user manual QLight series 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

user manual QLight series Audio Input The signal input to the TQ-440SP is fully balanced, with an input impedance of 10kΩ . The input XLR connector is wired pin 2 hot (+ve), pin 3 cold (-ve), and pin 1 screen (shield). The link XLR connector is wired pin 2 hot (+ve), pin 3 cold (-ve), and pin 1 not connected. Multiple TQ-440SP enclosures may be driven from a single audio console, up to a practical limit of 16 units. Any more will cause unacceptable signal loss due to the loading of th

user manual QLight series Equalisation Because the TQ-440SP features a smooth and even frequency response, it does not need equalisation or correction to overcome the deficiencies often found in lesser designs. Should extended frequency response be required at more than medium sound pressure levels, the use of the complementary TQ-425SP self-powered subwoofer is strongly recommended In order to compensate for the room acoustics, the TQ-440SP requires only minimal equalisation. As in

user manual QLight series Arraying The TQ-440SP has a side-wall angle of 16º. Use this position for smooth horizontal dispersion that is ideal for many applications. With the high dynamic range capability and low power compression of the TQ-440SP you should find this wide angle arrangement adequate for all but the most demanding long throw requirements. It also has the advantage of needing fewer cabinets to cover the required area. When speakers are mounted together in close proximit

user manual QLight series Choosing the best location It was stated earlier that the TQ-440SP’s tightly controlled directivity gives it essentially point and shoot qualities. Every room has its own unique set of characteristics that affect any sound introduced into the room. These include reverberation reflections and decay time, sound absorption of materials used, temperature and humidity, etc. A degree of experimentation with different locations (if possible) is best, especially if y
