Help with Omnia 9 and FM and HD blending issues

Updated 3 months ago by Bryan Jones

Scope

This document applies to Omnia 9 audio processors running in FM + HD mode and discusses issues with HD blending.

Description

A customer reports the the station runs HD, and having issues with HD Blending.  A Belar HD modulation monitor running, and using the display we were able to obtain correct alignment, however, it is still drifting, and I am unsure why this is happening.

Solution

The solution here is to run the HD off the FM processing core instead of its own. This will help to stabilize the timing.

To do this;

Turn on Output Delays
  1. Navigate to System
  2. System Configuration
  3. Processing Paths
  4. Turn on "Output Delays"
  5. Click "Apply Config"
  6. Reboot.
Set "Crossfeed" option
  1. Navigate to HD1
  2. Then Processing
  3. Then Bypass
  4. Set the "Crossfeed;" to "Use FM Audio
Turn off previously set diversity delay
  1. Go to System
  2. I/O Options
  3. Diversity Delay
  4. Turn off the diversity delay set here
Finally
  1. Go to System
  2. I/O Options
  3. Output Delay
  4. Set your diversity delay here
