Unison™ Technology for Stunning Mic and Guitar Preamp Emulations

Apollo Solo USB's Unison technology gives you the tone, touch, and “feel” of the world's most sought‑after preamps. These include the bundled UA 610‑B Tube Preamp, plus authentic mic preamp emulations from Neve® and API,® plus guitar amp emulations from Fender® and Marshall® — complete with their signature impedance, gain stage “sweet spots,” and component‑level circuit behaviors.*

The secret to Unison is its hardware‑software integration between Apollo Solo USB's mic preamps and its onboard UAD-2 processing. Simply place a Unison preamp plug-in on your mic input in Apollo's Console software, and it physically reconfigures Apollo’s impedance and gain staging — giving you the classic tube and transformer sounds of the world’s most recorded mic preamps and guitar amps.

A Full Suite of Classic Studio Processing Onboard

Right out of the box, Apollo Solo USB provides a suite of incredible analog emulation plug‑ins including the world’s only authentic Teletronix LA‑2A and 1176LN compressors, Pultec EQs, and much more. From the tube warmth of the Pultec EQ on guitars, to the gentle limiting of the LA‑2A on vocals, your recordings will take a giant leap forward in rich, sonically complex analog sound.

Vintage Guitar and Bass Amps

For guitarists and bassists, Apollo Solo USB includes Unison technology on its front panel instrument input — giving you access to dead-on emulations of amps like the Fender® '55 Tweed Deluxe, Ampeg® B‑15N Bass Amplifier, and the included Marshall® Plexi Classic — all available at near-zero latency for songwriting and recording.

Best-in-Class Headphone Amplifier

Apollo Solo USB's onboard headphone output is louder and punchier, with lower noise and flatter frequency response versus any interface in its class. This means you can confidently track and mix using headphones, knowing you're hearing every sonic detail.

Ready to Go

With its robust all-metal construction and exceptional sound quality, Apollo Solo USB is the only desktop audio interface for Windows users that truly delivers professional results. It’s like having a virtual analog studio that fits onto any desktop, and easily travels in your laptop bag.

Included Plug-Ins

Realtime Analog Classics Bundle

With the Realtime Analog Classics plug-in bundle, you get legendary compressors like the Teletronix® LA-2A and EQs like the Pultec® EQP-1A, stunning guitar and bass amp emulations from Softube, as well as UA’s landmark 610-B Tube Preamp and EQ plug-in.

UA 610-B Tube Preamp and EQ

Impart your tracks with the iconic warmth and character of the classic hardware used to track everyone from Duke Ellington to Coldplay. By emulating the entire signal path, including tube amplifiers, transformers, and circuit nonlinearities, the 610-B Tube Preamp and EQ plug-in injects organic detail and saturation to any signal — whether you’re re-amping or tracking through the 610-B via Universal Audio’s Unison™ technology.

Marshall® Plexi Classic Amplifier

The undisputed alpha dog of rock and roll guitar amps, the Marshall “plexi” amplifier is as legendary as the music it helped create. From Jimi Hendrix to Jimmy Page, Duane Allman to Eric Clapton, the Plexi’s punishing melange of snarl, sustain, smoothness, and raunch defined the sound of rock. Developed by Softube, the Marshall Plexi Classic Amp plug-in gives you the sound of this iconic amp with a perfectly placed microphone from engineer Tony Platt who recorded AC/DC’s Back in Black and Highway to Hell.

Teletronix® LA-2A Classic Leveling Amplifier (Legacy)

With its gentle, program dependent optical compression and meticulously designed tube amplifier, the LA-2A is the go-to compressor for professional mixers around the world — especially for vocals. Incredibly easy-to-use Peak Reduction and Gain controls gives you the ideal optical compression sound for guitar, bass, drums, and more.

1176SE/LN® Classic Limiting Amplifiers (Legacy)

Get classic, ultra-fast FET compression from the world’s most recognized compressor. The 1176 will impart punch, presence, and character as well as its signature distortion overtones on drums, vocals, guitars, and bass. The 1176LN has graced countless recordings, from Led Zeppelin, to the White Stripes and Michael Jackson.

Pultec® Pro Equalizers (Legacy)

Mix with two of the most sought-after hardware EQs ever made — the MEQ-5 Midrange Equalizer and the EQP-1A Program Equalizer. Both of these tube-based icons deliver smooth and silky EQ curves with an abundance of warm analog character.

Ampeg® SVT-VR Classic Bass Amp

Introduced in 1969, the Ampeg SVT bass amp is still the reigning king of high-powered tube bass tone. Developed by Brainworx, the Ampeg SVT-VR Classic Bass Amp plug-in perfectly captures the raw power and punch that has made this the go-to amp for rock, funk, and soul players. Track in real time using Unison™ preamp technology for the tone, touch, and feel of a real SVT bass amp, or transform bland DI tracks with the thunderous roar of a stone cold classic.

Precision Mix Rack Collection

Featuring the Precision Channel Strip, Precision Reflection Engine, and Precision Delay Modulation plug-ins, the Precision Mix Rack Collection offers four modern, high-fidelity plug-ins for recording and mixing. Powerful and intuitive, Precision Mix Rack Collection gives you an impressive tool set — perfect for beginners and seasoned professionals alike.

Raw Distortion

Modeled from a vintage early-’80s Pro Co Rat, Raw Distortion delivers all the gritty dynamic raunch of the legendary stompbox. And with Unison™ technology, you can plug in to Apollo Twin, 8, or 8p’s front-panel Hi-Z instrument jack and experience the same circuit interaction, gain range, and clip points for the true tone, feel, and response of the original hardware.

RealVerb Pro

RealVerb Pro is a flexible, natural sounding reverb based on UA’s own unique set of algorithms. Allowing you to design the room just as you hear it, the RealVerb Pro goes beyond simply big/small or dark/bright, giving your sources distortion-free, smoothing diffusion control and ultra-long reverb tail.
