A designs audio 500 hr

Perhaps the best known way to rack mount a couple of individual 500 series modules in a single rack space is the A-Designs 500HR - a dual slot 500-series power supply and frame.

It has balanced XLR input and output for 2 mono channels, and can supply +48V phantom power. In addition to being the perfect companion for A Designs Audio 500 series modules, the 500HR is compatible with most VPR Alliance modules, and is the most affordable solution for any pair of 500 series processors. The 500HR can be used with all sorts of different modules to give you all sorts of customizable functionality. Loaded with two preamps it becomes a dual-channel mic pre; with two A-Designs EM-PEQs, it's a dual-channel, Pultec-style equalizer; and with one preamp and one EQ it is a complete pre/post EQ recording channel. Plus, using the preamp and EM-PEQ configuration, you can bypass the preamp on your guitar/bass/keyboard amplifier to give you a totally different amp for live performance. Preamp and compressor, compressor and delay and EQ, two different kinds of EQ, one tube and one solid- state compressor - the possibilities are literally endless.

Great if you just have 2 modules

This is a great way to turn two 500 modules into a one rack space piece, and unit worked well when I tried it out.
I did have trouble fitting 500 modules into this box. I had to remove the metal covers on the units so they would fit into the A 500 HR Rack. So there is some lacking in compatibility between manufacturers which needs to be addressed, if its not too late, with so many 500 units out there.

Like it....

This rack keeps the look of the studio very uniform, unlike half-filled lunch boxes. Very easy to install components. Cool piece of gear.

World class construction, but no gold on XLR's

Good but

I have to say that you have to be careful whith this unit with preamps because of the internal power supply. I used a Chandler 500 series preamp and it made a buzz/humm. It works fine with eqs and compressor but be careful using preamps.

Not all 500 Series units will work with this unit...........please contact 3rd party manufacturers of the unit you have questions about for that information.

We have found that some units will draw more mAs than what is advised by The VPR Alliance (visit the API site for that information) and some are double wide and will not fit in the open slots of the face plate.
