from side to side in the amplifier. If you look closely, you will see
crosscuts in the side plates of the amplifier. These cutouts provide the
air intake and exhaust for the forced-air cooling system. The fans’
superior engineering and ball-bearing construction allow them to run
extremely quietly. Most people will never notice them. The only time
you are likely to hear them is when you first turn the volume off after
a prolonged period of extremely high volume listening.
Regardless of where you choose to locate your amplifier, we advise
locating the amplifier near the floor and well away from sensitive low-
level components. The Bravo power amplifier dissipates approximately
350 watts of energy as heat when on and at idle (no input signal). It is
therefore normal and perfectly safe for them to run somewhat warm.
Mechanical drawings are included in this manual to facilitate special
installations where necessary (see "Dimensions" at the end of this
manual).
SPECIAL DESIGN FEATURES
Congratulations on your purchase of a BRAVO Reference Amplifier
by Viola Audio Labs. While your new amplifier is straightforward in
everyday use, it includes several design features that are responsible
for its outstanding performance. In particular, your new power
amplifier defies the accepted wisdom that it is impossible to design a
large, powerful amplifier that also has all of the finesse of the finest
smaller amplifiers. A few of the technical highlights that make this
possible are given below.
Power Supply
The Bravo power amplifier used as a two box set is a stereo
amplifier with separate power supply. The separate power supply
assures complete freedom from electro-magnetic interference (EMI)
produced by the electromagnetic power supply components, i.e. the
power transformer and inductor (or choke).
The inductor (choke) input filter power supply design was chosen
because it produces far less EMI than conventional capacitor input
systems. The inductor (choke) input filter system greatly reduces the
electrical stress placed on the power supply components. Therefore,
