XLR INPUTS
1. Balanced input connections
XLR input connectors are electronically balanced;
XLR input connectors should be wired as follow:
Pin 1 Groud/ shield
Pin 2 positive (+)
Pin 3 negative (-)
2.Unbalanced input connections
To connect an input to an unbalanced source, it is possible to connect Pin1 and Pin3 in the XLR
plug at the amplifier end of the cable. However, a better method is to connect Pin3 to the shield at
the sourse end of the cable, as this usually results in better hum and noise rejection. Balanced input
connetions are recommended whenever possible.
SPEAKON OUPTPUTS
Each channel accepts a normal 2-wire cable.
Stereo and parallel mode-
connect every speaker to the amplifier channel, and select stereo
or parallel mode as follow
Each channel is with a balanced XLR input connector. It's connected in a
standard way and can be changed quickly and easily. Balanced connect is
recommended so as to reduce the AC noise and interrupt, especially when
using long cable. Unbalanced connect should be used with short cable, and
the signal resistance should be no more than 600 ohms.
OUTPUT TERMINAL SAFETY WARNING!
Do not touch output terminals while amplifier power is on.
Turn off the amplifier before connecting, or else there will be risk
of hazardous energy!
Output Voltage Peak Limiter(VPL)
Voltage Peak Limiter (VPL) is a unique feature in D series amplifiers. It is used to select the maximum
power available on each output channel. The VPL allows you to set the correct output power for the
connected speakers to get to its best performance. The correct configuration is depended on the
system type and the load of connected channel.
If you choose a lower VPL setting, you only reduce the output voltage. At the same time, this allows
more current headroom for low-impedance loads. The amplifier thus runs at higher efficiency, with
a significantly reduced risk of going into thermal protection.
There's no bridge mode on this amplifier.
Do not support hot-plugging. Only plug in or out input signal when the power is off.

SELECTING STEREO OR PARALLEL MODE
T
he amplifier can be set for normal Stereo operation or Parallel input Mode.
Stereo Mode
-
Each channel remains independent. The amplifier may be used
for two different signals.
Parallel Mode
-
This setting connects two input signal ( for 2-channel amplifier)
or four input signal ( for 4-channel amplifier)l together. One signal feeds both channels
(2-channel amplifier) or 4 channels(4-channel amplifier). Controlling by the input connector
and gain of channel A.
For 3 channel amplifier, it's without sucn function.
Do not connect different inputs to any side that opposites the channel
when operating in Parallel Mode.
