The ASR Mini Basis is a phono preamplifier for Moving Magnet (MM) and Moving Coil (MC) pickup systems. Like all ASR amplifiers, the technology of the “small” ASR phono preamplifier Mini Basis is built into a housing made of high-quality, slightly transparent acrylic glass. A variety of adjustment options through input resistance and amplification allow each pickup to fully exploit its inherent sound qualities.Not least thanks to the sophisticated power supply, the ASR Mini Basis sounds very dynamic, with a very powerful and controlled bass. The sound has a precise spatiality and is combined with a very good resolution of details. The sound is typical of ASR products, very relaxed and unobtrusive.As with the emitter, many additional customer requests in the area of equipment can be realized. Features Housing made of low-resonance, slightly transparent acrylic glass Highly efficient, shielded 72 VA PM (Philbert jacket cut) transformer Particularly high-quality core sheet with a low stray field for high dynamics Ultra-fast and low-loss Schottky diodes, 200,000 uF screening Extremely fast and low-noise measuring amplifier ICs Adaptable to MM and MC pickups using two DIP switches Input resistance can be switched with a 10-fold DIP switch between 12 and 47,000 ohms (47KOhm) Gain adjustable with 6-way DIP switch from +30 dB to +70 dB Specifications Mini Basis Signal-to-noise ratio > 60dB (depending on the settings) RIAA equalization < 1dB deviation from 20Hz to 20kHz Distortion < 0.01% THD Transformer 72 VA Total sieve capacity 200,000uF Fuse 500 mA slow Dimensions and weight W x D x H 268 mm x 350 mm x 110 (HV130) mm - approx. 5 kg
