A necessity for your audio toolkit
The ProAV1 provides you with the ability to connect almost any audio source to a PA system, while automatically summing stereo sources to mono to preserve channels and simplify the audio setup. Inputs are available via 1/4", RCA, 3.5mm stereo, and line-level XLR connections, giving you the ability to easily connect to smartphones, tablets, laptops, CD players, or even a +4dB line level output from a console or recording interface. Transformer isolation helps eliminate noise while maintaining a linear frequency response, and a mono balanced XLR output allows you to feed a recording interface or a PA system.

Consumer Audio to PA System
The ProAV1 is perfect for interfacing consumer audio electronics with pro PA and recording equipment. The dual phone, RCA and 3.5mm inputs on the ProAV1 sum the left and right stereo channels to a mono output.
Standard DI For Instruments
The ProAV1 works just like standard direct boxes for passive and active musical instruments like guitars, basses, and keyboards. You can thru-put the signal to an on-stage amp while transformer isolation keeps things quiet.

  • Versatile direct box for multimedia applications
  • Easy to use, ultra-quiet passive design
  • Transformer isolation eliminates hum and buzz
  • Handles huge transients without distortion

What is the difference between the ProAV1 and ProAV2?
Although both will accept stereo signals, the ProAV1’s output is mono (single channel) while the ProAV2 is stereo (two channel). The ProAV1 tends to be used in audio visual environments such as schools or hotels where stereo is not always available. The ProAV2 is usually selected for bigger events.

Do I need power to make them work?
No. Both the ProAV1 and ProAV2 are passive. In other words, internal transformers do the balancing and impedance matching. So no power is required.

Will phantom power hurt the ProAV1 or ProAV2?
No. Phantom power will simply be ignored.

How does the Radial ProAV2 compare to the Radial JPC?
The ProAV2 is passive while the JPC is active with transformer isolation. The ProAV2 can handle more signal without distortion while the JPC is optimized for pre-compressed program material such as that found on CDs. The buffers in the JPC can sometimes help quiet down computers while the same benefit can sometimes be had with the ProAV2 due to the 100% isolation. Both work very well.

Can I use the ProAV1 for bass guitar?
Yes. The ProAV1, which employs the same transformer as the Radial ProDI (our most popular direct box), allows you to connect instruments and thru-put the signal to an amplifier making it suitable for all types of instruments. Instruments can also connect to the ProAV2 but the thru output to an amp will have to be adapted from the RCA jack on the same channel.

What is the difference between the ProAV1 and the Radial JDI?
The ProAV1 is equipped with a wider array of connectors to suit the audio-visual market while the JDI is more focused at musical instruments. Also, the JDI uses a Jensen transformer while the ProAV1 uses a Eclipse transformer. The Jensen is flat from 10Hz to 40kHz while the Radial is flat from 20Hz to 20kHz.

Can I overload the ProAV2 using the output of a DJ mixer?
Yes. If the DJ mixer is running full volume it can certainly overload the ProAV2. Depress the -15dB pad to keep it from distorting. If the signal is still too hot, then reduce the output level coming from the DJ mixer.

Can I take the output from the ProAV1 and run it into a line level input?
No. The ProAV1 and ProAV2 have a mic level output. This needs to connect to a mic preamp input on the mic input on your mixing desk.

Why is the output of a direct box mic level?
DIs are always mic level. This enables the signal to be treated exactly the same way as a microphone. On busy stages, this makes managing signals much easier. It also reduces problems such as crosstalk that can occur if one signal is hotter than the other and they are being sent down the same path such as in a multicore snake.
