Connect the video out of the slave subwoofer, go to the settings screen, establish the low pass crossover, slope, phase, polarity, and night mode settings from the master subwoofer, then save settings.

  • Page 18: Subwoofer Setup - Overview

    O N - S C R E E N S e t u p This section describes adjusting the onscreen settings of your Digital Drive subwoofer. You will be performing all the setup functions using the buttons of your Velodyne-supplied remote control and seeing the results on your TV screen.
  • Page 19 Figure 3: Introductory Screen See Figure 3. This the Introductory screen. Notice that as you change settings (such as preset, volume, etc.) they are shown on this screen. You enter setup mode by pressing MENU and entering the code 12345. Upon successful entry of this code, the system takes you to the EQ Setup screen, as shown in Figure 4.
  • Page 20 Figure 4: EQ Setup screen The EQ Setup screen includes a “SYSTEM RESPONSE” “sweep” window and a graphic equalizer. You use these settings to equalize your room. The graphic equalizer features 8 bands, each of which can be used at its current frequency, or can be infinitely adjusted to the frequency and EQ you desire.
  • Page 21 6. EQ Defeat All six presets contain the following fields: • Low Pass Crossover Frequency and Slope – Adjust the upper limit of your subwoofer’s frequency response. Select a crossover setting, in increments of 1, between 15Hz and 199Hz and slope at 6, 12, 18, 24, 30, 36, 42 and 48 dB/octave.
  • Page 22 • Night Mode Maximum Volume – When the NIGHT mode button is pressed on the remote, this setting is invoked. Night mode is indicated by the amber bar underlining the VELODYNE logo. The subwoofer will not play louder than this volume level until the night mode is defeated.

    Input should be configured for stereo. 5. Set the video input where you connected the video output as the active TV image. The introductory screen with the Velodyne logo and “Velodyne Digital Drive” should now appear on your TV screen, as follows: w w w .

  • Page 26 7. Use the DD remote control to MUTE the subwoofer. 8. Raise the volume on your receiver/processor until the DD test sweep (a tone that sweeps from 20Hz up to 200Hz) can be heard from your system’s speakers. Continue to raise the volume until the “SYSTEM RESPONSE”...
  • Page 27 9. Now use the DD remote control to unmute the subwoofer, then use the volume up and down keys to match the level of the subwoofer to your full range speakers. That is, the “SYSTEM RESPONSE” graph should be relatively flat (although at this point there will be peaks and valleys that will be addressed next).
  • Page 28 Avoid these locations when possible. When using a pair of Velodyne subwoofers in stereo, it is preferable to place each subwoofer by the satellite of the same channel. If moving your satellites is an option, they too can contribute to peaks and valleys and should be likewise placed through experimentation.
  • Page 29 Digital Drive gives you maximum flexibility to make the most out of any subwoofer placement position. 11. Now that the room location has been chosen, turn off the subwoofer and the rest of your system, permanently route the wiring, and reconnect to your subwoofer.
  • Page 30 AND REMEMBER: Use the UP , DOWN, RIGHT and LEFT directional arrow buttons that surround SELECT to move through the fields of the setup screen, and change settings by using the SELECT button, then the UP and DOWN arrow keys. Or, you can skip the SELECT button and change values using the SET +/- buttons.
  • Page 31 TIP: To see immediate feedback on the effects of your changes to the “SYSTEM RESPONSE” graph, press the TEST button. The following screen appears: Press TEST again to return to the System Settings screen. w w w . v e l o d y n e . c o m Digital Drive User’s Manual...
  • Page 32 NOTE: Some receivers/processors supply a signal that is already crossed over – i.e. just the bass frequencies. If this is the case, you will want to defeat the subwoofer’s low pass crossover. To defeat the low pass crossover, press the SELECT key, then the RESET key. The following screen appears: w w w .
  • Page 33 You will often see a dip or peak in the crossover frequency between your subwoofer and main speakers. Rather than correcting this dip with an EQ, try adjusting the phase and polarity settings.
  • Page 34 NOTE: The following step shows using the graphic equalizer (using fixed frequencies and Q) to equalize the room. 18. Next, return to the EQ setup screen and adjust the graphical EQs to eliminate peaks and valleys from the room response. Use the right and left arrow keys to position the cursor over the EQ you wish to adjust.
  • Page 35 19. Continue this process until the “SYSTEM RESPONSE” graph shows a +/– 3 dB response across the bass frequencies (that is, up to about 120Hz.). Note that this does not necessarily mean a “ruler flat” response; +/- 3dB is typical for an optimized response curve.
  • Page 36 20. To have the unit EQ itself, select the auto EQ option, as shown: When this mode is selected, the unit automatically resets all EQs to their original frequencies, and Q settings (but retains any level changes you may have made). The AUTO EQ proceeds until you either save settings, press SELECT to return to manual EQ, move the cursor off the AUTO EQ field (in which case the field automatically reverts to MANUAL), or twenty-five sweeps have occurred.
  • Page 37 NOTE: The following steps use the parametric equalizer to achieve room equalization. If you do not wish to use the parametric EQ feature, skip to step 24. 21. To use the parametric EQ feature, position the cursor over the EQ and press the SELECT button.
  • Page 38 22. To manipulate a parametric EQ, you can now use the LEFT and RIGHT arrow keys to move the frequency up and down, and the SET + and SET – keys to change the Q value. Use the UP and DOWN arrow keys to adjust the level of the EQ as before. A selected EQ that has been moved, with its level raised and Q adjusted is shown below: 23.
  • Page 39 24. Once the room has been equalized, you may want to return to the Settings Setup screen (by positioning the cursor over the NEXT field on the EQ setup screen and pressing SELECT) and review/modify the presets. This step is required ONLY if you wish to customize the presets.
  • Page 40 So, if you found during setup that 30 was a good setup volume for the subwoofer, then if you increased the volume for preset one to 40, the 40 volume would be invoked when preset one were selected for listening. If the system volume is changed (using the VOL + or VOL –...
  • Page 41 You will note that presets 1-4 are shipped from the factory with predetermined settings, preset 5’s contour is set at 0 level from the factory and customizable by the user (i.e. flat), and preset 6 defeats all the EQs to demonstrate the effect the equalization of the subwoofer has on room response.
  • Page 42 24. As a final thought on matching your Digital Drive subwoofer to your room, don’t forget the “objective listening” test. That is, make sure the unit sounds good to you! Often, you may want to add a bit more bass than what would normally be considered “flat” even after you remove the major peaks and valleys to achieve a flat frequency response.

  • Page 43: Restoring Defaults

    When the unit saves settings, you will see the video flicker and you may hear a slight tick in your main speakers. This is normal behavior. NOTE: The Digital Drive subwoofer stores all of its settings in internal “Flash” memory. This memory persists even if the woofer is turned off, loses power, or undergoes a programming update, so you need not worry about losing your customized settings.
  • Page 44 These settings are shown on the introductory screen, as follows: NOTE: If you change the volume on your DD subwoofer but later wish to return to the volume you established during setup (that is, as of your last save), press the RESET button.

    While the goal is perfectly flat response, this may not be possible in the higher frequencies of the subwoofer’s response due to peaks or valleys introduced by the satellites.
