Each AERO includes the same set of factory processing presets to get you started. You can access a preset using the NfRemote interface. For AERO hardware units that include a front panel display, you can also use the unit’s front panel controls.
All presets are adjusted so that with the input content averaging around -24 LKFS, the output is optimized to produce -24 LKFS, ± 1–2 dB per ATSC A/85.
Compliance with stricter EBU loudness regulations can be achieved by using the advanced ITU (AI) limiter (software v0.13.55 and later).
Note: This calibrated measurement is made with a Linear Acoustic LQ-1000 or LQ-1, with 10 second integration. Longer integration times produce measurements with less variation.
Some presets do not use every parameter. For example, TV 4B Gen does not use the 5th band.
Use the Diff Presets control to show the difference between two presets.
Loading a Preset
To load a processing preset using NfRemote:
In NfRemote, choose an Instance, an UPMAX upmixer or DRC loudness control processor and then Load Preset.
For example, choose Instance (1 or 2) > UPMAX II Program I > Load Preset or Instance (1 or 2) > DRC Program I > Load Preset.Perform one of these steps:
In the Load panel (the bottom right side of the NfRemote window), double-click an available preset.
To load a preset from your computer, click the Load From… panel, locate the preset in the navigator window, highlight the preset, and then click Open.
Click the Recall Backup panel to recall the previously loaded preset.
Note: After a preset is loaded, it displays in the Current Preset panel. The previous current preset moves to the Recall Backup panel.
Saving a Preset
To save a preset:
Adjust the current preset as desired.
Choose an Instance, an UPMAX upmixer or DRC loudness control processor and then Save Preset.
In the field that displays the current name, type in a new name.
Perform one of these steps:
To save the preset in AERO.enterprise, click the Save Preset button.
To save the preset to your PC (for example, to share it to another computer), click Save to PC…, and then choose a location on your computer.
Deleting a Preset
To delete a preset:
Choose an Instance, an UPMAX upmixer or DRC loudness control processor and then Delete Preset.
When prompted, click Yes to delete the preset.
Tip! If you mistakenly delete a preset, you can immediately retrieve it by clicking Recall Backup, and then saving the preset.
Diff Preset
This feature highlights parameter settings that are different between the current and previous preset. When values differ, the setting names and values display in yellow, instead of the default white. When settings match, they display in white. This provides a way to return to a setting after making changes.
Example: To enable and use the Diff feature to see the differences between two presets:
Load an UPMAX upmixer or DRC loudness control processor preset.
Make adjustments to the preset and then save the preset.
For example, choose Adjust for the Instance and program, change some settings, and then save the preset.Choose Load Preset for the Instance and program to access the Diff Preset button.
In the Load Preset panel, the updated preset displays as the Current Preset. The original preset displays as the Recall Backup preset.
Click the Diff Preset button.
To note that the Diff feature is enabled, an (M) modified flag displays after the current preset’s name.
When you return to the current preset’s parameter pages, settings that are different from the Recall Backup preset will display in yellow.
Navigate to where you made changes previously (for example, in the Adjust panel for the current preset instance and program.
Change a setting that is in yellow and notice that it turns white when you reach its original value (which is the value for the Recall Backup preset.
Factory Processing Presets
This section lists AERO factory processing presets as they appear in the NfRemote interface for all units, or on the front panel of units that have a display.
There are different presets for an UPMAX up mixer and DRC loudness controller processor.
UPMAX Upmixer Presets
Full Center (No Center in L-R)
This preset provides the same signal to both the left and right channel.
Reference Settings
This preset offers standard processing test settings that match TV 5B Gen.
Upmix Center Diverged
With this preset, the center is spread slightly to the left and right channels, such that the audio is not fully diverged.
Upmix Center Diverged with dialogue +1dB
This preset is the same as the Upmix Center Diverged preset – the center channel spread slightly to the left and right channels – with the addition of 1 dB added to the center channel (for dialogue).
DRC Loudness Controller Processor Presets
Fine Arts 5B Gen
Fine Arts 5-Band General offers medium processing appropriate for artistic programming that may have large dynamic range variations. It produces consistent loudness and spectral balance.
ITU 5B Loudness Lim
ITU 5-Band Loudness Limit utilizes a specially tuned Multiband AGC Limiter and the Final Limiter to slowly adjust the average program loudness to a specific loudness value as measured over time. The Multiband Limiters and Final Limiters act until the very slowly responding wideband AGC catches up.
The multiband AGC is bypassed (1:1) so spectral balance is unaffected. This preset can be appropriate for ingest, live, or network transmission applications where content is pre-normalized.
Music 5B Hvy
Music 5-Band Heavy is an aggressive preset for TV music channels that effectively deliver music programming to small televisions and portable receivers.
MVPD 5B Gen
MVPD 5B Gen is intended for Multiple Video Program Distributors who may not have full control of all programs, interstitials, or commercials present in a given network stream. It applies medium-light multiband processing, sets Gate and Freeze to prevent background noise pull-up, and is tuned for all genres.
Net 5B Limit
Net 5B Limit applies a final polish to an already consistent network program prior to distribution. A combination of TV 5B Light and ITU 5B Loudness Limit, this preset has a very slow input AGC, and a lighter multiband AGC. It preserves microdynamics and pulls the low-level information up slightly while protecting against long-term loudness shifts.
Protection Limit
Protection Limit sets all processing to unity gain and leaves only look-ahead peak limiters in the signal path. The master output level is set to 0 dB, so applied signals get a unity gain path through the processor.
Reference Settings
This preset offers standard processing test settings that match TV 5B Gen.
Sports 5B Gen
Sports 5-Band General provides medium processing that features quick response with minimal background pumping. It keeps dialogue present and audible, even in rich surround mixes.
TV 4B Gen
Television 4-Band General is essentially the same as TV 5B Gen with four audio bands. This keeps all other settings the same, lessens the density and impact on dialogue, and results in more open sounding audio, albeit with less short-term dynamic loudness control.
TV 5B Gen (Default)
Television 5-Band General is the factory default preset and also the most commonly used. It provides moderate dynamic range processing and is appropriate for all content types.
TV 5B Hvy
Although Television 5-Band Heavy is similar to TV 5B Gen, its multiband compression ratio is higher, which creates a denser but less dynamic sound useful for systems with smaller speakers.
TV 5B Light
Although Television 5-Band Light is similar to TV 5B Gen, its multiband compression ratio is lower (2:1) for more subtle action. This is an excellent preset for content known to be consistent that needs just a bit of spectral polish.
Note: This preset allows more variations without correction. For already consistent content, this is not an issue.
TV 5B Loud
Television 5-Band Loud is similar to TV 5B Hvy, but louder and punchier.
