Description

Viola Labs Sonata PreAmplifier

 

The Viola Labs Sonata uses a 4.3’’ TFT color touchscreen display for navigation along with a high quality optical encoder using a magnetic indexing mechanism for volume and balance control.

Power Supply

The Sonata preamplifier uses a separate regulated power supply. Separate regulated supply sections are used for analog circuitry and digital control functions. The main analog power supplies use a choke input design followed by a dual tracking discrete regulator. Printed circuit board mounted low ESR capacitors are used for supply filtering.

Circuit Topology

The Sonata is based on the topology of the Crescendo preamplifier. The Sonata uses the OPA-1 discrete low noise, high speed operational amplifier module. The OPA-1 high current output stage will drive high capacitance cables and power amplifier input stages. The Sonata volume and balance control uses discrete high precision resistors. An additional dual tracking regulator is used for local power supply regulation.

Audio Design

The Viola Labs Sonata chassis design follows the classic design of the Cadenza preamplifier. The Sonata uses a 4.3’’ TFT color touchscreen display for navigation along with a high quality optical encoder using a magnetic indexing mechanism for volume and balance control. The Sonata can be controlled by using the Viola Remote Apple iOS™ application or RS-232. The Sonata preamplifier has a +12V trigger output to remotely control power amplifiers. Viola Link bus connectors also provide control of the external Sonata power supply and Viola Concerto power amplifiers. USB master ports are provided for firmware updates.
