Volume Level Control
Volume can be controlled from the
individual recessed volume level control
screws, located on the front panel (see
Figure 13). These volume controls balance
the desired sound levels per channel.
Volume can be controlled three different
ways with (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 0
.
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).
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.
NOTE: ALWAYS CHECK LOCAL BUILDING CODES BEFORE
INSTALLING WIRE IN WALLS OR CEILINGS.
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.
Source Connections DSP 2-150
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).
Bridging channels is accomplished using the software. On
the second page 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
bridged 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.
