UHF Wireless Digital Hybrid TM Receiver GENERAL TECHNICAL DESCRIPTION The UCR511 is a portable, high performance, tripleconversion, frequency synthesized, UHF receiver fully compatible with all Lectrosonics 500 series transmitters (and some other transmitter types – see Compatibility Modes for details.) The RF performance is extremely stable over a very wide temperature range, making the UCR511 perfectly suited to the rough environmental conditions found in the field.
UCR511 (Surface Acoustical Wave) filters. The 244 MHz SAW filters combine sharp tuning, constant group delay, wide bandwidth and excellent temperature stability, far supe rior to conventional LC filters. The 244 MHz first IF signal is converted down to 10.7 MHz, filtered through two ceramic filters for sharp selectivity, then converted to 300 kHz.
UHF Wireless Digital Hybrid TM Receiver algorithm remains undetectable under most circumstances. RF-CONTROLLED DIGITAL NOISE FILTER In addition to SmartNRTM, the UCR511 contains an RF sensitive variable frequency filter, which reduces high frequency response under extremely weak RF condi tions. This filter does nothing until the RF signal strength drops below 3 uV at which point it begins to roll off high frequencies.

UCR511 In the two user programmable frequency groups, up to 16 frequencies can be programmed per group. Note The Tuning Setup Screen only selects the tuning mode (NORMAL or Group Tuning) and not the operating frequency. Actual operating frequencies are chosen through the Frequency Window. If NORMAL tuning mode is selected, the SEL Up and Down buttons select the operating frequency in single channel (100 kHz) increments and the MENU+Up and MENU+Down shortcuts tune in 16 channel (1.6 MHz) increments.

The display will switch to the SCAN WINDOW and start scanning immediately. Data gathered during a scan is stored until it is purposely erased or the power is turned off.
UCR511 ANTENNA USE AND PLACEMENT “dropout.” A dropout sounds like either audible noise (hiss), or in severe cases, may result in a complete loss of the carrier and the sound when the transmitter is positioned in certain locations. A UHF dropout normally sounds like a very brief “hiss” or a “swishing” sound. Moving the transmitter (or the receiver’s antennas) even a few inches will change the sound of the dropout, or eliminate it.
UHF Wireless Digital Hybrid TM Receiver INSTALLATION AND OPERATING INSTRUCTIONS 1. Install a fresh battery or connect an external power source to the UCR511 and attaach the antennas. 2. Unless frequency settings have been previously assigned, scan for an open frequency and set both the receiver and transmitter to that frequency. (See Finding Clear Frequencies.) 3. Connect the audio cable to the Receiver Audio Out XLR jack. 4. Set the Power ON/OFF switch to ON and verify that the LCD panel activates. 5.

UHF Wireless Digital Hybrid TM Receiver TO REPLACE THE BATTERIES Lift and open the bottom battery door cover with your thumb, rotate the door until it is perpendicular with the case and allow the batteries to fall out of the compart ment into your hand. It is difficult to install a battery backwards. Observe the large and small holes in the battery contact pad before inserting new batteries.
UCR511 Frequency Coordination Intermodulation interference is a problem constantly lurking in the background, especially when working in environments were multiple productions are taking place simultaneously in relative close proximity. In these cases, proper frequency coordination is a must. There are basically three methods coordinate frequencies: labeled A and B and C and D, and correspond to the factory set frequency groups (Groups A, B, C and D) described in the Tuning Setup Screen.

UCR511 frequencies in Row 2 Block 21 are compatible. However, frequencies in Row 1, Block 21 are not compatible with the frequencies in Row 2, Block 21. If possible, it is highly recommeneded to choose frequencies that are in the same row and same group. For example, stick with frequencies in Row 1 Group A, or Row 2 Group D rather than choosing frequencies from Row 1 Groups A and B. Rule No. 3 Some frequencies in adjacent blocks are compatible and some are not.

Turn the receiver off, remove the cause of the overload and turn the receiver back on. Wrong polarity power source. The external DC in requires POSITIVE to be on the center pin. Battery may be low. Try a fresh battery Version message shows DSP or COM. This indicates an internal error. Please contact the factory for assistance.
UHF Wireless Digital Hybrid TM Receiver long. UHF helical antennas may be shorter, but are often less efficient. No RF Signal Make certain frequency switches on transmitter match the receiver frequency setting. Check battery in transmitter AUDIO SIGNAL QUALITY Poor signal to noise ratio Transmitter gain set too low The noise may not be in the wireless system. Turn the transmitter audio gain all the way down and see if the noise remains.
