Surpassing the requirements of German Hi-Fi standard DIN 45 500, the 560 Royal was a stereo tape recorder with interchangeable tape heads and a myriad of trick recording facilities .

An inbuilt 10 watt per channel amplifier drove twin internal speakers and the recorder featured four tape speeds, from 15/16 ips to 7½ ips.

The 'Tape Tension Comparator', featured on this recorder, was developed by Uher to maintain constant tape movement.


It utilised two sensing levers either side of the tape slot which matched the tape tension with the constant tension of a coiled spring, thus assuring the least tape damage possible even when using reels of differing sizes.

Another standard feature was slide projector synchronizing ("Dia-Pilot") enabling the recording of cueing signals for automatic slide projectors.

Separate input controls allowed stereo mixing of recordings and the amplifier was able to be used with the deck mechanism switched off.
