823Q - Pultec-type passive mono equaliser

The 823Q is like the 822Q but has different (more closely spaced) centre frequencies for its controls but follows similar principles.

The 822Q is a Pultec-type passive mono equaliser (with valve electronics providing unity-gain buffering) for general-purpose studio EQ duty.


  • Low boost & cut frequencies - 20, 30, 60, 100Hz; 0, +14, - 18dB variable
  • High boost frequencies - 3k, 5k, 7k, 10k, 12kHz; 0, +18dB variable
  • Maximum output level (1% distortion) - +25dBm
  • Input and output impedance - 600 ohm nominal, balanced and floating
  • High cut frequencies - 6k, 10k, 20kHz; shelf 0, - 18dB variable
  • Bypass switch - no level change, clickless
  • Operation - Passive equaliser with balanced valve output

Tim De Paravicini has been making these classic valve Eqs, Compressors and Mic pres for many years.
