WARNING: TO REDUCE THE RISK OF FIRE OR ELECTRIC
SHOCK, DO NOT EXPOSE THIS APPARATUS TO RAIN OR
MOISTURE.
This apparatus has been designed with Class 1 construction
and must be connected to a mains socket outlet with a
protective earthing connection (the third grounding pin).
This apparatus uses a single-pole power switch. As a result it is
not isolated from AC mains power when switched off at the rear
panel. The apparatus may be isolated from mains power either
by unplugging the power connector from the rear of the unit, or
by unplugging the connector at the opposing end of the power
cord or cable from its supply outlet. As a result, either or both
of these connectors should remain accessible.

DSP320.2 DSP Loudspeaker User Guide 1
Introduction
The DSP320.2 is perfect for delivering high-quality music
discreetly in any living or cinema room, whether used in stereo
systems, full surround sound set-ups, single-loudspeaker
installations, or multi-speaker listening zones.
It features one “racetrack” oval bass driver and one 85mm
wide-range driver for full-frequency response, each driven by an
80W power amplifier, making it capable of delivering full-range
sound at in excess of 106dB at one metre, with bass extension
down to 50Hz.
Acoustics
The DSP320.2 has been designed for maximum dispersion and
wide listening area plus minimum unwanted diffraction.
Each drive unit is powered individually by a dedicated low-
distortion 80W Class-D amplifier.
L+R mode allows a single loudspeaker to be used on its
own while still reproducing all the audio present in a stereo
recording. In addition, L+R mode makes multiple DSP320.2s a
great choice for larger areas with no specific listening position.
On-board DSP
On-board DSP provides thermal and dynamic bass protection
while retaining very accurate transients, ensuring that when
the loudspeaker is played at high levels – even over prolonged
periods of time – it always delivers a clean, detailed and
accurate sound.
Enhanced Bass Alignment (EBA)
Meridian’s innovative Enhanced Bass Alignment (EBA) uses two
different technologies to time-align high, mid, and upper bass
frequencies with the low bass, resulting in audibly improved
bass transients and added life and clarity.
Enhancement technologies
Meridian’s unique suite of proprietary technologies includes
FIFO buffering, DSP upsampling, apodising filters, and MHR
(Meridian High Resolution) to get the very best performance
from all digital sources.
Construction
The DSP320.2 is designed to have an elegant profile, with only
100mm installation depth.
It is constructed from a self-contained, all-metal enclosure.
A purpose-built rough-in wall-box is available separately. The
rough-in box is first fitted to the wall, and the loudspeaker
enclosure is then bolted to the rough-in box. The loudspeaker
is supplied with a trim frame which can optionally be fitted
DSP320.2 DSP Loudspeaker User Guide
2
according to the preferred finished appearance. The rough-in
box can be adjusted for various wall materials and depths.
The rough-in box is wired to mains power and the loudspeaker
carries a captive IEC mains lead which plugs into the mains
outlet socket on the rough-in box.
The paintable, perforated steel grille supplied with the
loudspeaker can be fitted where required. The grille is held in
place by powerful rubber-coated magnets which are attached
to the aluminium extrusion that forms the front panel of the
loudspeaker enclosure.
Controlling the loudspeaker
The loudspeaker can be controlled in three ways:
In most installations, the loudspeaker will be controlled by
another Meridian product within the system.
Alternatively, the loudspeaker features an infra-red receiver
which allows it to be controlled using a Meridian System
Remote.
Thirdly, the loudspeaker can be controlled using RS232
commands.

Installing the DSP320.2 DSP Loudspeaker
The loudspeaker is designed to be fitted in a Meridian wall
box type RF300. If necessary, refer to the
RF300 Wall Box
Installation Instructions
:
https://www.meridian-audio.com/rf300-installation.pdf
Contents
Each DSP320.2 loudspeaker is supplied with the following
components:
Trim-frame.
Grille.
Fabric scrim.
3mm Allen key.
3mm hex-driver.
4 x M5 guide screws for installing into rough-in box.
2 x grille extractor keys.
1. Prepare the loudspeaker for installation
Remove the grille and scrim from the loudspeaker and put
them to one side for use later if required.
Remove the two plastic nuts and bolts used to retain the trim-
frame during shipping.
•
•
•
•
•
•
•
•
•
Remove the trim-frame.
The loudspeaker can be installed either with or without the trim-
frame according to the preferred final appearance.
Because of the weight of the loudspeaker and the method of
installation we recommend getting assistance from a second
person when installing the loudspeaker.
2. Identify the cables
If the speaker is part of a daisy-chain there will be two
SpeakerLink cables in the rough-in box. They must be
connected correctly or the system will not function.
Identify which cable is the SpeakerLink input cable and
which is the SpeakerLink output cable.
If there is only one SpeakerLink cable in the rough-in box it will
be a SpeakerLink input cable.
Identify the mains cable from the loudspeaker to the rough-in
box.

3. Install the loudspeaker
If the trim-frame is to be fitted, position
it on the back of the loudspeaker.
Set the power switch on the front of
the loudspeaker to the Off position.
Hold the loudspeaker close to the
rough-in box.
Plug the SpeakerLink input cable
into the SpeakerLink input socket
on the loudspeaker. If there is also a
SpeakerLink output cable plug it into
the SpeakerLink output socket on
the loudspeaker.
Plug the loudspeaker’s mains cable
into the mains inlet socket in the
rough-in box.
Insert the loudspeaker into the rough-
in box, taking care not to trap the
connecting cables in any way.
Fix the loudspeaker in place with the
four M5 x guide screws.
No additional fixings are required to
retain the trim-frame (if fitted).
