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amplier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amplier
orotherinternalproblemwiththeamplier.
Front Panel
Power Button
Thepowerbuttonturnstheamplieronando.WhentheSonance
logo power button is engaged, the power button is illuminated
solidwhite.ThismeanstheamplierhaspowerandisturnedON
and ready to operate. When the Sonance logo button is slightly
dimmed,theamplierisinstandbymode.WhentheSonance
logobuttonblinkswhite,theamplier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amplierhasvolumeadjustmentscontrolled
in the SonARC software or on the front panel recessed volume
controls.Outputvolumewillreecttheoptionlastadjusted.The
DSP2-150MKIIampliershipsatthe+12ormaximumvolume
level.

Line Inputs/Loop Outputs
TheDSP2-150MKIIamplierhaslineinputsandloopoutputs.
Theloopoutputsarenonbuered,themaximumnumberof

Speaker Connections
TheremovableblockconnectorsusedontheSonampampliers
will accept up to 12 gauge wire. Follow the connection layout on
therearpaneloftheamplier.Makesurenobarewirescomein
contactwiththeamplier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.
CAUTION: FOR CONTINUED PROTECTION AGAINST FIRE, REPLACE THE
FUSE WITH ONLY THE SAME TYPE AND RATING.
Power Cord
The Sonamp DSP 2-150 MKII features a removable power cord.
Plug the female end of the power cord into the Power Cord
Connectorontheamplierrearpanelandplugthemaleendintoa
grounded wall socket.
DONOTplugtheamplier’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amplierofthecurrent
necessary for full operation.

Auto On - Voltage In/Out Trigger
TheSonampamplierscanbeturnedonandousing3-30volts
AC or DC. The Voltage Output supplies a 12 volt DC signal to
controladditionalampliersorotherequipment.Theincludedred
wire is to prevent the amp from accidentally entering sleep mode
during setup. Remove the red wire when using the voltage trigger.
IR Control
IR control is established via the 3.5mm mono mini input jack on the
rearoftheamplier.IRcommandsincludevolume,mute,group,
powerandinputoptions.IRcontrolsglobalOn/O,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/O,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.
