T24N Operating Manual Operating Manual T24N Introduction Thank you for choosing a high quality product "MADE IN GERMANY" from TW AUDiO. The T24 was the first TW AUDiO loudspeaker and a benchmark for almost ten years for numerous users in the live and installations market. The innovative 2 × 12"/1.4" horn in horn construction enables an outstanding dynamic and 143 db top acoustic pressure with an enclosure front surface of just 70 × 40 cm. In 2014 a substantial upgrade followed with the T24N. Good just got better – and lighter. The specifically developed 12" neodymium chassis together with the new enclosure construction make the horn loaded loudspeaker full range capable just under 70 Hz. The new 1.4" mid high range driver with a 3" titanium membrane reproduces silky highs exact and free of distortion even on the highest levels. The standard fitted 60° × 40° horn can be, without the use of tools, exchanged for a 90° × 50° horn.

Safety | Intended use Please adhere to the following safety instructions to avoid risks when operating the loudspeakers. The T24N loudspeaker was developed for professional use in sound systems. The loudspeaker may only be used by trained and qualified personnel. Note the operating modes described in this operating manual. Other uses are not permissible. TW AUDiO shall not be liable for any damage that ensues from unintended use. Loudspeakers generate an electromagnetic field. Persons with pacemakers are not permitted to remain in the immediate vicinity of loudspeakers as the electromagnetic fields can cause pacemakers to malfunction. WARNING When working with heavy loads over 20 kg [44,09 lbs], use suitable aids (dollies, hoisting slings, etc.). Multiple people may be required depending on the situation. WARNING Ensure that the units are in a stable position and are firmly attached. A falling loudspeaker can result in serious personal injury and property damage. When using and assembling TW AUDiO loudspeakers, only use materials specified by TW AUDiO. These tasks must be performed by qualified personnel. Adhere to the applicable safety regulations. When using the loudspeakers, ensure that they are not exposed to the following ambient conditions: NOTE WARNING • Direct sunlight • Moisture • Jolting • Dust Keep away from the immediate vicinity of loudspeakers that are operated at high sound pressure levels. These loudspeaker systems are capable of endangering your health. Sound levels beginning as low as approx. 90 dB SPL can lead to long-term hearing impairment. Avoid: NOTE • Feedback • Distorted signals (clipping) • Peaks that result when devices are switched on or hot plugged and unplugged. These signals can result in overloading of the loudspeaker. 1 Operating Manual T24N Ensure that the loudspeaker is not exposed to permanent thermal overloads. This may cause a fire and result in serious personal injury and property damage. WARNING Note that TW AUDiO does not provide a warranty for damage that can be attributed to this type of overload and therefore cannot be held liable for any secondary damage. NOTE NOTE 2 A permanent, magnetic field is present in the immediate vicinity of loudspeakers. Ensure that objects which react sensitively to magnetic fields are not located in the immediate vicinity of the loudspeaker. In particular, this applies to magnetic data carriers, EC cards and CRT displays. A distance of approx. one meter is sufficient to avoid damage. Check loudspeakers and accessory parts regularly for visible wear. This is essential to ensure fault-free operation on a permanent basis. Replace worn parts promptly. Spare parts can be obtained from TW AUDiO. Operating Manual T24N 2. Overview 2.1 Components 1 2 3 4 (Integrate graphics) 7 8 13 14 9 5 10 13 11 15 12 6 Figure 2.1 - Overview 1.

The specified degree values refer to the horizontal and vertical radiation characteristics of the horn. Different interchangeable horn cones can be installed for this purpose. The variant of the T24N loudspeaker can be identified on the outside of the horn cone (see figure 2.2). 90° Figure 2.2 - Variants of the T24N horn cone The modular design of the high frequency unit allows a quick change between the different characteristics of dispersion. TIPP 4 3 2 The entire high frequency unit consists of the horn cone (1), the horn base (2), the driver plate (3) and the compression driver (4). 1 Figure 2.3 - High frequency unit 2.3 Operating modes The T24N loudspeaker has a switch (see figure 2.4) on the back for switching between two different operating modes (see figure 2.1, no. 10). In the "PASSIVE" mode, the loudspeaker is operated on a passive audio crossover with a single amplifier channel. In the "BIAMP" mode, the internal passive crossover is being by-passed, therefore the low-frequency section (2×12") and high-frequency (1×1,4") section must be driven separately by individual processed amplifier channels. Figure 2.4 Never change the operating mode while the loudspeaker is connected. In addition to setting the switch, the corresponding preset on the amplifier must be changed. NOTE 4 Operating with an incorrect preset can damage parts of the loudspeaker. Operating Manual T24N 3.

Setting up the loudspeaker 4.1 Setup WARNING Ensure that the loudspeakers are in a stable position to prevent personal injury and property damage. Secure stacked loudspeakers properly so that they can be tipped by 10° in any direction without toppling. Ensure that no thoroughfares are crossed when laying loudspeaker cables. Use cable protectors or similar if necessary. TW AUDiO recommends using only the accessories specified by TW AUDiO to secure the loudspeakers. NOTE The T24N loudspeaker is designed for upright operation. A variety of accessories is available from TW AUDiO to securely attach the loudspeaker, e.g. on stands or suspended from trusses and motor lifts. Horizontal operation is not an intended use. 4.2 Rotating the horn and exchanging the horn cone The horn of the T24N loudspeaker is positioned such that the horizontal coverage is 60° and the vertical coverage is 40°. In some situations, it may be advantageous to change the output characteristics of the high-frequency range. For this purpose, you can rotate the horn together with driver or exchange the horn itself into 90° × 50° variant. Proceed as follows. 4.2.1 Rotating the horn 1. Place the T24N loudspeaker on the back side with front grill facing up. Ensure that you work on a clean and non-slip surface. 2. To remove the front grill of the loudspeaker, use a 3-mm hex key. Remove the four screws on the top and bottom of the loudspeaker enclosure (two on each side). 3. Pull the horn cone up and out of the horn base. 4. Unplug the black connector from the enclosure. 5. Release the fixing screws of the horn base. 6. Rotate the horn base by 90°. Ensure that you hold onto it firmly at all times. This will prevent damage to the woofer membrane. ow tighten the horn base again. For this purpose, use a 6-Nm torque wrench. 7. Plug the black connector back in. Ensure that the cable connection of the driver does not touch the membrane of the woofer. Otherwise, this component could be damaged. 8. Insert the horn cone back in the horn base. To do so, firmly push the horn cone to enable the catch mechanism to engage in the horn base. Then check that the horn cone is firmly seated in the horn base. 9. Screw the front grill back on hand-tight. NOTE NOTE 6 Operating Manual T24N 4.2.2 Exchanging the horn cone 1. Place the T24N loudspeaker on the back side with front grill facing up. Ensure that you work on a clean and non-slip surface. 2. To remove the front grill of the loudspeaker, use a 3-mm hex key. Remove the four fixing screws on the top and bottom of the loudspeaker housing. 3. Pull the horn cone up and out of the horn base. 4. Insert the other horn cone back in the horn base. To do so, firmly push the horn cone to enable the catch mechanism to engage in the horn base. Then check that the horn cone is firmly seated in the horn base. 5. Screw the front grill back on hand-tight. 4.3 Connecting cables To create a cable connection with an amplifier rack from TW AUDiO, proceed as follows. NOTE Ensure that the cable cross section is sufficiently large (at least 2.5 mm²) to avoid power losses. TW AUDiO recommends using the loudspeaker cables available from TW AUDiO. Ensure that the polarity (+/-) and pin connection (1/2) of the cables are correct. An error here will result in a significant change in the loudspeaker sound characteristics and may damage the compression driver. The connection assignment of the T24N loudspeaker can be found in section 3.2 "Wiring diagram" on page 5. The two speakON NL4 connectors on the back side of T24N allows to link multiple T24Ns on a single amplifier output. Note that parallel connection reduces the total impedance seen by the amplifier. The total impedance of loudspeakers connected in parallel must not drop below the minimum operating impedance of the amplifier. 4.4 Operation A T24N loudspeaker can only be operated with a DSP controller. TW AUDiO only recommends using presets developed by TW AUDiO. The TW AUDiO system racks are ideal for this purpose. Ensure that the preset that matches the chosen operating mode (see section 2.3) is recalled before connecting the loudspeaker to the amplifier. NOTE Operating with an incorrect preset can damage parts of loudspeaker. Ensure that the amplifier is properly sized according to requirements. Undersizing or oversizing may damage the loudspeaker. NOTE Please note the technical data in section 3.1. 7 Operating Manual T24N 5. Transport and storage Because the T24N loudspeaker weighs over 20 kg [44,09 lbs], two people are needed to move and transport the unit. The FDB30 front dolly and the Twin Case can be used to transport the T24N loudspeaker by a single person. NOTE When transporting and storing the unit, it is important to ensure that the surface and front grill of the loudspeaker are not damaged. Moisture can penetrate through exposed wood surfaces and cause the wood to swell. A bent or broken front grill will no longer adequately protect the sensitive speaker membranes. In addition, appreciable dust deposits may prevent the loudspeaker membrane from working properly. For this reason, the loudspeakers should be transported and stored in a safe, careful, dry and largely dust-free manner. The following accessory parts for transport and storage are available from TW AUDiO: • CaseT24 (flightcase for two T24N) • CoverT24 (protective cover) • FDB30 (front dolly) The original packaging is not suited for permanent storing and transporting. 8 Operating Manual T24N 6.
