The MX-508 features 84dB of gain to ensure full output with low-level or distant microphones. MX-508 is an 8-input stereo rackmountable mixer.
The unit shall be an eight input stereo mixer having separate transformer-isolated balanced outputs for both left and right channels. There shall be an electronically balanced mono summed output with separate front panel level control. Each input channel shall have level and stereo-balance controls on one concentric pot. Two aux sends on each channel must be provided with one internally selected pre-fader /EQ and the other post fader/EQ. The Pre/Post determination of the Aux sends shall be configurable via circuit board jumper connections.
Each input channel shall have three-band equalization control with adjustable mid-band frequency sweep. The equalization shall consist of high and low shelving points being fixed at 130Hz and 7kHz, and the mid-band peaking EQ control must be adjustable between 140Hz and 8kHz. Each input channel shall have 40dB of available gain trim and a switch for mic/line selection on the front panel, as well as a 20dB mic input pad on the rear panel. Each input channel shall have in/out insert points on separate 1/4" phone connections, 1/4" phone connectors for balanced line input sources, and XLR electronically-balanced connectors for microphones. Phantom power of +48VDC on each input must be available via a front panel switch.
There shall be two Master Aux Sends provided and two panable Master Aux Returns (one stereo and one mono). There shall be a front panel 3.5mm stereo line input jack, and an additional back panel stereo line input on RCA jacks, both sharing a single level control to the Mains or Aux 1. Separate stereo RCA line outputs must also be provided. There shall be Pre-Master Sub In/Out patch points for left and right and Aux Sub outputs on 1/4" phone jacks for linking other mixers. A selectable Headphone output with level control to monitor either Left and Right or Aux 1 and 2 must be provided on the front panel. Overall gain available from Mic Input to Master Output shall be 84dB, and the Output level shall be +24dBm into 600 Ohms.
The mixer unit shall be no higher than three rack spaces and must be fully covered under a five year warranty. The mixer must be manufactured in America, with a shipping weight of 19 pounds. The mixer shall be the model MX-508, manufactured by Ashly Audio, Inc. No other unit shall be
acceptable unless data submitted from an independent test laboratory verifies that the above size/performance specifications are met.
