Input Gain
The Red Eq equalizer provides three fixed bands at 80Hz, 1.8kHz and 8kHz, the upper and lower bands being shelving while the middle has a traditional bell response. There's an ample 16dB of cut and boost, and though the EQ may look limited compared to a parametric, it actually sounds nicely musical and the frequencies have been chosen with care. A five-section led level meter and an output gain knob allow you to control the overall output level from the unit up to a maximum of +6dB. A red warning lamp lights if the signal approaches clipping, due to excessive use of boost on already hot signals. It can be used to make adjustments in the most needed areas of the audio spectrum without the sound losing its focus.

Key Features


Logo Despite the digital revolution in the pro audio industry, many of today’s top albums are still mixed with analog outboard gear. Mixing with analog devices often still sounds better to many people. There is a very elusive and almost "magical" quality imparted from analog signal chains that is missing in the digital realm. There appears to be more weight to a mix, and the overall sound is more three dimensional. Analog devices produce electrical artifacts that affect frequency response, add harmonics, cause signal clipping and increase noise. These artifacts, which audio engineers often consider the character of a particular device, result from a combination of factors such as component grade, technology type (i.e. vacuum tubes, ICs, transistors), power supply specifications, equipment casing and other variables.
Depending on the circuit characteristics, input signal frequency response varies. Some circuits cut frequencies, others boost them. This behavior is part of the overall device character and should not be confused with user adjustable EQ.
Total harmonic distortion (THD) is based on the levels of the odd and even harmonics of an input signal, usually at a level much lower than the fundamental level. THD balance and decay are circuit dependent, and thus differ from device to device.
CrossTalk and Noise are two elements which every designer tends to avoid to not affect the audio quality. Since in the analog world they can't be avoided, fortunately in digital domain with Volterra Technology we have reduced the noise at less of -120dBfs and completely avoided CrossTalk during the sampling.
The result is an optimum full quality sound from a like-new working condition hardware.


Input Gain

Input Gain: sets the level at the input of the plugin. The range is from -∞ dB to +6 dB.

EQ in: This switch control sets the plugin operative or bypassed

Knobs 1

Low Shelf: The low band is controlled by knob, delivering smooth shelving equalization. The frequency is fixed to 80Hz and the available gain range is approximately ±16dB.

Mid Bell: The mid frequency band is controlled by knob, delivering smooth midrange equalization with a fixed bandwidth. The frequency is fixed to 1800Hz and the available gain which is approximately ±16dB.

High Shelf: The high frequency band is controlled by knob, delivering smooth semi-parametric high midrange equalization with a fixed bandwidth. The frequency is fixed to 8000Hz an the available gain is approximately ±16dB.

Meter: five-section led level meter.

Output Gain: sets the level at the output of the plugin. The range is from -∞ dB to +6 dB.
