Ashly's MX-406, four-decade history in the pro audio industry began with custom designed and manufactured mixing consoles.
The unit shall be a six input stereo mixer having separate balanced outputs for both left and right channels. There shall be a transformer balanced mono-summed output with separate front panel level control. Each input channel shall have level and stereo-balance controls on one concentric pot. An Aux send shall be on each channel factory wired pre-fader/EQ. The Aux send shall be configurable for Pre/Post fader/EQ via circuit board jumper connection. Each input channel shall have a two-band equalization control on one concentric pot located on the front panel.
The equalization shall consist of high and low shelving points being fixed at 70Hz and 8kHz with a cut/boost range of +/- 12dB. Each input channel shall have 40dB of available attenuation on the front panel, as well as a 20dB mic input pad on the rear panel. Each input channel shall have an in/out insert point on a single TRS 1/4" phone connection, and separate 1/4" TRS and XLR connectors for line input and balanced microphone sources. Phantom power of +48VDC for each input must be available via a single rear panel switch. There shall be one Master Aux Output control provided on the front panel. A 1/4" TRS Aux Master Output Jack shall be located on the rear panel.
There shall be an additional Stereo Line Input on back panel RCA jacks and a front panel 3.5mm stereo phone jack with level control. Separate stereo RCA line outputs must also be provided. A TRS 1/4" Headphone Output and Level Control to monitor both Left and Right must be provided on the front panel. Overall gain available from Mic Input to Main Outputs shall be 84dB, and the Mono Output level shall be +23dBu into 600 Ohms.
There shall be an eleven stage LED ladder output VU meter located on the front panel indicating signal levels from 21VU to +6VU and clip when the signal level is 3dB below actual clipping. Each individual channel shall have a clip indicator as well. The mixer unit shall be no higher than two rack spaces and must be fully covered under a five year warranty. The mixer shall have an internal power supply with the power switch located on the rear panel.
The mixer must be manufactured in The United States of America, with a shipping weight of 14 pounds. The mixer shall be the model MX-406, 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.
