2. Speaker setup

The following two sections can be performed by Cambridge Audio CAMCAS
recommended that you do read these sections to understand the reasons for
these settings and their implications.

Speaker Delay

Because the speakers in a surround sound system are usually different
distances from the listener the 351R incorporates the ability to apply a
variable digital delay to each of the channels so that the sound from each
arrives at the same time at the listening position for best surround-sound
effect.

To set the delay times automatically, refer to the "Auto setup" section of this
manual.
To set the delay times manually, simply measure the distances from the
listening position to each speaker as shown in the following diagram:
No delay setting for the subwoofer is necessary.
Set the distances in the OSD Speaker Distance menu to the nearest value
of distance set.
Go to the 'Speaker Distance' and highlight each speaker in turn. Set the
distance to the nearest value to that which you measured by using the Left

Level calibration

The 351R allows level calibration to match the acoustic level between
different types/sizes or even manufacturers of speaker that may be being
speaker. This can be done manually through the 'Level Calibration' menu in
the OSD or automatically, see the following Auto setup section of this manual.
Sound Pressure Level (SPL) meter (more accurate and recommended but not
essential) the level of sound produced by each speaker and set relative levels
for each speaker so that they all sound the same loudness at the normal
listening position. The 351R incorporates a Test Signal Generator (broad-
band white noise) to facilitate this.
Press the button on the remote control to turn on the OSD then select the
'Speaker Level' menu. Now turn on the test signal by highlighting this item
and pressing the Left or Right arrows:

move to that channel. Compare the loudness of all channels as heard at the
listening position.
A "rushing" or "hissy" sound should be heard.
only, channels of different frequency responses can sound different in terms
of the "tone" of the sound i.e. more or less hissy).
Pick the channel that sounds most different and select it to listen to the
the remote) and continue comparing it to other channels until it is of equal
the same in terms of loudness, press the OSD button again to save the

CAMCAS Auto speaker setup for Distance/Level

The 351R includes our simple automatic speaker setup system called
'CAMCAS' (Cambridge Audio Mic Controlled Auto Setup). The system performs

Before activating this feature the 'Decode Mode' (i.e. type of speaker package
e.g. 5.1) and Large/Small/None status of each speaker must be set correctly
as per section 1. This is important as the unit will only look for and check the
speakers you have told it you have.
