ADVANCED INSTRUMENTATION INPUT

The Advanced Instrumentation Input has been incorporated from

the legendary

PrecisionPower

2500F1

. This circuit completely

isolates the chassis ground from the audio circuit of the amplifier

and reduces noise radiated into your signal cables by up to 40dB.

This is equivalent to a noise reduction of approximately one hundred

times what the noise level would be without this circuitry. It provides

all the benefits of a true balanced line without the need of any

special cables (see diagram below). This type of input works with

any conventional RCA cables.
