462 - 10 Band EQ
The 462 10-Band Equalizer is a graphic, fixed band, proportional Q design. Increasing the boost or cut of a particular frequency narrows the Q. It gives you the classic fixed EQ points of 31/63/125/250/500/1K/2K/4K/8K/16K. The 462 is a general workhorse that will provide musical and defined EQ on any source material, but shines particularly on guitars, drums and vocals. The circuit is based around a very low distortion line reciever, that feeds high-precision op-amps to drive the EQ circuit, then through a socketed op-amp (2520 format) into a custom wound Nickel/Steel output transformer for the ultimate sonic enhancement.
Key Features:
- Polypropylene & Polystyrene film capacitors
- Audio-grade Electrolytic capacitors in the signal path and Low ESR for power rails
- 1% metal film resistors, 0.1% in critical locations
- Burr-Brown gyrator Op-amp
- Custom USA made Nickel/Steel OutputTransformer
- Custom centre-detent slide-potentiometers with the centre LED to indicate operation
- Relay True-Bypass
- nine.18 op-amp
462K - 10 Band EQ
The 462K 10-Band Equalizer is a graphic, fixed band, proportional Q design. Increasing the boost or cut of a particular frequency narrows the Q. The 462K was designed to live on a kick drum insert with EQ points of 40/60/80/200/400/600/1.5K/3K/5K/10K. You can add boom, thump, dig out mud, and add punch and clarity with this EQ. It's also great on bass, electric guitars, keyboards and vocals.
It features:
- Polypropylene film capacitors
- Audio-grade Electrolytic capacitors in the signal path and Low ESR for power
- 1% metal film resistors (hand matched where required)
- Burr-Brown gyrator Op-amp
- Custom USA made Nickel/Steel OutputTransformer
- Custom centre-detent slide-potentiometers (Centre LED lights to indicate 'engaged')
- Relay True-Bypass
- nine.18 op-amp
