SONAMP 2-100 & 12-50 MULTI-CHANNEL POWER AMPLIFIER INSTRUCTION MANUAL

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
RIGHT
amplifiers to share common audio
sources. The loop outputs on the
2-100 amplifier are not buffered.
The number of amplifiers that
IN
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).
OUT
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%.

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

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
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).
NOTE: ALWAYS CHECK LOCAL BUILDING CODES BEFORE
INSTALLING WIRE IN WALLS OR CEILINGS.

Trigger Mode Control 2-100 & 12-50
You can set the Sonamp amplifiers so that they will automatically turn

NOTE: IF EITHER AUDIO OR VOLTAGE TRIGGERS ARE SELECTED,
CLASS 2 WIRING
THE AMPLIFIER HAS A 12 SECOND CYCLE TIME FROM STANDBY
ON
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
Ω
8 MIN
AUDIO
CLASS 2 WIRING 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.
