We would like to take this opportunity to thank you for selecting the CTA405 amplifier.

We at Copland wish you many enjoyable hours in the company of fine music.

Please read this owners manual before operating the equipment.

Various regulation agencies require us to bring the following information to your attention.

Please read carefully.

To prevent fire or shock hazard, do not expose this unit to rain or moisture.

Check that the transport protection of the output valves has been removed.

as described below under "installation".

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.

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.

To prevent the output valves from disconnecting and being damaged during transport,

a piece of red foam plastic has from the factory been placed between the output tubes

and the top cover of the chassis.

The reed foam plastic are clearly visible through the ventilation holes in the top cover.

Please make sure that the protective foam plastic has been removed before use of the

amplifier.

Do not subject the amplifier to high mechanical vibration, the valves are sensitive to this.

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.

Use shielded cables to connect the signal source to the amplifier input. 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.

Selection of the proper gauge wire to connect the loudspeakers reserves the quality of sound

reproduction for which the loudspeakers has been designed. If undersize wire is used,

resistance is added to the amplifier/loudspeaker combination, which adversely affects the

performance. Added resistance causes reduction of the damping characteristics.

All connections is made on the back panel of the amplifier.

The amplifier AC power cord is plugged into a 110/120/220/240 volt 50/60 Hz wall outlet. The

right voltage is indicated on the back panel just beside to the AC power inlet.
