3. Compressor/

Limiter: Dynamics

Processing

The final stage of processing is the

opto/tube-compressor/limiter. When properly

adjusted, it will ensure that the signal will not be

overdriven into clipping in the analog realm nor

(with the DI-Mod option) the digital realm.

By compressing the dynamic range of the input

signal, it maintains the output signal at a higher

average volume level.

3.1 Limit Point

and Compression

This multi-functional control affects both the

intensity of the compression and the location

of the limiting point (Threshold). It is divided

into the two control regions, LIMIT@

and COMPRESSION.

Operation:

ON: activates the dynamics processing.

LIMIT@: from moderate thickening of the signal

when turned completely counterclockwise, to

full-scale limiting at 0 dB, and substantial

tightening up of the signal in the range

in between.

COMPRESSION: from the middle position and

beyond, softer signals are increasingly made

louder, to maximum compression in the full

clockwise position.

Note: Setting the Input Gain control

too high can lead to audible distortion

in spite of limiting. Take care when

adjusting input levels that the level

remains in the green!

3.2 Gain-Reduction

This display shows the instensity of the

compression. The reduction of the level

is shown in dB from -1 to -22.

INFO

The compressor/limiter control, though simple to use,

is remarkably effective. When turned completely

counterclockwise, there is a mild compression of the

strongest signal peaks. The more this control is

turned clockwise, the lower the threshold is set. In the

control's middle position, "Limit @ 0dBfs," the

channel is dependably protected from being

overdriven. All signals are limited full-scale at 0 dB,

a requirement for digital recording. At the same time

with this setting, soft signals are amplified

considerably. The more you turn the control

clockwise, the amplification is greater, while the

limiting function stays the same.

QUESTION: With hard limiting at 0 dB full-scale, is

the sound similar to that of a brick-wall limiter?

ANSWER: No, not at all. The limiter in the DTC™

doesn't slam the signal against the wall, on the

contrary. The compressor function turns into a

limiting function very gradually, i.e. soft-knee. The

sound that results is comparable to that of large-head

analog tape machines. Thanks to the added

overtones, compressed signals are more perceptible

to the human ear, so they are experienced as if they

were louder than they actually are.

INFO

Although the compressor does react very kindly to

signals thrown at it, one should not overdo it. With

very dynamic sources like vocals or funk bass, short

peaks are normal. If the display is “stuck” on

maximum, the compression should ordinarily be

reduced. On the other hand just such a high amount

of compression may be desirable as a special effect.

Let your ears decide.
