Features
Your new Fully-Balanced, Differential Multi-Channel Amplifier is a state-of-the-
art, high performance audio component built utilizing totally complementary
circuitry from input to output. The high current power supply is driven by
custom-designed, dual torrodial transformers with multiple windings for each
channel. Each output module has 24 discrete output devices, 36,000 µF total
filter capacitance and employs an advanced Opto-coupled protection circuit.
Heat management is provided not by noisy fans, but by custom-designed
heatsinks for each channel.
The Model 7900’s differential design virtually eliminates cross talk, through
a technology known as “common mode rejection”. Compared to single-ended
designs, the Model 7900 requires half the rail voltage for a given power allowing
for increased transient performance. In addition, with a slew rate nearly double
that of a comparable single-ended amp, the utmost control over transients is
maintained ensuring distortion free performance. The result: an amplifier that
remains unequivocally true to the source material.
Input selection occurs automatically as the Model 7900 includes an auto sens-
ing circuit to determine which Input (XLR or RCA), by channel, is being used.
XLR cables provide a fully balanced signal path from Input to output and the
Model 7900’s RCA Inputs utilize a “semi-balanced” design, which provide a
cleaner signal path than traditional RCA connections.
