Drawmer 1973 Three Band Stereo FET Compressor - Manual (Page 6)

6 DRAWMER 1973 O
PERATOR’S M ANUAL
CONTROL DESCRIPTION
X-OVER FREQUENCIES
The 6dB per octave crossover frequencies
determine the points within the frequency
spectrum one band stops to process audio, and
another band takes over.
Low X-Over Frequency:
50Hz - 1.3kHz
Sets the frequency point at which the split
between low and mid bands occurs.
High X-Over Frequency: 1kHz - 14kHz
Sets the frequency point at which the split
between mid and high bands occurs.

The 1973 shares similar parameters to a standard full band compressor, such as the Drawmer 1968, the difference being
that the stereo signal is split into low, mid and high bands, each one processed separately without affecting the other,
and then summed back into a stereo signal again before output.
As you would imagine a multiband compressor
could become a very intimidating beast due to
the number of controls, however, the 1973 as been
layed out to be as intuitive to use as possible.
Anyone familiar with the Drawmer 1960’s range,
the S2 and especially the S3 compressors should
be immediately at home.
Essentially the 1973 comprises the three low, mid
and high compressor bands to the left of the unit
with the crossover frequency knobs inbetween.
These bands are all almost identical, the only
difference being the Big and Air switches. To the
right of the unit the meters and output sections
are located (see below diagram).
The three bands are almost identical - the only difference being the
inclusion of ‘Big’ (8) and ‘Air’ (9) on the low and high bands respectively.
