Bel Canto Design eVo200.2 manual Initial Setup, Line Level Inputs, Mono mode operation

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.
