Unpacking the TXD series loudspeaker

After unpacking the unit please check carefully for damage. If damage is found, please notify your supplier at once. You, the consignee, must instigate any claim. Please retain all packaging in case of future re-shipment.

System Requirements – Passive Models

TXD series loudspeakers, with the exception of the TXD-252 and TXD- 15M, are passive systems, and require only one amplifier channel for correct operation, the frequency splitting between the LF driver and the HF driver being accomplished by the internal passive crossover network built into each enclosure. These models are equipped with Neutrik Speakon NL4MP connectors for both input and parallel connections. Pins 2+ and 2- are not used for passive connections. Always observe the correct polarity as shown.

System Requirements – Bi-amped Models

The TXD-252 and TXD-15M are switchable passive/bi-amp systems, and when used in bi-amp mode require two amplifier channels and an external electronic crossover for correct operation. These models are equipped with a single switchable Neutrik Speakon NL4MD-V-S connector (in addition to two regular NL4MP connectors for passive mode), with pins 1+ and 1- being used for the low frequency amplifier and pins 2+ and 2- for the high frequency amplifier. Always observe the correct polarity as shown.

Using Passive Loudspeakers with Subwoofers

TXD series subwoofers are equipped with internal passive crossover networks which enable a system of, for example, TXD-121 and TXD-115 units to be configured together as a full-range system without the need for external electronic crossovers or additional power amplifiers. The subwoofer’s internal crossover filters high frequency signals out of the subwoofer cabinet to ensure a clean transition.

Amplifier considerations

TXD speaker enclosures should be driven by high quality power amplifiers designed for true professional use. Amplifiers should be capable of delivering long term broadband power equal to the loudspeaker’s program power rating at the stated nominal impedance. Always operate your power amplifiers at maximum gain for the best headroom and signal/noise ratio, controlling the overall system volume from the mixing console. The use of under-powered amplifiers must be avoided as heavily clipped signals can cause permanent loudspeaker damage.

RECOMMENDED AMPLIFIER POWER RATING

The amplifier’s rated r.m.s. continuous power output (20Hz – 20kHz, each channel)

should be equal to the loudspeaker’s program power handling at its nominal impedance.
