Introduction
The BT-1 is a wireless remote audio input module for use with all Cloud products tted with an RJ45 Facility Port or an RJ45
Extension Port.
The BT-1 enables compatible portable devices such as laptops, tablets and smartphones to stream audio wirelessly to the
interface, and thus into the audio system of the Zone where the interface is installed.
The BT-1 is connected to the host unit’s Facility Port or Extension Port by a single Cat 5 cable. Alternatively, it may be connected
to remote Cloud input modules such as the LM-2, LE-1 and BE-1 in “daisy-chain” fashion, these modules being connected in
turn to the host unit. Screened Cat 5 cable and shielded RJ45 connectors should be used in all cases. If the Zone where the
BT-1 is installed also requires RL and RSL Series remote control plates, they may be “daisy-chained” to the BT-1 instead of being
connected to the host unit, which will simplify installation wiring in many cases.
BT-1 variants
There are two primary variants of the BT-1: the BT-1F, suitable for use with host units tted with one or more Facility Ports, and
the BT-1E, suitable for use with host units tted with one or more Extension Ports. The BT-1F will route an (L+R) mono sum of
the streamed audio to the host unit; the BT-1E routes the audio in stereo.
Variant BT-1F may be used with the following Cloud products, which are tted with Facility Port(s):
• Z4MK4 and Z8MK4 Zone Mixers
• Z4MK3 and Z8MK3 Zone Mixers
• 46-120 and 46-120MEDIA Zone Mixing Ampliers
• MA40F, MA40T and MA40E Mini Ampliers
Variant BT-1E may be used with the following Cloud products, which are tted with Extension Port(s):
• DCM1 Digital Control Zone Mixer
• DCM1e Ethernet Digital Control Zone Mixer
BT-1E and BT-1F variants may be distinguished physically by an ident on the rear PCB: a black mark will be visible in one of two
checkboxes:
• DCM1: BT-1E
• FACILITY: BT-1F
Additionally, the BT-1 is available in two form factors to suit either UK single-gang or US standard dual-gang electrical back
boxes; US-size modules are denoted by a sufx ‘A’ to the Part No.
UK-size modules are available either in white (a further sufx ‘W’ to the Part No.), or black (sufx ‘B’) nish.
NOTE: Unless specically stated otherwise, all references to “BT-1” in this Installation Guide can be taken to apply to all BT-1
mechanical and cosmetic variants.
Mounting - mechanical
BT-1 (UK version)
The Cloud BT-1 (BT-1FB, BT-1FW, BT-1EB, BT-1EW) ts a standard UK-style single-gang electrical back box. The box used should
have a depth of at least 35 mm.
BT-1A (US version)
The Cloud BT-1A (BT-1AFW, BT-1AEW) ts a standard US dual-gang electrical ‘J’ box in vertical orientation. The box used
should have a depth of at least 1½”.
