mXa-1502 • Operating Manual
1 Introduction
Thank you for your purchase of the mXa-1502
Mixer Amplifier. This product combines state
of the art Class D multi-mode amplifier design
with eight mic inputs and 4 stereo line inputs
for a total of 16 analog inputs.
The mXa-1502 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 150W power
amplifier with independently selectable output
modes for low impedance (2/4/8 Ohm), 25V,70V,
or 100V, plus two AUX line level outputs, each
driven by one of four independent mixers. Each
mixer front end has access to the same eight
quality mic/line inputs and four stereo line inputs.
DSP includes matrix routing and mixing per mixer,
ducking, EQ, FIR filters, limiting/compression,
noise gates, automixing, autoleveling, ambient
noise compensation, crossover, delay, and more.
Add to all that event scheduling/triggering, remote
control, event based logic outputs, fault logic
outputs, and more.
The mXa-1502 is configured and controlled
using server-based Ashly AquaControl™
software, compatible with most browser
enabled devices. AquaControl is served from
the mXa-1502, installing an application on
your computer, phone, or tablet is unnecessary.

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).
