3. Product Overview

Familiarize yourself with the main components of your SubZero Wireless Microphone System.

System Components

3.1 Receiver Unit

The receiver unit processes the wireless audio signals from the bodypack transmitters. It features independent volume controls for each channel (A and B) and output connections for integration with your audio system.

3.2 Bodypack Transmitters

Each bodypack transmitter sends the microphone's audio signal wirelessly to the receiver. They are compact and designed to be worn discreetly.

3.3 Lavalier Microphones

Small, discreet microphones designed to clip onto clothing, ideal for hands-free operation.

3.4 Headset Microphones

Head-worn microphones that provide consistent microphone placement for clear audio, suitable for active performers.

4. Setup Guide

4.1 Unpacking

1. Carefully open the carry case and remove all components.
2. Inspect all items for any signs of damage. If any damage is found, contact your retailer immediately.

4.2 Receiver Connection

1. Place the receiver unit on a stable, flat surface, away from potential sources of interference.
2. Extend the receiver antennas vertically for optimal signal reception.
3. Connect the included 12V DC power supply to the receiver's 'DC INPUT' port and then plug it into a suitable power outlet.
4. Connect the receiver's 'MIX.OUT' (6.35mm jack) or 'BALANCE OUT' (XLR) ports to your mixer, amplifier, or audio interface using the provided 6.35mm jack cable or appropriate XLR cables (not included).

4.3 Bodypack Battery Installation

1. Slide open the battery compartment cover on each bodypack transmitter.
2. Insert two 1.5V AA batteries into each bodypack, ensuring correct polarity (+/-).
3. Close the battery compartment cover securely.

4.4 Microphone Connection

1. Connect either a lavalier microphone or a headset microphone to the 3.5mm input jack on each bodypack transmitter. Ensure the connector is fully inserted.
2. Secure the lavalier microphone to clothing (e.g., lapel) or position the headset microphone comfortably on the user's head, with the microphone element positioned near the mouth.

5. Operating Instructions

5.1 Powering On/Off

1. Receiver: Press the power button on the receiver unit. The power indicator light will illuminate.
2. Bodypack Transmitters: Press and hold the power button on each bodypack transmitter until the display illuminates.
3. To power off, press and hold the power button on each unit until it shuts down.

5.2 Volume Adjustment

1. Adjust the 'VOLUME A' and 'VOLUME B' knobs on the receiver to control the output level of each microphone channel independently.
2. Start with the volume low and gradually increase it to a comfortable listening level, avoiding feedback.

5.3 Frequency Information

The SubZero VOXLINK-2FL system operates on a fixed UHF frequency of 863.7MHz. This fixed frequency ensures stable performance within its operating range. Please note that only one fixed unit at a time can be used in the same vicinity to avoid interference.

6. Maintenance

6.1 Cleaning

• Wipe the surfaces of the receiver and bodypacks with a soft, dry cloth.
• Do not use abrasive cleaners, solvents, or chemical sprays, as these can damage the finish or internal components.
• For microphones, gently clean windscreens if necessary.

6.2 Storage

• When not in use for extended periods, remove batteries from the bodypack transmitters to prevent leakage.
• Store the system in its original carry case in a cool, dry place, away from direct sunlight and extreme temperatures.

7. Troubleshooting

If you encounter issues with your SubZero Wireless Microphone System, refer to the following common problems and solutions:

No Sound Output

• Ensure all units (receiver, bodypacks) are powered on.
• Check that the receiver's volume knobs are turned up.
• Verify that the receiver is correctly connected to your mixer/amplifier and that its input is selected and volume is up.
• Check batteries in bodypacks; replace if low or depleted.
• Ensure microphones are securely connected to bodypacks.

Interference or Dropouts

• Ensure the receiver antennas are fully extended and positioned vertically.
• Move the receiver closer to the transmitters, within the 50-meter operating range.
• Ensure there are no large metal objects or other wireless devices operating on similar frequencies nearby.
• Remember that only one fixed unit of this model can be used in the same vicinity at a time.

Short Operating Range

• Check bodypack battery levels. Low batteries can reduce range.
• Ensure line-of-sight between transmitters and receiver is maintained as much as possible.
• Avoid placing the receiver behind large obstacles or in enclosed spaces.
