EDITING LIMITERS

Parameters of the Limiter

The parameters included on the DDP for limiting operations are as follows:

Off/on: Again, the limiter must be turned on to be able to change the parameters and affect the signal. The curve

window shows the threshold point of the limiter.

Threshold control from -60dB to +4dB: As you move the threshold of the limiter up and down, you see the

output level of the DDP move in relation to the setting. This means that the limiter of the DDP sets the

absolute output level for the unit. Remember that very fast transient signals can occasionally “sneak” past the

threshold control of any limiter. If you wish catch every single transient, set the TCM to a longer delay time,

allowing the DDP to begin to react to a transient signal faster. (For complete information on the TCM™ Transient

Capture Mode controls, refer to the gate section on page 14 and 15, as well as appendix #1) Also note that the

digital meters show when even 1 sample gets through the threshold. this can be disconcerting, given the fact that

it appears that much more signal actually gets through the threshold. Also, it is possible to set the threshold of the

limiter below the threshold of the compressor, causing all of the gain reduction to happen in the limiter, and none

to happen in the compressor. As you do this, you will notice that the curve window displays exactly what the

threshold level is set to, even to the point of “overwriting” the compression settings. Move the threshold level of

the limiter up and down to see how this effects the composite signal. Limiting takes place after the compressor’s

gain control setting

Attack control from 0.1ms to 200ms: The attack control sets the speed at which the signal is limited as it cross-

es over the threshold into the limiting region.

Release from 360dB/sec to 5dB/sec: The release control sets the speed of release of the signal as it goes below

the threshold, out of the limiting region, and is returned to its normal, unprocessed waveform.
