The normal arrangement of the Systemline Modular system is to use pairs of in-ceiling speakers. Each pair of speakers is made up of one speaker with the amplifier attached and one conventional speaker (ALM3/IR). For bathrooms where there is insufficient room for a pair of speakers, a single active speaker can be purchased and used in 'mono mode'(SLM3/IR). The active speakers can be purchased with a built-in IR sensor (eg ALM3IR).
Systemline Modular uses the professionally balanced line standard for transmitting the audio. This ensures almost perfect signal transmission and provides high immunity to noise and electromagnetic interference. The active speakers with their perfectly matched Class D digital amplifier to drive arrangement, make excellent use of this high quality signal.
Systemline Modular uses an extremely efficient design, so that when in standby or in use, it does not waste energy and is extremely cool running. No special provision needs to be made for ventilation when installing this system.
