Trantec S4.10 Handheld System Channel 70
The S4.10 series Handheld Systemis a full featured product accommodating 4 systems out of 10 available frequencies on licence free Channel 70. This leaves space for adjacent guard band to stop interference. With an Enhanced Frequency Bank system it maximises the availability of clear unused frequencies. A simple Easy Lock system synchronises multiple transmitters to receivers.
S4.10 Handheld Transmitter
Dynamic capsule with a smooth 50Hz – 15kHz frequency response Well defined cardioid pickup pattern rejects feedback and background noise The smooth response is Ideal for additional applications such as instrument recording A switchable -10dB pad decreases sensitivity when high SPLs are encountered Stainless Steel mesh protects capsule against damage Capsule soft suspended to avoid handling noise Two stage pop filter shields capsule from Plosive sounds Fully synthesized PLL quartz tuning technology Selected operating channel automatically locks transmitter and receiver together via simple Infra Red link or can be achieved manually Squelch is automatic as the system senses the absence or weak microphone signal and mutes.
Microphone mutes when audio is not present Lower Case unscrews to reveal 1. AA battery 2. infra-red sensor 3. Channel number 4. -10dB pad switch 5. Set button selects chosen frequency Range of up to 100 metres Low Battery Alarm is shown on the receiver by a blinking LED An AA battery gives up to 10 hours of quality performance
The Microphone holder fits both 3/8 inch and 5/8 inch 27 tpi mic stands
S4.10 series Receiver
Diversity reception automatically switches between antennas A and B for best reception Up to four channels can be used simultaneously without interference due to the restricted channel space assigned to channel 70 Antennas can be set at any angle to maximise best reception. V formation is usually best Antennas plug into BNC sockets at the rear so external aerials can be substituted if reception is poor Automatic frequency scan searches for the four clearest frequencies LEDs show 1. RF reception signal strength 2. Which diversity channel is in use, either left or right 3. Lights red at -3dB audio level overload point 4. Channel identity 5. Transmitter battery status alert when transmitter battery is low Signal Squelch automatically mutes when carrier is not present Simple Sync locking procedure. Manual and automatic. Locks chosen transmitter to receiver Audio output level adjustable Audio outputs, XLR balanced and Jack unbalanced.

Channel 70 is Licence free
Some equipment that is manufactured can tune into frequencies that do not require a licence to operate. There are several licence exempt areas for PMSE use.
The UHF licence exempt range is 863.100-864.900 MHz. This is within Channel 70. The power on channel 70 is limited by legislation to 10mw for handheld microphone transmitters. There is no limitation to how many frequencies can used in this channel as long as users stay within the confines of the band. On average users would probably be able to use four units at one time.
There are currently no plans to remove access to Channel 70; it will continue to be licence exempt for PMSE users.
Channel 70 is adjacent to use of mobile in the 800 MHz band. There should not be any interference however this is the risk taken with the licence exempt channels.
