RDL RU-AFC2 overview

  • 1Description

The RU-AFC2 by RDL is a stereo bi-directional audio format converter. The bi-directional format allows the RU-AFC2 to fully convert the stereo input and stereo output of a consumer audio product to professional balanced standards. It can equally convert the stereo input and stereo output of a professional audio product to consumer unbalanced standards. The audio fidelity, low noise, low distortion and excellent crosstalk performance of the RU-AFC2 are suited to critical applications.

Unbalanced audio connections are available on front-panel RCA jacks. Balanced audio connections are available on front-panel XLR jacks and on rear-panel detachable terminal blocks. The shield connections of the XLR output jacks are connected to the case through a rear-panel ground-lift switch. The unbalanced to balanced section includes an additional MONO summed output on a rear-panel detachable terminal block which may be wired balanced or unbalanced. The mono output may be used to drive patch-bay jacks, powered monitors or subwoofer amplifiers.

Each of the left and right outputs is equipped with a dual-LED VU-meter. The intensity of the green LED is proportional to the audio level. The red LED flashes at the calibrated output level, -10 dBV unbalanced or +4 dBu balanced. An individual multi-turn level trim control is provided on the front panel for each output channel.

    RDL RU-AFC2 reviews

    RU-AFC2 - Stereo Audio Format Converter is rated 3.0 out of 5 by 2.
    Rated 2 out of 5 by from Nice piece of hardware if it worked? Maybe it is just me but I was not able to get this device to work. Maybe the power supply is bad. Maybe my brain is just bad? The unit seems well built and has incredible specs. During a live show I was attempting to record a live board feed to my Marantz 671. I could get nothing in the unit; no signal LED or output. Power supply seemed properly attached and I was able to confirm signal using a different setup. I attempted to adjust the level screws but nothing seemed to work. I would like to give this unit a better rating and maybe after some more testing I can give a better update.

    Rated 4 out of 5 by from Best of what's available I had to buy the power supply. Running from tube line preamp out a duel mono balanced analog XRL into this. Then It's pushing this signal out duel unbalanced RCA into a cassette recorder. Has green signal indicator for signal and red for high. It also does the reverse at the same time. I'll be getting another as I want to run 2. This gear is well made.
