INTRODUCTION
Thank you for choosing B&W.
The CASA™ Interface is designed to be used with the range of Active CASA™ speakers and offer a high quality, permanent audio installation. B&W Loudspeakers has an outstanding reputation for quality audio products. In designing its CASA™ Interface B&W set outstanding sound quality as an overriding priority. Conventional installed speaker systems use power amplifiers to drive remote passive loudspeakers. This approach often limits the size and scope of a system and its architecture. Remote powered speakers are one obvious solution. However, the industry has avoided powered speaker systems because of the need to install both power and signal cabling to each speaker. There is an additional problem involved with powered speakers in needing to switch them on and off remotely through separate control wiring. The CASA™ Interface side-steps these issues by using Active Speakers driven by remote DC power. Output lines are driven in balanced form by the Interface. This form of working permits far longer cable runs than can generally be provided in domestic audio systems without loss of quality due to cable impedance effects or interference. 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 CASA™ 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 CASA™ 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. CASA™ & the CASA™ 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 CASA™ Interface with CASA™ speakers. If you intend to use the Interface in conjunction with the CASA™ Controller you must consult the CASA™ Installation manual packed with the CASA™ Controller. Please read this manual fully before unpacking and installing the product. It will help you to optimise its performance.
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 CASA™ 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 CASA™ Controller.
The unit is shipped with both switches off (left) and the unit set as Master and Normally on.
LOUDSPEAKERS
AWM™70
The AWM™70 is a wall-mounted 100-watt Active Speaker using a 7-inch Kevlar® bass/ midrange driver and a 1-inch aluminium dome tweeter. Two 100-watt channels of amplification are provided to power the HF and LF outputs of the active crossover. Amplifier power of this order requires substantial heatsinking which is provided both by a finned rear extrusion and the ribbed baffle itself. The crossover has a damped 2nd-order network for the bass/ midrange unit and a 3rd-order slope for the tweeter. Active equalisation is used to enhance bass output and to perform drive unit correction and phase compensation giving smooth drive unit integration and good off-axis frequency response. The crossover also features overload and DC offset protection together with a power-on mute sequence (not using relays) that ensures power-up is free from clicks and thumps. An IR receiver/ modulator is mounted in the bottom centre of the baffle. This receives IR codes from remote control handsets and transmits those codes back to the Interface by way of the power supply. An LED telltale flashes to show when an IR command has been received.
AWM™65
The AWM™65 is a wall-mounted 50-watt Active Speaker using a 6.5-inch Kevlar® bass/ midrange driver and a 1-inch aluminium dome tweeter. A high-quality passive crossover is used to integrate the mid/ bass driver and tweeter. An IR receiver/ modulator is mounted in the bottom centre of the baffle. This receives IR codes from remote control handsets and transmits those codes back to the Interface by way of the power supply. An LED telltale flashes to show when an IR command has been received.
ACM™60
The ACM ^™ 60 is a 20-watt, Active ceiling-mounted speaker using a 165 mm bass/ midrange driver with a 25 mm co-axially placed tweeter. No IR input is provided. Two RJ-45 connectors (Controller and 2nd Speaker) are provided which can be used to 'daisy chain' up to five pairs of ACM ^™ 60s. See section Loading Considerations for further details.
DISABLING IR
RECEIVER/ MODULATOR
(AWM™70/65 only)
(Figure 2)
If IR reception is a problem in a particular location it may be necessary to disable IR reception on a speaker. Locate the IR board behind the IR lens at the bottom of the rear of the baffle. To disable the IR receiver locate the jumper shown in the diagram below and remove it taking care not to damage any components.
CABLING
The CASA™ System and Interface are designed to use shielded Category 5 cable with R-45 connectors (24 or 26 AWG with certain loading/ distance considerations – 120 foot runs for the AWM™70 for instance). Twisted-pair cables comprise copper cores surrounded by an insulator twisted together to form a pair. The cable is a bundle of twisted pairs surrounded by an insulator. Unshielded twisted pair cable (UTP) is common in telephony applications but is unsuitable for use in CASA™ installations. Shielded twisted pair cable also (STP) offers better cross-talk and interference performance. The EIA/ TIA 568 Commercial Building Wiring Standard defines five categories of network cabling. CASA™ is designed for shielded Category 5 cable which is 100-ohm, four-wire twisted-pair cable (eight cores) certified to 100 Mbps (Mega bits per second) transmission rates in network installations. The cable has low capacitance and low cross-talk characteristics. Of the eight cores available six (three pairs) are dedicated to providing a low impedance supply to the speakers. The remaining two cores carry the audio signal. The high frequency IR data is 'piggy backed' on the DC power supply lines. The screen of the shielded cable makes a ninth connection. All cables and terminations must conform to specifications to eliminate cross-talk and interference problems. Old style connectors and jacks are not suitable. Additionally, twists in the cable pairs must be maintained up to the connection point. One other cable characteristic needs to be considered which relates to where the cable is installed. To comply with the National Electrical Code (NEC), all cable installed into the ceiling void (plenum space) must be in metal conduit or must meet local fire codes. Two types of insulation are used:
PVC (polyvinyl chloride) insulation for normal use and fluoropolymer (Teflon) insulation for plenumrated cable. We recommend the latter for CASA™ in-wall and ceiling installations. There are no twists in the cables which are wired straight through. The only criterion is that the pairs are adjacent, for example: Brown is alongside Brown/ White; Blue is alongside Blue/ White and Green is alongside Green/ White, etc.

LOADING CONSIDERATIONS
Interface loading is governed by the permitted number and type of speakers on any one interface. The loading of speakers for one Interface is as follows:
• 1 pair of AW M™70s
• 2 pairs of AWM™65s
- 5 pairs of ACM™60s
Exceeding this loading will not render an installation unsafe. The effect will be that all speakers cannot be played at maximum power output simultaneously.
CONNECTIONS
(Figure 4)
All connections should be made with the equipment switched off. Connect the audio source – such as a preamplifier or surround sound processor – to the RCA type phono sockets. Connect the RJ-45 terminated STP Category 5 speaker cables to the RJ-45 sockets.
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. The modulation frequency of the IR output signal will be approximately 38kHz irrespective of the modulating frequency of the original remote control.
CONNECTIONS FOR ADDING SPEAKERS
Additional Speakers
(Figure 5 & 6)
Additional speakers can be connected using RJ-45 T-pieces or to the socket marked '2nd Speaker' on the ACM™60. The total loading should not be exceeded if simultaneous maximum volume levels are required – see section Loading Considerations.
