IFB Transmitter GENERAL TECHNICAL DESCRIPTION The T5 IFB Transmitter is comprised of a number of functional sub-systems as shown in the block diagram below. GENERAL The T5 is designed to operate with the Lectrosonics R5 IFB Receiver and features microprocessor control of 256 frequencies of operation within any one of at least thirteen frequency bands.

ANTENNA At UHF frequencies, where wavelengths and antennas are shorter than at VHF frequencies, a resonant length antenna is preferred. The antenna on the T5 consists of a flexible 1/4 wavelength bronze cable, detachable via a connector. POWER DELAY There is a 5 second power on delay to prevent audio thumps when switching from XMIT to TUNE or from TUNE to OFF.
When the highest or lowest frequency is reached, the unit will wrap around and continue in the same direction at the other end of the range. The T5 will “remember” the last channel used when powered off and will come on at that frequency.
RTS2 IFB Transmitter ANTENNA T5 Rear Panel XLR JACK Standard XLR female jack will accept a variety of input sources depending on the MODE switches. The pin functions can be changed to suit the source depending on the** positions of the MODE switches. For detailed information on the MODE switches see the INSTALLATION AND OPERATION section.
IFB Transmitter INSTALLATION AND OPERATION 1) Pin 1 of the XLR input jack is normally tied directly to ground inside the unit. If a floating connection is desired, move the ground lift jumper inside the unit. (See next page for the location of the ground lift jumper.) 2) Set the MODE switches on the rear panel to match the specific input source to be used.
GROUND LIFT JUMPER The T5 transmitter is shipped with pin 1 of the XLR input connector tied directly to ground. If a floating input is desired, a ground lift jumper is provided. This jumper is located inside the unit on the PC board near the rear panel XLR jack.
