Imtuvo išdėstymas
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.
Imtuvo prijungimas
- 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.
Naudojimo instrukcijos
Maitinimo įjungimas/išjungimas
- Imtuvas: Press the POWER button on the front panel of the CR277 receiver to turn it on. The power indicator will illuminate.
- Siųstuvai: Slide the ON/OFF switch on each HT7 microphone transmitter to the 'ON' position. The power/battery indicator on the transmitter will light up.
Lygių reguliavimas
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.

Mikrofonų naudojimas
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.
„Squelch“ valdymas
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.
Priežiūra
Valymas
To clean the receiver and microphones, use a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, but ensure no moisture enters the internal components. Do not use abrasive cleaners or solvents.
Baterijos keitimas
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.
Sandėliavimas
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.
