Frequencies aren’t fixed at the default values, and you can proportionally scale all bands to
provide more focus on a portion of the overall frequency spectrum. This flexibility makes
it great for precise signal shaping and also a useful tool for tasks such as tuning difficult
rooms.
Vintage Graphic EQ parameters
You can change the standard frequency by dragging the Tune field.
• In/Out switch: Turn the EQ circuit on or off.
• Tune field: Drag to set the frequency of all band sliders. Scaling of frequencies is
proportional. This can be used to tune the bands to your project key.
Tip: When set to +12 you can boost 32 kHz which results in a very smooth high-end
boost.
• EQ band sliders: Drag to cut or boost the selected frequency of the incoming signal by
± 12dB.
MainStage Vintage Tube EQ
Vintage Tube EQ emulates two retro EQ units that were often paired as they complemented
each other. These units are still in use today, despite being out of production for decades.
The main original unit (upper) that Vintage Tube EQ is based on is a valve-equipped analog
design. It is a lossless passive equalizer. This means that the signal level remains constant
even if the EQ is switched out. The original unit is noted for the “musical” quality of its
filters, making it a versatile tool for mixing and mastering.
The low-frequency section of Vintage Tube EQ is a shelving EQ with sweepable frequency
bands between 20 and 100 Hz. These frequencies can be boosted by 13.5 dB or cut by 17.5
dB. You can create unusual EQ curves by simultaneously boosting and cutting overlapping
frequencies.
The Vintage Tube EQ high-frequency section provides up to 18 dB of boost at frequencies
sweepable from 3 to 16 kHz. A Bandwidth control changes the Q value. A shelf-cut EQ
provides up to 16 dB of attenuation between 5 and 20 kHz.
