1. INTRODUCTION

Congratulations on your purchase of an Ashly

508 stereo mixer . In one compact rack-mount package we

have combined features, reliability, and sonic performance

found only in larger and more expensive mixing consoles .

This third generation mixer utilizes a universal 100-240VAC

switching power supply, and adds a 3 .5mm front panel stereo

line input jack .

Other features include output mute switches, dual jack

insert points, switchable +48V phantom power, and front

panel switching on each channel selecting between mic or

line input . Three-band equalization with a fixed frequency

low and high shelf and a tunable mid-range control provides

perfect true-reciprocal equalization curves . A concentric level

and pan control combined with a concentric pair of auxiliary

sends complete each input channel .

Ultra low-noise summing amplifiers combine the

channel signals for the main and send outputs . Two 10-segment

LED arrays monitor main or aux outputs . Standard line level

outputs on 1/4" connectors, stereo pre-fader line outputs on

RCA connectors, and transformer isolated 600 ohm outputs on

XLR connectors are provided as standard equipment . Ashly

still uses professional quality 16mm metal shaft potentiometers

on all controls for greater accuracy and long life .

The lightning flash with arrowhead

symbol, within an equilateral triangle, is

intended to alert the user to the presence

of uninsulated "dangerous voltage" within

the product's enclosure that may be of

sufficient magnitude to constitute a risk

of electric shock to persons.
