Description: The Phono preamplifier adds a phono function to any amplifier or receiver with a backup AUX, CD/DVD audio line level input. With AUX input and volume control, AUX is without signal amplification. Can be used to directly input the turntable to a mixer or computer sound card. High quality phonograph preamplifier, for use with dynamic magnetic type jukebox. Gold-plated head input and output connection RCA port, reliable performance. The output level control allows the volume to be adjusted to provide signals from other sources. Specification: Distortion ratio: 0.06% (max). The frequency response is: + / -0.5dB, 20Hz -20kHz. Phonograph input impedance: Phono: 47K ohm- 200pFnominal. Line input impedance: AUXL: 10 K ohm. Output impedance: 200 ohms. Channel separation: 50 dB. Voice: 40dB (Phono) arbitrary signal source. Phono sensitivity: 3.3 MV. Output: 300 MV. SNR: 85 dB. Package Includes: 1 X PHONO Preamplifier Signal Amplifier 1 X stereo RCA to RCA line gold-plated interface (line length 150CM) 1 X 3.5mm stereo RCA line gold-plated interface (line length 20CM)
