The Trantec S4.04-RX UHF receiver is a replacement desktop receiver for the S4.04 range from Trantec but it is also backward compatible with the S4.4 range which was recently discontinued.
The S4.04RX receiver can accept transmissions from 4 frequencies and these are selectable by the easy to use buttons on the front panel. The frequencies are in the channel 70 range and therefore licence free in the UK.
CH 0 receives on 863.150MHz
CH 1 receives on 863.725MHz
CH 2 receives on 864.150MHz
CH 3 receives on 864.850MHz
On the old S4.4 microphones and receivers the channel numbers were different so if you need to match up old and new just follow these instructions:
New S4.04RX receiver on channel 0 will work with old S4.4 transmitter on channel 1
New S4.04RX receiver on channel 1 will work with old S4.4 transmitter on channel 2
New S4.04RX receiver on channel 2 will work with old S4.4 transmitter on channel 3
New S4.04RX receiver on channel 3 will work with old S4.4 transmitter on channel 4
The receiver unit does not come supplied with any leads to connect to the sound system so you'll need to keep your old ones or add a new one to your basket at the checkout. It is also worth noting that the new receivers don't have a volume control like the old S4.4 so your audio equipment will need a separate control for the input you're using. If you need a more thorough explanation of this or you'd like any advice please feel free to get in touch and we'll be happy to help.
