Bel Canto Design eVo200.2 - Manual (Page 6)

eVo200.2 Owner's Manual Page 6
Initial Setup
Line Level Inputs
Two inputs per channel are provided. The RCA
jack is a standard input that accepts single-
ended sources. The female XLR jack allows
true balanced hookup operation using the
standard pin configuration:
Pin 1 Ground
Pin 2 Input +
Pin 3 Input -
If there is a problem with noise or hum at the
amplifier outputs when using a single-ended
source, this may be due to the ground side of
the RCA jack is not connected to the circuit
ground of the amplifier. To connect this to the
ground depress the RCA/XLR switch button.
This should be adequate to correctly ground
most systems with stereo preamplifiers.
Loudspeaker Connection and
Power Output Options
Connect loudspeakers to the outputs of the eVo
amplifier using the 5-way binding posts located
the rear of the amplifier. The red or black center
plug in the output post can be removed for use
with banana type connectors. Unscrew binding
post until the gold pin in the bare wire hole is
visible. Remove the center pin by first pushing
one end in, and then, using serrated needle
nose pliers, pull the center pin out from the other
side. Do not connect speaker terminals to a
chassis or earth ground connection. The Anti-
Phase operation of the outputs would result in
one of the red (positive) outputs being
connected to ground and cause the amplifier to
go into protection mode and shut itself off. Also
when connecting the amplifier in balanced-mode
mono operation both terminals are driven
actively and can not be grounded. Make certain
that any output terminal is not connected to a
chassis or earth ground.
Mono mode operation
Mono power delivery can be obtained with the
simple push of a button. Connect one input
cable to any of the 4 input jacks and depress
the RCA/XLR button to select the appropriate
input. Then, depress the mono/stereo mode
button. The loudspeakers are then connected to
the output terminals indicated for mono-mode
operation on the back panel.
Power On and Operation
The rear panel has a master power switch for
the eVo200.2. The eVo200.2 has been
designed to remain powered up at all times. The
blue front panel LED is on when the eVo200.2
is in normal operating mode. When the amplifier
shuts down in protection mode a small red LED
lights next to the blue LED. If this occurs, turn
off the main power switch and insure that no
output terminal is connected to ground or to
another terminal. Restore power and the
amplifier should return to normal operation. If
not then there may be an internal fault and the
amplifier should be returned to an authorized
service center. Contact your dealer, distributor
or Bel Canto Design.
