The Retro Channels. Take Control of your audio.

Audient is known for super clean mic read more pres but that doesn't mean they don't understand the importance of adding color. Whether you need to add growl to a bass guitar or make those vocals sparkle, ASP800's revolutionary harmonic generation circuitry has got you covered.

Color Your Sound with HMX and Iron Controls

Retro Channels 1 & 2 feature two unique variable harmonic COLOR controls per channel - HMX & IRON. Designed to emulate tones often associated with 1960s tube designs and the coveted transformer zing of British audio in the 1970s, HMX & Iron will add a dimension to your audio by providing warm, sparkly tones. Better still, you can combine them to get anywhere in between!

HMX: Tube-Style Harmonic Distortion When You Want It

Plenty of engineers love the sound of tubes/valves and if you're one of them, then you're going to love HMX. Travel back in time with ASP800's very own custom harmonic distortion control. Similar to vintage valve preamplifier designs of the 1960s, HMX provides a sweet, thick tone that will sound incredible on anything from drums to electric guitars. By using discrete MOSFET technology, HMX produces asymmetrical harmonic distortion giving you the option to add richness and body to the pristine tone of the Audient mic preamp, DI or line input. Take control of your sound and bring your audio to life, 1960s style.

IRON: Audient's British transformer saturator

A testament to innovation, IRON uses a custom British transformer with a high voltage MOSFET drive network designed to recreate that sparkly, "sounds like a record" signature of 1970s recording. With one control that simultaneously alters drive impedance, bass response, high frequency damping, phase shift, magnetic saturation and transient shaping -- IRON can instantly add sparkle, growl and so much more with one twist of a knob! It sounds killer on snare, bass, acoustic guitar and anything that needs some extra bite.

Pristine Converter Technology. Brilliance on the inside enables brilliance on the outside.

ASP800 provides you with high performance 118-dB AD converters from Burr Brown, the leaders in converter technology. Quality in the analog stages of design comes from years of experience as analog console designers, and when coupled with outstanding converter technology it enables you to hear audio as it's supposed to sound. The importance of converters should never be underestimated.

Experience audio the Audient way. Plug and Play. Plug in and be inspired.

As well as offering you 8 channels of mic pre, ASP800 has two harmonically rich JFET D.I inputs. Designed to replicate the input stage of a classic valve amplifier, you can plug your guitar, bass, keyboard or drum machine and start recording instantly.

Built to Last. Quality deserves protection.

The result of years of experience in analogue design combined with a focus on precision and detail, ASP800 packs a powerful feature set in an ergonomic 1RU rack mount. From its beautifully crafted hand milled aluminum knobs to its all-metal construction, ASP800 will stand up to countless late nights in the studio and days on the road.

Perfect addition to to any adat input. I have a UAD Duo and I could not ask for a better setup.
The clarity that it offers is a revelation. It puts you in the game for creating really great recordings.
HMX and IRON are so good that they offer a different option if you need different preamp flavors on top of the ones you have. If you've invested in different pres for your studio this may be an unexpected treat.
Ease of Use
It's as easy as can be. I use Studio One DAW and Control Two in UAD and it recognized it immediately. Audient has a great but underated reputation. It's a major win for all enthusiasts.
This thing is a tank. It may last longer than me lol. Really thought it is one of the best built pieces of rack gear I've seen in a while.
In it's catagory it's a little more expensive but you end up with an extension that is worth far more.
Manufacturer Support
With their reputation I don't suspect that I would need it but I've heard nothing but good things in that department.
The Wow Factor
The sound is the wow.
