Product description

SQM Multimedia Support presents the WorkPro compact PA 40/2 USB mixing amplifier, which is equipped with an integrated MP3/WMA audio player. The files can be opened via USB-A connector and SD/MMC card slot. Both devices cannot exceed 32GB of storage. The played content is controlled from the position of the LED display and eight buttons on the front panel.

The front interface also offers two 6.3mm microphone inputs with the ability to prioritize the first channel (MIC 1). There are also 4 knobs available to the user - two that corrects gain for each channel, a tone control knob, and AUX control knob.

The rear panel shows Pre Out/Amp In (RCA) socket and two RCA connectors for the AUX input. The continuous output power of the amplifier is 15 watts, and the peak value reaches 30W.

A big feature of the amplifier is the possibility of connecting a 12-volt power supply, low impedance speaker (4-8-16Ω) and cooperation with 100-volt lines. The equipment maximally consumes 36 watts of power.
