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.
