Bridging Channels DSP 2-750 MKII
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 different 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
amplifiers to share common audio sources. The loop outputs on
the amplifiers are not buffered. The number of amplifiers 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
Inputs pass through the LEFT and RIGHT LINE Outputs
(see Figure 12).

Speaker Connections
For the best sound you should use
premium speaker wire that complies
with fire rating codes. Be sure to
check local codes governing wire
that may be installed within walls or
ceilings. Sonamp amplifiers are
stable with any reputable brand of
speaker wire or cable. The Sonamp
amplifiers 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.
Figure 9
Speaker Connections
Bridging channels is accomplished using the SonARC v2 software.
On the second page in the software under IN/OUT Settings, go to
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 amplifiers output in
bridge mode (see Figure 10).
2. Select ON in the bridge mode (see figure 10).
3. Connect the speaker’s “+” lead to the left side of the connector
marked “+” (see Figure 11).
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 amplifier.
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.

IMPORTANT: USE CAUTION WHEN SETTING VOLUME LEVELS EITHER ON
THE AMPLIFIER OR AN AUDIO SWITCHER AS NOT TO OVERDRIVE AND
POSSIBLY DAMAGE SPEAKERS. VERIFY ALL SOURCES AS OUTPUT
VOLTAGE VARIES FROM DEVICE TO DEVICE.
