Auto speaker setup
ere is a proprietary automatic loudspeaker setup
function built into your AVR500, AVR600 or AV888.
e Arcam Auto Speaker Setup function attempts to set
all the essential speaker settings for all the speakers in
your system. It also calculates room equalisation (Room
EQ) lter values to remove some of the worst eects of
resonant frequencies in the listening room.
Your AVR500/AVR600/AV888 package is supplied with
a calibration microphone, which should be inserted into
AUX jack socket on the front panel and positioned at
the main listening position. is microphone picks up
the special calibration tones generated by the speakers
when Auto Speaker Setup is run. e AVR500/AVR600/
AV888 then analyses the signal and computes:
which speakers are present,
crossover frequency to the subwoofer (or large front
speakers if no subwoofer is present),
problem resonant frequencies in the room which
need control by ltering.
It also warns if any of the speakers are too close to the
microphone or if the measured tone is clipped.
To help the system be as accurate as possible when
performing Auto Speaker Setup, there are a few
guidance rules that should be followed:
Minimise any background sounds in the listening
room and other nearby rooms.
Close all windows and doors in the listening room.
Turn o all fans including air-conditioning systems.
If holding the microphone in the hand rather than
mounting on a tripod or similar, keep your hand and
ngers still to avoid generating ‘handling noise’.
Position the set up microphone pointing upwards at
roughly head height in the normal listening position.
It is not necessary to point the microphone directly
at the speaker generating the test tone. (It helps if
you are able to position the microphone exactly
where your head would normally be for listening,
with the microphone in direct unobstructed view of
If your system includes an active subwoofer, start
by setting its output level / gain control to a value
halfway between maximum and minimum.
When activated, a calibration tone is played through
each channel in turn, including the subwoofer channel.
e calibration tone cycles round each of the speakers
twice. If you do not have a full 7.1 speaker conguration
there will be periods of silence between some speaker
channels. Follow the ‘progress’ information on-screen.
Aer all the channels have been measured, a summary
of the speaker conguration will be displayed on-screen.
You can then choose to accept the settings, re-measure
your system again or cancel Auto Speaker Setup without
storing the settings.
e Auto Speaker Setup function is found within the
Setup menus, see page 37. By default, Room EQ is not
applied to any of the source inputs. You should enable
Room EQ on inputs you think benet from this feature,
as required, by listening when playing typical source
material through each input. is is enabled from within
the Input Cong menu.
While room equalisation can help to reduce problems
with listening room acoustics, it is usually far better
to try to solve these problems with the room directly.
Proper loudspeaker positioning, acoustic wall
treatments and moving the listening position away from
walls should produce far better results overall. However
it may be dicult to do this in a home environment, so
Room EQ is your next best choice.
We advise you to look over the reported measurements
on the screen following Auto Speaker Setup for any
obviously incorrect results, in particular to ensure the
reported speakers match your conguration and that the
speaker distances to the listening position appear look
roughly correct. If the results are not what you expected
re-run Auto Speaker Setup.
e Auto Speaker Setup function is normally quite
accurate but occasionally false results can be generated.
Problems may be as a result of:
external sounds or rumbling / handling noises
picked up by the microphone
sound reections o hard surfaces (e.g. windows or
walls) close to the listening position,
very strong acoustic resonances within the room.
If you are still experiencing diculties or you wish to
have the most accurate results for ultimate surround
performance, we recommend using the manual method
of establishing speaker distances and levels.
Using a subwoofer
If your system includes an active subwoofer you may
need to re-run Auto Speaker Setup with the subwoofer
output level / gain control set to a higher or lower value,
if the summary screen reports problems setting the
Auto Speaker Setup will attempt to choose a crossover
frequency that allows the smoothest low frequency
transition from the main speakers to the subwoofer.
However if this does not produce pleasing results we
recommend manually trying other crossover frequencies
to nd something more to your preference.
See the next sections for information of how to enter or
change speaker settings manually.
