TUBE TECH - EQ1A

The TUBE-TECH EQ 1A is a full range one channel unit, featuring low and high cut, low and high shelving and three overlapping bands.

The cut filters are designed around unity gain amplifiers and the shelving and bell filters are designed around two tube operational amplifiers.

All the gain controls are fitted with a boost/cut switch to widen the gain range.

As an option the TUBE-TECH EQ 1A can be fitted with rotary switches instead of pots (EQ 1AM), to give more precise settings.

The unit is all tube based except for the power supply. Input and output have fully floating transformers. All DC voltages are stabilized, except the anode voltage for the output stage.

Features:

  • Low cut at 6 frequencies (Slope 6dB or 12dB/oct.)
  • Low shelving at 6 frequencies (+/- 15dB)
  • High cut at 6 frequencies (Slope 6dB or 12dB/oct.)
  • High shelving at 6 frequencies (+/-15dB)
  • Band 1-3, bell type (36 overlapping frequencies 12 per band). (+/- 20dB with variable bandwidth).
  • All switches gold plated
  • Master bypass with clickless relay.
  • Conductive plastic pots.
  • All 7 sections fitted with separate in/out switch.
  • Freq. resp.: 5Hz to 60kHz
  • Very low noise: <-85 dBU
