Operating Manual - MX-508 Stereo Microphone/Line Mixer
1. INTRODUCTION
Congratulations on your purchase of an Ashly
MX-508 stereo mixer. In one compact rack-mount pack-
age we have combined features, reliability, and sonic per-
formance previously found only in larger and more
expensive mixing consoles. This second generation mixer
is similar to the MM-508, with the addition of output mute
switches on stereo outputs and double or single jack in-
sert points on all input channels.
Other features include optional plug-in isolation
transformers on all inputs, switchable +48V phantom
power, and front panel switching on each channel select-
ing 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 equal-
ization curves. A concentric level and pan control com-
bined 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. Stan-
dard line level outputs on 1/4" connectors, tape outputs
on RCA connectors, and transformer isolated 600 ohm out-
puts on XLR connectors are provided as standard equip-
ment. Ashly still uses professional quality 16mm metal
shaft potentiometers on all controls for greater accuracy
and long life.
2. UNPACKING
As a part of our system of quality control, every
Ashly product is carefully inspected before leaving the
factory to ensure flawless appearance. After unpacking,
please inspect for any physical damage. Save the ship-
ping carton and all packing materials , as they were care-
fully designed to reduce to minimum the possibility of
transportation damage should the unit again require pack-
ing and shipping. In the event that damage has occurred,
immediately notify your dealer so that a written claim to
cover the damages can be initiated.
The right to any claim against a public carrier
can be forfeited if the carrier is not notified promptly and
if the shipping carton and packing materials are not avail-
able for inspection by the carrier. Save all packing mate-
rials until the claim has been settled.
3. AC POWER REQUIREMENTS
The MX-508 mixer will perform normally from
93 to 125 volts AC, 50-60Hz (some export models are
wired for 240 Volts and are labeled accordingly). Use
only properly grounded AC receptacles. To reduce the
risk of ground loop hum, use a central point for system
AC power distribution. In the event of fuse failure, re-
place only with same type fuse. Power consumption is
less than 50 watts.
