CH-2
Input level controller for channel 2
With this controller you decrease the input level in channel 2 to the respective
dB value indicated on the scale. At the right end stop the attenuation is "0"
and the full signal is amplified with maximum power.
t
PRO
Indicator for activated circuit protection
This indicator lights up when, in either of the two channels, one of the following
situations occurs:
• 3-5 seconds after switch on since now the speakers are still electrically
disconnected from the power amplifier.
• The temperature of the power amplifier transistors exceeds 85°C.
• There is a malfunction in the device.
y
BR
Indicator for bridged mono operation
In this case amplify both channels together with the signal at input 1.
This leads to a significantly higher single channel output power.
Then do not connect any signals to channel 2.
u
PAR
Indicator for parallel mono operation
In this case amplify both channels with the signal at input 1.
The amplified signal from input 1 is applied to both outputs (CH-1 & CH-2).
i
ON
Switch on indicator light
Lights up while the device is in operation.
o
POWER
ON / OFF switch
Move this switch to the "I" position to switch the device on. During switch on
the circuit protection is activated. After a few seconds you will hear 2 "clicks"
now the speakers are electrically connected with the power amplifier and the
device is ready.
