Connecting and Use
Connecting the Orfeo 60 into
Your System
Input Connections
There is one RCA input jack and one XLR
balanced connector for the analog inputs. Both
inputs have the same signal path and
performance and may be used with any high
quality cable set
Loudspeaker Connection
The loudspeaker connections use one of the
two pairs of output jacks behind the output
transformer on the top plate of the chassis.
The output jacks accept many types of wire
termination, although we recommend either a
high quality spade lug or the use of simple
tinned wire terminations for this hookup.
Determine the nominal impedance of your
loudspeaker. The 8 ohm outputs should be
used with loudspeakers which have greater
than 6 ohm minimum impedance. The 4 ohm
connections should be used with loudspeakers
with 3 to 6 ohm minimum impedance. These
two options encompass the majority of
loudspeakers. The power toggle switch
between the output jacks is used to select the
impedance.
Power Switch
The rear panel power switch marked 0 1 will
take the amp out of standby when switched to
the 1 position. The input and driver tube
filaments are always powered to insure a gentle
turn on and instant sound output.

Tube Life and Replacement
The 845 output tubes are designed for
commercial use in and will provide at least 8000
hours of life as used in the Orfeo circuit. This
translates to 5 years of typical use. The input
tubes generally have 2000 hour life and will
need replacement every 1 1/2 to 2 years.
These tubes are available off the shelf from
current production at reasonable prices.
Contact your dealer or Bel Canto Design for
replacement.
Remote Power Switch
This connector is used to put the amplifier into
and out of standby operation remotely either
from an optional remote switch box or from a
Bel Canto preamplifier.
