Introduction
We would like to take this opportunity to thank you for selecting the CTA520 Power-amplifier.
We at Copland wish you many enjoyable hours in the company of fine music.
Please read this owners manual before operating the equipment.
CAUTION!
Various regulation agencies require us to bring the following information to your attention.
Please read carefully.
WARNING
!
To prevent fire or shock hazard, do not expose this unit to rain or moisture.
!
Check that your supply voltage is the same as indicated
!
Dangerous voltage inside. Do not open the cabinet. There are no user
serviceable parts inside. Repairs should be carried out by qualified service
personnel only.
!
Ensure that no objects or fluids pass through the ventilation openings.
If liquid is spilt into the amplifier, disconnect from the mains and consult a
qualified service technician.
Installation
Open the carton and remove the amplifier from its plastic bag. The AC-power cord is placed
in the bottom of the carton. Before placing the unit in your home read this carefully.
Do not subject the amplifier to high mechanical vibration.
The trouble free life of an electronic instrument is greatly extended by providing sufficient
ventilation to prevent the build up of high internal temperatures that cause deterioration.
Allow enough clearance so that cool air can enter at the top. With adequate ventilation the
amplifier can be mounted in any position.
The recommended minimum space is 45 cm deep, 45 cm wide and 30 cm high.
Inputs
The CTA520 power amplifier has two inputs. A balanced mono input via XLR socket and a
non-balanced stereo input via RCA-sockets. If used with a balanced pre-amplifier, two CTA-
520 power amplifiers will be necessary for stereo reproduction.
Use shielded cables to connect the input and outputs to signal sources.
To minimise the possibility to hum, the shielded cables should run parallel to each other or
loosely twisted together. Locate the cables away from speaker leads and AC power cords. All
connections is made on the back panel of the amplifier.
Outputs
Selection of the proper gauge wire to connect the loudspeakers reserves the quality of sound
reproduction for which the loudspeakers was designed.
If undersized wire is used, resistance is added to the amplifier/loudspeaker combination which
adversely affects the performance. Added resistance cause reduction of damping
characteristics and changes in frequency response.
