Introduction and Key Features
Introduction
The C5 DSP amplifier systems from Coda Audio integrate light-weight power supplies, high
power sonically transparent class D amplifiers, complete system monitoring and a fully
featured USB or network controlled 24 bit 96kHz DSP processing platform as standard
Key features
•One or two dual amplifier sections : two or four channels
•Each section is completely independent with discrete PSU, amplifier and DSP
•Fully featured PC control and telemetry of single devices or networks as standard
•Coda Audio class leading Class D amplifier stages
•Minimal signal path and refined DSP algorithms for clean, dynamic and musical
audio performance

Mechanical Installation
The C5 DSP amplifier system is designed to be mounted in a standard 19” rack enclosure
Where the amplifier is used in a fixed installation, it is possible to use only the front panel
19” rack mounting holes to mount it in a standard rack enclosure If the amplifier is
mounted in a mobile rack it is recommended that the rear rack mounting kit is fitted so

8
the amplifier can be well supported Damage caused by insufficient support is not covered
by the warranty
To prevent damage to the front panel it is recommended that plastic cups or washers are
fitted underneath the rack mounting bolt heads
It is possible to mount multiple C5 amplifiers without ventilation gaps between them but it
is essential that an unobstructed flow of clean air is available from the back of the unit to
the front It is important the neither the air intakes at the rear of the unit or the exhaust
vents at the front are covered
The amplifier should never be exposed to rain or moisture during operation or storage If
the unit does come into contact with moisture, remove the AC power cord immediately
and leave it in a dry and warm location to dry out
Note that when any equipment is taken from a cold location into a hot humid one,
condensation may occur inside the device Always allow time for the equipment to attain
the same temperature as its surrounding environment before connecting the AC power
cord

C Power Connection
W RNING! THIS PPLI NCE MUST BE GROUNDED.
The amplifier must always be connected using a 3-wire, grounded AC supply The
framework of the rack mount enclosure should also be connected to the same grounding
circuit The unit should never be operated unless the AC power cable ground is correctly
terminated; this is important for personal safety and for control of the system grounding
The amplifier is supplied with a Neutrik PowerCon
TM
type locking AC power connector Use
only an AC power cord with a correctly terminated PowerCon
TM
type connector to make
the connection to the mains power supply
The C5 amplifiers are designed to operate on 50/60 Hz AC power The power supply
sections automatically configure themselves for either 115V or 230V nominal voltage at
turn on The amplifiers will operate over an extended range of supply voltages from;
nominal 115V / 230V +/- 10%
Note that whilst the amplifier will operate correctly at voltages indicated, the specified
output power will only be achieved when operating with the stated nominal voltages

udio Connections
For each amplifier channel there are female and male XLR input connectors which are
wired in parallel Typically the female connector is used for the audio input, the male XLR
connector being available to link the same audio signal to another amplifier channel
The HOT, + or ‘in phase’ connection should be made to pin 2 of the XLR connector
The COLD, - or ‘out of phase’ connection should be made to pin 3 of the XLR connector
Pin 1 of the XLR connectors is internally connected to the chassis The screen of the input
cable should always be connected to one of these points to ensure that EMC performance
and regulations are met The cable shield ground should also be connected to the source
device which is providing the input signal to the amplifiers
