Behringer PP400 Microphono Ultra-Compact Phono Preamp

Behringer PP400 Microphono Ultra-Compact Phono Preamp

The Behringer PP400 Microphono phono preamp converts the low-level signal from a turntable's magnetic cartridge into a line-level signal for mixers, amplifiers, recording equipment, and stereo systems without dedicated phono inputs. It also applies the RIAA equalization required for proper playback of vinyl records.

Designed as a compact problem solver for vinyl playback systems, the PP400 accepts stereo RCA input from a turntable and provides both stereo RCA and 1/4-inch TRS output options. Its approximately 47 kOhm input impedance accommodates magnetic phono cartridges, while 35 dB of gain raises the cartridge signal to a usable line level. A grounding terminal provides a connection point for a turntable ground lead to help establish the intended phono setup.

The PP400 uses an external 12 VDC power supply and consumes approximately 1.5 watts, making it easy to integrate into home audio, DJ, and recording configurations. The compact metal-format unit weighs only 0.4 lb and measures approximately 4.1 x 2.5 x 1.3 inches. Its straightforward fixed-gain design requires no complex setup: connect the turntable, select either output format, and route the resulting line-level signal to the receiving audio equipment.
