2 MAIN FEATURES
2.1 Amplifier features
The TPD3K amplifier is modular in design. The rigid metal chassis provides easy
access to the electronic circuits. 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 TPD3K amplifier offers high dynamic performance with extremely good
efficiency, as well as good damping factor, which results in clean response to
transients and high quality playback.
The power modules are integrated in a H-shaped own developed heat sink, which
combines high dissipation power with an excellent thermal inertia, thanks to the high
extraction effectiveness of the incorporated fan.

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.
AC 85/240V –50/60Hz
Average current draw @230V: 1.5 A Musical Program
5 A Heavy Duty
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 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 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 shortcircuit between any
of the “live” pins (see Table 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 and auxiliary outputs 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.
The auxiliary outputs enable the interconnection of other amplifiers to the TPD3K
internal processor, which enables 3 independent processing channels.

(*) 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 mute the outputs with the front panel switches
until you configure the signal processing. Loudspeakers may be damaged due to a
wrong setup. It is advisable unmute first the L and R channels: in case they are
connected to a subwoofer driver channel by mistake, it cannot be damaged.
Otherwise, high frequency speakers may be damaged because of trying to
reproduce low frequencies. When the L and R channels are properly connected,
proceed to unmute the subwoofer channel.
5 OPERATING THE AMPLIFIER
5.1 Start-up and operation
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 on

the rear panel. The amplifier is equipped with a Soft Start circuit, which assures a
gentle, pop free start up, avoiding stress to the loudspeakers.
After powering up the unit, all LEDs will be lit for about six seconds, while the
following message is displayed on the LCD:
After that, the DSP unit displays its main screen:
Now the unit is ready to operate. The screen shows the name of the unit (above line)
and the program name currently active (below line). The program assigned is always
the last program the user recalled or stored before powering down the unit. The first
user program is number 31 and programs 1-30 are the factory presets.
An admiration mark (!) beside the program name means that the program has been
modified but not stored. Read-only presets (1-30) can be only saved as new presets
in the free user slots (31-100). See Table 3.
WARNING: when no signal is present at the input, the amplifier will
power up in eco mode (Led Eco on). After signal is applied, the normal
operation will start. See section 5.4 for more details.
5.2 DSP Preset selection
In order to properly distribute the frequencies to the different channels, the DSP must
be configured first. To ease this process the TPD3K has built-in presets for the most
common applications, using Amate Audio loudspeakers or generic loudspeakers.
Preset 1 to 10: Generic presets (read-only).
•Provide a template for the most common applications using generic
loudspeakers (i.e Xo100+SW4Ohms). The subwoofer channel is configured
with a Low Pass filter of 80, 90, 100, 110 or 120 Hz, and a clip limiter
depending if the load is 4 Ohms or 8 Ohms. The L/R channel is configured
with a HPF also in the range of 80, 90, 100, 110 or 120 Hz. The limiters are
set to the maximum power that can be delivered by the amplifier.
•The user can modify the inputs and the outputs, but they cannot be
overwritten.

WARNING: Make sure that you select a preset that matches the load
impedance of the subwoofers. If the total load of the channel is 4 Ohm
select a “4 Ohm load” preset. If the load is 8Ohm, select “8 Ohm load”.
Default presets are optimized for a 4 Ohm load.

TPD3K Jul 2021
12 Amate Audio
5.3 System Optimization
The built-in presets of the TPD3K have been adjusted to obtain the maximum
dynamic range from the amplifier. It is recommended to control the output power by
regulating the signal level at the amplifier’s input (using the corresponding gain
control of your sound source).
When the maximum output power has been reached in any of the channels, this will
be indicated by the corresponding led LIMITER, advising that it is recommended to
lower the general volume coming from the mixer our sound source connected to that
channel.
5.4 Standby and Eco mode
The Eco Mode is a built-in function intended to save energy costs when the amplifier
is idle. When this mode is active, the green led “Eco” will be lit and the power supply
enters a low power consumption mode. In EcoMode, the DSP remains on and it can
be still operated.
The amplifier will go automatically into Eco Mode under two conditions:
•After 3 minutes without presence of signal at the audio input.
•When the amplifier is powered up (by activating the rear switch, pushing the
standby button or applying AC at the input) it will automatically set the
EcoMode if at this time no signal is present at the input.
As soon as signal is detected again, the amplifier will switch on again. During the
power up process, the led PROTECT (red) will light, and output will be delivered
after 8 seconds.
The Standby function allows the user to quickly switch off the amplifier from the front
panel. When in Standby, the power supply is switched off and the DSP will be set in
idle.
When pressing the standby button, it will change its colour to red. To set the
amplifier in normal working mode, press again the button (it will be change again to
white colour). During the power up process, the led PROTECT (red) will light, and
output will be delivered after a few seconds.
5.5 Cooling
The TPD3K is equipped with electronically controlled forced ventilation, which is
carried out by a turbine situated at the rear panel. 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

TPD3K Jul 2021
13 Amate Audio
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.
5.6 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
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 PROTECT led will
light on and the output of the affected channel(s) will be disconnected.
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
PROTECTION led is activated and the output will be disconnected.
Direct Current
In the case that due to some malfunction the power module tries to de- liver direct
current (DC) at the output, the protection circuit will immediately disconnect the
module to avoid damage to the loudspeakers. In that case, the PROTECT led will
light on and the output will be disconnected.
Other causes that could prevent the normal work of the amplifier can also activate
the PROTECT. 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 fan is 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.

TPD3K Jul 2021
14 Amate Audio
•In all cases it is recommended to go through all previous checkpoints before
contacting the authorized technical service and reporting the observed
problem

6.2.5 Dynamics Compressor [only in Admin mode]
A true RMS compressor can be set to avoid the input signal go above a certain RMS
value. The following parameters can be adjusted:
• Thr. - Compressor Threshold. Sets the level at which the compressor will activate.
• Att. - Attack time. Time it takes the compressor to start actuating after reaching the
threshold.
• Hold - Hold time. Sets up a delay before the compressor enters the release cycle.
Useful for compressing low frequency long notes.
• Rel. - Release time. Time the compressor uses to return to unity gain after the
signal is below the threshold.
• Ratio - The compressor ratio determines the slope in which the signal is
compressed. The higher this value is, the higher the compression.
• Gain –The compressor make up Gain. Use it in case the level of the compressed
signal must be corrected (0dB by default)
6.2.6 Limiter
A peak-limiter can be set at each input. It is a zero attack time limiter, so it will
immediately act on the signal. The parameters that can be changed are:
• Thr. –Threshold: input level at which the signal will be limited.
• Rel. –The release value, expressed in dB/seconds [only in Admin mode]
