1）STR/Stereo LED (Blue)
Indicates that the amplifier is working in Stereo mode.
2）PAR/Parallel LED (Blue)
Indicates that the amplifier is working in parallel mode. In parallel mode, you have to apply the signal only
to the CHA (Channel A) input of the amplifier. The signal input is from CHA, but the signal outputs are
same as in Stereo mode, i.e. from CHA & CHB outputs, connecting to two speakers.
3）BTL/Bridge LED (Blue)
Indicates that the amplifier is working in bridge mode. This means that both channels are switched
together in series to act as mono amplifier. The output power is almost three time of that compared to the
separate channels. In bridge mode, you have to apply the signal only to CHA input of the amplifier.
4）PROT (Protect) / YELLOW
The LED will be on under the following 3 conditions:
4-1）During first few seconds after switching on/off the amplifier the LED is on.
