R5 UHF MULTI-FREQUENCY BELT-PACK IFB RECEIVER EURO MODEL OPERATING INSTRUCTIONS and trouble-shooting guide LECTROSONICS, INC. www.lectrosonics.
INTRODUCTION Thank you for selecting the Lectrosonics frequency agile, R5 IFB Receiver. The R5 is the result of extensive engineering experience with the very latest components. The design addresses the most demanding professional applications. The Lectrosonics R5 Receiver along with the companion T5 transmitter allow on-air talent to monitor program audio, and to receive cues from directors and other production personnel.
IFB Receiver GENERAL TECHNICAL DESCRIPTION The IFB R5 Receiver is comprised of a number of functional subsystems as shown in Fig 1, Control Panel and Fig 3, Receiver Block Diagram. GENERAL FEATURES The frequency agile IFB R5 FM Receiver is designed to operate with the Lectrosonics IFB T5 Transmitter and features microprocessor control of 256 frequencies of operation within each frequency block. Each block covers 25.5 MHz with 0.100 MHz frequency spacing. Up to 256 special frequencies and 0.
HEADPHONE JACK (fig. 1) On the front panel is a 3.5mm mini phone jack to accommodate a standard mono or stereo type 3.5 mm plug. The unit will drive low or high impedance earphones. The jack is also the receiver antenna input with the earphone cord acting as the antenna. The cord length is not critical but must be at least 6 inches minimum. OUTPUT DRIVE LEVEL ADJUST (fig. 2) On one side of the receiver unit is a sliding door covering an Output Max Level screwdriver adjust potentiometer.
IFB Receiver SAFETY NOTES Excessive sound levels can cause permanent hearing damage. 1. Always adjust the volume to the lowest level before listening to unknown transmissions. 2. Use the lowest reasonable level consistent with hearing safety. 3. Don’t use high sound levels in the earphone to overcome high ambient sound levels. That is absolutely foolish! Demand and use high isolation earphones. 4. Don’t expose your ears to sound levels that cause them to ring.
RECEIVER OPERATING INSTRUCTIONS Before operating a receiver, one or more IFB T5 transmitters must be placed in XMIT mode, with each transmitter set to the desired frequency and connected to a proper antenna, audio source, and power source. The transmitter fre quency block must be the same as the receiver frequency block as marked on each unit. RECEIVER NORMAL OPERATION (already programmed) 1. Plug an earphone or headset into the 3.5mm jack and set for MONO PLUG or STEREO PLUG.
IFB Receiver ERASE ALL 5 CHANNEL MEMORIES 1. With power OFF, depress the knob and turn the unit ON. Continue to hold the knob down until the LED starts rapidly blinking. The memory is now erased and the unit will go into scan/search mode. 2. Continue from step 3 above PROGRAMMING - ADD NEW FREQUENCY…. MULTIPLE TRANSMITTER SETUP When using this IFB receiver in a search mode, with two or more transmitters running at the same time, the receiver may stop on a false signal under the following conditions: 1.
TROUBLESHOOTING SYMPTOM POSSIBLE CAUSE LED NOT LIT • Battery not installed or depleted • Power switch not on. NO SOUND IN HEADPHONE • AUDIO LEVEL turned all the way down. • Headphone plug not inserted fully. • Defective headphone • Transmitter not operating. (See separate transmitter manual.) • Mono Plug /Stereo Plug switch set to wrong position DISTORTED SOUND lamps • Transmitter gain (audio level) is far too high. Check mod level on transmitter as it is being used.
