9. Speaker Outputs
- Connectors are provided to connect speakers to the
amplifier quickly and easily. They are high current rated and provide very stable
and durable contacts. A third Speakon connector in the center is provided to be
used if the amplifier is in the Mono Bridge mode. Every Speakon connector has
Pin 1+ as positive and Pin 1- as negative.
10. Ground lift switch
- Is used to lift the balanced input connector’s
ground/shield from the amplifier's ground. When the signal ground lifted, The
sound source disconnects from the amplifier's ground preventing ground
loops which can generate hum and noise. See the Signal Ground Lift Switch
instructions for more detail.

XLR Input Jacks
- Electronically balanced inputs accept a standard XLR
connector. Pin 1 = shield/ ground, Pin 2 = hot or positive (+) and Pin 3 =cold
or negative (-)

Gain switch
- PS Series amplifier you can select different input sensitivities,
respectively three different voltage gains. The switch settings are 26dB
voltage gain, 32dB voltage gain and 1.4V input sensitivity.
13. Limiter switch
- In some applications it may be necessary to switch off the
built in peak limiter. In normal use, with limiters, the distortion is less than
0.5% even when the Clip LED is flashing. If the loudspeaker system or a pre
connected controller allows the use of an amplifier with more than 0.5% THD
you can switch off the limiter. In this case you should be aware that the
parameter curve at clip level is very steep and you will have only a small
improvement of the usable signal, but a strong increase of distortion.
14. Operation Mode Switch
- Switch is used to set the unit for Parallel mode,
Stereo mode and Mono Bridge mode.
