INTRODUCTION 2
Thank you for purchasing the AMPLIFIER 15.0.
This amplifier is a precision device, designed in an effort to provide
the listener with unmatched sound quality through superb design
and construction.
Although its operation is fairly simple, in order to operate your
amplifier properly and to realize all of the capabilites of the
AMPLIFIER 15.0 we recommend that you read this entire manual
carefully.
INITIAL SETUP 3
WARNING: Please ensure that the power switch is turned OFF while you are connecting the
amplifier. Connecting or disconnecting cables while the amplifier is powered on could
cause damage to your speakers.
The diagram below shows the default connections necessary to operate the AMPLIFIER 15.0
as a stereo amplifier. This is the simplest and most common mode of operation, and the
quickest way to get started. Once these connections are made you can turn the power
switch on, enable the bias from the front panel and start listening to your amplifier.
For simplicity this diagram shows an audio configuration using balanced interconnects. This
is the default input mode of the amplifier. Unbalanced operation requires that you set the
appropriate input mode as detailed on page 5.
NOTE: Ensure that the mode switch located between the input jacks on the rear of the
amplifier is set to the stereo position for normal operation. Bridged operation is explained on
page 7.

DETAILED INSTALLATION 4
I. Connections
The connectors and controls are clearly marked on the back panel of the amplifier.
Note the correct left or right channel orientation. The function and channel markings on
the rear panel correspond to the front panel controls and their signal paths.
1. The unbalanced and balanced inputs should be attached to the
appropriate unbalanced and balanced outputs of a preamplfier either directly
or through a crossover or processor, as appropriate to the application.
2. The left output and right output should be attached to the left and right speakers
respectively.
WARNING: There are no fuses on the amplifier’s outputs in order to cut down on
output impedance effects. Speaker protection is left to the manufacturer of your
speakers, as they would best know how to protect their product.
3. The AC line input should be connected to an AC outlet with the power cable
provided with the amplifier.
4. The fuse and voltage selector unit houses a 5x20mm slow-blow fuse and a voltage
selector cartridge. Ensure that the voltage, visible through a small window next to the
AC input, is set to the appropriate voltage for your country. When changing voltages,
ensure that the power cable is disconnected from the amplifier.
NOTE: If the fuse in your amplifier blows, contact a Coda dealer or call Coda
directly before attempting to use the amplifier again.
5. The power switch can usually be left on when the amplifier is functioning correctly.
With the bias disabled the amplifier will draw negligible current and can thus be left in
“standby” indefinitely.

3. The MAIN POWER switch, once all appropriate connections are made, may be left on
as the AMPLIFIER S5.5 draws a negligible amount of current when the BIAS is turned off.
4.The FUSE AND VOLTAGE SELECTOR houses a 5 X 20 slow blow fuse and voltage selector
cartridge. Should the fuse blow, contact a Coda dealer or call Coda directly. When
changing the fuse, or altering the voltage selection be sure this unit is disconnected from
