Cloud RL Series and RSL Series remote control plates are accessories for
a wide range of Cloud zoners, mixer-ampliers and power ampliers. They
are compatible with all current (relevant) products, and also with numerous
discontinued products.
RL plates adjust the signal level in an audio channel of a Cloud device, and thus
allow audio volume in an area to be controlled locally.
RSL plates provide the same volume control function as RL plates, but
additionally allow remote selection of music source, when used in conjunction
with Cloud devices that have multiple line inputs.
Remote plate types
Functionally, there are three models of remote plate:
• RL-1: provides remote volume control of an audio channel.
• RSL-4: provides remote volume control of an audio channel, and also
remote selection of the music source for that channel, when used with
devices having up to four line inputs.
• RSL-6: as RSL-4, but for use with devices having up to six line inputs.

Further, each model is available in three physical sizes:
UK versions:
These are available in black or white nish; the part number is sufxed
‘B’ or ‘W’ respectively. All UK versions of the plates t standard UK-style
single-gang electrical back boxes, either surface-mounting or ush-tting.
Recommended back box depth is 25 mm. Two M3.5 x 20 xing screws are
supplied with each plate.
US versions:
The RL-1A, RSL-4A and RSL-6A are electrically and functionally identical
to the UK versions, but the faceplates have different physical dimensions
(4.51” x 2.76”) which allow them to be mounted into a standard US-style back
box (with vertical orientation). Both black and white nishes are available; the
part numbers are sufxed ‘B’ and ‘W’ respectively.
‘Media’ versions:
The RL-1M, RSL-4M and RSL-6M are electrically and functionally identical
to the UK versions, but are in the form of 50 mm x 50 mm Euro-modules,
which can be tted into either UK or other European back boxes with the
appropriate mounting frame.

The Media module is secured in place by the four plastic clips; two at the top,
two at the bottom (see diagram below). Both black and white nishes are
available; the part numbers are sufxed ‘B’ and ‘W’ respectively.
NOTE: All information in this manual applies equally to all mechanical versions.

Single and multi-channel operation
RL and RSL remote plates are primarily designed to provide remote control
of a single audio channel. A single channel will often correspond to a single
zone or area of a building, and the remote plate will therefore control the
audio in that zone, but see NOTE below. Many of the products listed above
have two or more audio channels; on all such Cloud devices, provision is
made for connecting separate remote control plates to as many channels as
required. (The CX163 stereo zone mixer has a slightly different arrangement;
see Wiring details on page 13 and Wiring diagrams on page 17 and 18 for
further information.)

NOTE: It is possible to control two or more channels of a Cloud multi-
channel device “in parallel” from a single remote plate; this might be desirable
where, e.g., more than one channel of a mixer-amplier is powering speakers in
the same zone, due to room size.
An RL-1 Series plate may be wired in parallel to more than one channel of an
amplier or zoner, but note that the “law” of the control will differ from that
obeyed when it is used with a single channel. When wired to several channels
in parallel, this may produce an inconvenient “cramping” of the control’s
operation at one end of the range.
RSL-4 and RSL-6 Series remote control plates require modications for multichannel operation. This topic is NOT covered in this manual. Installers requiring
this option should download the appropriate Cloud Technical Note from
www.cloud.co.uk, and carry out the modications described before installing
the plates.

Device conguration
Most RL/RSL-compatible Cloud products will require minor conguration
changes when remote control plates are installed to ensure correct operation.
RL Series plates:
When adding RL Series remote control plates, it will generally be necessary
to disable the front panel music level control, so that volume may be adjusted
only by the plate. On most units, this is done by operating a rear panel pushbutton switch. However, on devices with multiple music sources, doing this
will also disable the front panel music source control. To maintain control
of music source from the front panel, internal jumpers must be set to the
appropriate position. The products to which this applies are those which
are also compatible with RSL plates (see Compatible Cloud products table on
page 6).
RL Series and RSL Series Installation Guide v2.0
11
RSL Series plates:
When adding RSL-4 Series or RSL-6 Series remote control plates, it will
generally be necessary to disable both the front panel music level and source
selection controls, so that full control is via the plate. On most units, this can
be done by operating a rear panel push-button switch.
IMPORTANT: With both types of plate, it is essential that installers check
the Installation Guide for the specic product to which they are connecting
the plates. This will give full details of the conguration procedure. If necessary,
Installation Guides for all products can be found at www.cloud.co.uk.
On multi-channel (or multi-zone) devices, the conguration changes necessary
for remote control are always per-channel or per-zone. Channels (or zones)
to which remote control plates are not tted will operate from the unit’s local
controls in the normal way.

Wiring details
In most cases, remote control plates connect to their host devices via
per-channel, 3-pin 5 mm-pitch screw terminal connectors on the device’s
rear panel. The only exception is the CX163, which has a 4-pin connector.
The connector will be labelled REMOTE LEVEL, REMOTE LEVEL/
SOURCE, REMOTE MUSIC CONTROL, or something similar,
depending on the device.
On all types of remote control plate, connection at the plate is via a rear 3-pin
screw-terminal connector.
RL Series plates: Connection may be via single- or twin-core screened
cable. RL Series plates can generally be connected to devices that support
remote music source selection with single-core cable, but two-core screened
cable is required when connecting to devices that do not support this.
RSL Series plates: These always require twin-core screened cable.
The use of crimp ferrule-type terminals is recommended for the cable
terminations as this will provide a much more reliable long-term connection.
Recommended maximum cable length is 100 m (328 ft.)

The wiring scheme to be adopted varies between devices. See the table below
to check which of the wiring diagrams on page 17 and 18 should be followed
to connect a particular type of plate to a specic device.

CX163 stereo control options
The CX163 is a two-zone stereo mixer and has a different remote control
connector to other Cloud units. When using RL Series remote level control
plates with a CX163, the installer has the option of using a single RL Series
plate to control both left and right channels together (i.e., stereo operation),
or of using two separate RL Series plates to control the left and right channels
independently. For stereo operation, use wiring diagram C. For separate L/R
