Category information

If you dream of running a range of analogue audio gear but can't afford or accommodate a 19-inch rack set-up, then take a look at our catalogue of 500 Series modules and racks. It's the same thing, just a lot easier on the wallet.

500 Series Rack Modules

While the 500 Series system was originally developed by API, these days there are dozens of brands that serve up modules and racks. 500 Series modules are both cheaper and more compact than their 19-inch counterparts because the power supply comes built into the rack instead of the modules.

The Best Way to Amass Analogue Gear

Unlike 19-inch gear like preamp units, 500 Series modules give you the freedom to create completely custom set-ups, allowing you to build your own recording channel strips or your own array of preamps from brands like API, Solid State Logic and Neve.

Upgrade Your Audio Interface With a Custom Channel Strip

While most modern audio interfaces come equipped with pretty good preamps, some studio techs and recording artists want something that doesn't sound as 'clean'. By building channel strips out of 500 Series modules, you can easily make your recording set-up sound any way you want.

Stereo or Mono

Stereo compressors and equalisers can be set up by simply pairing two modules. As a matter of fact, some 500 Series racks even feature a stereo switch per two units, which is particularly useful if you want the option to unleash stereo compression on your mixes. It's worth mentioning that you can also get stereo 500 Series modules.

Radial EXTC 500 Series Guitar Effects Interface

Neatly packed in a 500-Series module, the Radial EXTC-500 Guitar converts the line level signal of guitar effects to hi-Z and back again so they can be seamlessly applied to audio.
