Arcam AVR200 manual Channel balance, Channel delays

DIMENSION (Dolby Pro Logic II Music Mode only) Allows the gradual adjustment of the soundfield either towards the front or the rear. This can help achieve the desired balance from all the speakers with certain recordings that may contain either too much or too little spatial effect. Step ‘0’ is the recommended setting, which has no effect on the sound. Steps ‘+1’, ‘+2’ and ‘+3’ gradually move the sound forward, and steps ‘–1’, ‘–2’ and ‘–3’ move the sound towards the surrounds.

Channel balance page

From the Channel balance page, you can trim the level of each individual loudspeaker connected to the AVR200. Due to the different performance characteristics or positioning of each loudspeaker they may need to be set to different levels to provide a balanced sound from the listening position. To help set this balance, the AVR200 can generate a test tone that plays an identical signal through each channel in turn. Trim the balance of each speaker in turn until they all appear to produce the same volume.

Once the channel balance page is shown in the OSD, press the TEST button on the remote control to start the test tone. Make sure that either Dolby Digital, Dolby Pro Logic or Dolby Pro Logic II is selected, and that the volume on the AVR200 is set sufficiently high for the tone to be heard. The test tone automatically cycles through each speaker channel until the TEST button is pressed a second time.

Each loudspeaker can be trimmed between +10dB and –10dB.

You can return to the Channel balance page at any time (without first entering the OSD) by pressing the TEST button on the remote control. Press TEST again to exit this page.

NOTE: The test tone generates a noise which may not be heard through a subwoofer. To set your sub to a suitable level, turn off the test tone and experiment with the trim while playing a piece of music or a movie you are familiar with. There is no right or wrong level for the sub: simply find the balance that is best for you.

Channel delays page

For best results in a surround sound system, the sound from all loudspeakers should reach the listener at the same time. To help achieve this the AVR200 can add slight delays to certain channels when in Dolby Digital or Dolby Pro Logic modes.

When playing a Dolby Digital source you can set a delay for the centre channel of between 0 and 5ms and a delay for the rear channels of between 0 and 15ms.
