Sleep LED turns on when the amplifier is in
sleep mode, as configured in software. To set
sleep mode on/off, plus set the audio inactivity

The Disable LED is lit when the power switch
has been disabled from software.
3.7 Power Switch
The power switch turns the unit on or off, and
also flashes when in standby. The power switch
can be disabled in software. To disable the
power switch, go to [Settings>Panels>Front

Rear Panel Features

4.1 Balanced Mic/Line Inputs
Use these for wiring 3-wire balanced inputs (G,
+, -) using the provided Euroblock connectors.
If an unbalanced input signal is used, wire its
hot signal to (+), its ground to (-), and leave the
mXa-1502 input ground pin for that channel
unconnected. Maximum input level is +21dBu.
4.2 -10dBV Unbalanced Stereo Line
Inputs
These RCA jacks are used for stereo line level
inputs (-10dBv). Note: Unbalanced line level
sources may reference their outputs to a
different ground than this amplifier, creating
the potential for ground loop hum. Always use
short cable lengths for unbalanced signals,

routed away from AC, video, or data cables, and
make every effort to use a common grounding
point for all devices. In the event there is still
ground loop hum, isolate the unbalanced input
signal by using an in-line isolation transformer.
4.3 AUX Out 1 & 2

AUX outputs offer additional and independent
post-DSP signals for driving other amplifiers or
processors. AUX outputs are configured in the

balanced signals, maximum output level is +21dBu.
4.4 VCA 1-3
A VCA (voltage controlled amplifier) is used to
remotely control one or more
placed in the software signal chain. Ashly WR-
1, WR-1.1, and WR-1.5 remotes can be wired
to VCA 1-3 input pins to control the assigned
VCA gain. See
4.5 Data
These four pins for serial data control are inactive,
reserved for future remote control devices. No
currently available Ashly remote hardware is
compatible with this port.
4.6 Trigger 1-8
Eight contact closure pins can trigger mXa-
1502 events or action sequences that have
been programmed in software. See section
6.1c, 6.4, and
event action types.

VCA gain blocks

4.7 GPO 1 & 2
These pins provide logic outputs referenced to
the ground* and +5V* pin found on the same
connector. Logic output changes are generated
from presets, triggers, or scheduled events,
and can be assigned high or low in software.
See section 7.3 for example.
4.8 Amp 1 & 2 Fault
Fault output pins are logic-high (+5V*) when
the amp channel is on and ok, but transition to
logic-low (0V*) when the amp channel is off or in
a protect/fault state. See section 7.4
*For GPO and fault outputs, the +5V pin can source
up to 30mA to drive an LED or control system input.
The ground pin can sink up to 200mA to provide a
ground path for an external relay system.
4.9 Standby
Wire the Standby pin to a remote switch to a
place the amp into standby mode. The power
switch LED flashes when the amp is in standby
mode. Standby pin contact polarity can be set in
software for standby when the switch is closed, or
standby when open. See section 7.5
4.10 Ethernet Port
The RJ-45 connects to an Ethernet network
or directly to a PC for Ashly AquaControl™
software control.
