Περιγραφή
Phono preamplifier for Moving Magnet (MM) and Moving Coil (MC) pickup systems. The technology of the “small” ASR phono preamplifier Mini Basis is installed like all ASR amplifiers in a housing made of high-quality, slightly transparent acrylic glass.
A variety of adjustment options through input resistance and amplification allow any pickup to fully play the inherent sound qualities.
Not least due to the elaborate power supply, the ASR Mini Basis sounds very dynamic, with a very powerful and controlled bass. The sound image is of precise spatiality and associated with a very good detail resolution.
The sound is typical as for ASR products, very relaxed and unobtrusive.
As with the emitter, many additional customer requests can be realized in the area of equipment.
- Noise voltage ratio: > 60dB (depending on the settings).
- RIAA equalization: < 1dB deviation from 20Hz to 20kHz
- Distortions: < 0.01% distortion factor.
- Transformer: 72 VA.
- Total screen capacity: 200,000 uF.
- Fuse 500 mA inert.
- Housing made of low resonance, slightly transparent acrylic glass.
- Highly efficient, shielded 72 VA PM (Philbert jacket cut) transformer.
- Particularly high-quality core sheet metal with low scattering field for high dynamics.
- Ultra-fast and low-loss Schottky diodes, 200,000 uF screening.
- Extremely fast and low-noise measuring amplifiers ICs.
- Adjustable to MM and MC pickups by two DIP switches.
- Input resistance switchable with 10-fold DIP switch between 12 and 47,000 Ohm (47KOhm).
- Amplification adjustable with 6-fold DIP switch from +30 dB to +70 dB.
