The Phoenix Audio DRS1R/500 is a mono pre amp and DI for the API 500 series, it was designed to be identical in terms of features and sonics as the ever popular DRS1 but in a new format. The unit runs at 24v thanks due to the special power supply built into the unit so it offers no sonic sacrifices whilst still maintaining a very low current use needed for the API format and is well within its API VPR limits.
Test i Sound on Sound, UK:
"I also tried the preamp on both male and female vocalists in an indie/rock band, as well a male rap vocal, pairing it with some of my usual vocal mics — and this was where this preamp really shined. That Neve-ishness helped give all of the vocals a slightly enhanced texture, the result being that they just seemed to ‘sit’ slightly better, in a way that’s really difficult to define in words. Again, I could push the level harder into the output stage to coax more character out of the transformer. You have to be confident to work in this way, but I actually found it quite difficult to overdo this effect on vocals. The preamp coped comfortably with my gain-hungry Shure SM7B dynamic, and I’d expect it to have more than enough for most ribbon mics too.
Although they don’t sound quite the same, in general I found myself liking the DRS-1R on the same sources on which I’d typically choose a Neve 1073: vocals, bass guitar, kick drum and electric guitar. I’d highly recommend trying it out if you’re on the lookout for a high-quality vocal preamp that adds a touch of ‘colour’."
