The QTA-D range of digital power amplifiers have been designed with practicality and versatility in mind.

Four models are available in the range, a single channel240W (QTA1240D), a single channel 500W (QTA1500D), a two channel 240W (QTA2240D) and a 4 channel 240W (QTA4240D).

The entire QTA-D range has been developed with green power saving technology whilst delivering long life and lowcost operation.

The APFC (Active power factor correction) switch-mode power technology means that the QTA-D series operates at 85% efficiency compared to standard commercial amplifiers.

This is achieved while maintaining relatively low heat generation, even under severe working conditions.

The QTA-D series all feature phoenix connector line inputs as well as an RJ45 port for remote power, volume and status monitoring control.

Remote power on/off can also be activated via the RJ45 port.

The QTA-D series also features 100v transformerless line speaker outputs.

Volume control for each channel can be accessed directlyfrom the front panel.

Status indicators include signal, peak and protection as well as an automatic mains power supporting AC 190V to 240V.
