Today, many amplifiers do not have a specific phono cartridge input. Phono Box E is an ideal phono preamplifier for these hifi systems. Phono Box E accepts MM cartridges and offers an audiophile music experience at an entry-level price. Advanced circuitry and SMD construction keep noise and distortion at a surprisingly low level. A built-in internal shielding and an outboard DC power supply leave no risk for external interference. Because of its small casing, Phono Box E can be placed near the turntable. Input and output sockets are gold-plated for preservation of quality. Phono Box E can be connected easily to a line-input (AUX etc) of your amplifier. Features Amplification and RIAA equalisation for MM cartridges Design principle inspired by Dr. Sykora SMD circuitry Special low-noise components Internal metal shielding Small size allows installation close to record player Gold-plated RCA connection sockets Outboard power supply included Black or White casing Technical Specifications Input impedance: 47 kohms Input capacitance: 120 pF Gain: 40 dB Output voltage(typically): 500mV/ 1kHz at 5mV/1kHz Noise floor: 88 dB (A weighted) THD:
