User manual PEAVEY DATABASS

[. . . ] The following cautions should be carefully observed when installing, wiring or using this product: DO NOT use any other power supply or cable other than the one provided with this unit. DO NOT remove the top cover of the DATABASS. There are no user serviceable parts inside. DO NOT use solvents or other cleaners to clean the unit. [. . . ] The Low Cut Switch enables a filter with a corner frequency of 100 Hz and is helpful to filter out rumble, wind noise, breath thumps, and other low-frequency signals that rob amplifier power and muddy the mix. Enabling this switch will affect Channels 1-6 only. The factory default setting for the Low Cut switch is "Defeat" or "Flat". The Mode switch selects either Stereo mode or Mono mode for Channel 7 or 8. In the Stereo mode, the Left input signal feeds the Left mix bus and the Right input signal feeds the Right mix bus via the front panel Level control. In the Mono mode, the summed Left and Right input signals feed both Left and Right mix buses. This allows for a mono source to be used to feed the stereo mix buses. Additionally, it allows for Left and Right outputs of the source to be summed without a Y-cable. In either mode, a summed mono signal feeds the Aux mix bus. The factory default is "Stereo". The EQ switch places the 4-band stereo equalizer in or out of the Left and Right signal paths. In this example, we shall see how multiple DATABASS's can be used effectively for meeting room applications.

In addition, there is a wall mounted control panel in each room with a music ON/OFF switch and Master Volume control. These are wired to the remote control ports on the DATABASS's Remote Connector. - A Room Combine panel allows linking of adjacent rooms, or all three rooms. These are simple switches wired between the DATABASS's Bus Link ports. In this example, we are linking the main audio and the mute bus. - The "house" BGM audio is fed to all three rooms. The music ON/OFF control is actually the Channel 7/8 Remote Select, but since there is no music on Channel 7, the switch acts as an OFF control. - The emergency page audio is wired to each mixer's Channel 1 input.
