User manual BIAMP 301 & 601

[. . . ] For best performance, adjust Trim so the Peak Indicator flashes only on occasional peaks in signal level (see Pad on next page). Channel Level: These controls adjust the level of channel signal sent to the Main Out section. Level control settings will vary from channel to channel, depending upon the desired mix. [. . . ] Main Out signal is a mix of the input channel signals, plus signal from Stack In, as well as any processing which may be inserted at Patch (see Stack In & Patch below). Stack In: These three terminals provide a line level input for signals from external devices, such as other mixers. Stack Input signal is combined with the channel signals, before being sent to the Main Out section. Connect balanced inputs with high to (+), low to (-), and ground to ( ). For unbalanced use, connect inputs with high to (+) and ground to both (-) & ( ). Patch: These three terminals provide an insert point for connection of external processing equipment at the Main Out section. The (in) terminal provides a return from the external device Ground for both connections is supplied by the ( ) terminal. Patch may also be used as an unbalanced, pre-Master Level output, with the (out) terminal as the send and the ( ) terminal as ground. Depress the Patch Enable switch only when Patch is used as an insert, and release the Patch Enable switch when Patch is used as an output (see Enable Switches below). Remote: These three terminals allow remote control of the Main Out level. Controls may be wired up to 2000 feet from the mixer, using 2-conductor shielded cable (see Remote Control on page 4). Switches may be used alone (on/off) or with variable resistors (adjustable mute). Depress the Remote Enable switch only when using remote controls (see Enable Switches below). Enable Switches: These switches activate the normal functions of the Patch & Remote terminals (see above). Patch terminals may still be used as an unbalanced output even when disabled. If Remote is enabled, but no control is connected, signal will be muted (off) at the Main Out. Ch 3 / Ch 6 Duck switches: These DIP switches assign which input signals (Channels 1 & 2 on 301; Channels 1~5 on 601) will automatically trigger ducking (-15dB attenuation) on the last channel (Channel 3 on 301; Channel 6 on 601) for talk-over applications. Phntm Switches: These switches assign +24V Phantom Power to the Inputs (for condenser mics).
