum machines, CD/MP3/TAPE players and other units with line level outputs here.
2. Stereo Channel Input Jacks (channels 5/6, 7/8, 9/10)
   For stereo inputs, use the LINE L to connect the left channel and the LINE R to connect the right channel. Use these inputs to connect high impedance microphones, synthesizers, drum machines, MP3, CD, tape players or any other line level device. The XP510i features both 1/4" phone and RCA connectors.
3. MIC/LINE switch (channels 1 - 4)
   The MIC position changes the gain of both input jacks to MIC level. The LINE position reduces the gain of both jacks by 30dB to line level.
4. LIMIT/COMP switch
   Set the LIMIT/COMP switch to the COMP position to apply compression or set it to the LIMIT position to apply limiting.
5. Equalizer control knobs
   HIGH FREQUENCY (HF) – The HF knob controls the amount of Treble applied to each channel. The channel's HIGH frequency response is flat when the knob is in the "12:00" position. Rotating the knob to the right will boost the channel's high frequency response above 10 kHz by 15 dB, and rotating it towards the left will cut the high frequency response by 15 dB.
   LOW FREQUENCY (LF) – The LF knob controls the amount of Bass applied to each channel. The channel's LOW frequency response is flat when the knob is in the "12:00" position. Rotating the knob to the right will boost the channel's low frequency response below 100 Hz by 15 dB, and rotating it towards the left will cut the low frequency response by 15 dB.
6. REVERB switch
   Use the REVERB switch to add an effect to a Mic or Line input on any of the inputs 1 – 4. The REVERB LED indicator lights GREEN when the REVERB is ON.
7. VOLUME control knob
   This knob sets the overall level for the Mic or Line input.
   NOTE: To reduce noise, set the VOLUME controls on any unused channels to the minimum setting.
8. MONITOR OUT jacks
   The signal present at the MONITOR OUT jacks is sent from the MONITOR level control knob, which is fed from the input channels. The MASTER control does not affect the MONITOR OUT signal.
9. REC OUT jacks
   This output is used to send the main mix to an external recorder. The signal present at this connector is the L/R bus signal before it has passed through the MASTER level control. The nominal output level is -10 dBV and the impedance is 100 Ohms.
10. SPEAKER OUT jacks
    The XP510i has two 1/4-inch phone connectors, which are powered outputs used to connect your left and right speaker. Use the included speaker cables to connect the speakers.
    
    The total impedance load for each side of the amplifier must not be less than 8 Ohms. Do not connect additional speakers to the XP510i mixer.
11. AC – IEC inlet
    Connect the supplied heavy-gauge 3-pin "IEC" power cable here.
12. POWER switch
    Use the POWER switch to turn power to the XP510i on or off.
13. iPOD DOCK
    The XP510i has a built-in iPod dock which can be used to connect most of the latest iPod models. The iPod signal is controlled by the Channel 9/10 VOLUME control.
14. SPEECH/MUSIC switch
    The SPEECH/MUSIC switch is used to change the overall frequency response, or tone contour, for the XP510i sound system. If your application is mainly for MUSIC, press the switch down to select the MUSIC response curve. If your application is mainly for SPEECH, leave the switch up to select the SPEECH response curve.
15. MONITOR control knob
    The MONITOR volume control is used to control the overall level sent to the MONITOR OUT, which can be used to send to a second set of powered speakers for monitors.
16. REVERB PROGRAM selector
    This control knob is used to select one of ten, 24-bit DSP effects programs.
17. REVERB control knob
    The REVERB control knob is used to adjust the total amount of reverb added to any channel that has its REVERB switch (see #6) pressed down.
18. MASTER control knob
    The MASTER volume knob controls the overall output level. This knob determines the final output signal level. Signals from all ten channels are routed here just before being routed to the built-in power amplifiers and Left and Right speaker output jacks (see #10).
19. METER LED indicators
    This six-segment bar meter shows the XP510i's output level. For optimum signal-to-noise ratio, set the VOLUME control so that program material is usually at or around +3 to +6 VU, with occasional, but not steady excursions to the red "LIMIT" segment.
20. PHANTOM switch
    The XP510i features an onboard, Phantom power supply to operate condenser microphones. When the switch is engaged, the LED will illuminate indicating that phantom power is now available on the microphone pre-amps.
    
    To avoid a loud pop, be sure to turn down the MASTER level control before plugging and unplugging the mic cables when the phantom power is active.
21. POWER LED indicator
    The Power LED will illuminate when the MAIN power switch is turned on.

Applying Reverb

The XP510i features built-in, high quality, 24-bit Reverb Effects that you can add to channels 1 through 4. You can use the reverb to create a studio effect by simply following the steps below:

1. Connect a mic or instrument to the desired channel, and adjust the volume and equalizer to your liking.
2. Use the Reverb Program selector to choose one of the ten built-in digital effects.
   
3. Press the REVERB switch down on the channel to which you want to add the reverb effect.
   
4. Once you have selected the channel(s) for effects by using the channel REVERB switch, raise the REVERB main level control to apply the amount of reverb desired.
