A 1:1 CIRCUIT RECREATION OF THE ORIGINAL - NOW IN 1RU DUAL/STEREO FORMAT - utilizing the Louder than Liftoff HyperMatter™ PSU & CHASSIS!

AudioScape D3A DUAL LEVELING AMPLIFIER: A Compelling Compressor with A Dramatic Mid-Forward Color

Our newest addition to the AudioScape lineup, the D3A is an uncompromising, authentically Made-in-USA recreation of the timeless and enormously popular optical limiter from the 1970s known for its fierce midrange color & girth, characterful compression, and simplicity of operation.  And in true Audioscape fashion, an extraordinary amount of time, passion and obsessive attention to detail was spent refining and perfecting our take on this legendary circuit to ensure every unit behaves and performs just like the original - all at a peerless price point within reach of engineers working at ANY level.

**EXCLUSIVE PARTNERSHIP WITH LOUDER THAN LIFTOFF - Powered by HyperMatter™

This is our first product that features the brand new Hypermatter™ PSU & Chassis through an exclusive partnership with Louder than Liftoff.  We spent the last year developing a state-of-the-art power supply truly fit for the demands of high-resolution audio.  The goal was simple: to create a superior power delivery system whose noise, voltage regulation, and transient response performance is unparalleled.  It renders dynamic sound with revealing detail, dimension, and gut-punching authority.  The Hypermatter™ PSU architecture uses a 4-layer PCB, cutting edge LDO regulators, and nothing but the best components to bring the D3A DUAL to life in ways that must be heard.  Your music has never felt more alive.

MEGA-MONO CHANNEL (courtesy of Louder than Liftoff™)

In addition to offering both stereo (linked and unlinked) and dual-mono operation, the D3A DUAL is capable of becoming a ‘Mega Mono’ channel to facilitate more creative processing chains.  When the CH 1>2 switch is engaged, the output of channel 1 will feed into the input of channel 2 and put the magic of two D3A’s in series.  The channel 1 output will also still be available on its respective XLR connector.

Modifications, Handcrafted T4B Opto-Attenuator & Custom, Hand-Wound Transformers

Any GREAT piece of gear is truly the sum of its parts - not just a handful of “buzzword” capacitors, resistors, and transformers. The D3A features the “Clearmount Mod” fully integrated into its circuit - helping to lower the overall noise-floor and broaden the versatility of the “GAIN” control amongst other things, making the D3A an extraordinary, sonically multi-faceted compressor and tone box!

Handcrafted in the USA - Legendary Circuits deserve Legendary Craftsmanship

We build and assemble each of our products by hand here at our workshop in Florida, using NOS and USA-made components wherever possible, and never compromising or making concessions to any aspect of the build or more importantly, the SONICS for the sake of profit margins or simple convenience. We strongly believe this is the right way - if not the only way - to produce these units at the level of quality we strive for, while still making them available to as many of our customers as possible. Every product comes with a HASSLE-FREE TWO-YEAR WARRANTY, and we pride ourselves on providing the best customer service in the biz! If you have any questions, concerns, or just want to talk shop, please reach out to us!

WHY SHOULD YOU BUY A D3A?

- Proudly built in small-batches from end to end on site, in the USA by a small team of skilled assemblers. Each assembler is assigned 2 products, making them masters of their craft!
- Know where your hard-earned money is going and feel good about any purchase made from us! Every dollar spent helps feed a family, fund college tuition and supports new product development / R & D!
- Our margins are very tight. But this sacrifice allows us full control over every aspect of the manufacturing and assembly process.
- We are able to capitalize on the USA surplus market and use NOS parts where it matters and most importantly, we are able to offer a product that is (in our biased opinions), simply a step above the competition.

AUDIOSCAPE offers a HASSLE-FREE, 2-YEAR WARRANTY included with EVERY unit we sell!
**FREE PATCHRAT PRO SUBSCRIPTION INCLUDED WITH EVERY PURCHASE!**

D3A FAQ & CONTROLS (Switches - IN vs. OUT):

Is it in bypass when the button is pressed?
BUTTON IN = Unit Engaged
BYPASS BUTTON OUT = Bypass

Is it in comp or limit when the button is pressed?
BUTTON IN = COMP
BUTTON OUT = LIMIT

Is the HPF all the way off when turned clockwise or counterclockwise?
HF Control all the way COUNTER-CLOCKWISE means you're getting full-frequency compression (FLAT) as you turn the HF knob CLOCKWISE, more and more high-end gets COMPRESSED (this control works in an OPPOSITE manner to the HF EMPHASIS control on our OPTO COMP )

Metering button: +4dB and GR Button:
BUTTON IN = Output Level
BUTTON OUT = Gain Reduction

Is clockwise more compression or less?
GAIN and COMP work as you'd expect, as you turn them CLOCKWISE, you get MORE (be it GAIN or COMPRESSION)

How does the stereo linking work - mechanical telepathy or is there a physical connection somewhere?
Mwhahaha, love this one. Stereo Linking is achieved if your chassis allows it (usually there is a jumper inside (near the edge connectors) with a little jumper that will "link" Slots 1/2 or 3/4, etc...

What does the stereo adjust knob do?
THIS is a REALLY cool control - it will have an effect whether the STEREO LINK button is pressed in or not. It's "technical" purpose is to match the gain reduction between two units via the meter BUT it also has this BADASS, easter egg effect of allowing you EXTREME compression the more it's turned CLOCKWISE (and LESS when turned COUNTER-CLOCKWISE below the center detent). It's usually best left at 12 o'clock (center detented) but PLEASE experiment and let us know what you come up with!

A SWEET trick is to turn up the STEREO ADJUST knob as you turn up the COMP knob to get some INSANE compression happening - THEN simply turn the STEREO ADJUST KNOB counter-clockwise from where it's at to "ease off" of the amount of compression. It's easier to play with it than describe it but if you don't want to think about it just leave it at high-noon (again, center detent).

An easy way to remember what the buttons do is to press the METERING button and look at how it's labeled, with +4dB on top and GR below it.
Button IN = +4dB (output level)
Button OUT = Amount of Compression

To Surmise:
IN = Top Option (COMP or +4)
OUT = Bottom Option (LIMIT or GR)

When there is only ONE option labeled (in the case of BYPASS and STEREO LINK):
BYPASS:
IN =Engaged
OUT = Bypass

STEREO LINK:
IN = Stereo Link
OUT = Bypass Link (if two units are in use)
