Featuring a custom Eclipse ET-DB2 transformer, it delivers warm, natural sound across the full audio spectrum while eliminating ground loop hum with BUZZ technology. Equipped with versatile Swiss military-grade inputs (1/4", RCA, 3.5mm), it supports a wide range of devices, making it an essential tool for technicians and audio professionals seeking reliable, distortion-free signal management. ## Description Radial proav1, proav2 is not an audio/video integrator specifically developed using passive direct box. The mono mixer has been developed to significantly simplify signal management through a variety of resistances of proav1 function stereo input. Proav2 features two channels that do not require full stereo functionality. For various adapters, both units are equipped with Swiss military array connection options, including 1/4" input, RCA and 3.5mm (1/8") connectors, CD players, iPods, videos, decks and computers. You can also choose proav1 function device communication + 4db Professional female XLR input signal level. Thu-putts can also be used as a front panel connector. Multiple patches are available. It is used at these points. Custom scratch Eclipse et-db2 transformer can withstand extremely hot while linear signal levels from 20 Hz to 20 kHz. The result is a smooth Vessel curve that is warm and natural and soundly in the processing of a fragile digital source. The isolation generated by the Transformer is more beneficial to eliminate ham noise and see BUZZ ground loop or DC offset issues. By combining these features, Proav1 and Proav2 are available in the 'Problem Solver' and the technician's toolkit. ## Features - Army Knife' Multimedia Direct Box - Easy to use, super passive design - BUZZ eliminates the ham noise caused by loops on the ground - Handle does not have loud sound distortion ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Radial | | Item model number | R800 1115 | | Product Dimensions | 7.62 x 16.26 x 10.67 cm; 650 g | | ASIN | B001ESK5NO | ## Images ![Radial Engineering ProAV2 Stereo Direct Box - Image 1](https://m.media-amazon.com/images/I/71kH4+5scFL.jpg) ## Questions & Answers **Q: It says "Input - Thru" on top, but where the thru signal come out?** A: All the inputs are connected in parallel, so you can access the thru signal from the RCA or 3.5mm jacks if you use the 1/4” inputs for example. If that works for what you need it’s great, but that’s one reason I don’t much care for the proAV2; you can’t just use it as a regular old passive instrument DI without specialty cables or adapters. I am an instrumentalist, DJ, and sound guy, and my advice for the ultimate in “oh sh#%” flexibility, is to get at least 1 proAV1 box. First off, they are excellent standard instrument DIs, so you can easily send signal to your amp and the board like you always have. Secondly, They have bailed me out of problems several times in my career when running sound, when pieces of gear have broken, or I’ve forgotten, or just don’t have, a particular cable. In those cases, it doesn’t matter if you preserve the stereo field; you just need to get a signal to any available input, and the proAV1 makes that easier. You can, for instance, sum a 3.5mm stereo signal from a computer or phone, into a single XLR or 1/4” output on the proAV1. With the PRoAV2, you better have 2 cables and 2 inputs on your mixer ready to go, or you won’t be hearing the left or right channel from your source, which could make for some really weird results. That said, For true stereo instruments, or preserving stereo signals from AV devices or computers, the proAV2 is the right tool for the job, but you must have 2 inputs available on your mixer. **Q: Could this Be used to Output main LR as a separate out into say a Video Camera/GoPro or Phone to get a MONO/Stereo Balanced Mixed?** A: Not sure what you are trying to accomplish. If your camera has a line out that you can connect a cable to, this will work, but not sure what you are trying to do. **Q: Can i use all 1/4 input and rca at the same time?(sending audio input from my keyboard(2 x 1/4) and audio input from my usb-dac(rca) ) thank you** A: I'm deferring all specific recommendations to the ProAV2 user guide, which can be found on the Radial web-page (http://www.radialeng.com/proav.php). My cursory view of the manual leads me to believe that all input connectors could be used because they are all summed by a resistor-mixer. Its multiple connector types are typically for convenience and can be used as "thru-puts", but summing various inputs does look possible. **Q: Is this the perfect gear if i use vst (pianoteq, kontakt) a lot? from the mac, it can convert to two xlr and for my 2 yamaha hs8 or hs5?** A: The proav2 is the swiss army knife and yes this is exactly the type of situation you would use this for.
