Configuring the 861

Surround Controller

Fine tuning

These tests allow you to fine-tune the phase and delay

of each speaker when used in conjunction with other

speakers on the layout.

Press > or < to move between each of the speakers

in the layout.

The first display allows you to adjust the phase.

For example: Left Phase

The next display shows the distance (or delay) for the

same speaker.

For example: Left Distance 18'0

Choose the setting that gives an even sound between

the speakers, that does not change radically as you

move your head. If the setting is incorrect the sound

will appear diffused, and change in timbre and apparent

location as you move your head.

Pay particular attention to the centre channel, as this

can have a dramatic effect on the overall sound.

As you increase the delay the speaker will appear to

move away from you.

Press > or Store to proceed to the next calibration

stage.

Speaker size

These tests allow you to determine the bass handling

capability of large analogue speakers and subwoofers.

Once set, the 861 will limit the bass level to protect the

speakers from potential damage.

In each test the display shows the speaker being tested

and the current size value chosen for the speaker. This

value will default to zero, corresponding to maximum

bass protection.

•

For example: Left Size 15

Press > or < to move between each of the speakers

under test.

Press A and V to adjust the Size value for the

speaker.

As you increase the Size value, the test signal will get

louder, since the bass protection is treating the speaker

as one capable of handling more bass.

Adjust the Size value until the speaker is just

beginning to produce distortion, indicating that it is

reaching its bass handling limit.

You have now completed the calibration of your system.

Press Off (front panel or remote) to exit from the

calibration procedure.
