Watching the studio-gear paradigm progress has been interesting. Years ago, of course, everything was analog. Then the digital era hit, and many of us switched to completely in-the-box systems for the advantages they provided. But these days, many studios (including mine) are switching to a hybrid approach - using the best of both digital and analog. A big part of the growing popularity of the hybrid approach has been the rise of the API 500 Series format, which condenses pro studio gear into compact modules that can be loaded into a rackmount or portable chassis.

recently released a family of modules, including two brand-new pieces that were first shown at the 2013 Winter NAMM show. I was able to load up all four into a chassis and take them for a spin. There are two preamps: the , which combines an RND preamp with an opto compressor and RND's signature Silk control, and the brand-new , which is a preamp with Silk and a variable highpass filter. The 517 actually has two paths, mic and DI, which can be blended. Both modules sound phenomenal, with a full but open tone. The Silk control allows you to shape the tone, adding a subtly smooth texture.

The is RND's mono VCA compressor. It offers full control over all parameters, plus a choice of RMS or peak detection, feed-forward or feedback operation, and the ability to sidechain with or without a highpass filter in the path. I found it to be transparent, with just a touch of added "polish" - the tracks I ran through it sounded subtly enhanced in that beautiful Neve fashion.

Also brand-new is the . This tape emulator module can do great things to your audio, adding beef and rounding out harshness while adding desirable harmonic content. You get a saturation control, a blend control for mixing in the effect, and the choice of 15ips or 30ips tape-speed simulation - as well as the ability to add Silk to the signal. Here's my favorite setting: 30ips, fairly heavy saturation, the blend set to around 50%, and a good amount of the "blue" texture setting. It's analog heaven!

Rupert Neve has really hit the mark with these modules. All the Portico sound is there, with plenty of control and powerful sound-shaping options, but in the compact, affordable 500 Series format. Outstanding!
