INSTALLATION
The kit includes :-
The Loudspeaker, quick-fit housing, fire-dome and audio amplifier module.
A regulated, 230VAC to 12 Volt DC, in-line power supply (1000mA)
A 15 pin “D” type socket (solder-bucket type)
A 15 pin “D” type metalised hood
Installation instructions and drawings
UNBALANCED SOURCE INSTALLATION ( e.g. Adpro fast-scan, FastVu or FastTrace )
The audio cable may be a simple microphone type e.g. RS Stock-Code 181-900.
IMPORTANT NOTE! The screen or drain-wire must be earthed at the SOURCE EQUIPMENT end
and MUST be connected to the connector marked “SCREEN” in the CPS03 unit when using single-
ended configuration. The power supply unit supplied has a floating 0 Volt line and should only be
replaced with a similar type.
The 12 Volt DC power should be supplied via a separate cable to the audio cable and needs only to
be a twin core, low-Voltage type. This cable does not require a screen and should ideally be of a
1.0mm2cross-section.
NOTE:- The 12 Volt DC power cable should be kept as short as possible and, in any event, no
longer than 10 metres.
BALANCED-LINE INSTALLATIONS (FOR CPS03A VERSION)
The system may be installed with source equipment which provides a balanced-line output. These
sources are normally low-impedance (e.g. 600 Ohm). A balancing/matching transformer is fitted in
models with an “A” suffix.
The audio cable should be of a twisted-pair type with overall screen e.g. RS Stock-code 365-8775
The audio signals may be switched using the AVS BINREL02 switcher. This unit incorporates audio
transformers which convert the un-balanced signals to and from the ADPRO equipment to true
balanced-line signals. If using a BINREL02 switcher, please see the installation drawings later in this
document.
IMPORTANT NOTE! The screen or drain-wire must be earthed at the SOURCE EQUIPMENT end
and should be connected at the CPS03A unit when using Balanced-Line configuration. The power
supply unit provided has a floating 0 Volt line and should only be replaced with a similar type.
The 12 Volt DC power should be supplied via a separate cable to the audio cable and needs only to
be a twin core, low-Voltage type. This cable does not require a screen and should ideally be of a
1.0mm2cross-section.
NOTE:- The 12 Volt DC power cable should be kept as short as possible and, in any event, no
longer than 10 metres.
