System Requirements

The TQ-440SP is a self-powered loudspeaker system. It comprises two independent amplifier channels: one channel to power the low frequency driver (LF) plus another channel to power the midrange (MF) and high frequency (HF) together; and a frequency dividing network to split the signal and feed it to the appropriate driver section. Additional features such as accurate and optimised peak limiters for both high and low frequency sections are incorporated into the control electronics. The TQ-440SP does not require the use of external amplifiers or crossover/limiters.

Additional TQ-440SP units may be daisy-chained together simply by linking the signal connections throught the input / link XLR connectors. In this way exact coverage of an event or permanent installation may be achieved using a number of self-powered loudspeakers. It is however necessary to route individual power cords to each enclosure as it is not possible to daisy chain through the power connectors.

AC power requirements

The TQ-440SP is equipped with a Neutrik Powercon AC mains connector, which mates with the power cord supplied with your unit. The TQ-440SP operates with mains voltages either in the range from 100 to 120 volts a.c. or from 220 to 240 volts a.c. The mains voltage on your unit will have been preset at the factory prior to shipment. However for clarification please check that both the product and the power cord match the mains supply available in your area before use.

Should it be necessary to alter the mains voltage setting, for example when touring a country with mains voltage supply differing from that of the country of original shipment, the mains voltage switch is located on the inside of the amplifier module adjacent to the mains transformer. Follow the instructions given in the Maintenance section of this manual for removal of the amplifier module, and change the voltage setting to match the available supply.

The mains fuse is a 3.15A 20mm anti-surge type for 230v mains supplies, and 6.3A 20mm anti- surge type for 115v mains supplies. Should it ever be necessary, always replace the fuse with the identical size and type.

Power Amplifiers

The TQ-440SP is equipped with two high power amplifiers designed with sufficient headroom to handle large signal transients without break up or distortion, in contrast to other self-powered designs which attempt to compromise using inadequately powered amplifiers. The LF amplifier delivers 250 watts r.m.s., while the MF/HF amplifier delivers 150 watts r.m.s.

TQ-440SP specifications

The Turbosound TQ-440SP is a powerful and versatile subwoofer that has made a significant impact in the world of professional audio. Designed with precision and performance in mind, the TQ-440SP stands out for its ability to deliver deep, impactful bass while maintaining clarity and balance across various applications.

One of the main features of the TQ-440SP is its robust construction. Built with a durable wooden enclosure, it provides both strength and resonance control, ensuring that the sound produced is not only loud but also clean and distortion-free. This is essential for live sound reinforcement, as well as installed applications in venues such as clubs, theaters, and concert halls.

The TQ-440SP is equipped with a high-performance 18-inch driver that is engineered to handle high power levels and produce exceptional low frequency output. This driver technology allows for an impressive frequency response, reaching down to 30Hz, which is crucial for genres that rely heavily on bass, including electronic, hip-hop, and orchestral music.

Another noteworthy technology in the TQ-440SP is its advanced system processing. The integrated digital signal processor (DSP) features advanced algorithms for crossover, limiting, and equalization, allowing users to tailor the subwoofer's performance to match specific room acoustics or system configurations. This capability enhances overall sound quality and ensures optimal performance, regardless of the setting.

Moreover, the TQ-440SP is designed for easy integration with other audio components. Its dual-input connectors accommodate a variety of input options, making it versatile enough to work with different mixing consoles and amplification setups. Additionally, it can be combined with Turbosound's other loudspeakers to create a cohesive sound system that delivers full-range audio experiences.

Portability is another consideration in the design of the TQ-440SP. Weighing in at a manageable level, it can be transported and set up with relative ease, making it an excellent choice for mobile applications such as touring and events.

Overall, the Turbosound TQ-440SP is more than just a subwoofer; it is a comprehensive solution for sound professionals seeking high-quality, reliable low frequency performance. Its combination of powerful drivers, advanced processing, and practical design features make it a go-to choice for demanding sound applications, setting a standard in the realm of professional audio equipment.
