    FRONT PANEL 1. Input “A” and “B” level controls These controls are normally set to their “0"-marked (detent) center position. If needed or desired, the controls can be used to individually adjust the input levels of the channels “A” and “B”. The green “Signal” LEDs indicate that audio signals are present at the inputs. The red “Peak” LEDs light whenever the audio signal is clipped inside the AC which might result in distortion.
  • Page 5 FRONT PANEL 7. Sub Out Mono control The control is normally set to its center (0dB) position. This control is used to adjust the loudness level of the summed low-frequency audio signal of the two channels “A” and “B”, which serves to feed a connected monaural sub woofer power amplifier. The “Mute” switch attenuates the Sub Out Mono audio signal, which allows to easily check the entire sound reinforcement system.
