a) Signal inputs. The signal inputs require a XLR-3 connector.
They are balanced using Pin 2 (XLR) as live (+), Pin 3 as return (-)
and Pin 1 as shield (chassis).
IMPORTANT: If balanced signal is not available, DO NOT
connect pins 1 and 3 together. Pin 1 should be left uncon-
nected and Pin 3 should be connected to the cable shield.
b) Loudspeakers. Loudspeakers are connected through BIN-
DING POSTS. 4 mm section multi -wire conductor are most
recommended, being the polarity as follows: RED for the po-
sitive (+) loudspeaker's terminal and BLACK for the negative (-)
loudspeaker's terminal. Outputs LEFT & RIGHT are available to
connect the satellites or the Mid-high. The SUBWOOFER output
is used to connect the low frequency reproduction speakers.
c) Mains 230V (+/-10%, 50-60Hz). The main connection is
a) Installation. The TP2400 may be installed in a standard 19"
Rack, occupying 2 U (88.9mm) height, or on any shelf or location
if the installation is fixed. In both cases make sure that the air flow
is not blocked in any way.
Do not install inside closed locations without good air circulation.
b) Connection of pre-amplifier units. For sound sources con-
nection, a professional Mixer with balanced outputs is strongly
recommended. The outputs of this mixer should be connected
to the TP2400 using XLR connectors (pin 1 shield, pin 2 live, pin
3 return) to obtain the best performance. The connection cable
should be twin conductor and shielded.
c) Connection of Loudspeakers. Speakers of either 4, 8 or 16 Ohm may be used provided the minimum total impedance of the
amplifier (4 Ohm per channel) is maintained. Connect speakers
in parallel for best results. Avoid combinations in series or series/
parallel. This will not cause any damage to the apparatus but can
be detrimental to the general quality of the system.
To the Left and Right outputs the Mid-High frequency louds-
peakers (Satellites) may be connected. The power delivered by
each of these outputs is of 500W at 4 Ohm, so the following
combinations may be used:
-1 Speaker of 4 Ohm nominal impedance with a minimum power
handling of 500W
-1 to 2 Speakers of 8 Ohm with a minimum power handling of
250W each, connected in parallel
-1 to 4 Speakers of 16 Ohm with a minimum power handling of
125W each, connected in parallel.
At the Subwoofer output, the speaker system for the reproduc-
tion of low frequency should be connected. The power delivered
at this output is of 1.400W at 4 Ohm, so 1 to 2 subwoofers of
800W at 8 Ohm or 1 subwoofer of 1.400W at 4 Ohm may be

done with the supplied IEC/SCHUKO cable. It is recommended
to always use the supplied cable, because it has the suitable
cross section to hold the power drawn by the TP2400.
d) Ventilation. The TP2400 is cooled by forced ventilation by
means of two fans located at the rear. The fans take the air in the
amplifier from the back, and take it out through the grill on the
front panel. Do not block the air intakes and outlets. The air flow
is adjusted according to the temperature, starting at half speed
and increasing it when the power modules or the mains transfor-
mer exceed 55º.

used (e.g. 2 x 15" or 2 x 18").
It is important to point out that the Limiter Adjust available for
each channel allows the user to match the output delivered by
the amplifier to the power handling of the available loudspeakers,
when these ones have lower power handling.
For the loudspeaker connections, twin conductor cable with a
minimum section of 4 mm should be used, or even greater if the
distance between amplifier and loudspeaker exceeds 20 m.
Polarity (+/-) should be maintained throughout the installation.
Phase inversion in any of the connected units will cause various
frequency cancellations that will adversely affect the sound res-
ponse of the system.
IMPORTANT: If for any reason a short-circuit may occur in any
of the speaker lines, the short-circuit protection circuit lights the
PROTECT LED (red) and completely cuts the power output of
the affected channel until the fault is corrected. This guarantees
protection of the speakers and power stages.
d) Location. The Mid-high frequency units (satellites) should be
installed on specific stands more than 2m high (between 2.5 and
4m). The best location for the Subwoofer units is at floor level in
