Magnetic Field
CAUTION!Do notlocate sensitive high-gain equip-
ment such as preamplifiers or tape decks directly
above or below the unit . because this amplifier has
a high power density .it has a string magnetic field
which can induce hum into unshielded devices that
are located nearby . The field is strongest just above
and below the unit.
If an equipmentrack is used , we recommend locating
the amplifier ( s ) in the bottom of the rack and the
preamplifier or other sensitive equipment at the top.

Installation
1. 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 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.
2. 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.
3.HANDLING
Do not force knobs and connectors, as they could be damaged if treated with excessive force.
4. 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 so-called earth-loops, which can
cause hum: in the event of interference, try using the EARTH switch on the amplifier's rear panel.
5. CONNECTOR CABLES.
To connect the amplifier to the mixer, always make certain to use only signal cables(screened cables made
up to 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.
6. AIR CIRCULATION FOR COOLING.
Amplifier's correct cooling is ensured by an internal fan, the speed of which ins 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 f r 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.
9.PROTECTION AND MAINTENANCE.
Avoid exposing the amplifier to direct sun, strong heat, intense vibrations, very dusty or damp surroundings
or even worse, rain: this will avoid eventual malfunction, deterioration or even electric shocks and fires, in
the event of a breakdown, do not open the amplifier contact the nearest " T" service cent e.
10. CONSERVATION OF DOCUMENTS AND PACKING.
Keep this manual for future consultation. On this subject, remember that equipment always gets a better
price on the secondhand market if it has all its original documentation and packing as well as being
well-kept.

1. POWER ON
ON/OFF switch with indication LED.
2.LEVEL
Control of the input level of the external signal: operates with continual values which vary from"
fully closed"(position" "-the signal is not fed to the amplifier sections) to "fully open"(position"
0dB")-the signal is sent to the amplifier sections at the same level as that with which it arrives at
the input).
3. BRIDGE
This LED will be light up when you choose "BRIDGE" mode on the back panel of this unit. There's
only output in CHA.
4.PROTEC
If this LED light up, this indicates that one of the various safeguarding the different sections of the
amplifier and the loudspeaker enclosure has tripped due to an operating fault.
5. CLIP
Display the status of the signal is when it has already been regulated by the input level controls.
6.SIGNAL
Signal "STATUS" indicators: these are LEDs able to indicate, for Channels A and B, a signal
presence in the inputs of the amplifier.
7. AIR VENTS
Amplifier cooling system air vents.
8. OUTPUTS
Power out: outs should be connected to the loudspeaker enclosures. All "T" SERIES amplifier's
A,B and BRIDGED outputs have a NL4 connector. Only loudspeaker(or loudspeaker enclosure
systems)within the amplifier's declared power and impedance load range should be connected to
the amplifier's outputs(see technical specification).
9.GROUND ON/FLOATING
Controls the separation of the electrical earth from that of the chassis.
