SOURCE CONNECTIONS
The DSP 2-150 MKIII ships with a Hybrid Input Module
installed from the factory. The Analog (Stereo RCA)
Input is the default source input. If audio is present
on either of the digital inputs, the amplifier will
automatically switch within ten seconds.
SPEAKER CONNECTIONS
NOTE: The DSP 2-150 MKIII is capable of driving 4
ohm stereo, 8 ohm stereo, or 8 ohm bridged mono
loads. Bridged mono load configurations require
selection in the SonARC interface.
1. Connect speaker wire (up to 12 AWG) to the
provided block connector. IMPORTANT: Keep all
wire strands inside the plastic shell. Damage may
occur if speaker wires short together or touch the
amplifier housing.
2. For bridged operation, connect speaker wires
from LEFT+ to SPEAKER+ and RIGHT+ to
SPEAKER-.
3. Plug the block connector into the amplifier and
check that there is no strain on the speaker wire.

GETTING STARTED
The Sonance DSP 2-150 MKIII comes ready to play
audio out-of-the-box. Installers have the option to
set the amplifier up using the physical controls for
customization or the SonARC web interface (ethernet
interface required). Sonance suggests the following
installation sequence:
1. Place amplifier in a location away from moisture
and temperatures exceeding 100°F (38°C).
2. Connect Audio Inputs.
3. Connect Speaker Outputs.
4. Choose a configuration method:
• For physical controls set up, set the EQ Preset
Bank and Selection knobs as needed (see “EQ
PRESETS” section).
• For SonARC, connect an ethernet cable from
the amplifier to a network hub or switch (see the
complete DSP 2-150 MKIII User’s Manual and the
SonARC guide for complete details).
5. For Voltage Trigger or IR control, insert a mono
3.5mm plug (tip-positive) into the 3.5mm jack
labeled “12V/IR”.
6. Connect the power cord.
7. Confirm audio inputs are muted. Turn the amplifier
power switch to the ON position.
EQ PRESETS
The amp has DSP presets for optimization when used
with Sonance speakers. Select from available DSP
EQ presets knobs on the back panel. Refer to the EQ
Preset sticker on the top of the amplifier to find the
corresponding Bank (A-G) and Selection (1-7), and
turn the knobs to the corresponding settings. Preset
A1 is a flat EQ by default. All EQ presets can be further
modified through the SonARC interface.
12V/IR CONTROL
The DSP 2-150 MKIII has a multi-function 3.5mm mono
input jack. The amplifier can be triggered on from
a sleep state with the application of 3-12V DC input
(>50mA). This feature is enabled within the SonARC
interface.
The 12V/IR 3.5mm jack can also be used to receive IR
commands from a distribution box or self-powered
IR sensor. The amplifier does not provide a voltage to
IR sensors. Refer to the DSP 2-150 MKIII webpage for
specific IR control codes. This feature is always active,
and does not need to be enabled in the SonARC
interface.
POWERING THE AMPLIFIER
Plug the provided 14 gauge EIA standard 120 Volt
grounded power cable into the IEC power connector.
IMPORTANT: Do not plug the power cord into the
wall outlet until all system connections are made.
