Gyratec G14: Stereo Parallel-passive Equalizer

Gyratec G14: Stereo Parallel-passive Equalizer

The G14 is a true tube, all passive, stereo equalizer. It consist of five bands – each with 11 switchable frequencies, variable “Q”, and boost/cut selection. It also has an output level trim, and a “hard” relay bypass control.

G14 is as standard available as a 230V mains unit – other mains voltages will be made on request (at no extra cost)

  • Warranty
  • All units are sold prepaid – If you wish, we can negotiate a two-week return/money-back option for customers that have no other way of trying out the units, like in countries that don’t have distributors yet. This would allow you to return the unit, all you need to pay is the shipping expenses both ways.According to the danish consumer rights you have two years of warranty. You can only complain about errors which were there when you recieved the product, or where the cause of the error was there at the delievery.

Description

Design

With a classic design the G14 will fit into every studio. The two handles make it easy to transport or move the product, and the material of the switches is a must feel experience.

Tech

The two channels are linked – controlled with one set of knobs. The “Q”s (filter sharpnes’es) are rather low when boosting, but higher at cut – approaching a notch on extreme cut settings.

Specifications

Input impedance – Around 5K Ohms, transformer balanced. Output impedance – ~1K Ohms, transformer balanced. Max boost/cut – ~10-12dB, depending on “Q” setting. Gain trim ~+3 – -5dB. Each band individually hard-bypassable. Channel tracking within ~1dB.

Reviews

There has never been a bigger selection of valve-based EQ available to us.. You have never used an EQ as smooth, silky and satisfying as this one” George Shilling, Resolution Magazine

SKU: g14 Category: Use carefully - this is in no way a fire-and-forget gadget: Multiple types of interacting nonlinearities are at large, even a few in macroscopic time-domain because of components heating and temperature coefficients. Changing something in one band will sure as hell result in something else showing up somewhere else. Feels organic in that. Classic problem is that multi-banding gives inadequate results because of filter phase shift messing up recombining. We deal with this by NOT band-splitting, but in stead dealing with all frequencies in parallel fashion, only opening frequency-selective channels into the clipping circuitry. Byproduct of this is that spike/peak phase is altered first, only to be real-clipped if pushing the phase won't get the total signal below threshold. Kinda like an audio file hair-remover (work title of the G21 was "The AudioShaver") As we all know, clipping generates harmonics - there's simply no way around that. But what you do with those harmonics will make a lot of difference. The beauty is here, that as the clipping is done at the remote end of a frequency selective channel, the clipping byproducts (harmonics, at frequencies multiple times the clipped) have a hard time getting back out and into the audio, because they are now no more in the right frequency range.. And other than the three bands of clipping, we have an overall clipper that can be set for linear (white), pink -3dB/oct or red -5dB/oct emphasis - enabling gradually lower "threshold" at higher frequencies. Then there's a fine-trim for output level and a 18dB/oct lowcut at the input - mainly because most of our test pilots were mastering engineers Input impedance - around 5K Ohms, transformer balanced Output impedance - ~1K Ohms, transformer balanced Max boost/cut - ~10-12dB, depending on "Q" setting Gain trim ~+3 - -5dB Each band individually hard-bypassable Channel tracking within ~1dB Frequency markings are: Low: 35-48-60-70-80-100-120-160-190-220-270Hz Low mid: 180-230-280-330-400-430-490-550-590-650-750Hz Mid: 500-570-700-800-900-1K-1K1-1K3-1K5-1K8-2K1 Hz High mid: 950-1K2-1K4-1K7-2K-2K5-3K-3K5-4K2-5K-6K3 Hz High: 4K5-5K6-6K5-7K8-9K1-12K-14K-16K-18K-20K-22KHz
