    • Line Out: 2xCinch, 400 mV/800 Ohm


Technical Data

  • Audio heads: 1 recording head made of permalloy, 1 playback head made of permalloy, 1 ferrite double gap erasing head.
  • Recording system: alternating current premagnetization
  • Premagnetization frequency: 80 kHz

Metal: 30 Hz ~ 19 kHz, +/- 3dB ; 20 Hz ~ 20 kHz (DIN)

  • Distortion factor: n.a.

Signal-to-noise ratio: (signal level = full scale; CrO2 band)

    • with Dolby C noise reduction: 74 dB (CCIR)
    • with Dolby B noise reduction: 66 dB (CCIR)
    • without noise reduction: 57 dB (A-weighted)
  • Auto Reverse: no
  • Title search: yes
  • Dolby HX PRO: Dolby B, Dolby C
  • MPX Filter: yes
  • Fader: No
  • Pitch control: No
  • CD Direct Recording: No


Special Features

  • Manual Bias Setting
  • Memory stop, repeat function<->AB
  • real time counter, switchable to normal tape counter
  • built-in IR receiver (sensor)
  • quartz controlled direct drive (only a few devices of the 90s had this)

Occurring errors:

  • no sound, no recording:C619, C620, C621, C622 & C624 -> replace 1000uF-10V
  • Permanent magnet on capstan can come loose, especially after transport. Leads to fast grinding noises! All DD Drive AR350
  • Gear of rewind motor can break/ crack! Pos. No. 130/ ET. No. RDG0034 -> no longer available
  • Trembling in the sound: Lubricant of the winding plate axles flocculates! Re-lubricate with graphite grease
  • Clay leaks: Spring of pressure roller gives way. Item no. 120-1/ ET. No. RUW140ZC -> no longer available

For your consideration Due to age, the plastic elements in the drive become increasingly brittle and break => irreparable.

Remarks[edit]

  • The drive is without belt. A permanent magnet is attached to the capstan flywheel, which is driven by an electromagnetic field.
  • The RS-BX626 was released in October 1992, replacing the RS-BX606. It was replaced by the BX 646, which no longer had a direct drive.

Other models in the same series:
