SPECIFICATIONS

The VAC System has been developed with the critical ear as the major arbiter of quality, with both conventional

and unique measurements providing insight and guidance as necessary. The lack of emphasis on measurements

is due to the fact that engineering's arsenal of equipment and techniques do not operate on the pattern

recognition principles that control human perception of sound.

In the immortal words of Daniel von Recklinghausen, if it measures good and sounds bad it is bad. If it

measures bad and sounds good you've measured the wrong things.

For those concerned with test bench performance, the following describes typical measured performance of a

PA100/100 operated at 120 VAC, 60 Hz.

Power Output:100 watts continuous average power at 1 kHz into 8 ohms connected to the 8 ohm

tap, both channels driven; 103 watts one channel driven.

Frequency Response:down 0.5 dB at 5 Hz and 64 kHz, ref 0 dB = 1 watt @ 1 kHz.

down 3.0 dB at 3 Hz and 115 kHz, ref 0 dB = 1 watt @ 1 kHz.

Power Bandwidth:down 0.5 dB at 12 Hz and 50 kHz, ref 0 dB = 100 watts @ 1 kHz.

down 3.0 dB at 8.5 Hz and 85 kHz, ref 0 dB = 100 watts @ 1 kHz.

Distortion:< 0.25% THD at 1 kHz 10 watts

Noise:< 1.5 mv at the output, S/N ratio > 84 dB

Sensitivity:0.775 volts input for full power output

Negative Feedback:Loop feedback is fixed at approximately 6 dB regardless of output tap selected.

Absolute Polarity:Does not invert signal polarity.

Fuse:Slo-Blow type, 4A for 100 & 120 Volt configuration, 2A for 220 & 240 V.

Power consumption:300 watts at idle, 516 watts with both channels driven to full power.

Dimensions:18 " width x 15 " depth x 7.5 " height
