CAM-16 / CAS-16 User Manual v1.0

General Description

 
The Cloud CAM-16 is a headphone distribution matrix 
designed to provide headphone monitoring of up to eight 

stereo sound sources at up to sixteen remote locations. The 
CAM-16 has eight stereo line inputs and a balanced ‘global’ 

input with priority. A remote music mute facility is also 

provided, that may be used to satisfy the requirements of the 

Local Fire Officer.
Up to 16 RH-8 or WP-8 remote headphone stations can be 
connected to the CAM-16. Both are fitted with a headphone 
socket, rotary source selection switch and volume control. 
The RH-8 is a small, self-contained unit intended to be 
fitted to the framework of an exercise machine or to a flat 
surface. The WP-8 is a wall-mounting panel version, and 
fits a standard single-gang electrical back box, either flush 
or surface-mounting. The WP-8 also has the provision for 
connecting loudspeakers, Each headphone station is wired to 
one output of the CAM-16 using standard CAT-5 cable and 
RJ-45 connectors.  
The CAS-16 Sub-Station provides the capacity for another 
sixteen RH-8 or WP-8 headphone stations. The CAM-16 
can drive up to 15 CAS-16 units, allowing a maximum of 
256 outputs. The CAM-16 and the sub-stations are ‘daisy-

chained’ together, a multi-core cable being supplied with 

each unit for this purpose.
The only front panel control on either unit is the power 

switch. All input and output connectivity and gain controls 
are on the rear panels. The units are intended to be rack-

mounted in a protected area, with only the headphone 

stations available to the users.

This manual describes the installation, wiring and set-up 
procedures for the CAM-16 Audio Distribution Matrix and 

the CAS-16 Sub-Station. Both the CAM-16 and CAS-16 

require RH-8 and/or WP-8 headphone stations to realise 

a functional system; installation instructions for these are 

included with each headphone station.
