room were you to find one that could do so). However, many high

quality loudspeakers may require rather extreme power levels on a

short term basis when reproducing music at realistic levels. Your new

amplifier can answer these needs with impunity, without any power

supply "sag" and without altering its sonic performance in any way.

The resultant imperturbable nature of these amplifiers is reflected in

the authority and control with which they reproduce music. Your

selection of any particular model depends only on the maximum power

you need, based on your loudspeakers, listening room, and listening

habits. Viola produces a line of loudspeakers that are designed to

match the Bravo amplifier. Ask your dealer about them.

Extensive Protection

Your new power amplifiers will shut themselves down if they sense

any of a number of fault conditions that could cause damage to either

themselves or to your loudspeakers. These fault conditions include:

• the presence of DC (direct current) at the output

• demand for excessive current (indicating a short circuit) at the

output

• either over-voltage or under-voltage conditions on the AC mains

• unsafe operating temperatures in any of several critical areas

within the amplifier.

In the case of either significant DC offset or an over-current

condition, the amplifier will shut down to protect itself and your

speakers. To restore normal operation, remove the cause of the fault

and cycle power (e.g., the AC mains power button).

If the AC mains voltage it either too high or too low for safe

operation, the amplifier will automatically shut down. The amplifier will

not turn back on until the AC mains voltage is again "legal" for normal

operation. As an example, a 120V unit will operate between

approximately 90-140V; a 240V unit will operate between

approximately 180-280V. Outside these generous limits, the amplifier

will shut off. Once the fault condition is removed, the amplifier can

again be turned on.

If the amplifier manages to become overheated despite the

innovative cooling system, it will once again shut down. Once the fault

condition is removed, the amplifier can again be turned on. In

addition, the AC input to each transformer is fused to protect against

excessive current conditions such as driving shorted outputs. Inrush

limiting prevents premature aging of power supply components during
