The 2021 offers the sound and much of the flexibility of the legendary C-1
compressor in a fast and friendly package. Variable control of all the major
parameters is retained: input gain, threshold, ratio and gain make-up, while
attack and release times are switchable for "fast" or "slow" modes. Like the C-
1, the 2021's attack and release time constants are program dependent, so in
reality the choice of two modes becomes a time saving and versatile
rationalisation of facilities.
The 2021 features two ECC83 / 12AX7A valve stages per channel running at 150v
DC. Both stages form part of the gain control element, which like the C-1 is
our own transconductance circuit, thus avoiding the use of VCAs in the signal path.
- Continuously variable control of input gain, threshold, ratio and gain
make-up
- "Fast"or "Slow" Attack modes (0.5mS or 20mS)
- "Fast" or "Slow" Release modes (40mS or 2S)
- Dual mono or stereo linked modes
- Compressor bypass switches with status LEDs
- Dual sensitivity auxiliary input (for guitar, keyboards etc)
- 8 segment LED metering to read output level or gain reduction
- Side chain insert point for frequency conscious compression
- Balanced XLR line inputs and outputs (+4dB)
- Line inputs and outputs duplicated on unbalanced connectors (-10dB)
- Program dependent attack and release time constants
- Frequency response 20Hz to 40kHz +0 / -1dB
