Thank you for purchasing this Mordaunt-Short product. The Mezzo 9
subwoofer features a new sophisticated Digital Signal Processor (DSP)
preamplifier that allows many adjustments to be made to get the best
possible performance whatever your programme choice, main speaker
system, or listening environment.
The adjustable and pre-settable level, low pass filter slopes and
continuously variable phase allow the Mezzo 9 to be matched to a wide
range of speaker systems. Twin adjustable notch/boost filters allow room
anomalies to be tuned out and a dynamics processing engine allows
either enhancement of dynamics for a more punchy movie experience or
compression/downward expansion for late night use.
A high efficiency 375 watt amplifier coupled to two 8” CPC bass drivers
allow the Mezzo 9 to recreate the bass depth required for both realistic
Music and Movie performances. Separate presets may used to allowing
you to quickly recall your own settings optimised for different listening
requirements.
Finally a combined remote control / Sound Pressure Level meter has been
designed to make setting up the Mezzo 9 simpler and more accurate.
Please do read this guide carefully, as it contains essential information in
getting the very best from your new subwoofer.
Matthew Bramble,
Mordaunt-Short Technical Director
and the Mezzo 9 design team.

1. Unpacking
Follow the diagrams to carefully unpack your subwoofer. It is quite heavy
and it is advisable to have a friend help with unpacking and moving the
unit.

2. Floor spike
Attach the feet to the Mezzo 9 as shown in the diagram. It is
recommended to use the metal spikes for carpeted flooring and the rubber feet for hard flooring or where the spikes might damage the flooring type.
Metal spikes Rubber feet
3. Positioning
See diagrams for some typical set-ups in 5.1/6.1 and 7.1 surround-sound
configurations. Your subwoofer can be placed almost anywhere in the
room as bass is much less directional than higher frequency sound.
However, due to the acoustic effects of the room, experimentation is
always recommended. In particular before setting adjustments for
room anomalies such as the Notch Filters try to achieve the best
performance by changing the position of the subwoofer first. Remember
to adjust only a little at a time and to make only one change between
listening tests.
Note: For surround-sound use always ensure the correct distances/time
delays are entered in the "Loudspeaker Set-Up" page of your home
cinema receiver (refer to your home cinema receiver manual for more
information) before making any adjustments.

Save/Recall
Press the button to recall a previously saved setting (i.e. Preset). Press and
hold down the button to save the current set-up.
Back
Press to return to a previous menu item/function.
Infra-red sensor
Receives IR commands from the supplied remote control. A clear
unobstructed line of sight between the remote control and the sensor is
required.
Clip
Flashes when the input to the subwoofer DSP circuitry starts to clip or
overdrive which will degrade the sound and more importantly could
damage the subwoofer/bass drivers. If this happens turn the volume down
on your connected receiver/ amplifier, rather than or the subwoofer itself,
this reduces the level at the subwoofer input rather than the output level.
