Each stereo line input shall include a rear panel screwdriver adjustable level control, and shall be capable of accepting either -10dB or +4dB signals Stereo line inputs 1-4 shall be provided on female RCA connectors. [. . . ] Four front panel push-buttons, with associated LED indicators, shall allow selection of stereo line input signals. The mic/line input shall have 60dB of gain, and shall include a rear panel screwdriver adjustable 40dB trim control, a 30dB pad switch, a peak indicator, and a front panel rotary level control. The input shall be able to accept low-impedance microphone signals or line-level signals. A rear panel switch shall activate +24 volt phantom power for condenser microphones. The mic/line input shall be provided on a plug-in barrier strip, with additional screw terminals available to program talkover muting of the stereo line signals. Talkover muting may be triggered either by an external switch or by signal present at the mic/line input. Default power-up settings shall be programmable for sources & level. The stereo preamp/mixer shall have a Frequency Response of +0/-0. 5dB from 20Hz to 20kHz at +4dBu. Output Noise shall be less than -85dBu from 20Hz to 20kHz at nominal levels. The stereo preamp/mixer shall be CE marked, UL / C-UL listed, and shall incorporate AES48-2005 Grounding & EMC practices. The stereo preamp/mixer shall be compliant with EU Directive 2002/95/EC, the RoHS directive. The stereo preamp/mixer shall be a BIAMP SPM412e. Biamp Systems, 10074 S. W.
