1. Input Select Switch:

Select either Balanced or Single Ended audio 

input.

2. Balanced Audio Input: 

This input connector accepts standard XLR (pin 

1 = Ground, pin 2 = Positive, pin 3 = Negative) or 

1/4” Phone plugs (sleeve = Ground, tip = Positive, 

ring = Negative).  Use quality, 100% shielded 

cables with gold plated connectors.

3. Single Ended Audio Input:

This input connector accepts standard ‘RCA’ or 

‘Phono’ connectors. Use quality, 100% shielded 

cables with gold plated connectors.

4. Gain Select Switch:

The optimum gain setting will depend upon the 

source pre-amp operating level, and or personal 

preference.

The 29dB setting is used when the source is 

single-ended or from a transformer coupled 

balanced source. This is the typical for single 

ended or un-balanced operation. The 29dB 

setting provides the most amplifier gain and 

equates to 100w @ 8 ohms output for a 1V input 

(noise -115 dB). 

The 23dB setting is used when the source 

output is actively balanced. This is the typical 

setting for balanced operation. Or use this 

setting whenver less gain is required.  The 23dB 

setting equates to an output of 100w @ 8 ohms 

for 2V input (noise -119 dB). 

The noise is referenced in dB below rated 

output. Different input configurations result 

in slightly different noise readings. The above 

noise ratings represent minimum readings. 

Actual readings may be better.

5. Channel Level Attenuator (PRO 

ONLY): 

The level control will attenuate the input signal 

level from 0dB through  -14dB.
