TECHNICAL PERFORMANCE

THE INPUT STAGE
The 'front end' is an entirely new design using 5 complete stages of
amplification controlled by a single volume control. The design gives
(microphone) input headroom of more than 30dB; the input is floating
balanced and will easily accept microphone levels from -70dB up to more
than 0dB. Phantom power is provided for capacitor microphones.
- Noise performance is up to finest laboratory standards
(125.5dB below input 20Hz to 20KHz 200ohm input termination)
- The line input is designed for unbalanced circuits and will accept -30dB up
to +24dB.
The nominal operating level at the 'insert' point is -10dB. but as maximum
output at that point is +24dB the PROCHANNEL can operate with any mixer
or outboard equipment.
THE OUTPUT STAGE
An LED 'meter' shows levels immediately before the output stage. An
output volume control gives the choice of output volume levels. The two
output jack sockets are identical. Output is balanced 75 ohm with
maximum output +26dB. Noise is approx. -80dB.
THE COMPRESSOR
The built-in JOEMEEK compressor is slightly different from the big studio
unit so that it is easier to use with musical instruments. The attack is
switched 1mS and 10mS.
The release is variable from 250mS up to 3secs. There is an in/out switch
for comparisons. The compression control is rotary. The compression ratio
varies from 1.5 to 1 up to 7 to 1 depending on musical content.
THE ENHANCER
The enhancer adds harmonics to the musical signal making it richer and
more exciting. The 'drive' control takes parts of the signal and feeds them
to a separate compression processor. The compressed harmonics are
'tuned' by the 'Q' control and then mixed back into the musical signal by the
enhance control. The whole effect is highly subjective and technical
performance specifications are not helpful.
