Connect your turntable to line-level devices. The AT-PEQ3 is an RIAA turntable preamplifier that is designed to convert a turntable's phono-level output to an RIAA-equalized line-level signal for use with audio mixers, powered speakers, recording units, integrated amplifiers, computers, and other line-level devices. The RIAA preamp is a device that alters the signal from a turntable by applying an equalization curve and boosting the signal.
When a record is cut, the low frequencies are reduced and high frequencies are boosted; on playback the opposite occurs (low frequencies are boosted and high frequencies are reduced). The RIAA filter in the AT-PEQ3 provides both the playback equalization and the signal amplification needed for line-level devices.
