462 - 10 Band EQ

The 462 10-Band Equalizer is a graphic, fixed band, proportional Q design.  This means that as you increase the boost or cut of a particular frequency the Q adjusts from a broad to narrow.  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:

  • Polypropolene/Polystrene film capacitors
  • Audio-grade Electrolytic capacitors in the signal path and Low ESR for power rails
  • 1% metal film resistors (hand matched where needed)
  • THAT 1200-series input reciever with 90dB CMRR at 60Hz
  • Burr-Brown Op-amp in the gyrator circuit
  • 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.  This means that as you increase the boost or cut of a particular frequency the Q adjusts from a broad to narrow.  It gives you alternate fixed EQ points of 40/60/80/200/400/600/1.5K/3K/5K/10K.  The frequency spread was established with EQing Kick drums in mind.  You can add boom, thump, dig out mud, and add punch and clarity with this EQ.  It's also great on bass, electric guitars and keyboards. 

It features:

  • Polypropolene/Polystrene film capacitors
  • Audio-grade Electrolytic capacitors in the signal path and Low ESR for power
  • 1% metal film resistors (hand matched where required)
  • THAT 1200-series input reciever with 90dB CMRR at 60Hz
  • Burr-Brown Op-amp in the gyrator circuit
  • Custom USA made Nickel/Steel OutputTransformer
  • Custom centre-detent slide-potentiometers (Centre LED lights to indicate 'engaged')
  • Relay True-Bypass 
  • nine.18 op-amp
