Coded Audio Considerations; Studio Pro Style; Purpose; Delay Throughput - Omnia ONE Installation And Operation Manual

Just as in the section on 'overdoing' processing, again moderation is the key. If all of the above changes are made in
unison there is a possibility of severe low frequency buildup. This would unbalance the audio spectrum and produce
the illusion of "lost" presence and high frequencies.
Generally, an increase in the Bass boost alone will provide a sufficient enhancement to the low end. Bass
adjustments should typically be done after selecting the preset you wish to use and the low pass filter that is
appropriate for the codec to be used.

Coded Audio Considerations

Adjusting processing for coded audio is different than conventional radio. While many of the dynamics functions are
the same, i.e. compression, limiting, EQ, etc, please consider that the audio processor is a tool to improve the
performance of the codec. This is especially true at lower bitrates. When making processing adjustments, try to
avoid building too much density in the presence and high frequency ranges. Density in this spectra cause codec
efficiency to become reduced and artifacts increased.
Even though Sensus technology is applied downstream from the main processing and will improve system
performance, remember that the processor is a sum of its collective dynamics parts and the result will be based on
the cumulative effect of all of the settings. When adjustments are being made pay particular attention to program
content that segues from music to voice and back again. If everything is working properly the vocal quality should
not change due to the coding process. If this is noticed, try reducing the Sensus function value by one adjustment
click and then re-evaluate.

Studio Pro Style

Welcome to the OMNIA.ONE Studio Pro!

Purpose

The Omnia.ONE Studio Pro was created for use in studio applications that do not require low-pass (high-cut)
filtering or pre-emphasis, do not necessarily require precisely controlled peak output levels but may require
minimizing the time delay through the unit (delay throughput).
The Omnia.ONE Studio Pro is best suited for audio applications that require processing to control overall levels
with minimum delay throughput, minimum processing artifacts, minimum distortion and maximum fidelity.
Some examples of such applications would be headphone feeds, pre-delay feeds, TV/video studio/remote pre-
processing etc. The Omnia.ONE Studio Pro is ideal wherever full-fidelity multi-band processing is needed along
with minimum delay.

Delay Throughput

The two sections of the processing that cause the most delay are the "Bass Boost" enhancers (2.1 ms) and the Final
Limiter (2.7 ms). These sections can both be bypassed, if desired, to minimize the delay time of the audio through
the unit.
With both of these sections bypassed, the delay through the unit will be only about 2.8 ms when using the digital
AES/EBU input & output. There is an additional delay of about 1.5 ms when using the analog inputs & outputs (for
a total of about 4.3 ms) due to the delay through the A to D and D to A converters.
With both of these sections engaged the delay through the unit will be about 7.6 ms using the digital I/O and 9.1 ms
using the analog I/O.
