Grace Design m102 Single-channel Opto Compressor at a Glance:
  • Extreme tonal purity
  • Straightforward operation
  • Seamless integration
Extreme tonal purity

We could go on all day about the technical differences between the current-feedback-based transimpedance amplifiers Grace Design uses and typical voltage-feedback op amps, but it's the kind of clarity you simply have to hear. The best part about the m102's extremely clear optical compression is that you can couple it with any other gear and get amazing results. Paired with a transparent preamp (such as the m101) and you get the compression you need, without coloration. Paired with a highly colorful preamp, you get sonic warmth without adding too much character to your sound. That makes the m102 a perfect addition to any rig!

Straightforward operation

These days, it seems like gear manufacturers are downright obsessed with adding every extraneous bell and whistle to their gear that they can get their hands on. What's nice about the Grace Design m102 is that it gives you exactly the controls you need (threshold, attack, release, ratio, as well as both input and output gain), so you can simply dial in specific level of compression you need. That kind of control is extremely rare for a genuine optical attenuator-based compressor!

Seamless integration

How will your Grace Design m102 fit into your studio? One of the nice things about the m102 is that it's ready to drop into any system. Its handy 1/2U format lets it butt up nicely next to your Grace m101 preamplifier, or you can link it with another m102 in stereo mode. A pair of parallel balanced inputs and outputs also let you choose from XLR or TRS connections. You also get a sidechain input for extra versatility, and a bypass switch lets you easily A/B your dynamics.

  • Elegantly simple, ultra-clean optical compressor that lets you level signal without distorting your sound

Exactly What I Was Looking For

I've been really thrilled with my Grace m101 pre, and wanted to complement the rich, clean gain with some smooth, transparent compression. I've had good experiences with the FMR Audio RNC, but have been frustrated by its unbalanced connectors, and also find that it can sometimes rob my recordings of some richness and detail. I record storytelling/narration pieces, and it's imperative that they feel intimate and present, so I decided to see how the m102 fared. I'm here to report I couldn't be happier. As others have said elsewhere, you really don't know it's there until you really drive it hard, and even then it's still fairly subtle compared to other compressors I've used. It doesn't seem to color the sound at all on more gentle settings, and while I can't comment on how well it would be suited for recording music, it's pretty much perfect for the spoken-word work I'm using it for. Naturally, it pairs beautifully with the m101--but I can't imagine you'd have bad results with any pre's input. For my budget, it's a lot to spend for compression on a single channel, but it's also delivered exactly the sound I was hoping for, and that's worth a lot! I was really happy to see that Sweetwater's carrying them--they're hard to find. You should buy one so that they continue to stock them!

A perfect Match

I have been looking at the Sweetwater catalogue for a long time now in search of a match for my Grace m101 pre-amp. So when they came out with the m102 it was a no brainer. I have a nice input chain for my DAW that consists of a Robbie pre-amp by Blue and a Summit Audio TLA-50 and love the warm sound that the tubes bring. But when i do background vocals with the same input chain the tube character makes it difficult to place the background vocals in the mix. No problem now though, with the ultra clean Grace pre and compressor combo placing background vocals is a snap. Also great on percussion because of the ultra fast attack and clean compression. I love both of my Grace products and dollar for dollar the just can't be beat.
