The new C-1 compressor maintains its position as the most flexible, polished
sounding high end compressor on the market today. Now featuring a spectacular
raven blue 6mm CNC milled aluminium front panel, General Electric US military
specification valves, high retention gold plated ceramic valve bases and circular
back-lit VU meters, the new C-1 is even fatter sounding and more rugged than
its legendary predecessor.
All controls are continuously variable (unlike some other units with switched
parameters) and high quality onboard mic preamps allow direct-to-tape recording
of microphone sources. Stereo front panel instrument inputs mean a keyboard or
guitar can feed straight into the C-1 and down to tape with a minimum of fuss.
Whether the C-1 is tracking vocals and instruments or adding roundness and warmth
to a complete mix, it will become an indispensable part of your signal path within hours.
The C-1 features a low noise solid state preamp followed by two valve stages per channel.
The valves are General Electric ECC83/12AX7A types, run from a stabilised 250v DC power
supply. The first valve stage acts as a voltage amplifier, with the second stage forming part
of the gain control element. The gain control is performed by our own unique transconductance
stage which avoids the use of VCAs – thus improving transparency and minimising distortion,
which is virtually constant at 0.05% over the full bandwidth. The frequency response of
the C-1 is virtually flat between 20Hz and 40kHz, and measured between -3dB points,
the C-1’s bandwidth is a staggering 5Hz to 70kHz!
