Auto Setup - Arcam AV888 Handbook

auto Setup

Auto Speaker Setup of your loudspeakers and subwoofer
(if present) is controlled by this menu. A full description
of how Auto Speaker Setup works is given on page 37.
Remember to insert the calibration microphone into the
input on the front panel and position the microphone
AuX
at the listening position before running Auto Setup.
(or O on the remote) to
Run Auto Setup – Press
oK
start Auto Speaker Setup. The process will generate test
tones from the speakers and will typically take less than
two minutes. The test tone generator will cycle round
each speaker twice.
Accept Setup – When Auto Speaker Setup has
completed without errors you can choose to accept or
reject the settings
No: The settings are not stored in memory.
<
Yes: All the speaker settings (speakers present, type,
<
distance, level and crossover frequency) are stored
in the relevant sections of the Setup Menu and
overwrite any previous settings.
Auto Setup Progress – Gives a summary of what Auto
Speaker Setup is doing as it progresses, starting with
which speaker is being tested.
Calculating EQ: Data gathered from each of the
<
speakers is being processed.
Completed Error: A problem was detected with the
<
speaker setup. See the descriptions for each of the
individual speakers, below. Alternatively an invalid
speaker configuration was detected.

If the above speakers are correctly detected as present in
your speaker configuration, their size (Small or Large),
distance from the listening position and trim level (dB)
will be displayed. Note that size does not apply to the
subwoofer. Otherwise one of the following messages will
be displayed:
Not Present: A speaker was not detected on this
<
channel.
Clipped: The test tone detected by the microphone
<
was distorted or clipped. This could be because
you have very sensitive speakers and they are
very close to the listening position. However it is
more likely that the detected signal was corrupted
by microphone handling noise or other external
sounds. Try running Auto Speaker Setup again.
Mic too close: The speaker is too close to the listening
<
position to be able to calculate its distance. If possible,
try moving the speaker slightly further away from the
listening position and run Auto Speaker Setup again.
Crossover Freq. – The frequency at which Auto Speaker
Setup determined is the best point to filter low frequency
sounds away from Small speakers and into the subwoofer
(or Large speakers if a subwoofer is not present).
Spkr Types
Settings for the types of loudspeaker you have connected
to your AVR500, AVR600 or AV888 and power
amplifier (e.g. the Arcam P777). These settings are
applied to all audio inputs and are stored in memory
and recalled each time the unit is powered up.

Surr. Back L / R –
Here you set the type of speakers that you have
connected to your AVR500/AVR600/AV888:
Large: capable of full frequency range reproduction
<
Small: not capable of full frequency range
<
reproduction at the low frequency end
None: speaker not present in your configuration
<
Subwoofer: Set whether a subwoofer is present or not.
<
For Surr. Back L/R, the number before Large and Small
in the dropdown options list is the number of Surround
Back speakers in your configuration. If you only have
one Surround Back speaker connect it to the output.
SBl
NOTE
It is not possible to set all speakers to Small unless
there is a subwoofer in your speaker configuration.
If you do not have a subwoofer, you will be forced to
set your front speakers to Large.
Crossover Freq – This is the frequency at which
loudspeakers set as Small start to redirect bass signals to
the Subwoofer or Large speakers in your system. Small
speakers redirect bass to the subwoofer, if present. The
exception is the Centre speaker which, if Small, redirects
its bass to front left/right provided that they themselves
are Large. This is done to help keep Centre bass directly
in front of the listening position.
MCH Sub Levels – This setting controls the subwoofer
level from an externally decoded multichannel source
(DVD-A, SACD, etc). Most DVD players require a
+10dB compensation on the subwoofer channel to
maintain the correct balance with the main channels.
+10dB comp.: for normal DVD players which output
<
the analogue subwoofer channel at the low 0dBr
level. Gain compensation of +10dB is added to the
subwoofer channel of the in the AVR500,
MCh inpuT
AVR600 or AV888.
No comp.: for DVD players which output the
<
analogue subwoofer channel at the correct +10dBr
level. No subwoofer gain compensation is needed
on the subwoofer channel of the
MCh inpuT
AVR500, AVR600 or AV888.
Use Channels 6+7 for – If your main zone speaker
set up does not include Surround Back Left and Right
speakers, you can choose to use the Surround Back
amplifier channels to bi-amp the Front Left and Right
pair, or as a stereo power amplifier for Zone 2 (but note
that powered Zone 2 is not available on the AV888).
Spkr distance
Calibration settings for the distances between the
loudspeakers and the listening position.
NOTE
Speakers that are not present in your configuration
will be greyed out.
These settings are applied to all audio inputs and are
stored in memory and recalled each time the unit is
powered up.
Units – Select whether you wish to measure distances in
centimetres or inches.

As described in 'essential setup' on page 36, measure the
distance from each loudspeaker in your system to your
ear in the main listening position and enter the values.
This allows the AVR500/AVR600/AV888 to calculate the
correct relative delay for each loudspeaker.
Spkr Levels
Calibration settings for the test noise signal level
through the loudspeakers and measured at the listening
position.
NOTE
Speakers that are not present in your configuration
will be greyed out.
These settings are applied to all audio inputs and are
stored in memory and recalled each time the unit is
in the
powered up.
Use the B and C navigation buttons on the remote
control to select the relevant speaker. Press O to
enable/disable the calibration noise and the
navigation buttons to adjust the noise level from each
speaker.

As described in 'essential setup' on page 36, adjust the
