4. Setup

4.1 Initial Connection

1. Connect the antennas to the ANT-A and ANT-B ports on the rear of the receiver.
2. Plug the AC adapter into the DC INPUT on the receiver and connect it to a power outlet.
3. Connect the receiver's MIX OUT or BALANCE OUT (XLR) to your mixer, amplifier, or speaker system.
4. Turn on the receiver by pressing the POWER button.

4.2 Powering On Transmitters

Each gooseneck microphone has an integrated transmitter. To power on, locate the red power button on the transmitter unit and press it. The display on the transmitter will illuminate.

4.3 Charging Transmitters

The system includes a charging cable with two lines, allowing you to charge both transmitters simultaneously via the charge socket on each transmitter. The receiver also has a USB charge output for convenience.

4.4 Frequency Change and Pairing (Syncing)

To change the frequency and pair the microphone transmitters with the receiver, follow these steps:

1. Boot up the D-333T Receiver.
2. Boot up the Saxophone Microphone (Transmitter).
3. On the receiver, long press the 'Lock' button to unlock the system.
4. Rotate and press the 'SETUP' knob to choose the desired Group (GR) and Channel (CH).
5. Once the desired GR/CH is selected, long press the 'IR' button on the receiver to send out the IR signal. The IR light on the front will start flashing.
6. Position the IR window on the transmitter (located on the underside, facing the mic when assembled) about an inch away from the receiver's IR light.
7. The transmitter will synchronize with the receiver, and the IR light on the receiver will stop flashing once successful.

This process ensures your microphone is operating on the selected frequency and is properly linked to the receiver.

6. Maintenance

6.1 Cleaning

Wipe the receiver and microphone units with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the microphone capsule is free from dust and debris.

6.2 Battery Care

The transmitters use Lithium Polymer batteries. To prolong battery life:

• Fully charge the batteries before first use.
• Avoid completely draining the batteries regularly.
• Store the units in a cool, dry place when not in use for extended periods.

7. Troubleshooting

7.1 No Sound or Signal Loss

• Check Power: Ensure both the receiver and transmitters are powered on and have sufficient battery charge.
• Verify Connections: Confirm all cables (power, audio output) are securely connected to the receiver and your audio system.
• Frequency Sync: If you have multiple units or experience signal issues, re-sync the transmitter with the receiver using the IR pairing method described in Section 4.4. Ensure the IR window on the transmitter is properly aligned with the receiver's IR light during sync.
• Frequency Conflict: If using multiple wireless units, ensure each transmitter/receiver pair is on a unique group and channel. Operating two transmitters on the same frequency will cause interference and prevent proper function. If this occurs, turn off all units, then power on one receiver and its matching transmitter, change its frequency, and then repeat for other units.
• Obstructions: Wireless signals can be affected by physical obstructions (walls, large metal objects, human bodies) or other wireless devices. Try to maintain a clear line of sight between the transmitter and receiver.
• Range: Ensure you are within the effective operating range of the system.

7.2 Unwanted Echo Effect

If you experience an unwanted echo effect, it may be enabled in the receiver's settings. Navigate to the 'Effects' menu (as described in Section 5.2) and adjust the 'Echo.Vol' parameter to 0 or a lower desired level.
