User manual B&W CASA INTERFACE

[. . . ] 16 Damage Requiring Service ­ The appliance should be serviced by qualified personnel when: a The power-supply cord or the plug has been damaged; or b Objects have fallen, or liquid has been spilled into the appliance; or c The appliance has been exposed to rain; or d The appliance does not appear to operate n o rm a l l y, or exhibits a marked change in p e rf o rmance; or e The appliance has been dropped, or the enclosure damaged. 17 Servicing ­ The user should not attempt to service the appliance beyond that described in the operating instructions. All other servicing should be referred to qualified service personnel. Warnings: To prevent fire or shock hazard, do not expose this equipment to rain or moisture. To prevent electric shock, do not use this (polarised) power plug with an extension cord receptacle or other outlet unless the blades can be fully inserted to prevent blade exposure. [. . . ] The connection requirement is for five signals between Active Speaker and Interface, namely two power, two signal and a ground. The adoption of Category 5 shielded RJ-45 plugs and cables means the CASATM Interface relies on just one proven connector type and cabling, familiar from the computer and telecommunications industries. This neatly satisfies all requirements for reliability and ease of installation. The provision of DC power wiring to each Active Speaker gave the CASATM Interface design team an easy route down which to run data from infra red (IR) receivers in the speakers back to the central Controller. This IR data is carried at high frequencies and `piggy backs' the power supply lines, eliminating the need for separate control conductors. Third-party IR remotes send back their IR data to the central Controller through this route. CASATM & the CASATM Interface are the first domestic audio systems to exploit the audiophile quality of true, in-wall Active Speakers. This manual is designed to help you install the CASATM Interface with CASATM speakers. If you intend to use the Interface in conjunction with the CASATM Controller you must consult the CASATM Installation manual packed with the CASATM Controller. Please read this manual fully before unpacking and installing the product. B&W maintains a network of dedicated distributors who will be able to help you should you have any problems your dealer cannot resolve. We suggest you retain the packing for future use. POWER & CONTROL (Figure 1) With the power switch on the rear of the Interface in the on position, the 3. 5mm trigger socket controls the unit's power up/standby status. This socket is configured by use of rear panel DIP switch (at the top and labelled as 1). In the off (left) position the unit is normally on and a +ve voltage of 5 ­12v on the centre pin of this socket will put the unit into standby. Conversely with this switch in the on (right) position the unit is normally in standby and a +ve voltage of 5 ­ 12v on the centre pin of this socket will switch the unit on. The second lower DIP switch (labelled as 2) should be off (left) for the unit to be used without the CASATM Controller. In this (Master) mode, audio from the RCA type phono inputs is present at the RJ-45 outputs. Conversely with the switch on (right) audio from these sockets is not present at the RJ-45 outputs. This (Slave) mode is required for connection of the Interface to a CASATM Controller. The unit is shipped with both switches off (left) and the unit set as Master and Normally on. ACMTM60 The ACMTM60 is a 20-watt, Active ceilingmounted speaker using a 165 mm bass/midrange driver with a 25 mm co-axially placed tweeter. Two RJ45 connectors (Controller and 2nd Speaker) are provided which can be used to `daisy chain' up to five pairs of ACMTM60s. [. . . ] This receives IR codes from remote control handsets and transmits those codes back to the Interface by way of the power supply. AWMTM65 The AWMTM65 is a wall-mounted 50-watt Active Speaker using a 6. 5-inch Kevlar ® bass/midrange driver and a 1-inch aluminium dome tweeter. Infrared remote signals picked up by speakers connected to the Interface are present at the mono 3. 5mm jack at the rear of the Interface. This socket is designed to drive third party IR window emitters with its output of 5V. [. . . ]
