Rupert Comp 754
Rupert Comp 754 is a processor that emulates the compressor/limiter section built into numerous
classic consoles developed by Rupert Neve during the 1960s and 1970s.
It is a model that lies at the root of the bus compressors used as standard items in studios and
broadcast stations, and is noted for its smooth and natural compression sound that does not impair
the expressive power of the source. By using VCM technology, this compressor models the circuits
that make lavish use of the audio transformers and discrete class-A amps (which are the signature of
Rupert Neve). Simply applying the compressor lightly will help you obtain the rich, solid Rupert
Neve sound. Even if applied deeply, it will not produce ear-fatiguing peaks or cause the sound to
break up, allowing you to retain the natural tonality while controlling the dynamics and enhancing
the depth and power of the sound.
1
METER RESPONSE switch
Selects the meter response speed.
2
INPUT ADJUST knob
Adjusts the input gain. However, the output gain changes inversely in tandem with the level of
this knob so that the volume remains the same as the pass-through volume (the volume when
COMP IN and LIMIT IN are off). For example if INPUT ADJUST is +5 dB, the input gain is
+5 dB and the output gain is –5 dB.
INPUT ADJUST can be used in the following ways.
• If the input signal level to the effect is too low to reach the threshold, you can raise the input
gain.
• You can change the input level to the input circuit (audio transformer or class-A amp) in
order to modify the tonal character.

BLEND knob
Adjusts the dry/wet balance of the compressor/limiter.
4
METER SELECT switch
Selects the signal source of the meter as input level, output level, or gain reduction.

6
COMPRESS IN switch
Switches the compressor on/off.
7
COMPRESS THRESHOLD knob
Adjusts the threshold of the compressor.
8
COMPRESS RECOVERY knob
Adjusts the release time of the compressor. With the AUTO setting, the release time changes
automatically in the range of 50 ms to 5 sec.
9
COMPRESS RATIO knob
Adjusts the ratio of the compressor.
)
COMPRESS GAIN knob
Adjusts the makeup gain of the compressor. This applies before the limiter stage.
