Overview
This compact four channel Class-D design amplifier provides four independent 240W power amplifiers built into a single 1RU 19” rack mount chassis. It is ideal for use in environments where four individual program sources are required in different building zones. Ideal for use in hotels, function centres, shopping malls and commercial offices.
The unique feature of the Class-D design is the significant reduction in power consumption and heat generation due to the switchmode power supply design employed. They utilise active power factor correction (APFC) switch mode power technology allowing an efficiency rating of 85%. The result of which is a much cooler running amplifier (<55°C), offering a long life span and significant power savings for a reduced environmental impact.
Each amplifier is provided with screw terminal connections for balanced input from the source and 100V line output. Each channel amplifier is provided with front panel level controls and indicators. A dedicated 24V DC power battery backup input is also provided for each channel.
All amplifiers are also protected against short circuit, high temperature and overload conditions. Importantly these protections are dedicated for each channel, so that if a fault occurs on one amplifier, the others are unaffected
