2.1 User’s liability
• Damages to the loudspeaker systems
Always check the peak and continuous power of the loudspeak-
ers. This amplifier is extremely powerful and can be potentially
dangerous both to the loudspeakers and to persons. Most loud-
speakers may be easily damaged or broken, especially by ampli-
fiers operating in bridge. Even if there is a gain reduction through
the attenuators on the amplifier’s front panel, it is still possible to
reach the maximum output power if the input signal level is high
enough.
• Dangerous output voltage
The amplifier can generate hazardous output voltage. Do not
touch exposed cables of loudspeakers with the amplifier in op-
eration.
• Radio interferences
A sample of this product has been tested and approved to meet
the requirements of the Electromagnetic Compatibility Directive
(EMC). These requirements have been defined so as to provide
reasonable protection against dangerous interference of electri-
cal equipment. Whenever this product has not been installed or
handled according to these guidelines, it might interfere with other
equipment such as radio receivers. However, there is no guaran-
tee that they should not occur in a specific installation. Should
this equipment interfere with transceiver equipment (such possi-
bility can be checked by switching on and off the device), the user
should try to cancel the interference by observing one or more of
the following measures:
- increase the distance between the device and the receiver;
- connect the device to a plug linked to a different circuit from the
one to which the receiver is connected;
- redirect or move the receiver’s antenna;
- make sure that the unit concerned conforms to the EMC immu-
nity limits (CE-labelled). All electrical equipment sold in the EC
should be approved concerning the protection against electro-
magnetic fields, high tension and radio interference;
- contact qualified personnel.

4. Brief description of the product range
The Digital Technology Series amplifiers are available in four
models with different power outputs and number of channels.
XTDT3200 and XTDT3800 are two-channel models with a power
supply of up to 1600 W and 1900 W respectively per channel at 4 Ω.
XTDT4800F and XTDT6000F are four channel models supplying
up to 1200 W and 1500 W respectively per channel at 4 Ω.
All XTDT series amplifiers have been fully designed with switching
technology (both the supply power unit section and the power stage)
to obtain high power and performances with a very low weight,
a result which cannot be achieved with traditional configurations.
These features make this series particularly suitable to meet the
typical requirements of the professional audio sector: power, low
weight and high performance (and, therefore, low consumption).
All Digital Technology Series amplifiers are equipped with an
integrated controlled system which protects both the amplifier and
its load. The signal is constantly monitored, with a level control
and indication through a LED on the front panel. An in-built limiter
protects the loudspeakers from any damage caused by distortion
signals. As far as temperature is concerned, the control system
maintains the necessary conditions for a correct operation of
the power components. The output signal control protects the
load from high current values or from the presence of live DC
components. Moreover, the Digital Technology Series amplifiers
contain a selectable hi-pass filter (30 or 75 Hz) designed to adjust
the amplifier to the connected loudspeaker systems.

Owner’s manual
5. User instruction
5.1 Maximum power consumption
Check whether there is enough power to supply the amplifier
(refer to the data at the end of this manual). Please ensure that
the voltage of the network complies with the instructions found at
the back of the amplifier. Maximum power consumption is limited
solely through the internal fuses.
Warning: before any audio connection keep in mind that
the regular procedure is to turn off the amplifier and to
unplug it from the mains, and set the volume tuners to the
minimum during start up.
5.2 Cooling
Pay particular attention to the ventilation/cooling conditions of the
amplifier. An internal system of forced airflow, by a variable speed
fan, allows cooling of the dissipators from the heat generated by
power parts. The airflow is directed from the front panel to the
back panel of the amplifier, which means that the air is drawn in
from the front and is discharged through the back opening.
Pay particular attention to leave enough space in front of the am-
plifier to allow the air to go in and enough space at the back to
allow it to come out. If the amplifier is installed in a rack strand,
make sure that there is enough air clearance: air should easily flow
through the amplifier and meet no resistance.
5.3 Settings
Make sure that the equipment is turned off before setting it ac-
cording to your needs.
It is also possible to set the amplifier for the following functions:
• Gain
One of the main advantages of XTDT amplifiers is the sectable
input gain for each channel, thanks to proper DIP switch that are
placed in the rear pannel. The user is able to calculate the right
Sensitivity value starting from the maximum output voltage and,
obviously, the driven load.
In particular:
VMAX = (PxZ)1/2, where P = power and Z = impedance;
VMAX (dBu) = 20 log VMAX / V0, where V0 = 0.775 V;
Sensitivity (dBu) = VMAX(dBu) - Gain (dB).
• Selectable filter for low frequencies
Your amplifier is equipped with an HPF filter that can be selected
for every channel. To set the cutting frequencies use DIP switches
that are placed in the rear pannel of the amplifiers; the cutting
frequencies available are 30 or 75 Hz. When the filter is disabled,
the amplifier will still be protected by the input DC.
• Stereo mode (standard)
When using stereo mode every channel operates independently
and its input attenuators control the respective level.
The minimum recommended load for running in stereo is 2 Ohm
per channel for XTDT3200 and XTDT3800 and 4 Ohm per chan-
nel for XTDT4800F and XTDT6000F (please refer to technical
specifications).
The input signal can be connected by using Combo© connectors
cabled on the back panel. The loudspeakers are linked to the out-
put connectors speakon A-B (C-D) (refer to fig. 5).

• Bridged mono mode
The bridged mono mode is enabled when the Link/Bridge switch-
es on the back panel are set to position “ON”. Using bridged
mono mode implies that A and B (2 Ch.) or A and B, C and D
(4 Ch.) are running with the same input signal, but with inverted
phases. For output power values refer to technical specifications
on paragraph 7.
For bridged mono usage a single input is required for 2 Ch. am-
plifiers (Ch A or Ch B), whereas for 4 Ch. models Ch C or Ch
D can be selected also, paying particular attention that level at-
tenuators are set to the same position (we recommend position 0
dB). To connect the signal connectors Combo© can be used. The
loudspeakers should be linked to the selected output connector
speakon (refer to fig. 6).

• Parallel inputs (Link)
The parallel mode is enabled when the Link switches are set to
position “ON”. In parallel mode, the inputs of both channels are
connected and receive the same signal. The input signal should
be connected to Ch A or Ch B for 2 Ch. amplifiers, and also Ch
C or Ch D for 4 Ch. units. Both input connectors Combo© can be
used. Level attenuators work independently, it is therefore possible
to set a different level for every channel. The loudspeakers are linked
to the speakon output connectors A and B (2 Ch. - see fig. 7 a) or A
and B, C and D (4 Ch. - see fig. 7 b)
Please make sure that only the inputs are connected in parallel. Nev-
er connect the positive output terminals on earth or parallel.
Warning: always unplug the Link switches when running
the amplifier for Bi-amping.

6. Output stage block diagram
fig. 8 Output stage block diagram - XTDT amplifiers
The figure above shows a block diagram displaying the output
stage of XTDT amplifiers (Class D).
XTDT digital amplifiers are provided with a PWM-based techno-
logy (Pulse Width Modulation) i.e. the input signal is converted
into a pulse sequence whose output values are higher than the
input ones. Over the time, the average pulse width values will be
directly proportional to the one-point amplitude of the input signal.
The output pulse frequency is typically 10 or more steps higher
than the one-point amplitude of the input signal. A low-pass filter
(LPF) removes the undesired signal components from the modu-
lation spectrum and yields an output signal corresponding to an
accurately amplified version of the input one.

7. Protection features
All professional X-Treme amplifiers are equipped with strong pro-
tection systems to safeguard the amplifier and its load. These pro-
tection systems ensure the power amplifier a long operating life.
7.1 Limiter
When the limiter is ON the CLIP/LIM LED lights up. With the limiter
action the channel gain will automatically lower to protect the load
(loudspeaker systems) from damage caused by signal distortion.
It is not possible to disable the limiter circuit.
7.2 Thermal protection
The temperature state of the dissipator is constantly checked, the
HI-Temp LED gives indications on the temperature status. The Hi-
Temp starts flashing if the dissipater reaches a temperature of 60º
C. In such case the input signal of the relevant channel will be
automatically decreased until the correct running temperature is
reached. If the Hi-Temp LED stops flashing and the light remains
on (anomalous working condition) the whole system will go to
mute until the temperature reaches normal levels.
7.3 Power safety check
On X-Treme amplifiers the output current is constantly checked as
well as the input signal condition. If the current exceeds the maxi-
mum allowed level, output tension will be automatically readjusted
in order to assure the amplifiers safety status.
Power safety control acts especially in case of connection to a
load with impedance lower than the recommended levels or if at
the amplifier’s output a non acoustic signal is released during long
periods of time.
7.4 DC protection
If a value higher than or equal to 7 V occurs, the presence of a DC
on both channels will be monitored indipendently, and the ampli-
fier output stage and the switching supply will be blocked. This
allows loudspeaker protection from the DC.
7.5 Absorption limitation
The X-Treme power amplifiers are equipped with a soft-start sys-
tem to reduce the absorption when switched on. This feature is
particularly useful in multiple amplifier installations.
7.6 Power supply protection
The AC voltage is monitored; if its value does not fall within the
correct running range (over or under voltage) the supply will be
automatically blocked. The amplifier will restart when the main
supply voltage exceeds the minimum running tension or is under
the maximum running voltage.
7.7 Switch-on/turn-off transients
A mute circuit (without relay), with a delayed starting up and im-
mediate power turning off, has been introduced in order to avoid
the switch-on/turn-off transients that may cause damage to the
loudspeakers.
7.8 Maintenance information
Please contact the nearest X-Treme Assistance Service (Distribu-
tor or Dealer) or directly X-Treme Audio for maintenance assist-
ance.

* The amplifier will be fully operational at 2 Ohm loads (or bridge mode at 4 Ohm), but, due to physical constraints, the hi-temp protection may occur, limiting the maximum
