... CIRCUIT For optimum circuit performance, the nominal output level from the microphone preamplifier or other audio source(s) should be -1 OdBu. The -1 ... With the complete removal of the audio, the turn-OFF ramp of Ar100ms will begin after approximately three (3) seconds. ... The VCAa#39;s current output is then connected to a voltage by a transimpedance amplifier using a low noise SSM- 21 34 op amp.
