ADVANCED INSTRUMENTATION INPUT
The Advanced Instrumentation Input has been incorporated from the legendary Precision PowerTM 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.
QBASS
For extra BOOM from your system, we’ve developed the QBASSTM bass control circuit.
The QBASSTM control is located on the end plate panel, and allows you to add up to 18dB of boost centered
at 40Hz by rotating the control clockwise.
