|The S4.04-BTX (S4.04-BTX-EB-GD5) is a beltpack from the Trantec S4.04 range. The beltpack unit is supplied without any microphone and is a direct replacement for a lost or damaged unit saving you the cost of purchasing an entire new system.
The microphone will work with the old S4.4 systems too and has the following set of channel 70 frequencies:
CH 0 transmits on 863.150MHz
CH 1 transmits on 863.725MHz
CH 2 transmits on 864.150MHz
CH 3 transmits on 864.850MHz
All of these frequencies are licence free in the UK.
Please note if you're using this as a replacement beltpack for an older S4.4 system then you will notice that the channel selectors are numbered 0 through to 3 on the new S4.04 kit but numbered 1 through to 4 on the old S4.4 equipment. This is not an issue although you do need to match up the correct frequency otherwise it won't work.
New S4.04 transmitter on channel 0 will work with old S4.4 receiver on channel 1
New S4.04 transmitter on channel 1 will work with old S4.4 receiver on channel 2
New S4.04 transmitter on channel 2 will work with old S4.4 receiver on channel 3
New S4.04 transmitter on channel 3 will work with old S4.4 receiver on channel 4
The S4.04-BTX transmitter now takes a single AA battery and this will give you an expected usage time of 10 hours.
The input into the transmitter is still a 3.5mm jack to allow connection of the old and new microphones such as the MIC-LP2
