Compressor switch to the right position. The threshold values of the two
break-off points can be regulated with two separate potentiometers. The
potentiometer labeled Threshold
controls the value of the first break-
off point. The potentiometer labeled
2ND slope controls the value of the
second point. The amount of gain
reduction can be monitored on two
LED scales. GR1 shows
the gain reduction at
the first break point.
GR2 shows the gain reduction at the second break point.
The compression ratio and knee value can be selected as
a preset with the Character switch. The positions of the
Character switch use descriptive
names: "Soft", "Medium", "Hard". By
definition, the soft position indicates a
smaller compression ratio with a
gentle knee. The medium position
indicates a much higher compression
ratio with a more angular knee. The
hard position indicates an almost
limiter-like ratio with a sudden knee. The intervention
speed of the compressor is intended to be modified by the time constant
parameter. In Auto mode, the time constants of the compressor are
Fs
THE ONBOARD FILTER SECTION
The basic functions of the filter section include the high-
pass filter. This is actually used to remove low frequency
rumble, a useful addition to any preamplifier. It can be
adjusted automatically depending on the dynamic
conditions of the signal. In addition, four more
stages are available from the fastest to the slowest.
Due to the nature of the compressor, the attack and
release values are set at the same time when
selecting a time constant. In addition, the sound of
the compressor can be fine-tuned by adjusting the
threshold values of the two slopes, along very wide
possibilities.
