The wires in the mains plug are coloured with the following code: CAUTION To reduce the risk of electric shock, do not remove the cover or back panel. BLUE = Neutral (N) BROWN = Live (L) GREEN and YELLOW = Earth (E) As the colours of the mains lead in this appliance may not correspond with the colour markings identifying the terminals in your plug, proceed as follows: The wire that is coloured BLUE must be connected to the terminal that is marked with the letter `N' or coloured black. The wire that is coloured BROWN must be connected to the terminal that is marked with the letter `L' or coloured red. [. . . ] The left or right channel for each zone) of the Controller is 125 units. The loading of speakers for one CASA Interface is as follows: 1 pair of AWM70 OR 2 pairs of AWM65 OR 2 pairs AWM650 OR 5 pairs of ACM60 OR 4 pairs ACM65 OR 4 pairs ACM80 Exceeding this loading will not make an installation unsafe but will limit the maximum volume at which loudspeakers can be played simultaneously. Permitted permutations of speakers in a single zone are as follows: Master speakers Installation exceeding maximum loading (650 units) which will not allow all speakers to play to their maximum power outputs at the same time for instance in Party Mode -- maximum volume will be down by about 4dB Zone A B C D Total Speakers Installation exceeding maximum loading (800 units) which will certainly not allow all speakers to play to their maximum power outputs at the same time Zone A B C D Total Additional speakers can be connected using RJ45 T-pieces. The total loading on a Controller should not be exceeded if simultaneous maximum volume levels are required ­ see section Loading Considerations. Additional Keypads can be used to provide additional control flexibility within larger or awkwardly shaped rooms. They can also be used as additional IR `pickup points' in installations using predominantly ACM60/65/80 speakers that do not feature IR receiver/modulators. Up to three Keypads can be used in any zone. Additional Keypads are simply connected to the empty RJ45 connector marked Next Keypad on the last (or only) Keypad in the chain (as shown in Figure 16). The Local Input module makes provision for a source to be connected locally within a zone rather than to the Controller and to be available to local speakers. This would allow, for example, an existing TV/video installation to be connected locally for replay through CASA speakers. Taking a feed from the TV fixed volume outlet would allow any connected source to be switched through the TV pre-amplifier for CASA replay, massively extending the number of connected sources. RJ45 sockets marked `R' and `L' are connected to the sockets marked Local on the right and left speakers in the zone. If the variable volume of the local input needs to be fixed this can be done as part of the Initial Set-up procedure See the sub-section Initial System Set-up-System Sources for details. This ancillary allows a zone to operate with a conventional external power amplifier and passive loud-speakers in place of CASA Active Speakers. It can be thought of as a local CASA System Pre-out socket. The Remote Output takes the place of a pair of speakers in a zone. RJ45 sockets marked `R' and `L' are connected back to the right and left sockets of one zone on the Controller. the controlling Keypad connects to the Keypad socket of the same zone on the Controller (as shown in Figure 18). Alternatively if the Remote Output is to be used in conjunction with other CASA speakers the feed from the Controller can be split using T-pieces (as shown in Figure19). The feeds from the T-piece connected to the left socket on the Controller would go to both the left speaker and socket marked `L' on the Remote Output; similarly for the right channel. in addition , the Remote Output features an IR 3. 5mm input jack that accepts IR commands from a third-party and CASA Remote unit and relays them back to the CASA Controller. [. . . ] The system disregards subsequent CD play keypresses from anywhere in the system for 5 seconds after it receives an initial CD play command from a Csource keypress. Subsequent keypresses may be interpreted as Replay commands by some CD players and this delay permits the chosen CD source to go into play without interruption. The STOP key (Remote only), o key (Zone off (short press) or All off (long press)) or another source key pressed in that zone will all be actioned within the 5 second `window'. With either one or multiple CASA Controllers in use a symbol will appear in the display to warn the user that the source selected is in use in another zone or zones. [. . . ]
