2 MAIN FEATURES
The Xamp3K amplifier is modular in design. The rigid metal chassis provides easy
access to the electronic circuits. Fully independent safety circuits protect the
amplifier in the event of a short circuit of the loudspeaker output, abnormal increases
in temperature and/or excessive amplifier consumption.
The Xamp3K amplifier offers high dynamic performance with moderate average
energy consumption, as well as good damping factor, which results in clean
response to transients and high quality playback.
The power modules are integrated in a tunnel-shaped own developed heat sink,
which combines high dissipation power with an excellent thermal inertia, thanks to
the high extraction effectiveness of the incorporated fans.
Other features include:
- Separate input XLR, electronically balanced for each way (Low & High)
- Volume control, limiter and indicators VU for each way (channel)
- Output for both ways via one single 4-pole Speakon, with an additional LINK
Speakon (PARALLEL). Independent binding posts may be also used.

4 INSTALLATION
4.1 Connection to the mains
First, it is essential to ensure that the main voltage corresponds to the apparatus
voltage. It is not advisable to connect and disconnect the mains wire without first
making sure that the switch is in its OFF position. The amplifier is equipped with an
Inrush current limiter circuit, which avoids current excess when powering up. In
addition to that, a breaker switch located close to the IEC socket protects the
amplifier when the average current consumption is out of the specified range.

WARNING: the connection to any other voltage different from the one
specified can damage the amplifier immediately.
4.2 Connection of the loudspeakers
The loudspeaker system should be connected to the Speakon or binding posts
connectors ensuring that the polarity is correct. It is very important to use a cable
fitting to the power of the amplifier in order to maintain the high damping factor these
units provide.
As a general guideline, we offer a table showing the recommended cable section for
different cable length, in order to keep power and damping factor loss in acceptable
values.

WARNING: high risk of malfunction or major damag e!
As specified in the previous point, there is the possibility to use
simultaneously the different outputs, such as OUT SPEAKON, LINK
SPEAKON and the Binding Posts. Please make sure to check that the
total load connected to each channel is not below 4 Ohm, since all outputs are
connected in parallel.
Be extremely careful when performing the connections, as a short-circuit between
any of the positive pins (+1, +2) can damage the amplifier or even cause the
destruction of one or both power modules.
4.3 Connection of the inputs/auxiliary outputs
The inputs (BALANCED INPUTS) enable connection through XLR-3 connectors. The
amplifier incorporates balanced inputs for a high rejection of noise generated by long
signal cables, proximity to electric wires or sources causing them.
BALANCED Inputs/auxiliary outputs:
1. Shield
2. (+) Live
3. (–) Return
UNBALANCED Inputs/auxiliary outputs:
1. Not connected (* See Note)
2. (+) Live
3. Ground

(*) NOTE: This amplifier follows the ground interconnection specification defined by
AES48-2005 standard of the Audio Engineering Society, on grounding and EMC
practices for audio equipment containing active circuitry. For that reason, when a
source with unbalanced outputs should be connected, it is recommended not
to use Pin1 of the XLR, and never connect it to Pin3. If a shielded cable is
available, the shield may be connected to Pin1 of the XLR to get some shielding,
leaving the other end unconnected. Pin1 connection is only advised if the equipment
with the unbalanced output has a dedicated connection for the shield, separate from
the audio signal ground reference.
Before powering up the unit, make sure that the input and output XLR cables are in
good state and following the above described pinning diagram, as defined by the
AES14 standard.
When connecting the XLR, please decrease the amplifier volume to the minimum
with front volume knobs until you configure the signal processing. Loudspeakers may
be damaged due to a wrong setup. It is advisable to first raise the volume of the high
frequency channels: in case they are connected to low frequency drivers by mistake,
they cannot be damaged. Otherwise, high frequency speakers may be damaged
because of trying to reproduce low frequencies. Then raise gradually the volume and
check that the system is properly connected. If so, proceed to increase the volumes
to its maximum position.
5 OPERATING THE AMPLIFIER
Along with this equipment it is necessary to use an external processing unit, for
example the DSP608, which provides to each channel the required processing to
control systems requiring independent settings for low and high (Bi-amplified).
This amplifier is designed to drive loads between 4 and 16 Ohms.
5.1 Start-up
Once the mains, loudspeaker and sound sources (input) connections have been
made correctly, start up the pre-amp sources and then press the ON/OFF switch.
Turn the volume controls clockwise to obtain the maximum gain. The amplifier is
equipped with a Soft Start circuit, which assures a gentle, pop free start up, avoiding
stress to the loudspeakers.
In order to obtain the maximum dynamic range from the amplifier, it is recommended
to set always the gain controls to the maximum, and control the output power by
regulating the signal level at the amplifier’s input using the processor gain control (in
this condition of the gain controls to the maximum, the amplification is fixed at 32dB
per channel).
5.2 Clip/Limiter
This circuit prevents the amplifier from delivering distortion at the loudspeaker
outputs. Its action is practically inaudible and protects the loudspeaker voice coils.

Xamp3K May 2016
10 Amate Audio
A LED on the front panel indicates the action of the anti-clipping limiter of each
channel. If the clip LED is lit intermittently, this may be interpreted as correct, but it
means that the amplifier is reaching its maximum power at this point.
Fig. 5. Limiter leds location on the front panel
WARNING: Make sure the LED LIMITER is not alight permanently!
No extra power is obtained in this way, losing dynamics and sound
quality.
5.3 Limiter adjustment
The amplifiers Xamp3K feature a limiter adjustment, in which the user, with an easy
adjust, can limit the output power of each output independently. Along with the DSP
input level controls and/or an external limiter, the use of this adjustment can be very
useful to protect the system in case of connection errors in XLR input or outputs
It is an easy access adjustment and it is located behind the front panel. The front
panel is fixed with two M4 screws with knurled head that can be loosen with the
fingertips. After removing the front panel you will find two LIMITER sections, one per
channel, they can be adjusted with a small flat-tip screwdriver.
Fig. 6. Limiter adjust potentiomenters on the internal front panel
The factory setting for this parameter is set to fully clockwise; this way the device
delivers its maximum power with minimum distortion thanks to its anti-clipping
system.
Each channel has an independent limiter adjustment; see the attached table of the
delivered output depending of the limiter adjustment:

Table 3. Maximum output power delivery depending on limiter adjust
NOTE: The limiter adjustments and power that the amplifiers can deliver with this
adjustment are relative, because the Xamp3K amplifiers feature a dynamic limiting
system able to offers the best results.
The conditions to obtain the data in the tables have been created using 100 Hz sine
burst input signals with 100 ms at 0 dB and 400 ms at -20 dB. This condition is
considered as a standard / heavy duty in the Audio Industry.
5.4 Cooling
The Xamp3K is equipped with electronically controlled forced ventilation, which is
carried out by two turbines situated at the rear panel, one in front of each power
module. According to the temperature, two different fan speeds are set, and the hot
air is evacuated through the front panel. It is very important to favour the good air
circulation to keep the equipment in a stable temperature work pattern; therefore any
possible obstruction must be avoided both in the rear and front part. In addition, an
installation close to heat generator sources or lack of ventilation must be avoided
(closed cabinets).
WARNING: As the forced air circulation (from the back to the front) can
produce the introduction of dust and dirt in general over the internal
radiators, it is highly recommended to make an internal cleaning
operation at least once a year, depending on the particular
circumstances of each installation or use.
Any deterioration of the amplifier caused by an evident presence of dust and/or
internal humidity, will EXCLUDE of any right of application of the warranty for this
product.
5.5 Protections
Temperature
An inadequate installation or any other anomaly related to cooling may cause that
the amplifier’s temperature exceeds their safe limit (>90ºC), exposing its internal
components to failure. The temperature protection would activate the corresponding
limiters to reduce (balance) the output power with the over-temperature, in order to

Xamp3K May 2016
12 Amate Audio
keep the amplifier working safely without undesirable stops. In case the temperature
keeps rising, the corresponding protection circuit will cause a stop during a certain
time according to the seriousness of the anomaly detected. The PROTECTION and
LIMITER leds will light on at the same time, and the output of the affected channel(s)
will be disconnected.
In LOW channel, before the amplifier completely stops because of temperature
problems, it will reduce the output level by 6dB approximately. Once the temperature
reduces to normal parameters, the normal output level will be re-established.
Short circuit
In case of very low impedance or short circuit in any loudspeaker output, the
LIMITER led is activated and a significant descent of the output level of the affected
channel will be observed (loss of volume, but keeps working)
Direct Current
In the case that due to some malfunction the power module tries to deliver direct
current (DC) at the output, the protection circuit will immediately disconnect the
module to avoid damage to the loudspeakers. In that case, the PROTECTION and
LIMITER leds will light on at the same time and the output will be disconnected
Other causes that could prevent the normal work of the amplifier can also activate
the PROTECTION. Under those circumstances, the installation has to be revised
according to the basic principles described below:
• Disconnect all the connected peripheral equipment (sources, pre-amplifiers,
and loudspeakers). Leave the amplifier “alone” and verify if the anomaly
disappears or if it remains in only one channel or both.
• Temperature: Cooling (possible air obstruction. Check if the fans are working
and make an internal cleaning).
• Short circuit: Check the state of the loudspeaker line (possible short circuit,
disconnect and check if the anomaly disappears).
• C.C. at the output (DC): Possible serious breakdown. Contact an authorized
technical service.
In all cases it is recommended to go through all previous checkpoints before
contacting the authorized technical service and reporting the observed problem.
