How are they listening?
You can use headphones to verify signals or as a rough check on VOLT’s processing. But we don’t 

recommend using phones for fine-tuning your station’s sound… In our experience, dynamics per-

ceived through headphones are different from those heard over speakers, and adjustments made 

over headphones may be too subtle for loudspeaker use. 

 

For critical adjustments, listen to VOLT through high quality monitors in a studio situation. Or though 

speakers roughly equivalent to how your listeners will be hearing the station: some processing gurus 

do their most critical tuning while sitting in their cars! Don’t rely on headphones for fine-tuning, 

unless you’re sure the listeners are using headphones as well.

Front Panel Meters

VOLT’s left-most two meters are Left and Right processor input, with LEDs stepped from -28 
to 0 dBFS. These behave like standard digital level meters. The top (red) LED lights when the 
signal reaches -0.05 dBFS or higher.
The next 11 meters read the Gain Reduction [“GR”] in each of VOLT’s AGC and Limiter 
sections, calibrated between -3 and -24 dB.  The bottom LED of each stack lights when that 
section’s Gate is activated. There are 6 AGC meters (wideband, then the five individual frequen-
cy bands), and 5 Limiter meters (one for each frequency band). 

About GR Meters
The operation of a Gain Reduction meter might seem backwards, compared to the normal meters 

on consoles and amplifiers. When an AGC or limiter’s input signal is soft, the gain control algorithm 

doesn’t need to lower the gain: only the top LED will be lit, showing 0 dB reduction. As the signal gets 

louder, more reduction is applied, so LEDs below the top one start to light up. The meter “fills down-

ward” as volume increases.  

 

These GR meters let you see how VOLT is conditioning your signal levels in real-time. The amount 

of Gain Reduction at any moment depends on your signal… as interpreted by multiple parameters 

provided by the preset, the QuickTweak controls, individual processor settings on the remote control, 

and of course the nature of Omnia’s algorithms. 

 

Experienced operators keep one eye on the GR meters and both ears on the loudspeakers while 

adjusting a station’s sound.

The right-most three meters indicate output levels for the Left and Right channels (calibrated 
from -28 to 0 dBFS), and for the composite output (calibrated 0 to 100%).
