Applications
To connect a pair of DSP320 loudspeakers to
a Meridian Audio Core 200
The DSP320 loudspeakers are ideal for a compact Audio Core
200 based home entertainment system.
Connect analogue and digital sources, such as a TV and
satellite receiver, to the appropriate inputs on the AC200.
Connect the lower SpeakerLink output on the AC200 to the
Master DSP320, using an RJ45 cable.
•
•
Connect the upper SpeakerLink output on the AC200 to the
Slave DSP320, using an RJ45 cable.
Make sure the Channel selector is set to the Left position on
the front of the left loudspeaker and to the Right position on
the front of the right loudspeaker.

To use DSP320 loudspeakers in a Meridian
Digital Theatre
DSP320 loudspeakers are ideal as the rear loudspeakers in
a Meridian Digital Theatre, in conjunction with DSP520 (or
DSP640) loudspeakers as the front main and centre speakers.
An ideal source is the Meridian G65 Digital Surround Controller.
The following diagram shows how to connect the loudspeakers
using “home run” wiring.
Connect the L+R SpeakerLink output on the lower row of
the G65 to the Master digital loudspeaker (here the front left
loudspeaker), using an RJ45 cable.
•
Connect the appropriate SpeakerLink outputs on the G65 to
each of the remaining loudspeakers, using RJ45 cables.
Make sure the Channel selector on each loudspeaker is set
to the Left, Right, or Centre position as appropriate.
Alternatively you can connect the loudspeakers using “daisy
chain” wiring: connect the front and rear L loudspeakers to
the G65, and then link each pair of loudspeakers together by
connecting the output from the L loudspeaker to the input of
the R loudspeaker.

The DSP320 is an ideal loudspeaker for use in a multiroom system. The signal to each room can be provided by a
Distributor 3, with independent control over the volume of each
pair of speakers via the control system.
Where only monophonic sound is required, such as in a hallway
or dressing room, one Distributor 3 can be used to control two
DSP320 loudspeakers switched to Mono mode.
An ideal source for the system is a Meridian Media Source 200.
Connect the SpeakerLink output from the Media Source 200
to the SpeakerLink input of the first Distributor 3 module.
Connect the digital output from the first Distributor 3 module
to the digital coax input of the second Distributor 3 module.
Connect the Meridian DSP loudspeakers to the SpeakerLink
outputs of each module.
Connect the RS232 control connector from each module to
the control system.
Information and set-up software for installing Meridian systems
can be found on the Meridian website:
