User manual BIAMP 801

[. . . ] Optimum Level settings are near the 12 o'clock position (unity gain). Bass: This control provides low-frequency tonal adjustment (±10dB @ 100Hz) for signals at Main Patch & Main Output. Treble: This control provides high-frequency tonal adjustment (±10dB @ 10kHz) for signals at Main Patch & Main Output. -20 Indicator: This red LED will light whenever signal levels reach -20dB (signal present) at Main Output. Master: This control adjusts the level of overall signal sent to Main Output. [. . . ] Phantom power (+24VDC) is available (see DIP Switches below), with +48V phantom power as an option (model 48VPS) (see Options on pg. The Aux input accepts either balanced mono line input or unbalanced stereo line input (see DIP switches below). Aux input cannot accept mic input signal, or the optional input isolation transformer, and does not provide phantom power. Master DIP Switches: These switches assign functions to the mixer as a whole (when pushed up). Override allows automatic muting of all other inputs when signal is present in Channel 1. Remote allows remote control of Main Output level, by enabling the Remote terminals (see above). DIP Switches (Channels 1~8 & Aux): These switches assign functions to the individual inputs (when pushed up). Phantom (Channels 1~8 only) turns on phantom power (for condenser mics). Duck Aux (Channels 1~8 only) allows channel signal presence to activate -15dB attenuation at Aux input (ducking). HP Filter enables a high-pass filter on the input (6dB/octave @ 170Hz). Sum (Aux only) converts Aux from standard balanced input to stereo (L/R) summing input. 3 OPTIONS Override: Channel 1 Override can be manually triggered by an external switch wired across pins 3 & 6 of the DC Out jack (see diagram on next page). Channel 1 Override can also be triggered automatically by signal present in Channel 1 (see Master DIP Switches on pg. When additional 801 mixers are being used (for more inputs), pins 3 & 6 of the various DC Out jacks can be wired together (in parallel). This allows Channel 1 Override triggering (manual or automatic) to be transmitted to all 801 mixers in the system. The additional 801 mixers should be assigned as `slaves' (see Master DIP Switches on pg. 3), which allows all channels (except Channel 1 of the `master' 801 mixer) to be muted. If necessary, specific channels of the system may then be excluded from Channel 1 Override muting, by assigning them as `priority' channels (see DIP switches on pg. Remote: The output level of an 801 mixer can be remotely controlled via an external potentiometer (5k~50k ohm linear taper) or ramp control voltage (0~+10VDC). An RP-L1 remote control panel is available as an option (see diagram on next page). The Remote port of the 801 mixer must be enabled before remote control of output level is possible (see Master DIP Switches on pg. Remote control does not change physical settings on the 801 mixer, it only attenuates from the maximum level settings established at the mixer. 48 Volt Phantom Power: The 801 mixer provides +24 Volts DC phantom power for condenser microphones (see DIP Switches on pg.
