SRc5P and SRc Dual Receivers Mounting and Orientation A variety of accessories are available to enable various mounting options. For maximum operating range, the antennas should be vertical and above the camera and other equipment. The AMJ Rev. A antenna is jointed so the whips can be oriented vertically.
UHF Digital Hybrid Wireless® AMJ Rev. A Jointed Antenna The AMJ antenna is a general purpose design for any Lectrosonics receiver or transmitter with a standard SMA connector. The hinged joint pivots in both directions for positioning the whip at any desired angle.
SRc5P and SRc Dual Receivers LCD Main Window Receiver 1 Receiver 2 RF Levels Diversity Activity Audio Level Pilot Tone Indicator The Main Window displays information concerning the condition of the Pilot Tone, antenna phase, RF and audio signal levels and battery conditions for both the receiver and the associated transmitter.
UHF Digital Hybrid Wireless® Main Window The appearance of the LCD Main Window will change according to which diversity mode is selected: • SWITCH (2-channel mode) splits the screen to indicate activity and levels on both receivers and transmitters. • RATIO combines the audio outputs of both receivers to deliver a single audio channel. With the DIV MODE set to SWITCH, two audio channels will be displayed. With the DIV MODE set to RATIO, a single audio channel will be displayed.

UHF Digital Hybrid Wireless® Menu Item Descriptions LEVEL This setup screen displays the audio output level of the receiver in dBu when the transmitter is fully modulated. Press the MENU/SEL button to toggle between receiver 1 and receiver 2. Use the UP or DOWN buttons to change the level. Range is from -50 to +5 dBu in 1 dB steps. Press the BACK button to leave this screen.
SRc5P and SRc Dual Receivers TUNING In addition to the NOR (normal) mode, this screen also allows Selection of one of four factory pre-selected frequency groups (Groups a through d) or two user programmable frequency groups (Groups u and v). • NOR allows selection of all 256 frequencies that the receiver will tune. Each press of the UP or DOWN button will step in 100 kHz increments to the next frequency. • a, b, c, d sets the receiver to tune only factory preselected frequencies, up to eight in each group.
UHF Digital Hybrid Wireless® PHASE This setup screen allows the audio output polarity to be inverted to match other microphones or audio sources. TXBAT • AA - Transmitter uses a AA alkaline battery. • AAL - Transmitter uses a AA lithium battery (not rechargeable). • AAT - Transmitter uses an alkaline, lithium or rechargeable AA battery. Monitor the battery status with the timer in the receiver. • LB - Transmitter uses a Lectrosonics LB-50 rechargeable battery.
SRc5P and SRc Dual Receivers Finding Clear Frequencies with SmartTuneTM SmartTune is the easiest and fastest way to scan the local RF spectrum and find clear operating frequencies. The receiver will scan through its tuning bandwidth and automatically find “empty” areas within the tuning range that have little or no RF energy. The receiver will then be set to a frequency within an empty area and prompt you to continue or use the IR function to sync to a transmitter.
UHF Digital Hybrid Wireless® Finding Clear Frequencies with Manual Scanning Scan Window Receiver 1, dashed line Zoom View Window Receiver 2, solid line Block 26 BD RF activity level Freq in hex Cursors blink to indicate the currently selected receiver Cursor (center bar) Block 25 C7 Press both UP and DOWN arrows on control panel to switch to the Zoom View Press the BACK button to return to the Scan View Window First, turn off all of the transmitters you intend to use with the receiver.
SRc5P and SRc Dual Receivers Pre-coordinated Frequencies NOTE: As the spectrum has become more congested, interference from external sources has become common. As a result, the frequencies provided in these pre-coordinated groups may or may not be 100% usable in some locations. Interference from external sources may appear as direct signals, or may mix with the pre-coordinated frequencies and generate new RF signals through IM (intermodulation).
UHF Digital Hybrid Wireless® Frequency Coordination IM (intermodulation) is a process of two or more RF signals mixing in any stage in the transmitter or receiver that generates another RF signal. If this new signal happens to land on a carrier, IF or oscillator frequency you may have interference problems that affect range or audio quality. The possible combinations also include odd and even order harmonics of the carriers. Feel free to contact the factory if you need help in coordinating frequencies.
SRc5P and SRc Dual Receivers Troubleshooting Symptom Possible Cause INITIAL POWER ON LCD display not active or lit External power supply disconnected or inadequate. Wrong polarity power source. The external power input jack requires POSITIVE (+) to be on the center pin. Battery gets warm and doesn’t work. Version message shows DSP or COM This indicates an internal error. Please contact the factory for assistance.
UHF Digital Hybrid Wireless® Symptom Possible Cause ANTENNAS AND RF SIGNAL STRENGTH RF Level is weak No RF Signal AUDIO SIGNAL QUALITY Poor signal-to-noise ratio Receiver may need to be moved or reoriented. Antenna on transmitter or receiver may be defective or poorly connected - double check antennas. Improper length of antenna, or wrong antenna on transmitter or receiver. UHF whip antennas are generally about 3 to 5 inches long.
