Remote control Revox B225The original remote control switch for the B225 is not only difficult and expensive to get, it has the charm of a brick, is impractical and offers little function. But even worse is the unsafe transmission protocol of the old Telefunken technology. The receiver unit in the CD player responds with errors to other infrared handset in the household and even lamps. This is the cause of abrupt shutdown of the B225 during operation or the temporarily disturbing oscillation of the digital servo circuit. The good news, with the nanocamp remote module can be used manual switch for CD players (Grundig, Philips, Marantz ... RC5) or universal switch. The transmission is not only trouble-free, it also offers a useful range of functions.
The B225 now leaves e.g. even with a solo cast in front of active loudspeakers with its second output, which can also be controlled via remote control, the separate digital-in module also offers a choice between CD playback and another source and can be compared to comparable Philips based CD players with the TDA1540 analogue converter also the title selection via the number keys of a remote control.
Special functions can also be controlled with number combinations, as some remote handset have no corresponding keys: 0.1 = StdBy / 0.2 = Source / 0.3 = Loop / 0.7 = Volume / 0.9 = Volume + / Tracknumber, Play = track selection
Plug-in module for Revox B225 48,- Euro
Installation exampleThe module has plug and socket strip to be inserted on the microprocessor board between (mouseover image).
Instead of the existing connectors, the module is plugged into the microprocessor board. A resistor to a wire bridge connects the module to the 5 volt power supply (mouseover image).
The red-marked cable bridge is interrupted to deactivate the old infrared control. The microprocessor board is then inserted with module back into the device to plug in the local plug now in the module. The infrared receiver can then be positioned. We recommend the position of the old infrared receiver behind the red window at the bottom left of the front panel.
Optional removal of the old receiving unitOn the neighboring board "Servo 2" is the now redundant old receiving unit.
For deactivation, the components shown can be removed without replacement. The square LED bulb, which lights up when the Revox is inactive, can then be used again (mouseover image).
With the adhesive pad attached, the infrared receiver on the square LED finds an optimal position. Already the servo 2 board can be plugged in again.
The B225 can be reconnected to the mains cable after the housing cover has been mounted and switched on, the remote control module initialises itself with the first switch-on, then the Revox must be briefly disconnected from the mains socket for a subsequent restart.
