Thank you for choosing a RELACART professional wireless microphone system. You have joined thousands of other satisfied customers. Our years of professional experience of design and manufacturing to ensure our products' quality, performance and reliability. Contents SET SYNC SET SYNC ①EIA-standard metal 1/2 - rack receiver chassis, antenna diversity. ②The Handheld Transmitter offers durable, ergonomic metal bodies, soft-touch controls. ③Bright and easy-to-read LCD display shows RF/AF, diversity strengths; transmitter battery level; meanwhile, can set up selective channel, frequency, mute and other working status. ④Press the "AFS"(Auto Frequency Selection) button 3S and the receiver will auto-scan and lock on to an open, interference-free frequency ⑤Press [IR] button to upload automatically the receiver frequency to the transmitter. ⑥PLL (Phase Lock Loop frequency control) design ensures transmission reliability, "NoiseLock" squelch effectively blocks stray RF. ⑦Each channel 32 selectable frequencies, dual- channel total 768 selectable frequencies. ⑧Battery life is up to 15 hours. ⑨Designed for use on professional tours, concert halls and houses of worship. Stable functions, reliable and flexible performance, easy to install. Introduction Installation: ①For better operation the receiver should be at least 3ft. 1m above the ground and at least 3ft. away from a wall or metal surface to minimize reflections. ②Attached a pair of UHF antennas to the antenna input jacks, the antenna are normally positioned in the shape of a “V” (both 45°from vertical) for best reception. ③Keep antennas away from noise sources such as computer, digital equipment, motors, automobiles and neon lights, as well as away from large metal objects. ④Keep open space between the receiver and transmitter for better reception. ⑤The transmitter should be at least 3ft. from the receiver. Connections: ①The switching power supply is designed to operate properly from any AC power source 100-240V, 50/60Hz without user adjustment. Simply connect the receiver to a standard AC power outlet, using only an IEC-type input cordset approved for the country use. Power to the unit is controlled by the front panel power switch. ②There are two audio outputs on the rear panel: an XLR microphone output and a 1/4” (6.3mm) phone jack instrument output. The two isolated audio outputs permit simultaneous feeds to two different inputs. Use the appropriate shielded audio cable for connections between the receiver and the input (s) of the mixer or other equipment. 3, Receiver Controls and Functions () Receiver Installation and Connections Figure A: UR-220S Receiver Front Panel ①Power Switch：Press power switch in 3 seconds and the receiver readouts will light. ②Infrared Data Transfer Button (SYNC): Press this button to transmit the channel data from receiver to transmitter. ③Infrared Data Transfer Window (iR): Transmit channel data from the receiver to the transmitter, so that they are in the same frequency. ④LCD Window: Liquid Crystal Display indicates control setting and operational readings. See “System setup” on page X for details. ⑤UP / DOWN Buttons: A, Press Up or Down arrow button, in conjunction with the Set button, to step through menus, select operating frequency and edit receiver function choices. B, Press Up or Down arrow button 3 seconds and the receiver will auto-scan and lock on to an open, interference-free frequency. ②SET Button: Use in conjunction with the Up / Down arrow buttons to step through menus, choose operating frequency and select receiver function options. Receiver Controls and Functions Figure B: UR-220S Receiver Rear Panel ①Antenna Input Jack: BNC type antenna connector for tuner ”B”, attached the antenna directly. ②Volume Button: To adjust the volume. ③Balanced Output Jack: XLR type connector. A standard 2 conductor shielded cable can be used to connect the receiver output to a balanced microphone level input on a mixer or integrated amplifier. ④Unbalanced Mixed Output Jack: Unbalanced Mixed Output Jack: 1…
