Adjusting the sound
To change the treble or bass
The 3100 loudspeakers provide sophisticated treble and bass controls, to allow you
to adjust the broad balance of the system to correct for the acoustics of your
listening room, or for a misbalanced recording.
The controls are more subtle than conventional tone controls, and take advantage
of digital signal processing techniques to provide a more natural adjustment of the
frequency response.
• Press
Function
< or Function > until the display shows the current treble or bass.
• Press
Function
A or Function V to change the treble or bass.
The treble control tilts the frequency of the response over the entire frequency
range to make the sound brighter or dimmer. It can be adjusted between ±10db in
0.5dB steps. Normally settings between +1.0 and -2.0 will give the most natural
results.
The bass control allows you to adjust the bass response in the room by ±5dB in 0.5dB
steps. Normally settings between +3.0 and -2.0 will give the most natural results.
To change the absolute phase
You can change the absolute phase of the signal, to compensate for signals which
are out of phase, giving an unnatural-sounding bass.
• Press
Function
> or Function < until the display shows the current phase.
• Press
Function
A or Function V to change the phase.
To change the balance or axis
The balance control of the DSP loudspeakers uses digital signal processing to
compensate for an off-centre listening position by delaying and diminishing the
sound in one speaker, thus effectively shifting the speaker’s image back.
The axis control allows you to adjust the optimum listening height of the DSP
loudspeakers, like a balance control operating in the vertical plane.
• Press
Function
< or Function > on the remote until the display shows the
current balance or axis.
• Press
Function
A or Function V to change the balance or axis.
The display shows the direction and position of the listening position.
There are 32 balance steps in each direction.
The axis can be adjusted between 3 and -2, where 0 corresponds to the axis of the
treble unit. Usually a listener will be below that position, so we recommend settings
of -1 or -2.
Display on front panel not lit
Check the following:
•
There is AC power connected to the socket
on the back of the 3100 loudspeaker.
•
The power switch on the back panel of
the 3100 loudspeaker is turned on.
If the display will still not illuminate, check any
fuses in your power supply and the fuse in the
inlet of the 3100 loudspeaker. If these are all
intact, contact your dealer.
Remote not working
Check the following:
•
The battery in the MSR+ remote.
•
See if the 3100 loudspeaker has been set
up as not controller in the Meridian
Confi guration program. Note: This may
be deliberate by your dealer.
Unit goes silent when played hard
and displays ‘Hot‘
The 3100 loudspeakers have a temperature
sensing system on board, which prevents
overheating of the electronics. The sound will
continue when the speaker has cooled.
There is radio interference
The 3100 loudspeaker is a digital audio and
computing device which has been designed to
very high standards of electromagnetic
compatibility.
If this equipment does cause or suffer from
interference to/from radio or television
reception then the following measures should
be tried:
•
Reorient the receiving aerial (or antenna)
or route the antenna cable of the receiver
as far as possible from the DSP
loudspeaker and its cabling.
•
Ensure that the receiver uses well-screened
antenna cable.
•
Relocate the receiver with respect to the
DSP loudspeaker.
•
Connect the receiver and this product to
different AC outlets.
•
If the problem persists contact your dealer.
Drive units move when the speaker is
switched on or off
This is normal as the speaker active electronics
settle.
Confi guring the 3100 loudspeaker
does not have any effect
Make sure that you are confi guring the 3100
loudspeaker used as the master digital
loudspeaker in the system. This determines the
confi guration of all digital loudspeakers in the
system.
Unit stays in standby
•
Check that it is connected correctly.
•
Turn the system on from another Meridian
product in the system.
Only the master loudspeaker plays
•
Check the S5 cables are connected
correctly.
Sound is odd or mono
•
Check that the 3100 loudspeakers are
correctly confi gured as Left and Right
respectively.
The green indicator fl ashes or stays
on
This indicates that 3100 clipping is occurring.
Brief fl ashes indicate occasional clipping which
will not be audible.
If the indicator stays on for long periods this
may indicate a fault in the confi guration of
your system, and you should contact your
Meridian dealer.
