GETTING STARTED

The Sonance DSP 2-750 MKIII comes ready to play audio out-of-the-box. Sonance suggests the following installation sequence:

Place amplifier in a location away from moisture and temperatures exceeding 100°F (38°C).
Connect audio inputs.
Connect speaker outputs.
Connect network jack with an ethernet cable from the amplifier to a network hub or switch (see the complete DSP 2-750 MKIII User’s Manual and the Sonar guide for complete details).
For IR control (optional), insert a mono 3.5mm plug (tip-positive) into the 3.5mm jack labeled “IR Control”.
For Voltage Trigger, connect trigger lines to the IN+ and IN- terminals on the Voltage Trigger terminal block and connect it.
Connect the power cord.
Confirm audio inputs are muted. Turn the amplifier power switch to the ON position.

SOURCE CONNECTIONS

The DSP 2-750 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. SONANCE DSP2750MKIII DSP Amplifier - switch

VOLTAGE TRIGGER CONTROL
The DSP 2-750 MKIII has a 3-30V (AC or DC) control input. The factory default setting of the amplifier is Always On or Audio-Sense. The Voltage Trigger can be enabled within the Son ARC interface.

IR CONTROL
The 3.5mm jack can 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 2-750 MKIII webpage for specific IR control codes. This feature is always active, and does not need to be enabled in the Son ARC interface.

SPEAKER CONNECTIONS
NOTE : The DSP 2-750 MKIII is capable of driving 4 ohm stereo, 8 ohm stereo, or 8 ohm bridged mono, and 70 Volt loads. Bridged mono load configurations require selection in the Son ARC interface.
NOTE : DSP 2-750 MKIII ships in 70V mode.

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.
For bridged operation, connect speaker wires from LEFT+ to SPEAKER+ and RIGHT+ to SPEAKER-.
Plug the block connector into the amplifier and check that there is no strain on the speaker wire.

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.

RESET BUTTON
Pressing the RESET button between three and ten seconds will reset the network settings to factory defaults (DHCP on). Pressing the RESET button for greater than ten seconds will perform a full factory reset, erasing any EQ changes or other user settings.
