Wireless Bose Link

The AL8 transmitter has the bandwidth to support up to 8 rooms wirelessly. It is capable

of transmitting control and audio information for each stream, but it cannot reproduce the

10v turn on voltage carried by pin 6. This means that any expansion product requiring

this turn on signal must be hard wired.

When an AR1 receiver is connected to a Bose link product, it becomes part of that

product. When an AR1 is used on a Lifestyle RoomMate set to room I, for example, the

AR1 will essentially become a room I product and will only be able to transmit room I

information. That is why only one AR1 can be used per room.

The AL8 can also be used to transmit to room O, however, it should not be used to

transmit a variable signal. There are two reasons for this. First, sound quality may suffer.

The AL8 will amplify the noise floor on a variable signal and that will usually produce

undesirable results. Secondly, and most importantly, the AL8 has a minimum input

signal requirement. If the input signal falls below a certain threshold, the AL8 will turn

itself off. This means that listening at lower volumes may result in an unwanted shut

down. Anyone who uses an AL8 on room O must transmit a fixed signal and therefore

must control volume at the destination device.
