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 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 Equivalent Input Noise (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. Vari-

able 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. 

The MX-508 combines traditional Ashly quality with 

internally modular construction in a package offering 

outstanding value and reliability. 

MX-508 Features:
•  3-Band, channel EQ w/ sweepable mid freq center

•  Convenient, 3.5mm stereo line in jack on front panel 

for MP3 players and smartphones

• 2 AUX sends per channel

• Insert jacks on each channel

•  Independent mono output with level control
