CHAPTER 2 | FEATURES AND DESCRIPTION
FEATURES
• Superior Performance – Utilizes proven audio amplication technology to
deliver premium sonic performance.
• Easy Expansion – 16 channels available for all kinds of zoning
congurations in large or far reaching the properties.
• Power & More Power– 100 watts per channel at 4 ohms / 200 watts at 8
ohms bridged.
• Compact Design – At just 1RU high, the CP-16i leaves room to install
more components in the rack.
• Ultra-Ecient – Cool Power® Class D amplier technology ensures
ecient heat dissipation and low power consumption.
NOTES:
• Note that the CP-16i requires an external preamp for volume control.
• The CP-16i also supports a Bridge Mode (BTL) conguration. Bridge Mode
converts one stereo pair into a single, stronger amplication channel. If
all Zones are bridged, there are 8 channels available. Stereo and Bridged
Zones can be mixed as necessary.
Front Panel Components (LEDs)
The front panel features three LEDs.
POWER LED (Green/Red)
The Power LED indicates that the current power state of the amp:
• Green indicates that the amplier is On.
• Red indicates that the amplier is receiving power, but is in Standby mode.
OC/CLIP LED (Yellow/Red)
The OC/CLIP LED indicates that either the current of one or more of the speaker
outputs has exceeded its maximum or that the power supply is overloaded.
NOTE: The amplier outputs are limited to 20A peak each in order to protect
the power stages against overload during a short circuit, or over-current event
on the output of the amplier.
• Yellow indicates an OC (over-current) shutdown of the amplier output.
In the case of an OC event, the amplier will shut down to protect itself,
and indicate an OC event on this LED (yellow) and the OC pin (pin 8 on
the 10-pin I/O port - see page 15). An OC event can indicate a cable fault,
installation fault or defective speaker.

CHAPTER 2 | FEATURES AND DESCRIPTION
CP-16i REAR PANEL COMPONENTS
• Red indicates an overload event with the Power Supply. The LED will
light red if internal temperature sensors on the power supply sense an
abnormally high temperature, or if power supply over-current/over-load/
power-limit circuits are triggered. In either case, the power supply will
limit the amplier output to keep the power supply within safe limits, while
keeping the music playing.
THERMAL LED (Red)
The Thermal Protection LED indicates thermal shutdown of the individual zones
(amplier boards).
• The temperatures of all the output channels are individually monitored,
and if one or more of them reaches the thermal limit (105°C) then the
respective Zones will shut down and go into soft start mode (Channels 1/2
= Zone 1, Channels 3/4 = Zone 2, etc), and the Thermal Protection LED
will be lit.
• The other Zones will continue to be active. When the temperature has
dropped below the thermal threshold, the respective Zone(s) start up again
automatically.

CHAPTER 3 | INSTALLATION AND OPERATION
Controlling the CP-16i
The CP-16i can be powered on and o externally by using the two signals
12V trigger and 3-5V trigger. A Signal Sense function is also provided which
automatically can switch on the CP-16i in the event of an audio signal and
switch o the CP-16i to enter standby mode when no audio signal has been
present on the signal terminals for approximately 13 minutes.
NOTE: Volume control for the CP-16i is managed by an external pre-amp or
audio switcher.
Installation
Mounting the CP-16i into an Equipment Rack
The CP-16i can be mounted in a 19” equipment rack or on a solid at
surface. Use the included removable rack ears and removable feet for
mounting.
Ventilation
NOTE: The maximum operating ambient temperature is 45°C (113°F).
• To ensure that the rack enclosure is adequately ventilated, there must
be a minimum of 3” all around the CP-16i unit.
• Sucient airow must be achieved (by convection or forced-air cooling)
to satisfy the ventilation requirements of all the items of equipment
installed within the rack.
Rack Mount Safety Instructions
• Mounting of the equipment in the rack should be such that a hazardous
condition is not achieved due to uneven mechanical loading.
• Consideration should be given to the connection of the equipment to the
supply circuit and the eect that overloading of the circuits might have
on over current protection and supply wiring. Appropriate consideration
of equipment nameplate ratings should be used when addressing this
concern.
• Reliable grounding (earthing) of rack-mounted equipment should be
maintained. Particular attention should be given to supply connections
other than direct connections to the branch circuit (e.g. use of power
strips).

CHAPTER 3 | INSTALLATION AND OPERATION
Wiring and Connections
IMPORTANT NOTE: The amplier must be turned o whenever you make
changes to the input connections and speaker wire connections.
Connecting Audio Source Devices
Source Devices connect to the Audio (Signal) Inputs connectors on the rear
panel.
Audio (Signal) Inputs
The following table provides pinout information for the Audio Inputs:
SE/BTL (Stereo/Bridge Mode) Switches (1-8)
Eight SE/BTL slide switches (located between the two RCA/phono input
connectors for each Zone). These switches provide the ability to set each of
the eight Zones to either Stereo Mode (SE) or Bridge Mode (BTL). Note that by
default, all Audio Inputs are set to Stereo Mode.
• Stereo Mode (SE): In Stereo Mode, both channels are used for stereo
audio input. Stereo mode provides true stereo separation between the left
and right channels in each Zone.
• Bridge Mode (BTL): Bridge Mode uses one input channel of the amplier
to combine the power from both channels output into one single output.
In Bridge Mode, the odd channels are used for audio input and the even
channels are disconnected internally.

Cool Power® Audio Amplier
CP-16i
14
CHAPTER 3 | INSTALLATION AND OPERATION
Connecting Input Devices in Stereo Mode
Stereo input devices use both input channels (left and right) for each Zone.
• Odd-numbered channels (with white connectors) should be used to
connect to the left output on the source device.
• Even-numbered channels (with red connectors) should be used to connect
to the right output on the source device.
The CP-16i supports up to eight stereo input devices, each one associated with
an input Zone (1-8). Note that each Zone represents a stereo pair. For example,
Zone 1 consists of CH1 (left channel) and Ch2 (right channel).
There is a direct correlation between the audio inputs and the speaker outputs.
For example, a stereo device connected to the Zone 1 inputs (CH1 and CH2)
will output on the CH1 (left) and CH2 (right) speaker outputs:
NOTE: When connecting stereo input devices, verify that the Stereo/Bridge
(SE/BTL) mode switch for the Zone is set to “SE”. This is the default factory
setting.
Connecting Input Devices in Bridge Mode
In Bridge Mode, input devices connect to the left input channels only. Note that
left input connectors are white, and are the odd-numbered channels (CH1, 3, 5,
7, 9, 11, 13 and 15).
There is a direct correlation between the audio inputs and the speaker outputs.
For example, a bridged device connected to the Channel 1 input (CH1) will
output on the CH1 (left) and CH2 (right) speaker outputs:
NOTE: When connecting bridged input devices, verify that the Stereo/Bridge
(SE/BTL) mode switch for the Zone is set to “BTL” as shown above

CHAPTER 3 | INSTALLATION AND OPERATION
Connecting Speakers
All speaker connections must use Class 2 Wiring. Class 2 Wiring is required
due to the fact that power is above 10W per channel under normal operating
conditions.
Speakers connect to the captive-wire output terminals (CH1-CH16) on the rear
panel:
Each Zone (1-8) consists of two channels (an L/R pair in Stereo Mode),
and each Channel (1-16) uses a 2-pin captive-wire connector to connect to
speakers.
NOTE: For wiring runs longer than 80 feet, 14-gauge speaker wire is
recommended.
Speaker Output Connectors
The speaker output connectors consist of two 16 pin captive-wire terminals;
each of the output terminals having a “+” and “-“ terminal.
The label “BTL” on each speaker pair points to the pins that are used when
connecting a single speaker to an input in Bridge Mode.
The following table provides pinout information for the Speaker Output
Terminals

CHAPTER 3 | INSTALLATION AND OPERATION
Connecting Speakers in Stereo Mode
NOTE: When connecting stereo speakers, verify that the Stereo/Bridge (SE/
BTL) mode switch for the associated Zone is set to “SE”.
Stereo speaker pairs use both output channels (left and right) for each Zone.
• Odd-numbered channels should be used to connect to the left speaker.
• Even-numbered channels should be used to connect to the right speaker.
The CP-16i supports up to eight stereo speaker pairs, each one associated with
a Zone (1-8). This diagram illustrates the wiring connection from both Zone
output channels to a stereo speaker pair:
NOTE: If incorrect wiring is used there is a risk of electrical shock and a re
hazard.
The table below illustrates the direct correlation between the audio inputs and
the speaker outputs in Stereo Mode:

CHAPTER 3 | INSTALLATION AND OPERATION
Connecting Speakers in Bridge Mode
NOTE: When connecting a speaker to a “bridged” input, verify that the Stereo/
Bridge (SE/BTL) mode switch for the associated Zone is set to “BTL”.
In Bridge Mode, both channels in a Zone are connected to a single speaker, via
the positive (“+”) pins for both output channels:
NOTE: If incorrect wiring is used there is a risk of electrical shock and a re
hazard.
The table below illustrates the direct correlation between the audio inputs and
the speaker outputs in Bridge Mode:

The following table lists the pinouts for the I/O port

19
It’s Under Control®
CHAPTER 3 | INSTALLATION AND OPERATION
The function of each pin on the I/O port is described below.
Pin 1 - Signal Sense
Pin 1 on the 10-pin I/O port is used for single-ended Signal Sense input (+).
This pin detects an input signal from a source device when the source device
is active. Pin 1 (Signal Sense +) connects to one of the source device’s input
cables to provide a signal to the CP-16i when the source device is active.
Pin 2 - Signal Sense Input Ground
Pin 2 on the 10-pin I/O port is used for Signal Sense input ground (-).
PIN 1 Example - Signal Sense Connection (Unbalanced)
External Signal Sense Switch
With the External Signal Sense switch in the ON position, the amplier is
automatically turned on when an audio signal is present, and automatically
placed in standby mode when no audio signal has been present on the signal
terminals for approximately 13 minutes.
• Note that the example diagram indicates the Signal Sense connection tied
to the Left output from the source device, but Signal Sense can come from
either output.
• The amplier will power up if a signal is applied to the signal sense input.
By default, the External Signal Switch is set to the ON position.
Pin 3 - 12V (In) Trigger
The CP-16i can be turned On or placed in Standby mode externally via a 12V
Trigger signal. A 12V trigger input is accessible via Pin 3 on the 10-pin I/O port.

CHAPTER 3 | INSTALLATION AND OPERATION
Pin 4 - Trigger (Loop Out)
The CP-16i also provides a convenient way to daisy-chain a 12V trigger to other
devices. Any voltage provided to Pin 3 is looped out to Pin 4 of the 10-pin I/O
port:
Pin 4 = 12V Trigger (Out)

PIN 4 Example - Trigger (Loop Out) Connections
Pin 4 connects to a +12V Trigger (input) on a downstream amplier
NOTE: Pin 3 and Pin 4 are hard wired together. Therefore, when a trigger is
applied to pin 3 it will also be present at pin 4. Pin 4 will be high only if a signal
is applied to Pin 3.
Pin 5 - Local/Trigger GND
Pin 5 on the 10-pin I/O port provides a ground connection for the 3-5V Logic
Level Trigger. Pin 5 connects to the GND pin of an I/O port on an external
controller.
Pin 6 - 3-5V Logic Level Trigger
The CP-16i can be also turned On or placed in Standby mode externally via a
3-5V Logic Level trigger signal. A 3-5V trigger input is accessible via Pin 6 on
the 10-pin I/O port.
3-5V Trigger Switch
The 3-5V Trigger Switch has two selections; High and O.
When the 3-5V Trigger Switch is set to High, the amplier will turn on when AC
mains is turned on, For example, the 3-5V Trigger switch could be set to High
if the amplier needs to be forced on without having signal sense or external
trigger signals.
