수신기 배치
Place the CR277 receiver on a stable, flat surface, away from potential sources of interference such as computers, large metal objects, or other wireless devices. Ensure adequate ventilation around the unit.
수신기 연결
- Connect the included power adapter to the DC input on the rear panel of the CR277 receiver and then to a suitable power outlet.
- Connect the receiver's audio outputs to your mixer, amplifier, or PA system. You can use either the two independent 1/4-inch outputs (one for each channel) or the single 1/4-inch mix output.
- Extend the tuned molded antennas for optimal signal reception.
Battery Installation (HT7 Transmitters)
Each HT7 handheld microphone transmitter requires one 9-volt battery for operation. To install the battery:
- Unscrew the bottom section of the microphone handle.
- Insert a fresh 9-volt battery, observing the correct polarity (+/-).
- Screw the bottom section back onto the microphone handle until secure.
Each transmitter is designed to operate for approximately 12 hours on a single 9-volt battery.
작동 지침
전원 켜기/끄기
- 수화기: Press the POWER button on the front panel of the CR277 receiver to turn it on. The power indicator will illuminate.
- 송신기: Slide the ON/OFF switch on each HT7 microphone transmitter to the 'ON' position. The power/battery indicator on the transmitter will light up.
레벨 조정
The CR277 receiver features independent level controls for each channel (Ch U1 and Ch U2). Adjust these knobs to set the desired output volume for each microphone. Monitor the multi-segment RF level and peak audio indicators to ensure optimal signal strength without clipping.

마이크 사용
Hold the HT7 microphone approximately 2-6 inches from your mouth for best vocal pickup. The Q7 dynamic microphone element is designed for clear and articulate sound reproduction.
스켈치 제어
The CR277 receiver includes squelch control for each channel. This feature helps to eliminate unwanted noise when the transmitter signal is weak or absent. Adjust the squelch knob clockwise to increase the squelch threshold, reducing background noise. Adjust it counter-clockwise to decrease the threshold, allowing weaker signals to pass through.
유지
청소
To clean the receiver and microphones, use a soft, dry cloth. For stubborn dirt, a slightly damp 천을 사용할 수 있지만 내부 부품에 습기가 들어가지 않도록 하십시오. 연마성 세척제나 용제를 사용하지 마십시오.
배터리 교체
Replace the 9-volt batteries in the HT7 transmitters when the power/battery indicator on the microphone begins to dim or when audio quality degrades. Always use fresh, high-quality alkaline batteries for optimal performance and battery life.
저장
When not in use for extended periods, remove the batteries from the transmitters to prevent leakage. Store the system in a cool, dry place, away from direct sunlight and extreme temperatures.
