Audio-Technica Introduces AT-PEQ30 Phono Equalizer

Although called a phono equalizer in reference to the RIAA curve, this $229 phono preamp is designed to improve the sound quality of most turntables.

High-Performance Phono Stage

Audio-Technica today introduced the AT-PEQ30 phono equalizer for $229. The compact hi-fi component is a phono stage designed specifically to add a phono stage to a turntable setup or to upgrade a turntable’s built-in phono preamplifier. The AT-PEQ30 accommodates MM (moving magnet) and MC (moving coil) phono cartridges and delivers what the company emphasizes as “superlative sound quality.”

The Audio-Technica AT-PEQ30 offers a selectable MM and MC input with a fixed gain of 35 dB (MM) or 59 dB (MC). Its input impedance is 47 kiloohms for MM and 120 ohms for MC, for compatibility with a wide range of phono cartridges. The AT-PEQ30 delivers a 250 mV line-level output for both MM and MC cartridges.

The AT-PEQ30 is built from premium-quality precision components, with a machined aluminum front panel, gold-plated input and output connectors and other refinements. Its FET inputs ensure low noise and precise RIAA equalization with a smooth, accurate tonal balance from 20 to 20,000 Hz. Measuring just 1.9 inches high by 7.8 inches wide by 4.9 inches deep for easy installation in any system, the AT-PEQ30’s all-metal construction provides superior isolation from outside electronic and radio frequency interference (EMI and RFI).

“Our new AT-PEQ30 is ideal for users who need a great-sounding phono stage for use with a turntable that doesn’t have a built-in phono preamp. It’s also a high-value solution for listeners who want to upgrade from their turntable’s built-in phono preamp and enjoy improved sound quality from their record collections.”

Bob Peet, Audio-Technica US Marketing Manager
