User manual BIAMP MODEL 1642 MIXING CONSOLE

[. . . ] 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. Optimum Master settings are near the 12 o'clock position (unity gain) or below. Threshold: A limiter is provided at Main Output to help eliminate unwanted peaks in signal level. [. . . ] It is connected to the DC Power Jack on the rear side of the mixer. To ensure compatibility, only use a Biamp Systems supplied power supply. Main Output: This plug-in barrier strip provides the balanced linelevel Main Output from the mixer. For balanced connection, wire high (+), low (-), and ground ( ). For unbalanced connection, wire high (+) and ground ( ), leaving (-) unconnected. Signal level will be reduced by 6dB when output is unbalanced. Main Output level is affected by the front panel Master control, as well as by remote control (see Remote below). Stack In: This plug-in barrier strip provides the balanced line-level Stack In to the mixer. Signal entering here is combined with signals from the input channels, and is then sent to the Main Output section. When using multiple 801i mixers within a system, connect Main Output of one mixer to Stack In of the next mixer, and so forth. All mixers except the final 801i should be assigned as `slaves' (see Master DIP Switches below). 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 Remote Control Remote: The output level of an 801i 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 below). Potentiometers are wired high (V), wiper (C), and low ( ). Ramp voltage is wired positive (C) and ground( ). The Remote port of the 801i 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 801i mixer, it only attenuates from the maximum level settings established at the mixer.
