Installation & operating instruction
Mains power connection.
Before connecting the amplifier to the mains power socket, make certain that the voltage
corresponds with that indicated on the rear of the unit (an allowance of 10% is acceptable).
Before connecting the power cable to the mains, always make certain that it is not
damaged and that there are no bare wires, always connect the power cable to the
amplifier before switching it on and only remove the cable after switching it off.
Switching on and off.
In an audio system, it's always better to switch power amplifiers on last and off first.
Remember to switch off the amplifier before connecting it to or disconnecting it from other
units and to switch always on first the mixer and then the amplifier: in this manner, peaks
which are annoying and sometimes dangerous particularly for the loudspeakers enclosures
are avoided. It is normal for the LEDs to light up for a few moments when switching on.
Handling.
Do not force knobs and connectors, as they could be damaged if treated with excessive
force.
Connections and prevention of possible interference.
Avoid installing your equipment near radios, televisions, etc., since they could cause noisy
disturbance. When connecting the other units in your sound system, watch out for to socalled earth-loops, which can cause hum: in the event of interference, try using the EARTH
switch on the amplifier's rear panel.
Connector cables.
To connect the amplifier to the mixer, always make certain to use only signal cables
(screened cables made up of two wires plus a braid screen), not power cables (speaker
cables, normally made up of two wires, usually with a greater cross-section): to connect the
amplifier to the loudspeaker enclosures, always use power cables, not signal cables, as in
the latter case in fact, the power from the amplifiers would be partially disperse because of
the cable's smaller cross-section.
Take care of the connector cables. Always hold them by the connectors, avoiding pulling
the wire and avoid knots and twists when coiling them: this gives the advantage of
increasing their life and reliability.
Air circulation for cooling.
Amplifier's correct cooling is ensured by an internal fan, the speed of which is controlled
by a special sensor (the speed is proportional to output power and therefore the
temperature generated):remember never to block the air vents located on the unit's sides in
any way: the air necessary for cooling passes through these.
If the amplifier is kept in a flight-case during use, make certain that it has sufficient openings
at both the amplifier's air vents. Avoid locating it very small spaces which don't allow correct
air circulation.

1. Balanced input(odB/30kOhm): For all the models, both CHA and CHB have
one pair of balanced input with cannon connector.
2. Power output: output should be connected to the loudspeaker. The CHA/CHB
outputs of DSP series amplifier have one waterproof jack and one group of
binding post.
Note:
The rated power and the impedance load of loudspeaker or loudspeaker system
must match the amplifier(see technical specification). Please use the speaker
cable only(normally provided with one red and one black wire). Do not use the
signal cable( normally used for microphone and audio equipment).
3. Earthed ON/FLOATING
Separate the signal earth from the chassis.
Using this selector to break earth loops which can form when several units are
connected.
4. Power: AC 230V 10% 50-60Hz.
5. Air vents
Note:
The fan of the DSP series cooling system creates a flow of air with the direction from
front to back. That means the air is taken from the opening on the front and is
expelled through the opening on the front after cooling the heat sinks and
transformer.
Attention must be paid to avoid blocking these openings. And never place the
amplifier
in which there is not sufficient air circulation.

CONNECTOR CABLE
The following diagrams illustrate the wiring of the various types of sockets that can be
used with the DSP power amplifiers.
To connect the amplifier to the mixer, always make certain to use only signal cables
(screened cables made up of two wires plus a braid screen ), not power cables (speaker
cables, normally made up of two wires, usually with a greater cross-section): the use of
unscreened cables could in fact cause annoying buzzes and background noise. We
therefore always suggest the use of balanced cables for microphones and line units
whenever possible.
To connect the amplifier to the loudspeaker enclosures, always use only power
cables, not signal cables, as in the latter case in fact, the power from the amplifiers would
be partially dispersed because of the cable's smaller cross-section.
Take care of the connector cables. Always hold them by the connectors, avoiding
pulling the wire and avoid knots and twists when coiling them: this gives the advantage of
increasing their life and reliability. Check your cables periodically, making certain that they
are in good condition, that the connectors are correctly wired and contacts perfectly
efficient: in fact, many problems and setbacks (faulty contacts, ground hum, disturbance,
etc.) are due to the use of unsuitable of faulty cables.
