3> Mode option and signal cable connection,
A S tereo connecting mode:
B Mono paralleled mode:
C Bridged mode:
16
When LF cutting is at 5Hz, the audio signal
can be amplified really.
Like the right drawing:
Like the right drawing:
Connecting direction:
Put the switch of mode at stereo,
like the right picture:
Under the stereo mode, the signal on channel A and
channel B is independent, the signal to channel A is
just for channel A, the signal to channel B is only for
Channel B. Like the right drawing:
Put the switch of mode at PARALLEL, like the
below picture:
Under the mono parallel mode, the effect of input
signal from channel A and channel B is same. The
signal on input channel A can be provided to output A,
also to output B. The signal on input channel B not only
provide to output A, also to output B, But please not
input the signal from channel A and B at the same time.
Note: The mono parallel mode just means the
parallel of input signal. Never parallel the output
terminals, Like the
drawing: right
Put the switch of mode at BRIDGE, like the
right picture:
Under the bridged mono, signal just can be input from
channel A, no voice if input from channel B, the anode
of output A is the anode of bridged output, the anode
of output B is the cathode of bridged output.
like right drawing:
