An All-in-one Centerpiece for Your Studio

If you rely on electronic instruments, such as synthesizers, electronic drums, and sequencers, the Phoenix Audio Theata is exactly what you need to level up the quality of your productions. All your sound sources will take on a larger-than-life quality, thanks to this unique unit's eight world-class high-impedance instrument preamps. You get 30dB of gain on each channel, along with per-channel highpass, polarity reverse, -15dB pad, and ground lift features. The Theata also includes a summing amplifier mixing suite with a flexible busing matrix that enables you to route any channel to an L/R bus. This amazing-sounding unit houses 10 '70s-flavored Phoenix Audio transformers to add weight to your tracks, along with all the I/O you could ask for. You also get a stereo width effect, a master insert send and return, plus bus linking for two units to build a 16-channel summing unit. Electronic musicians searching for an all-in-one centerpiece for their studio will be floored when they see what the Phoenix Audio Theata can do for their recordings.

Eight channels of instrument preamplification

If you want to produce top-shelf recordings, you need to treat DI-ed instruments with as much care as miked sources. That's where the Theata comes in. This outstanding rackmount unit houses eight world-class high-impedance instrument preamps, each with 30dB of gain for controlling, shaping, and coloring your tracks. Each channel also includes a variable 45Hz–250Hz highpass filter, along with polarity reverse, -15dB pad, and ground lift features. The engineers here at Sweetwater love how the Theata's '70s-style circuitry enhances the sound of our tracks. There's nothing like the sound of classic transformers, and the 10 custom-wound Phoenix Audio transformers in the Theata are among the most pleasantly colorful around.

Glorious analog summing

The Phoenix Audio Theata's Class A discrete summing amplifier mixing suite is just what you need to add character and dimension to your productions. You get an intuitive — and eminently flexible — busing matrix, which enables you to route any (or all) of your channels to an L/R bus. What's more, the Theata includes a master insert send and return, along with bus linking for two units, which allows you to create a top-quality, 16-channel analog summing solution.

Reviews

Delicious audio experience
A sweet analog Swiss army knife for a variety of situations- just as Phoenix Audio advertised. I love the sound of the transformers and I love the control you have over the inputs/outputs, routing and color. It's a mistake to only look at this unit as several preamps. You definitely have more tricks up your sleeve adding this to your setup (thru outs on the front panel are so slick). And TJ Deller here at Sweetwater always makes my purchases effortless.

Definitely snatch one.
