Using the DSP loudspeakers as a control unit
In systems with a Meridian preamplifi er or control unit all of the functions of the
DSP loudspeakers, including volume, treble, and bass, are operated via the
controller. For more information refer to the user guide for the preamplifi er or
control unit, and you can ignore this chapter.
The DSP loudspeakers can also be connected directly to up to two digital sources to
create a complete, minimum system. This chapter provides step-by-step instructions
for operating the DSP loudspeakers in a system with no Meridian preamplifi er or
control unit.
Switching on and selecting a source
When not playing, the DSP loudspeakers should be left in the standby state. This
uses a negligible amount of electricity, but ensures that the components of the
loudspeakers operate at maximum effi ciency from the moment you start.
If you are not going to use the DSP loudspeakers for several days you should switch
each unit completely off at the back panel, and disconnect it from the AC power
supply.
To select a source
• Press the appropriate source key on the remote; eg
Radio
.
This will bring the DSP loudspeakers out of standby, and the displays will show the
currently selected source and volume setting.
For example:
Radio 65
By default the 12 sources are available.
As standard, all the sources are set to select the D1 digital input.
To switch to standby
• Press
Off
on the remote.
The loudspeakers will switch to standby
and the displays will show:

Changing the display
The DSP loudspeakers display information about the current settings on the 8-
character front-panel display.
In addition, three coloured indicators show status information.
To change the displayed information

steps between the options: Source and volume, Meridian source
display (dashes if not present), Audio format, and Blank.
The audio format display shows PCM, Data, or MHR followed by the frequency, or
NL (not locked).
Status indicators
The display includes the following status indicators: Red: Master loudspeaker,
Yellow: 88kHz or 96kHz input, and Green: Clipping.
Adjusting the volume
To change the volume
The DSP loudspeakers adjust the volume in precise steps of 1dB, where 9dB is
equivalent to doubling the loudness, and can be varied in the range 1 to 99dB.
When you fi rst connect power to the DSP loudspeakers the volume is set to 65,
which is similar to the midway position of the rotary volume control on a
conventional preamplifi er.
• Press the red
A
or
V
keys on the remote.
As you adjust the volume setting the display will show
the current volume level. For example:
Radio 55
To silence or restore the sound
• Press
Mute
on the remote. The display will show:
