Quality modes

The Integrus system can transmit audio in four different quality modes:
N
Mono, standard quality, maximum 32 channels
N
Mono, premium quality, maximum 16 channels
N
Stereo, standard quality, maximum 16 channels
N
Stereo, premium quality, maximum 8 channels
The standard quality mode uses less bandwidth and can be used for transmitting speech. For music the premium quality mode
gives near CD quality.

Carriers and channels

The Integrus system can transmit up to 8 different carrier signals (depending on the transmitter type). Each carrier can contain
up to 4 different audio channels. The maximum number of channels per carrier is dependent on the selected quality modes.
Stereo signals use twice as much bandwidth as a mono signals, premium quality uses twice as much bandwidth as standard
quality.
Per carrier a mix of channels with different quality modes is possible, as long as the total available bandwidth is not exceeded.
