Red Rock Sound HLF-3C completes the Passive EQ Collection. This plug-in has 12 dB per octave low and high cut filters, providing broad retro-tonal sculpting or bygone-era special effects, without the inconvenience of insertion loss found with the unamplified passive hardware.

You can easily subtract the unnecessary frequencies in any instrument and sub-group so they stay wonderfully musical in the mix.

The original HLF-3C hardware unit is a true passive design; there are no input/output amplifiers and it does not require any external power. As a result, there is an inherent loss of signal level when using the HLF-3C hardware. The RRS HLF-3C plug-in compensates for this inherent signal loss for simplified use in the modern era; it has unity gain upon insertion (there is no insertion loss until one or both of the cut filters is engaged).

BasiQ2 is an update of our Baxandall Simple Equalizer, a free 3-band equalizer plugin. This simple and straightforward tone shaping tool is modeled after the style of a classic shelving Baxandall Equalizer, renowned for its slick slope and natural-sounding filter. We overhauled the whole engine, interface, and also added new features for this multi-purpose tone adjustment device.

BasiQ2’s straightforward controls allow you to add presence, clear the mids, or boost the bass as necessary. It is suitable for mixing and mastering purposes with its neutral and wide bandwidth where it’s more beneficial as a sweetening tool than as a surgical or corrective EQ.

Key Features:
NEW! Updated interface with resizable window.
NEW! Dark and light mode
NEW! Portrait or landscape orientation
NEW! Low pass and high pass filters
NEW! Preset management and A > B compare.

The EQ560 Free based on Classic American EQ from the late ’60s, the 10-Band graphic
equalizer features precision filtering and high headroom, ideal for signal enhancement.

The curve shaping potential is unmatched, while unique Proportional Q design intuitively
widens the filter bandwidth at lower boost/cut levels and narrows it at higher settings.

The EQ560 Free is handy when you need to make EQ adjustments on larger parts of the
spectrum instead of a restricted area. Boosting or cutting several bands at once will radically
alter the sound of a track, be it a thin, weak snare that needs low end or a dull vocal that
needs to be opened up.

Gain Sliders
Each of the 10 sliders controls the gain for one frequency band. Each band can be adjusted
to boost or cut the frequency by up to ±12 dB. The available band frequencies are listed
below.

EQ560 Frequencies
31Hz, 63Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz, 16kHz
Tip: To return a slider to the 0 dB position, double click on the gain fader.

EQ IN
The EQ is active when the EQ IN button is engaged and its associated LED is illuminated. When this button is off, selected EQ is disabled.

Mixbus Tone Control – closest to analog

FlavourMTC follows classic “passive” equalizer designs where the EQ circuits itself are not able to amplify signals but a dedicated amplifier stage takes care of it. Those EQ designs are well known for allowing very transparent frequency changes while their amplifier designs do add some icing on the cake quite often.

FlavourMTC implements this by utilizing 1st order shelving filter designs avoiding unwanted resonances and takes advantage of “zero delay” implementations for most accurate higher order filtering and w/o introducing curve warping near Nyquist frequency.

The output amplifier stage of the plugin can be calibrated according specific mixing levels, provides a distinct “box tone” and glues everything together. Parts of the plugin are oversampled internally for maximum transparency and sound quality.

Classic Baxandall EQ for Gentle Tone Shaping

TL BaxEQ is based on the simple yet elegant scheme of Baxandall’s original analog device, and has the high level of transparency and flexibility that only digital implementation can offer.

Flexible visual interface with multiple display modes allows you to fully monitor audio signal dynamics, while straightforward, realistic controls enable you to get started without any confusion or hassle.

Baxandall EQ is a special type of shelving equalizer developed by English audio engineer Peter J. Baxandall back in 1950. Its shelves have a wide and gentle Q-factor with a greatly minimized phase shift spread over a wide area, which gives them a very transparent and musical sound. This special trait has kept the Baxandall EQ extremely useful in mixing and mastering for well over half a century.

Whether you want to add presence, sparkle, brightness or air to your highs without making them too harsh, or you want to add thickness and weight to your lows but keep them from getting boomy or muddy, Baxandall EQ is the answer.

TL BaxEQ rack consists of two separate sections for high and low frequency control. The analog-style interface lets you easily adjust the shape of the Bax shelves, set the gain level for each, and cut any unwanted edge frequencies for the best hit in your mix. For best results, you can always monitor the input/output signal and the shape of the EQ curve on the visual display.

Animated EQ Curve

Animated EQ Curve lets you follow exactly how BaxEQ affects certain frequencies in real time. Changes to any parameter are immediately shown on the graph, giving you a better understanding of the Bax shelves shape and allowing you to achieve the desired results in a quicker way.

Accessibility Features

With a fully scalable interface and the option to customize the info shown on the display, you can arrange your TL BaxEQ workspace in the most convenient way possible.

The lightest DSP ensures minimal CPU usage: you can handle multiple plug-in instances without any visible load on your device.

No DAW? No Problem! TL BaxEQ comes in both VST and Standalone formats, so you don’t necessarily need a DAW to utilize all its features.

System Requirements:
TL BaxEQ comes in 64-bit VST / VST3 / AU / Standalone.
Windows 11, 10, 8, 7 or Vista (64-bit only);
macOS 10.13 or higher (64-bit only);
Ubuntu 18 or higher (64-bit only);
