Audio-Technica AT-PEQ30 Phono Equalizer

Phono Equalizer for MM and MC Cartridges

The AT-PEQ30 adds a dedicated phono stage to a turntable system or upgrades an integrated preamplifier. It accepts both moving magnet and moving coil cartridges through a selectable input with fixed gain and impedance settings. High-quality FET inputs and a negative feedback equalizer circuit keep the signal path quiet. The all-metal enclosure shields the circuitry from radio and electronic interference.

Fixed Gain Settings for Cartridge Matching

The MM input presents 47 kiloohms impedance and 4.5 mV sensitivity, while the MC input offers 120 ohms and 0.28 mV sensitivity. These fixed values suit a broad range of cartridges without adjustment. Builders needing variable loading or adjustable gain for low-output MC designs will find the controls absent. Precision components deliver an accurate RIAA response within the defined input parameters.

Passive Thermal Design and External Power

The unit runs without a fan, relying on its metal chassis to dissipate the low heat produced by the analog circuitry. An included AC adapter supplies power, keeping the mains transformer outside the signal enclosure. Gold-plated RCA connectors maintain clean contact for the stereo input and output. No power consumption or noise floor figures are provided by the manufacturer.
