AD2077 Stereo Mastering Eq description:

The Avalon AD2077 Stereo Mastering Eq. Delivers great control in the bass, while keeping the midrange smooth and precise and everlasting high-end.

The Avalon AD2077 mastering equalizer is an ultraistic design optimizing absolute signal integrity. Design features include 100% discrete pure class A signal amplifiers, state- of-the-art passive and active filter topologies and a DC coupled minimalist signal path. These unique designs offer the professional mastering engineer alternate tone selections in both filter domains while delivering the highest resolution and wide dynamic range with very low noise. Custom gold rotary switches give accuracy in 0.5dB, 1dB and 2dB steps. 104 switched frequencies per channel with X I0 range selectors provide frequency selections from 12Hz to 25kHz at 1/4 octave intervals. The Avalon AD2077 mastering equalizer is one of the most musically transparent analog EQ available today.

The main features of the Avalon AD2077 include:

  • 100% discrete, pure class A mode
  • Wide bandwidth 1 Hz to 500kHz
  • High headroom +30dB
  • Passive and active filter design
  • Transparent minimal signal path
  • Very low noise -94dB
  • Balanced DC inputs and outputs
