## What is RRS EQ3?

EQ3 AUv3 plug-in — comes as time-limited Demo-version for you to try. It gives you 5 minutes of Free play time. (You can reload the EQ3 AUv3 plug-in as many times as you want, thereby you get the Demo period again and again.) Unlimited version of EQ3 AUv3 plug-in comes as In-App Purchase.

In the '80s it was the first to use a different approach to tonal adjustments. In conventional analog equalizers, whether they are shelving, sweepable, graphic or parametric types, various sections of the audio spectra are boosted or attenuated by adding or subtracting bandpasses. In this case, frequency shaping is achieved by summing bandpasses. Our emulation of this method is quite similar to the original and improved with additional possibilities of digital technology. Now you can hear it for yourself.

There are five broad, overlapping, interacting bands: 10 (Sub), 40, 160, 650 and 2.5 кHz, along with the «rock (airy) band» control, which is an HF boost-only control.

Features:

• Standalone and AUv3 plug-in;
• Precise port of Rack Extensions plug-in;
• Modeled vintage EQ;
• Boost only shelf at 2.5 kHz, 5 kHz, 10 kHz, 20 kHz and 40 kHz;
• 2.5 kHz fixed boost and cut shelf;
• 650 Hz fixed boost and cut bell;
• 160 Hz fixed boost and cut bell;
• 40 Hz fixed boost and cut bell;
• SUB (10 Hz) fixed boost and cut bell;
• Stereo (Mono), Mid or Side EQ modes;
• Undo/Redo;
• A/B comparison;
• 2x/4x/8x Upsampling;
• Macro controllers;
• Built-in Gain Match;
• Scalable GUI.

When using the EQ3, remember that the bands are broad, approximately 2 octaves. They overlap one another. For example: when boosting the 10 kHz «rock band» to a +6 position on the knob, to keep the response flat through in 2.5 kHz region you should rotate the 2.5 kHz coarse knob to about a -1 position. The amount you back off the 2.5 kHz control should, of course, be set by ear. Following this kind of procedure will accomplish a more airy sound, with much more clarity.

You can accomplish the same thing for the low frequency response by applying the same principles. The EQ3 will reach further into your mix than you've ever heard before with minimal phase distortion.

As a result, you may need to take a little time and «play around» with the controls on the EQ3 before you can make intuitive adjustments.

To use EQ3 as a plug-in, you need an AUv3-compatible host app like GarageBand, Auria, AUM, Cubasis and more — EQ3 will appear in the list of Audio Unit extensions for effect plug-ins in the host app.

### 5/5 — FABULOUS

*2024-09-14*

The short review: BUY THESE PLUGINS! They’re useful, effective and seamless . They use minimal cpu and are affordable!

The review :I have the EQ3 and the CL1. They are easy to use and a match made in heaven in Auria . These plugins are game changers for me!
Making records with a ONE mic drum approach and the EQ3 “808” setting (and my taste on the eq) gives a nice SHEEN along with balance and fullness. I use compression sparingly and the CL1 works perfectly. Again, using my ears to finely shape tracks to create space for instruments. Acoustic drums/guitars/amps/bass/keys and vocals are the usual suspects into Apogee Jam (1st gen)-duet iOS-iPad 9th gen- Auria Pro. The EQ173 is next in line.

Thank you RED ROCK SOUND 🔥🔥🔥🔥🔥
