3 Controls & operation
3.1 Output Trim Control
This control is used to trim the output levels when
compressing a stereo mix. Its function occurs after the
electronics and therefore reduces the maximum output
level (MOL) and noise.
The Master Phoenix is calibrated for line level
(+4dBu), so that input and output are identical when
not compressing.
The gain is calibrated to feed into 10kΩ. If it is feeding
a lower impedance, the Output Trim may need to be
adjusted to a higher level for equal in/out.
3.2 Gain Control
Factory set for 0dB gain when Output Trim is also 0dB
(see above). This will need to be set to a higher level
as compression kicks in.
3.3 Attack Control
The attack control varies the rate at which the
compressor starts to react. Attack rates of 4ms at
position 1 to 120ms at position 6 are available. Usually
set at 1 (fastest), 2 or 3.
Slow attack rates make the compressor less efficient,
but can be effective for percussive tracks.
