OPTIONS AND ADDITIONAL INFORMATION
RL-1 Series and RSL-6 Series remote control plates – general considerations
Cloud RL-1 Series and RSL-6 Series remote control plates are available in three form factors: two fit single-gang UK or American
electrical back boxes respectively, while the third is a 50 x 50 mm “Media” module, suitable for “Euro-module” mounting frames
available in most European countries. Back boxes of either the recessed type or surface-mounting type may be used, providing
they are at least 25 mm deep.
Each plate should be connected to the rear panel
RSL-6
port using single- or twin-core screened cable as described at “Music
Control” on page 12. The plate terminations are conventional screw terminals and the
RSL-6
port on the mixer is a 3-pin
5 mm-pitch screw terminal connector.
The remote control plates are passive and thus do not draw any significant current from the mixer.
Control of music source and level via external DC
It may be necessary in some installations to adjust the music level and select music source from an external control system
(e.g., Crestron, AMX, etc.). If the RSL-6 port is not required for an RL-1 or RSL-6 Series remote control plate, it may be used
to receive DC voltages from the external system to effect these adjustments.
Both music source selection and level can be controlled over their full ranges with a DC voltage of 0 to +10 V. The pinout of
the
RSL-6
port is as follows:

NOTE: If the control voltage source is not isolated from the power earth, there is a small risk of creating a ‘ground loop’ by
linking the mixer technical ground (0 V) to the ground (0 V) of the equipment supplying the control voltages. To minimise this
risk, we suggest that all pieces of equipment be in close proximity, and supplied from the same power outlet.
