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.

HT-300 / BP-300B Transmitter Circuit Description Power supply for the whole electric circuit is offered by two group voltage. One is 5V DC voltage generated by electric circuit (U2, Q3, D5) after battery 3V voltage is sent to this circuit for voltage-step up through power switch(Q4, Q15). The other one is 3.3V voltage generated by voltage regulator (U1). Microphone audio signal enhanced by prime amplifier (U2) is sent to gain dynamic amplifier (U1,U7) for processing. After processed, the signal is sent to VCO (D7) through low-pass filter (U3) and modulated with PLL(U6), PLL frequency standard(X2-8MHz,Q6), local oscillation signal generated by low-pass filter(R78,C68,C67,R81) and VCO(D6,Q8,Q9). Then audio RF signal after modulated is sent to buffer amplifier (Q7,Q14) and power amplifier(Q13) for amplifying. After amplified, it is sent to low-pass filter(L9,L10,C87,C88) to filter the high harmonic and output to antenna for transmission. MCU(U5), switch S1(POWER) and Infrared receiving module(IR1) is an operation which receives Infrared synchronized signal from receiver, and controls LCD display. MCU(U5) controls PLL(U6) working frequency according to the frequency data operated. Meanwhile, MCU(U5) will test battery voltage and auto-cut off power switch(Q4,Q15) when the voltage is over-low.
