Page 3: Introduction
In a distributed sound installation, it is required that the power supply and BUS (12V, 0V, B) use a different LIYCI cable of the one carrying the audio signals (L, R, GND). Just passing one of them by an external wire or in another cable may cause noise in the installation. -
Page 4: Arquitecture Of The Installation
V = I x R That is, if we have 3 audio units we have three times more loss at the source than if we had only one unit. This loss is imperceptible for a few units (3 or 4), because normally the input impedance of the audio units is much higher than the output impedance of the source (typically a ratio 1:10). -
Page 5: Connections And Protections
CONNECTIONS AND PROTECTIONS The ONLY audio units are fed from a 12V power source placed in the switchboard. The ONLY amplifier is powered by 230V~, each having its own power supply. It is suggested to use a circuit breaker for protection of the whole audio system. - Page 6 When there is audio on more than one floor, a circuit breaker should be provided in the switchboard to protect the feeding of the amplifiers of the floor: one should never bring phase and neutral of the sound of the lower floor up to this floor.

Page 7: Configuration
4 LIYCY CONFIGURATION The ONLY audio units can be controlled by the automation buttons, commands from the remote controls, security system or from computers or smart phones. The functions that can be controlled remotely are: - switching on and off... - Page 8 0, the unit is switched off. To program buttons to control the audio unit in the bathroom (zone 2) proceed as follows: 1. Choose the command ON/UP for the button that you wish to turn up the volume and the command OFF/DOWN for the button that you wish to lower the volume.

Usually, an X2 capacitor 100nF mounted next to the load causing the noise (e.g. lamp or shutter) should filter out the switching noise. ENANCER Electrónica S.A. Page 9 of 9 Rua Max Grundig 9 4705-820 Braga Portugal info@only-smartbuildings.com Tel: +351 253 221 484 www.only-smartbuildings.com...
