Audio Research VSi55 - Begagnad rörförstärkare

Beskrivning

Begagnad integrerad rörförstärkare från Amerikanska Audio Research. Rören är kontrollmätta av oss och har ca 85-90% kvar av nyprestanda. Fjärrkontroll och manual finns och även låda, så vi kan skicka fraktfritt inom Sverige.

Power output
50 watts per channel continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 1% at 50 watts, below .05% at 0.1 watt. Approximate actual power available at “clipping” 52 watts (1kHz). (Note that actual power output is dependent upon both line voltage and “condition” i.e.: if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not very critical.)
Power bandwidth
(-3dB points) 12Hz to 90kHz
Frequency response
(-3dB points at 1 watt) 1.0 Hz to 100 kHz
Input sensitivity
0.5V RMS Single-ended for rated output. (32 dB gain into 8 ohms)
Input impedance
50K ohms Single-ended
Output taps
8 ohms, 4 ohms.
Output regulation
Approximately 1.5 dB 8 ohm load to open circuit

Hum & noise
Less than 0.14mV RMS - 103dB below rated output (IHF weighted, input shorted)
Power supply energy storage
Approximately 166 joules
Power requirements
100-125VAC 60Hz (200-250VAC 50Hz) 320 watts at rated output, 500 watts maximum, 205 watts at "idle". 0.5 watts power off.
