Omnia-6ex Use and Operation Manual – V: 1.20

Note 2: The headphone output is automatically appropriately de-emphasized when any value of pre-emphasis is

being used.

ITU BS-412 Power Limiting

In certain parts of the world, the average multiplex signal power must be controlled to reduce adjacent channel

interference. The currently enforced standard falls under the ITU BS-412 regulations. The Omnia-6EX has a very

effective Multiplex Power Limiter that may be enabled to comply with these regulations.

The Power Limiter control sets the average multiplex power from 0.0dB up to 9.0dB (in 0.25dB steps) above the

original 0.0dB ITU BS-412 standard. The default setting is Off.

Effectiveness of the Omnia’s ITU BS-412 Power Limiter

Loudness Loss Warning!

If your country's regulatory agency does not require the use of the ITU BS-412 Multiplex Power Limiter, make

certain that the BS-412 Power Limiter is set to off, or severe loss of loudness will result! For example, when the ITU

BS-412 Power Limiter is switched on and set at 0.0dB, there is approximately a FIVE dB loudness loss over the

limiter being switched off!
