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: 3 mV / 50K ohms Dimensions (W x H x D): 9 x 5.5 x 2.6 cm Package List: 1 x Phono Preamp 1. CONVERTS PHONO SIGNALS: A turntable preamp that converts phono signals into line-level signals. This state-of-the-art phono preamplifier can accommodate magnetic pickups with an input sensitivity of 3mV at 50k ohms. 2. Low-Noise Operation: Offers excellent performance with low-noise audio op amps. The output is a maximum of 2 V (PP) at 10 kOhm. It is recommended to position the preamp close to the source to reduce unwanted noise and interference. 3. CONNECTIONS TO TURNTABLE: Connect any turntable to any modern sound device without a dedicated phono input for music amplification. This can be connected to receivers, speakers, computers, laptops, and more. 4. Plug and Play: This mini preamp has stereo RCA inputs and stereo RCA outputs. Connect the turntable to the RCA inputs and ground wire. Then connect the amplifier or receiver to the RCA outputs.
