8 44/50: Installation and Operation Manual
24 Music signal processing PCB
When no remote control PCB (REM-4) is fitted, four circuit jumpers are fitted to the
connector CON7; these jumpers must be removed before fitting the REM-4 module.
If you wish to disable the music signals in any of the four zones, remove the relevant
jumper from the connector CON7.
25 Installing RSL-1 or RL-1 Remote Controls
The remote control plates, RSL-1 and RL-1 are compatible with UK domestic electrical
accessories and can be mounted onto a standard British flush or surface mounted 25mm
deep back box. Two-core cable with overall screen should be used to connect the remote
controls to the module mounted inside the Cloud 44/50. The circuitry uses the industry
standard ‘Thats 2150A’ VCA chip to provide very low noise and distortion together with up
to 90dB of attenuation.
26 Controlling two or more zones with one RL-1
A single RL-1 can be used to control the music level of more than one zone, however, the
extra load can cause the control to operate unevenly throughout its range; this has
proved to be of little consequence operationally.
When the RL-1 is used with the 44/50, wire it with single-core screened cable. It is
assumed that the front panel music source select control will operate normally and the
jumpers J1, J2, J3 & J4 will be configured for front panel (FR) control. Diagram on
following page.
