RDL TX-PA40D overview

  • 1Description

The TX-PA40D from RDL is a high-quality utility amplifier designed to drive a pair of 4 or 8 Ohm speakers. Ideal for fixed-gain applications, or where gain is controlled by other equipment, the amplifier has a compact, discreet design that allows it to be installed virtually anywhere.

The amplifier offers highly efficient Class-D operation, and has thermal and short circuit protection built in. Input is via a stereo RCA input, and output is via standard positive/negative wire connectors. An integrated compressor/limiter controls clipping, and an LED meter shows when the compression threshold is reached.

    RDL TX-PA40D reviews

    TX-PA40D 40W Stereo Power Amplifier with Power Supply is rated 4.0 out of 5 by 3.
    Rated 4 out of 5 by from nice sound, little package This amplifier has a nice sound and fits conveniently about a ceiling mounted projector. Its seems to run warm with little input gain, but it is not hot to the touch. I purchased 6 of these for a training room installation without a single problem. I recommend adding an EQ to the signal chain to prevent low end distortion (75Hz>). The manufacture should add a high pass/low cut switch.Good for prerecorded audio or speech reinforcement in medium sized rooms.

    Rated 3 out of 5 by from I wouldn't buy this product again. I purchased this product to amplify sound from my projectors output to a pair of JBL speakers in a conference room. Product is very easy to install and setup. In my install I get a lot of hiss from the unit through my speakers when feeding them and low sound output. The amplifier would be much better if it had tone control built in. Not a bad unit just doesn't work as well as I would like in my install.

    Rated 5 out of 5 by from Nice Little Amp Best solution for boardroom projectors. Nice and powerful given the footprint. Good full range sound. Has an imbedded condenser that causes a little hiss, back off the gains and increase volume with the source equipment.
