GETTING STARTED

Step 1:
Put 2 batteries into each of your transmitters. The handheld takes 2 AA batteries and the battery compartment can be located by unscrewing the bottom of the handle. The beltpack takes 2 AA batteries and the compartment can be located by swinging open the door. See diagrams on pages 10 and 11.
Step 2:
Attach the two antennae to the back of your receiver. Attach by screwing onto the receiver in the proper location. See a picture of your receiver on pages 6, 8, or 9 for help with locating the proper location.
Step 3:
Connect your sound system to your wireless microphone system using either 1/4″ or XLR cables but not both at the same time. You will need to attach 1 XLR cable for each transmitter that you will be operating. For all receivers, when opting to use a 1/4″ cable (instead of XLR cables) then only one 1/4″ cable needs to be used per receiver regardless of how many transmitters you are operating with that receiver. Generally a cleaner more clear sound can be attained by using XLR cables. We highly recommend the use of XLR cables instead of a 1/4″ cable with your system.
Note:
Generally a cleaner more clear sound can be attained by using XLR cables. We highly recommend the use of XLR cables instead of a 1/4″ cable with your system.

Step 4:
Plug the wall wart power supply into the back of your receiver and then into an electrical outlet.
Step 5:
Power on your receiver using the power switch.
Step 6:
Power on your transmitter.
Handheld: Use the power button to power on the device. Beltpack: Power on using the button located on the central panel of the beltpack. Push power button for 3 seconds. See diagram on page 11.
Step 7:
Now you must sync your transmitter and receiver to the same frequency or channel. By using the receiver controller on your receiver you can toggle through the various receiver
settings and choose the IR sync mode. The receivers allow you to access IR sync mode by simply hitting the button on your receiver that says “IR SYNC”.
Note:
If you are going to be using more than one transmitter at a time then each transmitter must be set to a different frequency or channel. You can use the receiver controller to select different frequencies (or channels) for additional transmitters. Choose a frequency or channel for a specific receiver channel and sync the next transmitter to a different frequency or channel than the previous transmitter(s). Refer to the page in this manual that gives instructions for your specific receiver for detailed instructions.

Step 8:
Locate the IR sync window on the receiver. Look for the letters IR on your receiver to locate the window. Please see pictures on pages 6, 8, and 9 to help locate the IR sync window location.
Handheld Transmitter:
Point the small IR window on the front of your transmitter facing toward the IR sync window on the receiver at a distance of about one-half inch or less. Hold the handheld in this position. When properly aligned the handheld should automatically change frequency to match the frequency of the receiver. See page 10.
Beltpack Transmitter:
Open the compartment where the batteries are stored. Align the red IR sync window on your beltpack to that on your receiver to automatically sync the transmitter to the frequency of the receiver. See page 11.
Note:
Frequency display can be found on page 10 for the handheld and page 11 for the beltpack.
Step 9:
Make sure the volume knobs on your receiver are turned up to the desired level.
Step 10:
Your wireless microphone system should now be operational as long as all your sound equipment is set up properly as well. When you are finished make sure to power off your transmitter and receiver.
For detailed instructions regarding using the IR sync function of your receiver please refer to the IR sync instructions that follow for the specific system that you purchased.

HELPFUL DIAGRAMS

Four Microphone System

*Must use XLR cables to control channels independently.
Product may differ from photos

Four Microphone System

A. Receiver Controller – Use the receiver controller to toggle through options, select channels (A through D) and set the frequencies of the transmitters.
B. Group Select – By selecting this option via the receiver controller you can select a group of preset frequencies for all 4 of your transmitters/receiver channels. Each transmitter would still need to go through the IR Sync function if not already in Sync.
C. IR Sync – This mode allows you to IR Sync your transmitters individually with your receiver. See the detailed explanation below.
Note: Using Group select will pick four different preset frequencies for each of your transmitters. You will still need to use IR Sync to sync each transmitter with the receiver.
Note: It is possible to use one 1/4″ cable to for all 4 channels. However, a cleaner signal may be obtained if you use 4 individual XLR cables. Using XLR cables will also allow the sound man to adjust each of the transmitter’s sound levels individually when away from the receiver with the use of a mixing board.
Note: It is suggested that the transmitters have at least 3 or more full frequencies of distance between each other to help prevent interference with each other. For example: If the first transmitter is on 471.000 MHz then make sure that the second transmitter is at least on 474.000 MHz or greater distance from the selected frequency of the first transmitter.

Other Functions:
Volume Control – The volume of each channel can be adjusted using the individual volume control knobs.

Further Instructions Regarding IR Sync Mode:

Step 1.
Make sure all other microphone receivers and transmitters in the room are turned off except for the receiver and transmitter you are trying to sync.
Step 2.
By using the receiver controller select a receiver channel for which you would like to sync a transmitter and access sync mode. You can use one channel per transmitter. One transmitter can sync to A, the second can sync to B, the third to C, and the fourth transmitter can sync to D.
Step 3.
After completing the previous step the receiver should now be ready to sync for the channel you have chosen. Now hold the powered transmitter up to the receiver with the IR window of the transmitter facing toward the “IR” window on the receiver. See the diagram on the preceding page to find the location of your receiver. Also, see pages 10-12 for more information.
Step 4.
After successfully completing the IR Sync procedure repeat the same procedure for all 4 transmitters choosing a different channel (A, B, C or D) for each transmitter. Each transmitter must be on a different frequency. If you have two receiver channels on the same frequency then change the frequency or “channel” for one transmitter.

Two Microphone System

AVTHHT1 Handheld Transmitter

AVTBPT1 Beltpack Transmitter

Hold power button for 3 seconds to power on.

How to change the AF signal (sensitivity) level.
Press the Mode button. When a frequency is blinking you can press the “Mode” button again. AF bar will blink. This allows you to set the sensitivity of the mic at different levels (low, medium, high). Usually, this should be Medium. It is possible to lower or upgrade the sensitivity.
Note: This is not the recommended way to adjust volume.

How to set frequency of transmitter without using a receiver.
Beltpack: Press Mode button solftly. Then use buttons to select desired Frequency when the frequency is blinking. Stop using arrow buttons once you are on the selected frequency.
Note: You should usually use the receiver sync process to change the frequency of the transmitter. Setting the frequency of the belt pack independently of the receiver may result in malfunction.

IR SYNCING

Four Microphone System is shown below. See pages 6-9 to find the IR Sync location for the receiver you have purchased.

IR Window on the transmitter (handheld or belt pack) needs to be within 1/2″ of the IR Sync Window on your receiver in order to sync properly. See photo illustrations above.
