The MX-508 is an 8-input stereo rackmountable mixer. Designed for many applications, it has an extensive mix of features for a small unit combined with excellent sound and quiet performance. The MX-508 combines traditional Ashly quality with internally modular construction in a package offering outstanding value and reliability.

The MX-508 features 84dB of gain to ensure full output with low-level or distant microphones. Several years of research went into the microphone preamp and the result is a discrete circuit with better than -129 dBu EIN and very low distortion. Low and High Shelving EQ combined with mid-band peaking EQ tunable from 140Hz and 8 kHz make for a very flexible tone control. Phantom power of +48 VDC is provided for condenser microphones via a switch on the front panel. Each input has its own 20dB pad switch. Variable gain trim and Mic/Line selection switches are also found on each input channel. Rounding out the list of standard input features are a Peak Clip indicator, two Aux Sends (factory-set with one pre-EQ and level and the other post-EQ and level, these sends may be modified by a qualified technician), in/out channel patching, level and pan controls, and both balanced XLR microphone and TRS Line inputs.

Transformer-balanced Left and Right XLR outputs are standard, as are balanced Left and Right TRS 1/4" outs. There is also an independent Mono output with its own front panel level control, as well as a selectable Headphone output with Level Control.

There are Pre-Master Sub In/Out patch points for linking other mixers. Peak Clip indicators are also provided for the Outputs, and the 10-Segment LED Meters may be selected to monitor either Program Left and Right or Aux 1 and 2. Maximum output level is +24dB into 600 Ohms.

The MX-508 also has two Master Aux Sends and two panable Master Aux Returns (one stereo and the other mono). A 3.5mm stereo line in jack on the front panel offers a convenient input alternative for MP3 players and smartphones with level control to the Mains or to Aux 1. Stereo RCA Outputs are also provided.
