Frequently Asked Questions - STWM722C Skytec

How to install batteries in the handheld microphone?

Open the battery compartment cover, insert two 1.5V R6 batteries respecting polarity (+/-), then close the cover.

What to do if the microphone produces no sound?

Check that the power switch of the transmitter is ON and that the batteries are correctly installed. Also ensure that the receiver is on and the volume is sufficient. If the red indicator on the transmitter does not blink, replace the batteries.

How to adjust the gain of the bodypack transmitter?

Use a screwdriver to turn the gain adjustment: clockwise to increase gain, counterclockwise to decrease. The factory setting is at the middle position.

What is the maximum range of the system?

The maximum range is 50 metres under normal use conditions, without major obstacles.

How to connect the receiver to a mixing console?

Use either the balanced XLR output or the unbalanced 6.35mm jack output of the receiver to connect to the input of the mixing console or amplifier with an appropriate audio cable.

What to do in case of interference or radio noise?

Identify potential sources of interference (other RF transmitters) and turn them off. If necessary, use a system operating on a different frequency. Orient the antennas at 45° and keep them away from metal surfaces.

How to clean the microphone?

Use a dry cloth to clean the device. Never use liquids or chemicals, as they could damage the components.

Can multiple systems be used simultaneously?

Yes, multiple UHF systems can be used in the same area, provided each system is set to a different frequency. The frequencies are indicated on the back of each receiver.

What to do if the low battery LED lights up?

The red LED indicates approximately one hour of battery life remaining. Replace the batteries as soon as possible to avoid any audio dropouts.

Where to place the antennas for best reception?

Orient the receiver antennas at an angle of 45° from vertical. Avoid placing them near metal surfaces or obstacles. Ensure the transmitter is within line of sight of the antennas.

SYSTEM FEATURES

All UHF Series systems offer a variety of exceptional features, including:

1. Multiple System Use: Up to several UHF systems can be used in the same performance space. Each system must be set at a different frequency. (Frequency marked on the back of the receiver)

2. Simultaneous Output Use: Unbalanced 6.3mm phone plug and balanced XLR output connectors may be used simultaneously to different external devices.

3. Range: UHF Series transmitters will work at a distance of up to 50 meters from the receiver.

4. Noise Squelch: Squelch circuit analyzes signal strength and quality so that can reduce the likelihood of noise burst due to environmental RF (radio frequency) noise.

5. Low Battery Warning Light: A red light on the body-pack and hand -held transmitters warns the user that there is less than one hour of battery life left.

BODYPACK TRANSMITTER AUDIO GAIN ADJUSTMENT

The audio gain control on transmitter has been factory-at the mid-range position for best performance in most applications. This may be necessary for soft singers or talkers, or guitar or basses with low outputs.

• To Increase Gain: Rotate the transmitter gain control clockwise with the screwdriver to increase audio gain.
• To Reduce Gain: Rotate the transmitter gain control counter clockwise with the screwdriver to reduce audio gain.
  • To return audio gain to the factory setting, rotate the transmitter audio gain control to the mid position

TIPS FOR ACHIEVING MAXIMUM PERFORMANCE

• Make sure you can always see a receiver antenna from the transmitter position.
• Keep the distance from transmitter to receiver antenna as short as possible.
• Point receiver antennas away from each other at a 45 angle from vertical.
• Avoid placing the receiver antennas near metal surfaces and obstruction.
• Monitor battery fuel gauge and replace battery as soon as red light is on.
• If stacking or rack mounting receivers In a multiple-system use situation, do not allow antennas to touch or cross.
• Perform a walk-through before Performance or Presentation. If dead spots are found, adjust location of receiver. If dead sports remain, mark spots and avoid.
