The mic/line pre-amplifiers shall be of discrete transistor design to insure low noise and low distortion performance. Phantom Power shall be +24 Volts, selectable on each mic/line input via rear panel DIP switches. The auxiliary line input shall be selectable for either balanced mono input or unbalanced stereo summing input, via rear panel DIP switch. Rear panel DIP switches shall allow signal present in any or all of the eight mic/line inputs to trigger 15dB of automatic attenuation at the auxiliary line input. Front panel screw-driver adjustable trim controls and rear panel pad switches shall be provided on each input channel. The mixer shall be CE marked with a UL / C-UL listed power source, and shall incorporate AES48-2005 Grounding & EMC practices. The mixer shall be compliant with EU Directive 2002/95/EC, the RoHS directive. The mixer shall be a BIAMP 801i. Biamp Systems, 10074 S. W. Arctic Drive, Beaverton, Oregon 97005 U. S. A.
