2. Installation Instructions
2.1. Mechanical Installations
The 44TDAP Series Amplier system is designed to be mounted in a standard 19” rack enclosure.
Where the amplier is used in a xed installation, as long as the bottom unit is supported and there
are no gaps between units, it is acceptable to use only the front panel 19” rack holes when tting it in a standard
rack enclosure. If the amplier is mounted in a mobile rack it is important that the rear is supported with a rear rack
mounting kit (part number TDK-TS). Damage caused by insu󰀩cient support is not covered by the warranty.
To prevent damage to the front panel it is recommended that plastic cups or washers are tted under-
neath the rack mounting bolt heads.
It is possible to mount multiple 44TDAP Series ampliers without ventilation gaps between them, but
it is essential that an unobstructed ow of clean air is available from the front of the unit to the rear (cooling mode of
the 44TDA Ampliers, Also see “2.4. Cooling” on Page 15). It is important that neither the air intakes on the front of
the unit or the exhaust vents at the rear are covered. Steps must be taken to ensure that hot air does not continually
circulate through the amplier from the back of the rack to the front.
The amplier should never be exposed to rain or moisture during operation or storage. If the unit does
come into contact with moisture, disconnect the AC power cord immediately and leave it in a dry and warm location
to dry out.

Note that when any equipment is taken from a cold location into a hot humid one, condensation may
occur inside the device. Always allow time for the equipment to attain the same temperature as its surrounding envi-
ronment before connecting the AC power cord.
2.2. AC Power Connection
The amplier is tted with a 3 x 2.5mm² power cord and a 3-pin Shucko (CEE 7/7) power connector.
If the power plug mounted at the factory is not appropriate for your country, it can be removed and
the proper connector wired in its place as follows:
BLACK or BROWN LIVE
WHITE or BLUE NEUTRAL
GREEN or GREEN&YELLOW EARTH (GROUND)
The ampliers are designed to operate on 50/60 Hz AC power (±10%). The power supply sections
automatically congure themselves for either 115V or 230V nominal voltage at turn on. The ampliers will operate
over an extended range of supply voltages (please refer to the technical specications). The threshold of these rang-
es are: [115V range = 100-126Vrms]; [230V range = 207 - 253Vrms].
Note that whilst the amplier will operate correctly at voltages indicated, the specied output power
will only be achieved when operating with the stated nominal voltages.
2.3. Audio Connections
2.3.1. Input connections
For each input channel there is a female XLR-3 connector for analogue inputs. The 44TDA Series
can be fed with up to four balanced analogue audio signals.
The HOT, + or ‘in phase’ connection should be made to pin 2 of the XLR connector.
The COLD, - or ‘out of phase’ connection should be made to pin 3 of the XLR connector.
Pin 1 of the XLR connectors is internally connected to the chassis.
The shield of the input cable should always be connected Pin 1 of the XLR to ensure the EMC per-
formance and regulations are met.
Fig. 02: PIN out assignment 44TDAP Series Analogue Input/Link - Balanced connection
CAUTION: If you are not 100% condent of your competence to replace the mains plug,
engage qualied personnel to do the job
IMPORTANT: It is the responsibility of the user to ensure that dirt, liquids and vapour from
theatrical smoke and fog machines is not ingested by the amplier. Damage so caused is not
covered by the manufacturer’s warranty.

2.3.2. Using unbalanced connection
Please note that the use of unbalanced connections is not recommended, however, when connect-
ing the amplier to an unbalanced audio source, the signal conductor should be connected to XLR pin2. The ‘Cold’
conductor or cable screen should be connected to XLR pin 1 with a short connection made between pin 1 and pin3
as shown in Figure 03.
Fig. 03: Balanced to Unbalanced Analogue wiring and PIN out.
2.3.3. Amplier Output Connections
The 44TDAP ampliers are tter with one SpeakON™ NL4 connector per amplier channel. The
appropriate conductor terminations are shown below and on the rear panel of the unit.
Fig. 04 Amplier output connections - TDA Series
Additionally, the SpeakON™ NL4 connector for amplier channel 1 carries the output for amplier
channels 1 and 2. Similarly, the SpeakON™ NL4 connector for amplier channel 3 carries the output for amplier
channels 3 and 4. This can be useful for making a connection to two loudspeakers with one 4-core cable (i.e. Bi-amp).
Fig. 05 Amplier Output Bi-amp connexion (CH1) - TDA Series
In addition, the channel 1 or channel 3 connector can also be used if the pair of amplier channels is
being operated in bridged mode. It must be done, using the connection pin: 1+/2-

2.3.4. Load Matching
Each output of the device can be optimised to drive either a low-impedance load (e.g. 2, 4 or 8
Ohms). The 44TDAP Series ampliers have adequate current capability to fully drive loads up to two ohms, however,
many high-performance “8-ohm” loudspeakers, especially multi-way systems with passive crossover network, have
impedances at some frequencies which are far lower than the average rating. An impedance minimum of 2 ohms or
less is not uncommon. For this reason, speaker impedance curves should be consulted before connecting speaker
in parallel.
The 44TDAP Series amps will do an outstanding job with any 8-ohm, full-range loudspeaker system,
and we expect equally outstanding performance when driving 4-ohm load. The 2-ohm load should be approached
with caution, as there is not further margin for impedance dips. The amp should not be damaged, but high-power
operation into reactive 2-ohm loads may result in overheating or excessive AC current consumption, causing shut-
downs. In addition, some power may be lost at those frequencies where the impedance dips below 2 ohms. For these
reason the operation with 2-ohm load should be tested thoroughly before putting into use.
2.4. Cooling
The 44TDAP Series devices use a force-air cooling system as follow: the cold air is sucked through
the ventilation hole of the front panel, and the heat is taken out from the rear panel. It allows high continuous power
levels without thermal problems.
2.4.1. Temperature Sensing and Protection
The 44TDAP is equipped with a sophisticated temperature sensing system which protects it from
any overheating which may occur as a result of inadequate ventilation. If the temperature exceeds 85 degrees, the
output voltage will be reduced, avoiding an excessive temperature rise. If the temperature continues to increase up
to 90 degrees, the power amplier will be shunted down. Once the temperature has fallen to a safe temperature, the
equipment will reboot automatically. After working for a while, if the cooling e󰀨ect is not enough, please turn o󰀨 the
equipment and remove the dust net cover to clean up the dust. If even doing this, the device still unable to recover
on its own, please contact our support team.
CAUTION: ever attempt to reverse the airow
Make sure an adequate air supply is provided in front of the 44TDAP, and that the
rear of the 44TDAP has su󰀩cient space to allow air to escape. If the 44TDAP is
rack-mounted, never operate the unit with any front or rear rack doors or covers
in position. It is recommended to keep the ambient temperature in the 0º~45ºC
(32º~113ºF). An increased temperature can have a signicant negative impact on
the expected lifetime on the components inside the 44TDAP.

44TDAP Series
3. Technologies and Key features
3.1. Introduction
The 44TDAP DSP amplier systems integrate light-weight power supplies, high power sonically
transparent class-D ampliers, complete system monitoring and a fully featured ETHERNET network controlled 32
bit / 48kHz DSP processing platform,handled by the front panel dual Rj45 connectors, as standard.
44TDAP Series have been engineered for mid sized venues, rental and touring applications, adopt-
ing circuit architecture of multi-loop control technology, bearing-up constant resistance output and developed for
low-impedance and high-current, as a result we obtain a power amplier with a 90% e󰀩ciency and an incomparable
stability.
All 44TDAP Series ampliers come with built-in active Power Factor Correction and soft switching
technology. It can ensures that a predominantly resistive load is presented to mains thus minimizing current distortion
and voltage/current displacement. This leads to improved performance of the amplier at high levels of output and
avoids mains-voltage collapses, typical of standard and switching power supplies. Another great advantage of this
technology is that its performance is, to a large extent, independent of mains voltage. The rated output power does
not vary with load/line conditions.
The advanced 48kHz DSP is fully integrated into the product and provides an amount of useful
features. Its powerful Limiter suite provides Peak and RMS limiting, as well as multi-band limiting for passive 2-way
enclosures. Many convenient features are provided as Gain, delay, EQ and a powerful FIR ltering with 512 taps,
bringing linear phase response to the Tecnare presets.
3.2. Main Features
• High eciency, energy-saving and emission-reduction
• Small size, light weight, 1U rack space
• Active Power Factor Correction (APFC)
• High reliability, meeting the requirements for high-quality audio system and engineering products
• Low noise of the power amplier and the mute fan
• 4-channels models

3.3. Preset Manager
The 44TDAP Series amplier preset manager focusing to give a more speaker-based approach to
controlling, designing and recalling speaker congurations.
The Device Preset module, provides access to a full device preset of the device. The Speaker cong
module gives access to only one output channel block.
3.4. FIR Filtering
The advantages of FIR ltering include more arbitrary and ne control of a lter’s magnitude and
phase characteristics, independent control of magnitude, very long minimum-phase FIR based system EQ, horn
correction ltering, independent control of magnitude and phase, and mixed & maximum-phase characteristics.

4.1.1. The Front Panel Layout
The front panel of the Device 44TDAP Series ampliers is a combination of button together with the
LCD display allows the user access to detailed information and control over the amplier’s status. This chapter illus-
trates all the functions and settings accessible via the amplier front panel.
All the setup and setting functions described in this chapter can be also accessed via computer with
PCC-NET software.
1. Ethernet Communication Port
The amplier may be controlled entirely from another controller, typically a Personal Computer, running
Tecnare PCC-NET software. Connection will normally be made to the controller via this Ethernet port
connector with shielded Cat-5e cables. This port is also used for updating the rmware in the unit. The
port is dual Rj45 built-in switch chip.
2. LCD Graphical Display
When the device is switched on, it will show on the default screen. It will have access to a ve setting
submenu. The screen contrast can be changed by pressing the encoder button to navigate to <Setting>
and using the encoder got to “Contrast” and using also the encoders to change the percentage; this can
also optimise the viewing angle.
3. Parameter Encoders
A velocity sensitive parameter encoder is used to adjust parameters shown on the display.
4. Power Switch
Applies mains power to the device.
5. Cooling vents
These opening force airow from front to back through the air lter.

5. Quick Start
The 44TDAP Series amplier are not only powerful ampliers but, have a comprehensive processing ability,
allowing great systems as your design required. All you need to do is recall the appropriate Preset, connect your speakers and
source and away you go. This section shows you how to achieve the quickest, most straightforward set up using an 44TDAP5.0.
5.1. Loading a 2-way (Bi-amp) Preset
1. Connect the amplier. The 44TDAP requires mains connected to its main power and an input feed
signal, balanced analogue to the input XLRs. A 2-way loudspeaker run in bi-amp mode can be connect-
ed directly to output SpeakON® 1 and 3 as these also have channels 2 and 4 respectively connected
to pins 2± specically for bi-amp operations. See the chapters on mains, input and output connections
for more details.
2. Power up the amplier, once it has completed its power-up cycle the home screen will show.
3. Press one time the encoder button to access to preset menu.
4. Using the encoder control to scroll round to the required preset 2-way preset, e.g. Flat
5. Press one time again the encoder button and them the LCD will be displayed “Recall the data,
sure?”.
If you press “NO” you will come back to the preset menu. If you press “YES”, now the amplier will be
set with your desired preset.

In the preset page, current is the currently loaded preset. The next lines show the available presets
contain into the device. A total of 16 preset can be stored. The device may contain a library of Factory Presets de-
signed to suit Tecnare loudspeakers.
Factory Presets may contain some parameters that are xed and hidden from view; the remainder
of the parameters are available for user manipulation. Typically crossover frequencies, output delay and some EQs
are hidden; those settings that are a function of the loudspeaker cabinet design and should not require adjustment
for di󰀨erent applications.
