2. Installation Instructions
2.1. Mechanical Installations
The 44TDAP Series Amplifier system is designed to be mounted in a standard 19″
rack enclosure.
Where the amplifier is used in a fixed 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 fitting it in a standard rack
enclosure. If the amplifier 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 insufficient support is not covered by the warranty.
To prevent damage to the front panel it is recommended that plastic cups or washers are fitted underneath the rack mounting bolt heads.
It is possible to mount multiple 44TDAP Series amplifiers without ventilation gaps between them, but it is essential that an unobstructed flow of clean air is available from the front of the unit to the rear (cooling mode of the 44TDA Amplifiers, 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 amplifier from the back of the rack to the front.
The amplifier 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 environment before
connecting the AC power cord.
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
amplifier. Damage so caused is not covered by the manufacturer’s warranty.
2.2. AC Power Connection
The amplifier is fitted 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)
⚠ CAUTION: If you are not 100% confident of your competence to replace the mains plug, engage qualified personnel to do the job
The amplifiers are designed to operate on 50/60 Hz AC power (±10%). The power supply sections automatically configure themselves for either 115V or 230V nominal voltage at turn on. The amplifiers will operate over an extended range of supply voltages (please refer to the technical specifications). The threshold of these ranges are: [115V range = 100-126Vrms]; [230V range = 207 – 253Vrms].
Note that whilst the amplifier will operate correctly at voltages indicated, the specified 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, – orout 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 performance and regulations are met.
2.3.2. Using unbalanced connection
Please note that the use of unbalanced connections is not recommended, however, when connecting the amplifier 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.
2.3.3. Amplifier Output Connections
The 44TDAP amplifiers are fitter with one SpeakONTM NL4 connector per amplifier channel. The appropriate conductor terminations are shown below and on the rear panel of the unit.
Additionally, the SpeakONTM NL4 connector for amplifier channel 1 carries the output for amplifier channels 1 and 2. Similarly, the SpeakONTM NL4 connector for amplifier channel 3 carries the output for amplifier channels 3 and 4. This can be useful for making a connection to two loudspeakers with one 4-core cable (i.e. Bi-amp).
In addition, the channel 1 or channel 3 connector can also be used if the pair of amplifier 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 amplifiers 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 shutdowns. 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.
⚠ CAUTION: ever attempt to reverse the airflow
⚠ Make sure an adequate air supply is provided in front of the 44TDAP, and
that the rear of the 44TDAP has sufficient 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 significant negative impact
on the expected lifetime on the components inside the 44TDAP.
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 amplifier 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 effect is not enough, please turn off 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.
3. Technologies and Key features
3.1. Introduction
The 44TDAP DSP amplifier systems integrate light-weight power supplies, high power sonically transparent class-D amplifiers, 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, adopting 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 amplifier with a 90% efficiency and an incomparable stability.
All 44TDAP Series amplifiers 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 amplifier 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 filtering with 512 taps, bringing linear phase response to the Tecnare presets.
