Concerto Power Amplifier

Housed in the same size billet Aluminum chassis as the Crescendo, the Concerto delivers 100W into 8 ohms and 200W into 4 ohms. Like all Viola power amplifiers the Concerto uses a choke input power supply. This reduces peak charging currents that are prevalent in capacitor input supplies. This minimizes intermodulation distortion on the power supply rails on ground returns.

Concerto Audio Design

The Concerto is a Class AB biased push-pull amplifier design. The Concerto incorporates Motorola ThermalTrak™ into the bias network. This provides fast thermal feedback information without the thermal lag of other bias topologies. A center chassis Venturi style heat sink provides cooling for the amplifier. Connections to loudspeakers are provided by a pair of WBT nextgen™ connectors per channel.

Network

The Concerto can be connected to the Crescendo preamplifier via the CAN (Controller Area Network) connector. When this is done Concerto status information including temperature and line voltage are transmitted to the Wi-Fi remote application. This also provides synchronization of the color displays and standby modes.
