Dbx 122 II tape noise reduction system in very good condition
Tape noise reduction system with fixed compression and de-compression ratio. S/N 110dB; Z-in: 50K; V-in:300mV; Z-out: 0,47K; Freq-range: 30-20000Hz. This apparatus must be inserted between the amplifier and the recorder.
Works with any recorder because the compression is linear in contrast to Dolby-NR or Dolby-B where the reproduction level must match the recording level.
