MONO PREAMPLIFIER

SOLO

The Solo preamplier is comprised of separate chassis and

power supplies for true monaural operation. The Solo uses

discrete Class A circuitry and is fully balanced throughout the

signal path. Like all Viola products the Solo input impedance

is 1 million Ohms. This high input impedance provides a

light load to source output stages which usually consist of

ampliers with limited drive current. Also the fully balanced

topology provides maximum rejection of common noise. The

Solo also features a choke input power supply. This helps

avoid high peak charging currents that occur in capacitor

input power supplies that can contaminate power supply and

ground returns.

Expandable

The Solo is expandable with up to 32 slave units controlled

by a master. The master sends volume, balance; mute, remote

trigger and input select commands to all slave units connected

to the network for multichannel operation. Pairs and single

units can be assigned to a group. This allows independent

volume and balance control for up to 6 pairs of Solo.

Baton Remote Control

The Baton provides remote operation of input switching,

volume, balance, mute and the remote trigger control. The

Baton will also control the volume and balance of groups of

preampliers, so you can control the volume of center and

surround channels independently.
