"<=><?=@((

Since&the&late&1970’s,&most&FM&audio&processors&have&been&“all-in-one”&units;&audio&
conditioning,&multiband&AGC,&multiband&limiting,&final&clipping,&and&stereo&(MPX)&
encoding&are&all&in&the&same&chassis.&&This&approach&offers&many&benefits&in&
convenience,&performance,&and&cost&and&has&worked&well&with&traditional&composite&
STL&systems&or&when&the&processor&can&be&placed&at&the&transmitter&site.&
&
One&important&fact&about&Omina.9sg&is&that&it&is&“processor&agnostic”&–&that&is,&it&can&
be&used&with&any&processor&from&any&manufacturer.&This&ability&allows&stations&to&
significantly&upgrade&their&processing&power&and&audio&quality&without&having&to&
invest&in&an&entirely&brand-new&processor.&Or,&you&may&simply&prefer&the&dynamics&
processing&(AGCs&and&limiters)&from&another&brand&or&model&but&still&want&to&take&
advantage&of&the&superior&composite&abilities&of&Omnia.9.&Details&about&using&
Omnia.9sg&in&such&applications&are&provided&later&in&this&manual.&&

In&many&cases,&it&is&advantageous&to&place&the&main&audio&processor&at&the&studio&
while&the&final&clipper&and&stereo&generator&operate&at&the&transmitter&such&as&when&
using&a&discrete&analog&or&digital&(AES)&STL.&&
&
If&the&STL&delivers&bit-reduced&audio&using&a&lossy&codec&to&optimize&available&
bandwidth,&overshoots&are&possible&which&result&in&lost&loudness&from&the&final&
transmitted&signal.&&&

!

In&this&case,&proper&FM&clipping&must&be&applied&after&the&coded&link&where&
advanced&stereo&generation&can&add&an&additional&dB&of&loudness&with&no&further&
audio°radation.&&
&
&

&

&

Some&FM&broadcasters&are&transmitting&the&same&audio&from&two&or&more&tower&
sites.&&In&these&cases,&one&primary&audio&processor&can&feed&a&WAN&or&satellite&
distribution&system&while&individual&Omnia.9sg’s&reside&at&each&transmission&site.&&

Transmitter&sites&are&often&remotely&located&and&sometimes&shared&among&multiple&
broadcasters.&Access&may&be&limited&and&tightly&controlled.&In&such&cases,&keeping&
the&main&processor&at&the&studio&and&installing&a&smaller&and&less&expensive&stereo&
encoder&makes&sense.&&
&

&

&
Stations&employing&main&and&backup&STL’s&for&redundancy&feeding&the&same&or&
geographically&different&transmitter&sites&can&also&benefit&from&Omnia.9sg&by&
allowing&the&use&of&a&single&processor&at&the&studio.&&

Research&has&indicated&that&ratings&encoders&and/or&ratings&enhancement&devices&

processors&including&Omnia.9&and&Omnia.11&have&special&“insert&points”&designed&
for&this&purpose,¬&all&processors&do.&Placing&the&processor&and&ratings&encoder&at&

Believe&it&or¬,&the&description&“psychoacoustically-controlled&distortion&masking&
clipper”&is&more&than&just&high&tech&marketing&speak!&It&actually&sums&up&the&
premise&of&how&Omnia.9sg’s&clipper&is&able&to&deliver&such&a&clean&sound&even&when&
pushed&for&competitive&loudness.&&
&
All&FM&processors&use&clipping&in&their&final&stage&as&a&means&of&building&loudness&
and&providing&absolute&peak&modulation&control.&The&majority&of&clipping&is&
typically&done&in&the&final&L/R&stage&with&additional&(and&optional)&clipping&being&
performed&in&the&composite&domain.&&
&
This&is&also&where&the&classic&(and&oft&dreaded)&“loud&v.&clean”&tradeoff&is&made.&
When&more&clipping&is&used&to&increase&loudness&on&the&dial,&the&clipped&peaks&fall&
back&into&the&audio&and&manifest&themselves&as&audible&distortion.&&
&
There&are&ways&to&get&around&that&problem,&but&the&come&at&a&price.&Backing&down&
the&clipper&drive&will&clean&up&the&sound,&but&then&you&lose&loudness.&You&could&
move&more&of&the&“heavy&lifting”&to&the&compressors&and&limiters,&but&that&can&result&
in&an&overly-busy,&dense&sound&that&robs&the&music&of&life&and&invites&listener&fatigue.&
Indeed,&some&processors&MUST&resort&to&building&density&in&this&way&because&their&
simple&or&outdated&clippers&must&be&protected&or&simply&aren’t&up&to&the&job.&&
&
Like&any&other&clipper,&the&one&in&Omnia.9sg&clips&peaks&and&generates&distortion&–&
but&it&can&identify&that&distortion&and&use&its&proprietary&algorithms&in&the&
composite&signal&to&mask&it,&effectively&eliminating&it&from&the&final&audio.&&&
&
As&a&result,&it&comes&closer&to&eliminating&the&“either/or”&compromise&between&
loudness&and&audio&quality&than&any&other&processor&on&the&market&today.&&&

/HLCMFDCFIHE?C(%FQAFH?E=(&QJ=KK=>(

Another&trick&Omnia.9sg&has&up&its&sleeves&is&the&way&in&which&it&allows&140%&L/R&
audio&peaks&while&maintaining&100%&total&modulation,&even&with&the&challenging&75&
microsecond&pre-emphasis&curve.&This&results&in&1dB&of&extra&loudness&without&any&
additional&processing&or&clipping&and&allows&Omnia.9sg&to&be&significantly&cleaner&
for&a&given&loudness&level,&or,&substantially&louder&for&a&given&level&of&quality&–&
especially&in&the&higher&frequencies.&&

By&using&a&built-in&software-based&FM&exciter&and&spectrum&analyzer,&Omnia.9sg&can&
analyze&and&measure&the&predicted&occupied&bandwidth&of&the&real-world&FM&signal&
and&communicate&this&information&to&the&final&clipper&so&that&bandwidth&can&be&
optimized&in&real&time.&&
&

!

13&

This&is&useful&in&situations&where&a&signal&with&wider&RF&bandwidth&and&a&receiver&
with&a&narrow&front&end&“collide”&and&result&in&increased&distortion&and&loss&of&part&
of&the&signal.&&
&
When&pushing&hard&for&loudness,&using&the&RF&Bandwidth&Controller&can&result&in&a&
slight&loudness&loss&(approximately&0.5dB)&and&some&loss&of&stereo&separation,&so&its&
use&and&the&resulting&tradeoffs&will&be&largely&market-dependent.&&
&
The&RF&Bandwidth&Controller&is&also&useful&for&correcting&anomalies&such&as&single­channel&DC&offset&or&for&optimizing&modulation&performance&per&ITU&
Recommendation&1268,&details&of&which&can&be&found&here:&&

When&creating&Omnia.9sg,&we&knew&that&having&diagnostic&and&measurement&tools&
would&be&necessary.&Audio&processing&is&largely&a&“hearing”&process&but&there&is&
much&to&be&learned&by&seeing&what&your&adjustments&are&doing&to&your&sound&as&
well.&&
&
Some&stations&still&have&an&oscilloscope&on&the&test&bench&or&a&spectrum&analyzer&at&
the&transmitter,&but&it’s¬&always&convenient&(or&possible)&to&hook&up&a&processor&
to&them&while&it’s&on&the&air.&Even&if&you&did&so,&you’re&pretty&much&limited&to&
monitoring&only&the&composite&output&of&your&own&station’s&processing.&&
&
Omnia.9sg’s&built-in&solution&means&there’s&no&extra&test&equipment&to&buy&(‘scopes&
and&analyzers&aren’t&cheap)&and&no&cables&to&hook&up.&It&also&means&you&can&visually&
monitor&the&signal&at&the&input,&the&output,&and&many&points&throughout&the&
processing&path&so&you&can&tell&what’s&happening&to&the&audio&every&step&of&the&way.&&
&
As&an&added&bonus,&Omnia.9sg’s&composite&inputs&can&be&fed&from&a&calibrated&tuner&
or&frequency-agile&mod&monitor&so&that&you&can&monitor&the&other&signals&in&your&

Chapter&2:&Quick&Start&Setup&Guide&

We’ve&prepared&this&preliminary&Quick&Start&Setup&Guide&to&get&you&and&your&new&
Omnia.9sg&up&and&running&as&quickly&as&possible.&&
&
It&is&deliberately&brief&and&does¬&provide&a&full&explanation&of&all&available&
controls&and&settings,&so&we&strongly&recommend&reading&the&complete&user&manual&
when&time&allows.&
&
Omnia.9sg&is&a&slim&1RU&design&so&it&doesn’t&take&up&much&vertical&rack&space,&but&it&
is&deep.&Accordingly,&you&may&wish&to&enlist&the&help&of&an&assistant&when&racking&it&
up&and&ensure&there’s¬hing&to&obstruct&&&it&toward&the&back&of&the&rack.&&
&
The&unit&is&fan&cooled&but&leaving&an&empty&rack&space&directly&above&and&below&it&is&
still&good&practice&for&both&Omnia.9sg&and&the&equipment&directly&above&and&below&
it.&Air&is&drawn&in&via&an&intake&near&the&front&right&side&of&the&unit&(looking&at&the&
front&panel)&and&exhausted&near&the&front&left&side,&so&ensure&there&are&no&
obstructions&around&these&areas&that&would&impede&air&flow.

Connect&AC&power&to&both&of&the&internal&power&supplies.&There&is&no&power&switch.&&
&
It&is&always&possible&for&a&power&supply&to&fail&and&so&having&redundant&supplies&
does&help&protect&you&against&losing&power&altogether&in&that&event.&In&reality,&it&is&
far&more&likely&that&the&unit&will&lose&power&because&of&an&interruption&to&the&circuit&
feeding&it.&Therefore,&good&engineering&practice&dictates&that&each&supply&should&be&
fed&from&a&different&source.&At&minimum&we&recommend&that&each&source&should&be&
a&good&quality&UPS&with&adequate&surge&protection.&In&an&ideal&world&(where&
everyone&gets&along&and&you&got&to&build&the&plant&of&your&dreams&from&scratch&with&
an&unlimited&budget)&each&would&be&fed&from&a&completely&different&circuit&for&
maximum&redundancy.&&
& &
Next,&connect&the&audio&inputs&as&appropriate&for&your&installation.&Omnia.9sg&
accepts&balanced&professional&line-level&analog&audio&via&its&Left&and&Right&Analog&
Inputs&and&AES/EBU&digital&audio&on&standard&XLR&connectors&via&its&AES&inputs.&
Two&composite&(MPX)&inputs&are&also&provided&and&can&accept&a&full&MPX&signal&
from&the&composite&output&of&another&processor.&&

&
In&the&event&of&a&power&(or&software)&failure,&Omnia.9sg&provides&a&hard&relay&
bypass.&When&the&bypass&relay&is&engaged,&MPX&Input&1&is&directly&connected&to&MPX&
Output&1&while&MPX&Input&2&is&directly&connected&to&MPX&Output&2.&&Accordingly,&it&is&
possible&to&take&the&composite&output&of&a&hot&backup&processor&or&stereo&generator&
and&feed&it&into&the&MPX&input&corresponding&to&the&employed&MPX&Output.&&
&
The&main&AES&XLR&input&can&accept&audio&with&or&without&a&clock&reference&of&
between&32kHz&and&96kHz.&If&necessary,&the&built-in&sample&rate&converter&(SRC)&on&
this&input&will&up-&or&down-convert&to&the&fixed&system&standard&of&48kHz.&&
&
A&dedicated&external&reference&input&is&provided&on&the&rear&panel&via&a&BNC&
connector&should&it&be&necessary&to&sync&to&a&clock&that&is¬&present&on&the&
incoming&AES&audio&signal,&but&this&must&be&a&48kHz&signal&as&no&SRC&is&present&on&
the&BNC&input.&An&adapter&(Pin&2&hot,&Pin&3&shield)&may&be&used&for&short&runs&
without&concern.&For&longer&runs,&a&transformer&may&be&used.&&

This&menu&contains&the&controls&primarily&responsible&for&distortion&management,&

&

• Unless&you&specifically&want&the&presence&of&intermodulation&distortion&(where&

&

• The&“Clip&bass&at”&control&is&analogous&to&the&traditional&“bass&clipper&threshold”&

control&found&in&other&processors.&The&highest&setting&of&“1”&represents&a&0dB&

values&transfer&more&of&the&bass&clipping&to&the&dedicated&bass&clipper.&Each&

reduction&of&O.1&represents&an&additional&1&dB&lowering&of&the&threshold&(0.9&=&-

1.0dB,&0.8&=&-2.0,&0.7&=&-3.0,&etc.).&&&

&

• The&“Never&allow&bass&above”&control&works&in&conjunction&with&the&“Clip&bass&

at”&control&to&create&a&window&within&which&Omnia.9sg&can&dynamically&vary&the&

actual&bass&clipper&threshold&to&help&prevent&intermod&distortion.&&

&

Specifically,&it&prevents&the&bass&peak&level&after&clipping&from&exceeding&a&

certain&setting.&&

&

Values&that&are&increasingly&lower&in&relation&to&the&setting&of&the&“Clip&bass&at”&

control&will&result&in&more&protection&against&intermod&distortion&but&at&the&risk&

cause&unpredictable&and&unusual&intermod&affects,&so&adjust&with&caution&while&
