1、Balance INPUT (30kΩ) and LINK output:
There is one input and one link output XLR connector in each channel in all models.
The link connector can output signal to another amplifier or other audio devices.
2、Power outputs connected to the loudspeaker. There are two types of connectors
SPEAKON and BINDING-POST in each output channel. Power and impedance of
loudspeaker must be matched to rated value of the power amplifier, beyond the range
of product so that stability will not guarantee. (see Technical specifications ).
3、Earthing / Floating: Controls the separation of the electrical earth from that of the
chassis. Using this selector, it is often possible to break earth loops which can form
when several units are connected together and which can cause hum of other noises.
4、 Mains Input socket: 120Vac 60Hz。
5、 A ir vents
Note: The fan of the PD series cooling system creates a flow of air with the direction
from front to back. That means the air is taken from the opening on the front and is exp
elled through the opening on the front after cooling the heat sinks and transformer.
Attention
must be paid to avoid blocking these openings. A nd never place the amplifier
in which there is not sufficient air circulation.
