As8 Technical Notes - AKG AS8 Bedienungsanleitung

C/L In radio button - shows the current status of the compressor/leveller system. If the Remote radio
button is selected, selecting the C/L In radio button will activate the compressor/leveller system.
When the Local radio button is selected, the C/L In radio button will be disabled, but will indicate
the current state of the Compressor/Leveller In/Out switch on the front panel of the AS8.
C/L Out radio button - shows the current status of the compressor/leveller system. If the Remote
radio button is selected, selecting the C/L Out radio button will deactivate the compressor/leveller
system. When the Local radio button is selected, the C/L Out radio button will be disabled, but will
indicate the current state of the Compressor/Leveller In/Out switch on the front panel of the AS8.
Comp/Lev Attenuation - shows the gain reduction which is applied to each channel as a result of
compressor/leveller action.
Comp/Lev Threshold - shows the current threshold level of the compressor/leveller system.
Thr scroll bar - adjusts the threshold of the compressor/leveller system. If the Remote radio button
is selected, this control is active. If the Local radio button is selected, the control is inactive.

7. AS8 Technical Notes

The AS8 uses a straightforward analog signal path to provide excellent audio performance. This is
coupled with a sophisticated microcontroller to implement both the automatic mixing and the
compressor/leveller algorithms. The Adaptive Level Proportional automatic mixing algorithm is
used by the AS8. This algorithm uses the signal level pattern at the microphones to derive a pat­
tern of channel gains. For instance, if only one microphone channel is being spoken into, its level is
dominant and that channel gets most of the system gain, while all other channels are turned
down. If more than one microphone is active, they share system gain according to their relative
levels. A "skewing" function gives some advantage to microphones which are active over time, to
minimize interruptions from transient noise at other microphones. Since each channels' gain is
apportioned continuously based on its relative level, no abrupt gain changes are made. This
makes the automatic action virtually inaudible.
The Compressor/Leveller function uses a combination of the short-term and long-term signal dy­
namics of the signal to determine the optimum amount of gain reduction in any situation. The
effect of the function is to control both the average program level (for consistent long-term sound
system level) and to minimize any large short-term deviations. The gain reduction function is gated,
which means that there are no noise ups associated with program signal pauses.
