An analogue or PCM input stream contains no information about the surround mode, therefore STEREO is selected as default, if ProLogic II is not selected under the config.ProLogic II menu.

By pushing the “SURROUND MODE” key for more than one second or “STATUS” on the remote control, information about received bitstream will be displayed, e.g. PCM. The PR350 B can receive PCM inputs with sampling rates from 32kHz up to 96kHz.

For analogue inputs going through the DSP, PCM will also be displayed because the digital data from the analogue to digital converter (A/D) is in PCM format with 96 kHz sampling rate.

For the “PURE AUDIO” input, only ANALOG is displayed, because this input bypasses the DSP circuits.

The normal display returns after 15 sec. from last push on “SURROUND MODE” or by pushing the ”>VOL” key.

5.5 Side Channels

Thule Audio offers a unique 8.1 channel extension setup for large rooms: Side channels. By blending the sound from the front speakers and the rear speakers into to new channels called SSL and SSR, it is possible to create a more continuous sound sweep for sound effects moving from one end of the room to the other.

The side speakers are simply activated in the config.extended surround menu.
