INTRODUCTION 2
Thank you for selecting Coda Technologies and our precison line of of high denition,
high value audio components. The Control Amplier CSi Balanced is a precision device,
designed in an eort to provide the listener with unmatched sound quality, design,
and construction. The CSib will provide you with many years of listening enjoyment.
The Control Amplier CSi Balanced is the latest renement of the Control Amplier CSi,
itself a substantially improved evolution of the highly regarded Unison Ultra. Most notable
are the styling and industrial design changes, introduced with the CSi, bringing the CSib
harmony with the Coda C series line styling changes introduced in 2006.
The preamplier and amplier sections remain virtually unchanged from the Unison Ultra,
while the power supply and output stages have been improved to increase power to
220W per channel.
The CSib also includes an extended preamplier section incorporating a new balanced
audio input. The preamplier in the CSib has been fully modularized, becoming a seperate unit from the amplier itself and increasing future extensibility.
Other functional, optional, or operational changes are noted throughout this manual.
In order to operate your amplier properly and to realize all of the capabilites of the
CSIb, we recommend that you read this entire manual carefully to insure maximum
benet from your audio system.

To provide for adequate ventilation you should allow at least six inches of unobstructed
space above and a couple of inches on each side of the amplifier. Because of its large
power supply, a local magnetic field may be created and picked up by CD players,
turntables and similar equipment. For this reason you should provide at least a foot of
space between the CSib and these components.
A. INPUT SELECTOR
Signal inputs for Disc, Video, Aux and Aux2.
B. MONITOR
Signal inputs and outputs for a tape deck or other recording device.
C. PREAMPLIFIER OUTPUTS
Signal outputs for an additional outboard amplifier.
D. SUBWOOFER OUTPUTS
Variable outputs for a powered subwoofer which track the master volume. Future
upgrades will provide for these 2 outputs to be used independently for Subwoofer
and Center Channel control
E. AMPLIFIER OUTPUTS
Amplified outputs to connect to speakers. To ensure identical speaker phasing
connect both speakers with the same polarity (positive to positive, negative to
negative).
F. POWER SWITCH
Main power switch. This power switch is intended only for complete shutdown while
connecting and disconnecting cables. The rocker switch must be in the “ON” position
for the CSib to operate. Rather than switching off the amplifier entirely when it is not in
use, the bias pushbutton on the front panel should be used to toggle the amplifiers
bias off when it is in standby.
G. AC LINE INPUT AND FUSE HOLDER
110 or 220 volt power input, fused as specified on the rear panel. To replace a
blown fuse, insert a small screwdriver into the slot next to the fuse drawer,
indicated by a fuse icon, and twist to release the drawer. Replacement fuses must
match the original fuse as specified on the rear panel.
