Re: Hotel Panel Radios
Sorry, should have been clearer. All the radio feeds to the bedhead unit were at AF, using telephone twisted pairs. The multiple Tuner/Amplifier was somewhere in the lobby in an inaccessible cupboard normally.
100V line was used for the hotel PA, but not for the audio to the bedhead units, due to having to use multiple step-down transformers and the undesireability of having 100v near the customer.
