Operating Manual - MQX-2310, MQX-1310, and MQX-2150 Graphic Equalizer

1. INTRODUCTION

Congratulations on your purchase of an  Ashly

MQX series graphic equalizer.  The MQX series follows
our popular GQX equalizers with the same quality you
expect from Ashly, only in a smaller package. Where most
“mini-equalizers” use 20mm faders,  Ashly uses custom
built professional quality 25mm faders for maximum reso-
lution and long life.   The audio connectors include 1/4"
jacks, XLR,  and terminal block on both inputs and out-
puts, along with a provision for lifting input ground.  We
continue using “Q” enhanced Wein bridge filters and in-
terleaved summing for constant “Q”, low ripple, and mini-
mum filter interaction.

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

A standard IEC-320 AC inlet is provided on the

rear panel of each MQX equalizer to accept the detach-
able power cord shipped with the unit.  Units distributed
within the United States are preselected for 120VAC, 60Hz
and should be plugged into a standard NEMA 5-15 3-
wire grounded AC receptacle.  Most units distributed out-
side the US are preselected and labeled for 240VAC,
50-60Hz and are shipped with the appropriate power cord.

All MQX equalizers will perform normally from

95 to 125 volts AC.  An internal line fuse is used.  In the
event of fuse failure, refer to a qualified service techni-
cian for servicing.  Power consumption is 18 watts.

4. SECURITY COVERS

For installations where it is desirable to protect

the front panel controls from tampering or accidental
misadjustment, use the  Ashly security cover, which is
available in both single and double rack space sizes.  In-
stallation is simple and does not require removal of the
equipment from your rack.  See your  Ashly dealer for
details.
