VOLT PROCESSING
VOLT Processing Terminology
Most of VOLT’s controls are labeled with standard studio or processing definitions, and should
be intuitive to any engineer. But a few names are our own invention… because they’re con-
trolling algorithms of our own invention. Here’s a glossary of those terms.
Some of these functions aren’t needed by every DSP|Core application, and don’t appear until
you’ve activated the relevant firmware. So you won’t see a Space-EFX control, for example, if
your VOLT is set up for AM broadcasting.
Outputs
Narrow/Wide LPF Frequency [AM Only]: There are two different tunable low-pass filters
available in VOLT: AM, optimized for different applications. The preset determines which one
will be active, and you can control its cutoff frequency. The inactive one is grayed out.
Tilt Eq and Frequency [AM Only]: This is very-low-frequency equalization (between 5 – 55
Hz), designed to compensate for “droop” when square waves are broadcast through older
plate-modulated AM transmitters. You may find it helpful with a few program formats, depend-
ing on the equipment you use.
Composite Separation [FM Only]: Switchable between Stereo, Mono, or a -3 dB or -6 dB blend.
This can be helpful in controlling multipath issues.
QuickTweak
Density: Controls relative drive into the limiter bands, while ratios and time constants are
program-dependent.
Lows: Affects both the amount and shape of processing for the two bottom bands.
Highs: Amount and shape of processing for the two top bands.
