Input/Output Lights
When each channel is active, the LED will light green as long as a
signal is present. Input/Output LEDs blinking red indicate that the
associated channel is being over-driven. Input/Output LEDs turning
solid red indicate that the amplifier is in protect mode. While in
protect mode the LED lights will periodically light green to retest the
output to determine if the issue has been resolved. Protect mode
could be caused by a short in the wire, overheating of the amplifier
or other internal problem with the amplifier.
Front Panel
Power Button
The power button turns the amplifier on and off. When the Sonance
llogo power button is engaged, the power button is illuminated
solid white. This means amplifier has power and is turned ON and
ready to operate. When the Sonance logo is slightly dimmed, the
amplifier is in standby mode. When the Sonance logo blinks white,
the amplifier power supply is in thermal protection. In this situation,
the channel LEDs will also illuminate red, indicating that the power
supply is in thermal protection mode.
NOTE: UPON INITIAL POWER UP, THERE WILL BE A 9-12 SECOND DELAY
BEFORE SOUND IS HEARD DURING THE BOOT UP CYLE. THE INDICATOR
LEDS WILL ILLUMINATE RED, THEN GREEN, THEN GO OUT. THIS IS NORMAL.
NOTE: WHEN ANY OF THE LEDS ARE RED, TURN THE AMPLIFIER OFF
IMMEDIATELY. DETERMINE THE CAUSE OF THE PROBLEM BEFORE
TURNING THE AMPLIFIER BACK ON.
Volume Level Control
Each channel on the amplifier has volume adjustments controlled
in the SonARC software or on the front panel recessed volume
controls. Output volume will reflect the option last adjusted.
Rear Panel
Line Inputs/Loop Outputs
The DSP 2-750 MKII amplifier has line inputs and loop outputs.
The loop outputs are non buffered, the maximum number of
amplifiers that can be looped together will depend on the output
capability of your source component
Speaker Connections
The removable block connectors used on the Sonamp amplifiers
will accept up to 12 gauge wire. Follow the connection layout on
the rear panel of the amplifier. Make sure no bare wires come in
contact with the amplifier chassis. When bridging channels, use the
two outside connections on each connector. The positive wire from
the speaker should be on the left side connection and the negative
connection should be on the right side. To avoid shock or shorts
use the included block connector protective cover (see Figure 5).
CAUTION: FOR CONTINUED PROTECTION AGAINST FIRE, REPLACE THE
FUSE WITH ONLY THE SAME TYPE AND RATING.
Power Cord
The Sonamp DSP 2-750 MKII features a removable power cord.
Plug the female end of the power cord into the Power Cord
Connector on the amplifier rear panel and plug the male end into a
grounded wall socket.
DO NOT plug the amplifier’s power cord into a convenience outlet
on any other audio or video component. If you need to use an
extension cord, use only a heavy duty (14 GAUGE OR LARGER)
extension cord to avoid starving the amplifier of the current
necessary for full operation.

Auto On - Voltage In/Out Trigger
The Sonamp amplifiers can be turned on and off using 3-30 volts
AC or DC. The Voltage Output supplies a 12 volt DC signal to
control additional amplifiers or other equipment.
IR Control
IR control is established via the 3.5mm mono mini input jack on the
rear of the amplifier. IR commands include volume, mute, group,
power and input options. IR controls global On/Off, group volume,
muting and input source selections. Connectivity can be seen with
IR status light.
IP Control
IP control is via the RJ-45 input. IP controls power On/Off, volume,
muting and input source selections for either global control or
group control.
AC Fuse Holder
To replace the fuse, unplug the power cord from the Power Cord
Connector and use a screwdriver to remove the fuse holder.
DSP 2-750 - 15 amp AC.
