The S4.4 UHF range may be switched between four frequency channels, and may be used license-free in the UK on channel 70. Systems are available with belt-pack or handheld transmitters. Beltpacks can be switched for use with a microphone or musical instrument, and are available with lapel or aerobics headband microphone. Handheld transmitters are available with dynamic or condenser capsules.
Since only four frequencies are available for use, only four S4.4 series transmitters can be used at once (if all are programmed to the same four frequencies) so the S4.4 range is appropriate for a site with up to four systems in use at one time or for where the likelihood of other users trying to use the same frequencies is considered acceptable. All the S4.4 range are supplied configured to use the standard UK Channel 70 frequencies; 863.150, 863.725, 864.150, 864.850MHz. The systems, transmitters and receivers can be supplied configured to use up to four frequencies in channels 62-64 or 67-69 on request. Please see UK Legal Radio Mic Frequency Guide. All transmitters meet fully with the requirements of ETSI 300-422/455, FCC part 74h.
Although the most inexpensive model in the Trantec range, with basic features, this is a diversity type, which compares automatically the signal between two antennae and chooses the strongest signal as the transmitter is moved about. It uses phase lock loop (PLL) quartz-controlled tuning for stability, and has both unbalanced and professional balanced audio outputs.
On the front are LEDs to show supply ‘on’, audio peak overload, and which of the two diversity channels are currently providing the signal. Radio signal strength is indicated by a bar graph of four more LEDS. Two non-detachable antenna may be swiveled for optimum positioning. On the rear is the co-axial DC power input, mute/squelch level control, screwdriver operated channel selection switch and the outputs. There is a balanced XLR connection and an unbalanced 6.35mm jack output. Both are adjusted by a level control.
