Ashly mXa-1502 12-Channel 4-Zone DSP Mixer-Amplifier - Manual (Page 5)

1 Introduction
Thank you for your purchase of the mXa-1502
Mixer Amplifier. This product combines a state
of the art Class D two channel multi-mode
amplifier with eight mic inputs and 4 stereo line
inputs for a total of 16 analog inputs.
The mXa-1502 also comes standard with
comprehensive DSP processing including
ducking, matrix mixing, tone generation,
integrated Ethernet control using Ashly
AquaControl™ software, remote control,
triggered/scheduled events, auxiliary outputs,
and more. Please read this entire manual to
fully understand the features and capabilities
of this product.
1.1 Product Overview
The mXa-1502 is a two-channel x 150W amplifier
with selectable output modes for low impedance
(2/4/8 Ohm), 25V,70V or 100V and two AUX
Outputs, plus 8 mic/line inputs and 4 stereo line
inputs. Other features include comprehensive
DSP, matrix routing and mixing, ducking,
automixing, automatic feedback control, event
scheduling/triggering, and remote control. There
are four independent mixers for matrix mixing,
plus event based logic outputs and fault logic
outputs.
The mXa-1502 is configured and controlled
using server-based Ashly AquaControl ™
software, compatible with most browser
enabled devices. Since AquaControl is pre-
installed and served from every mXa-1502, it is
unnecessary to install the application onto your
computer, phone, or tablet.

2 Installation Requirements
2.1 Electrical and Wiring
The mXa-1502 is designed with a universal
power supply, compatible with 100-240VAC,
50-60Hz. Always use the power cord supplied
with your unit. Do not remove AC ground.
Always use high quality shielded cable for
input signals, and use a balanced input signal
when possible. To avoid possible system noise
or oscillation, avoid running low level signal
wires parallel to speaker outputs or AC wiring,
especially over long distance. Before testing
the system, double check all connections and
settings. Refer to the specifications section
of this manual for input, output, Ethernet, and
other amplifier properties to consider during
installation.
2.2 Mechanical
The mXa-1502 is 1RU, and is designed to fit in
a standard 19-inch equipment rack. Use four
screws when mounting the amplifier to the
front rack rails. Rear support is recommended
for mobile or touring use (see mechanical
drawing). In some installations where the sound
system is exposed to a high level of RF noise or
system-induced oscillation, it may be necessary
to ground the amplifier’s chassis to the rack
enclosure. This is accomplished using star type
lockwashers on the four rack mounting screws,
placed between the amplifier chassis and the
rack rails. These star washers will penetrate
through the amplifier and rack rail finish to
adequately ground the chassis to the rack.
