What it does

Filtek MK3 models a 1970s German three-band EQ built for broadcast studios to the strict standards of the IRT (Institut für Rundfunktechnik). Antelope chose the three-band version with high- and low-pass filters, which it calls the most recognisable and flexible form, and describes it as "clean and transparent" with punch when pushed.

Three bands: each with 12 selectable frequencies and ±16 dB of stepped gain, so settings are easy to repeat and recall.
Q switch: a three-way switch per band; the middle position bypasses that band.
Filters: wide-ranging high- and low-pass filters for cleaning up lows and taming the top.
Parallel EQ: blend the dry signal with the EQ'd one for gentler or more unusual tonal shaping.
Transformer I/O: modeled input and output transformer sections add the hardware's color.
Metering and bypass: an output peak meter and a bypass switch for the whole module.

Version 1.0.1 needs no Antelope hardware; a Synergy Core real-time version also runs on compatible Antelope interfaces. It is also part of the Antelope Cosmos subscription (75+ plugins), which has a free trial.

When to use it

Filtek MK3 is a stepped vintage parametric with a parallel mix, good for repeatable, colored moves on tracks and buses. Compared with Pro-Q 4 and TDR Nova it has fixed frequency steps, only three bands and no dynamic EQ, but it adds transformer color and is quick to set by ear. It is more precise than the Pultec Passive EQ Collection or the Mäag Audio EQ4, with selectable mids and Q, though it lacks the Mäag's Air band. Its parallel mix makes heavy, colored settings easier to blend in without losing the original sound.

Best for: tone shaping on vocals, drums and buses, cleanup with the filters, and parallel EQ.
Genres: any; it is a general mixing EQ with a vintage broadcast flavor.
Look elsewhere if: you want continuous controls, many bands or dynamic EQ (Pro-Q 4 or TDR Nova), or a big airy top end (Mäag Audio EQ4).
