Figure13:VolumeLevelControl
Figure11:BridgingChannels
Volume Level Control
Volume can be controlled from the individual recessed volume level
control screws, located on the front panel and from SonARC (see
Figure 13). These volume controls balance the desired sound levels
perchannel.Volumecanbecontrolledthreedierentwayswith
SonARC v2 (see Figure 14).
1. Output volume 2. Turn on volume 3. Maximum volume
Output volume ranges between -70 to 12. The volume level
controls are set at +12 by default.
Source Connections DSP 2-750 MKII
On the left side of the rear panel are the audio inputs for the left
and right channels. In addition to the left and right inputs there are
also loop outputs for each channel. The loop outputs allow multiple
amplierstosharecommonaudiosources.Theloopoutputson
theampliersarenotbuered.Thenumberofampliersthatcan
be connected in series will depend on the output level of your audio
source.ThesourceconnectedtotheLEFTandRIGHTLINEIN

For the best sound you should use
premium speaker wire that complies
withreratingcodes.Besureto
check local codes governing wire
that may be installed within walls or
ceilings.Sonampampliersare
stable with any reputable brand of
speaker wire or cable. The Sonamp
ampliersusespeakerblock
connectors that can accommodate
up to 12 gauge wire (see Figure 9).
NOTE: ALWAYS CHECK LOCAL BUILDING CODES BEFORE INSTALLING
WIRE IN WALLS OR CEILINGS.

the output setup area to bridge mode and make your selections
with the drop down buttons.
1.Usetheleftaudioinputwhenoperatingtheampliersoutputin
bridge mode (see Figure 10).
2.SelectONinthebridgemode(seegure10).
3.Connectthespeaker’s“+”leadtotheleftsideoftheconnector

4.Connectthespeaker’s“–”leadtotherightsideoftheconnector
marked“+”(seeFigure11).
5. Connect the line level audio input to the LEFT channel input on
 theamplier.
IMPORTANT: THE MINIMUM SPEAKER IMPEDANCE FOR BRIDGED
OPERATION IS 8 OHMS. DO NOT OPERATE A ZONE IN THE BRIDGED MODE
INTO A SPEAKER THAT IS LESS THAN 8 OHMS NOMINAL IMPEDANCE.
