Bridging Channels 2-100 & 12-50
Trigger Mode Control 2-100 & 12-50
You can set the Sonamp amplifiers so that they will automatically turn
ON when it receives an audio signal, when it receives a control voltage
from an external source, or to remain on and not enter standby.
NOTE: IF EITHER AUDIO OR VOLTAGE TRIGGERS ARE SELECTED,
THE AMPLIFIER HAS A 12 SECOND CYCLE TIME FROM STANDBY
TO PLAY AN AUDIO SIGNAL. THIS IS NORMAL AND REQUIRED TO
COMPLY WITH THE EU < .5 WATT ErP DIRECTIVE. (EC/1275/2008).
SELECT OFF TO BYPASS THIS FEATURE. SEE POWER CONSUMPTION
TABLE FOR IDLE POWER USE (SEE FIGURE 7).
Auto On Triggering - Three Position Switch
AUDIO
In this mode, the amplifier will automatically turn ON when the
minimum audio signal of 2.5 mV is detected at any of the inputs
(Buss or LOCAL on the 12-50). This takes 12 seconds. The amplifier
will turn OFF after 15 minutes of no input signal on any of the inputs.
VOLTAGE
When AUTO ON switch is in the left position, power will only turn
on with a VOLTAGE of 3 to 30 volts AC or DC. Connect the trigger
voltage source to the input of the voltage trigger using the left side
of the green block connector. This takes 12 seconds.
OFF
When AUTO ON switch is in the center position, OFF, the amplifier
will remain ON and will not go into standby mode.
NOTE: WHEN THE AUTO ON SWITCH IS SET TO OFF THE
AMPLIFIERS POWER SAVING FEATURE WILL BE DISABLED.
12V Trigger Output
The Sonamp has a 12V OUTPUT 2-wire screw connector found on
the right side of the green block connector that provides 12V DC
whenever the amplifier is ON.
NOTE: THE CURRENT DRAW ON THE 12V TRIGGER OUTPUT
CONNECTION SHOULD NOT EXCEED 200mA.

Volume Level Controls
2-100 & 12-50
On the rear panel of both the 2-100 and
12-50 individual channel volume controls
are provided (see Figure 12). These
volume controls allow balancing the
desired sound levels for various zones, or
balancing the outputs from right and left
channels to compensate for various room
characteristics or seating arrangements.
The volume controls are set at 50%.
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 13).
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 2-100
On the left side of the 2-100 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
2-100 amplifier 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 11).
FIGURE 11: SONAMP 2-100
LEFT AND RIGHT LINE INPUTS
12-50
Use the left LOCAL Input or the left Buss Input when operating the
amplifiers output in bridged mode. Use the DIP switch to select the
input you would like to assign to the bridged output.
2-100
Use the left audio input when
operating the amplifiers output
in bridged mode.
1. Set the zone’s BRIDGE switch to the ON position (see Figure 14).
2. Connect the speaker’s “+” lead to the left side of the connector
marked “+” (see Figure 15).
3. Connect the speaker’s “–” lead to the right side of the connector
marked “+” (see Figure 15).
