Installation ultra-compact amplifier
These two ultra-compact amplifiers designed for fixed installation that require high quality audio amplification. They feature a class D amplifier and respectively deliver 2x25 W and 2x150 W output power. Thanks to their reduced size and DIN-rail format, they go unperceived in the installation.
SLA amplifiers are controlled through RS 485/DMX or VCO (0-5 V). In DMX mode, the same channel controls volume and Standby. In Command mode, a set of commands is available to control each channel separately.
It is necessary to adapt the power supply of SLA amplifiers to the installation requirements. The two tables of the next page explain which power supply units are adapted to each amplifier.
Features:
- Ultra-compact amplifiers with Class D technology.
- Controlled through RS485/DMX or VCO (0-5 V).
- Gain and Standby mode controlled through a unique channel.
- Additional DIP switch for operating mode selection and DMX start up channel.
- Din-rail format to optimize its integration in any installation.
