7 – Handling & controls
1. Input
:
The input stage amplification is between non stepped values of 0 (-∞ dB) and 10 (+16
dB). The more input gain you choose, the more harmonic distortion is added to the
signal. The tube stage provides differences from a pure, clean to distorted and saturated
sound.
2. Output
:
Every compression causes a loss of volume. The output-stage helps to compensate the
gain reduction with a 26dB gain reserve. The interaction of the input and output stage
offers sound variations depending on how much the input or output tube is driven to
saturation or even distortion (input stage).
In amp-only-mode the compressor-section is skipped completely but the signal still
passes through the circuitry. You can design your sound by using the input and output
controls. The spectrum of coloration without compression ranges from-natural clean to
aggressive distortion.
3. Threshold
:
If the input level exceeds the adjusted threshold, the compression will start immediately.
The threshold control offers non stepped values between 0 and 10.
4. Attack:
The rotary control determines in ten steps the attack-time of the compressor. Position 1
is marked with the character ‚F‘ for
fast
transient response, position 10 uses the
character ‚S‘ for
slow
operation.
5. Release:
This rotary switch is divided in ten steps to control the release time. The values also
range between ‚F‘(ast) and ‚S‘(low).
6. Sidechain Control/Amp Only
The side chain controls define frequencies of the high pass filter, which affect the control
signal only. As a result high-energy bass frequencies from the side chain signal will not
affect the compressors operation. There are four frequencies: 54, 74, 110 and 160 Hz
and the flat-position, which switches the filter off.
As mentioned previously, the amp only-mode leaves only input and output controls
operational. The signal still passes through the audio path (transformer, tubes,
capacitors) but skips the compressor section.
