1. Introduction

Modeled on a classic British console EQ used in recordings by well-known artists like The Beatles and Led Zeppelin, the UK-69 adds astonishing detail to your audio. It allows Antelope Audio users to achieve depth and texture formerly the sole territory of standalone hardware.

The bass band is a stepped 50 Hz shelf filter or frequency selectable peak EQ, the treble band is a fixed 10 kHz shelf EQ, and the mid section sports a frequency-selectable peak or notch EQ with 8 frequencies available. The control panel is rounded out with a level knob and EQ bypass buttons.

This EQ is notable for its ability to preserve transparency while adding space and presence. Antelope Audio’s model of this highly coveted circuit delivers unprecedented authenticity!

1 EQ Cut Switch On/Off

Engages or disengages the equalizer. Doubles as the BP button in the AFX rack.

2 Bass Band Frequency Select Knob

Selects the bass band frequency. The following choices are available:

400Hz
240Hz
120Hz
60Hz
30Hz
0Hz
3kHz
6kHz
9kHz

3 Bass Band Gain Knob

Adjusts bass band gain.

4 Mid Band Frequency Select Knob

Chooses the target frequency for the mid-band. The following choices are available:

700Hz
1kHz
1.4kHz
2kHz
2.8kHz
3.5kHz
4.5kHz

5. Glossary

5.1 Shelving EQ
A shelf type EQ is the boost or cut of all frequencies above or below the cutoff frequency. It is most commonly found on the top and bottom bands of a parametric EQ.
5.2 Bell Curve
All equalizers with peaking filters use a bell curve which makes the EQ smoothly process a range of frequencies. With the bell curve, the center frequency occurs at the top of the bell curve and is the one most affected by equalization.
5.3 Low-cut Filter
Also known as high-pass filter. There are two types of pass filters in equalization. A high-pass filter (HPF) attenuates content below a cutoff frequency, allowing higher frequencies to pass through the filter. Thus, it is commonly used for cutting low frequencies. A low-pass filter (LPF) works the opposite – it attenuates content above a cutoff frequency, letting lower frequencies pass through the filter.
