2.1. DOWNLOAD AND AUTHORIZATION

Indigo, and all Acustica Audio products, can be downloaded, installed, and authorized using the

Aquarius desktop application, our dedicated free app for macOS and Windows. When you purchase

a product on the Acustica store, the registration is automatic. For more information, please visit our

website.

Please note: make sure Aquarius is constantly updated to the latest version. If you experience any

issues during the authorization of your products, uninstall the plugin(s) and then re-install them us-

ing the latest version of Aquarius.

2.2. SYSTEM REQUIREMENTS

Modern computers are powerful enough to run many plugins at once. However, our technology re-

quires more resources than algorithm-based software. Please, consider optimizing your system to

work with high CPU loads and low audio latency.

2.3. WHAT IS A “ZL” PLUG-IN

Acustica plugins come in two versions: ZL (zero latency) and a regular version. While the ZL version

does not introduce any latency to your system, the standard version does. This buffer varies in size

for each plugin and helps reduce the CPU and system load of your computer signicantly.

We recommend that you use a ZL instance when tracking. Basically, both plugin instances are iden-

tical, but the current Acqua engine can work either with or without an audio buffer. The idea behind

a ZL instance is to give you the option to run an Acqua Effect with minimal latency, which is helpful

for tracking or direct monitoring.

NOTE: Please keep in mind that for each plug-in in the Indigo suite we recommend that you cali-

brate your input levels to: -18dBFS = 0dBu.We suggest that you do not overload the input.This

way you will avoid any unwanted distortion or unpredictable behavior due to exces sive input levels.

3. OPERATION

Indigo is packed with an authentic collection of esoteric mastering unit emulations, highly sought-af-

ter by collectors from all over the world. It includes two Stereo Equalizers, a dual-mono Compres-

sor, a Stereo Compressor-Limiter, and a Stereo image processing tool.

3.1. INDIGO STEREO TUBE MASTERING EQUALIZER ( EQ1)

The Indigo EQ features a 6-band Stereo Parametric EQ derived from a rare, all-tube Stereo Master-

ing Equalizer, hand build in Denmark. Probably the most sought-after unit included in this collection.

It is based on a tube circuit designed in the 1960s.

The operating principle is that of frequency-controlled ampliers, a topology that allows a better

global phase linearity. It is a state-of-the-art equalizer built using only the highest quality compo-

nents. Equipped with 22 valves, this equalizer shines on any instrument, but mastering is its spe-

cialty.

the ‘Input Trim’ mode has no effect. It is possible to increase the harmonic saturation with this Input

trim knob.

9-11-15 Low/Mid/High Frequency: The Low, Mid, and High controls manipulate the three EQ

bands, but in a way that adds more dynamic, harmonic content the higher the EQ is set. NOTE: the

Mid control covers a massive amount of territory while the Low and High controls are much narrow-

er in comparison.

10-Mid Shift: alters the response of the Low and Mid controls, essentially assigning the low mids

to either control.

NOTE: M and S buttons are mutually exclusive, this doesn’t allow you to make changes to both the

Mid and Side channels at the same time.

12- M button: when the MID button is selected, EQ processing is applied to the center of your soundstage.

13- Stereo button: When this button is enabled, the input signal to the plugin is split into two pro-

cessing channels, Left & Right. The signal is ‘summed’ back to Stereo at the plugin’s output.

14-S button: when the SIDE button is selected, processing is applied to the edges of your sound-

stage.

3.2. INDIGO STEREO TUBE EQUALIZER (EQ2)

Indigo Stereo Tube EQ 2 is a 3-band Stereo EQ derived from a modern, discrete, class-A tube ste-

reo EQ, with input and output Jensen transformers.

This is a one-of-a-kind, wide-range EQ, so to speak, that focuses on broad-frequency brush strokes

rather than honing in on specic frequencies. Thanks to its ‘Aggression’ control, it can heat up your

sound considerably by generating very musical harmonics.

Indigo Stereo Tube EQ2 is geared more towards mastering, but its versatility and sonic ‘beauty’

make it an ideal tone-shaping machine during the production phase.

3.2.1. STEREO TUBE EQUALIZER - Controls

NOTE: M and S buttons are mutually exclusive, this doesn’t allow you to make changes to both the

Mid and Side channels at the same time.

16- Vintage switch: toggles between a “modern” mode (more hi sound), and a “vintage” mode (an

old school sound, more darker)

17- Air: boosts the ‘ultra’ high frequencies

3.3. INDIGO STEREO SHUFFLING PROCESSOR

Indigo Stereo Shufing Processor is a Stereo image processing tool characterized by switchable

High-Pass and Low-pass lters with a 3 or 12 dB/oct slope and a Tube Preamp section equipped

with two different emulations.

This is an ambitious and unusual plugin that pays homage to two different units, dusting off some

concepts and techniques that are perhaps a bit outdated today but are part of the history and evo-

lution of the recording world.

1) The rst unit we sampled for this plugin is made entirely in Italy, designed and built by Marco

Bosisio for Tesla Audio Laboratories (http://www.teslaeng.it). It is a high-pass and low-pass tube LC

lter (inductor-capacitor) with buffered output.

Both HP and LP lters normally affect the stereo program, but they can also be routed on the Mid

or Side components of the signal. In particular, used in this mode the HP lters operates as a very

effective passive elliptical LC lter that comes in handy in both its 3 and 12dB/oct slopes. In order

to provide maximum versatility to the user, we added a low-pass version of the same lter as well.

TIP: if you’re mastering for vinyl, these types of lters denitely come in useful.

2) The second unit is our take on a transformer-based, valve-buffered stereo processor designed to

correct the typical issues of certain stereo mic techniques. Usually, this concept is often associated

with the term ‘shufing’ invented by Alan Blumlein in the early 1930s; hence the name Stereo ‘Shuf-

ing’ Processor.

Its 10-step Stereo Field Manipulator allows you to exploit an emulation of the original Blumlein’s

shufer processor, the notable ‘Spreader’ circuit developed for popular ‘60s British tube consoles,

plus the emulation of an entirely new stereo correction technique for crossed cardioids, ORTF, and

NOS arrays.

NOTE: The technique of spreading low frequencies across the stereo eld is completely at odds

with the way mastering for vinyl generally works: use with care!

Moreover, we have complemented the original four modes with six intermediate ones (1,2,4,6,7,9)

to allow a smooth transition from one to the other.
