Model: PP999 Output level: 2V Reference voltage: 1V Load impedance: 10K ohm S/N ratio (with A-WTD): 70dB THD: 0.08% for 1 kHz, 3 mV input Frequency response: 20 Hz ~ 20 kHz 2 dB Input sensitivity / impedance / phono: 3 mV / 50K ohms Dimensions (W x H x D): 9 x 5.5 x 2.6 cm Package List: 1 x Phono Preamp - CONVERTS PHONO SIGNALS: This phono preamplifier converts phono signals to line-level signals. Designed to support magnetic pickups with an input sensitivity of 3 mV at 50 k ohms. - LOW-NOISE OPERATION: Features low-noise audio op amps for clear sound performance. Maximum output is 2 V (PP) into a 10 kOhm load. For best results, place the preamp close to the audio source to minimize interference. - CONNECTS TO TURNTABLE: Enables connection of any turntable to modern audio devices lacking a dedicated phono input. Compatible with receivers, speakers, computers, and laptops for amplified sound. - PLUG AND PLAY: Compact design with stereo RCA inputs and outputs. Connect turntable to RCA inputs and ground wire, then connect output to amplifier or receiver via RCA cables.
