1.2 Mounting

All T Series amplifiers are previewed for the standard 19" rack mounting; there are four front panels holes and fout rear
lateral holes. The amplifiers must be fixed into rack in both sides, back and frontal, to avoid mechanical damages. Your
amplifier uses a forced-air cooling system to maintain a low, even operating temperature. Drawn by an internal fan, air
enters through the slots in the front panel and courses over and through components. The T Series amplifiers feature
an "intelligent" variable-speed DC fan which is controlled by heat sink temperature sensing circuits: the fan speed will
increase only when the temperature of either heat sink requires it, which keeps fan noise to a minimum and helps cut
dust accumulation inside. Under extreme thermal load, the fan will force a very large volume of air through the heat
sinks. If either heat sink gets too hot, its sensing circuit will reduce the output power. If the amplifier overheats, another
sensing circuit shuts down its circuit to cut off power until it cools to a safe temperature.
The exhaust cooling air is forced out through the rear of the chassis (see figure 1.2.1), so make sure there is enough
space around the sides of the amplifier to allow the air to escape. If it is rack mounted, make sure the exhaust air can
flow without resistance. If you are using a rack with closed backs, there must be at least one standard rack space of
opening in the front of the rack for every four amplifiers. Amplifiers may be stacked directly on top of each other (no
space needed between units), starting from the bottom of the rack.

1.3 Operating Precautions

Make sure the AC mains voltage is correct and is the same as that printed on the rear of the amplifier. Damage caused
by connecting the amplifier to improper AC voltage is not covered by the warranty. Make sure the power switch is off
before making any input or output connections.
It is always a good idea to have the gain controls muted during power-up to prevent speaker damage if there is a high
signal level at the inputs.
Whether you buy them or make them, use good-quality input and speaker cables. Most intermittent problems are
caused by faulty cables. Use good-quality connectors and wire, along with good soldering technique, to ensure
troublefree reliability.

1.4 AC Mains connection

The AC Main connection is made via the CPC type connector (IEC20Afor T Five) on the rear side of the panel. The
figure below shows the connection to the amplifier. Be sure that your AC mains power source has the requirements
indicated in this manual.
network interface. The amplifier is a resistive load for the mains network, minimizing the reactive power and the
harmonic distortion on the current. The system allows performance to be maintained even in circumstances of varying
the mains voltage. Is important to connect the ground for safety, do not use adapters that disable the ground.
