Receiver Installation:
1. Mount the receiver in the location where it will be used permanently. Affix the racking
bracket and mount to your digital podium or racking unit as necessary.
2. Attach the receiver’s antenna.
3. Set the Volume level somewhere near the middle setting.
4. Attach the power adapter to the receiver and connect it to a power source.
5. Turn the receiver’s power switch to the ON position.
6. The status window should light and the current operating channel will be displayed.
System Installation:
1. The receiver’s output must be connected to your audio system’s amplifier or mixer.
2. Depending on the connectivity of your system you may use the Balanced or Unbalanced
output to make the connection.
*** It is best to install the receiver and mixer/amplifier near one another. Lengthening the cable
run between devices increases the chance for audio distortion.
INSTALLATION

10
www.barosnt.com
Hand Mic Installation:
1. Remove the battery cover and install the 2 x AA 1.5V batteries supplied with your
product. Be sure to install them according to the +/- symbols denoted on the battery
case.
2. Turn the power switch to the ON position and view the status window. If the batteries are
providing ample power, the status window will display the current channel. If the
batteries are weak and need to be charged or replaced, “LO” will be displayed in the
status window. If the batteries provide no power, the status window will not illuminate and
they should be charged or replaced.
3. If the batteries are sufficient, confirm the microphone’s current operating channel. Note
whether it matches the operating channel currently displayed by the receiver.

11

Setting the Volume:
1. You can set the Volume using the Volume adjustment knob.
2. The optimal setting is for the indicator to be set at the 12 o’clock position, half way
between the MIN and MAX settings.
3. If not already matching, test the audio levels after setting the operation channels of the
microphones and receiver.
4. Also remember to check the volume settings on the mixer or amplifier the receiver is
connected to.
Setting the Tone:
1. You can set the Tone by using Tone adjustment knob.
2. The optimal setting is for the indicator to be set at the 12 o’clock position, half way
between the LO and HI settings.
3. If you need high treble, rotate the adjustment knob clockwise. If you want to reduce the
amount of treble, turn the adjustment knob counter-clockwise.
4. You should use the Tone setting to make adjustments if howling occurs.
*** If setting the Tone to the highest setting, howling is likely to occur.
Setting the Squelch:
Squelch is a method of eliminating channel noise that may occur when a microphone is not in
use. Squelch suppresses the output until a stronger input signal (voice, etc.) is received.
1. Using the RANGE/SQUELCH adjustment knobs on the back of the receiver, you may
adjust the settings for each channel individually.
2. If you find that the receiver is picking up distortion or undesired noises, set the
adjustment knob to HI.
3. In the case that interference occurs when you are trying to use a microphone, turn the
adjustment knob towards the LO setting.
SETTINGS

12
www.barosnt.com
Setting the Receiver Channel:
1. Adjust the HOLD switch so that it is in the UNLOCK position. In this position you may
adjust the channel setting.
2. Press the ↑button to increase the operating channel setting. Press and hold to cycle
through the channels quickly.
3. Press the ↓button to decrease the operating channel setting. Press and hold to cycle
through the channels quickly.
4. Once a channel is selected, move the HOLD switch back to the LOCK position so that
the operating channel cannot be changed.
*** The operating channel frequencies can be found on page 16.
*** In schools or other settings where multiple receivers and microphones are used in close
proximity to one another, different operating channels should be selected for each receiver.
This will help to prevent receivers picking up unwanted signals from other devices.
Setting the Hand Mic Channel:
1. Start by turning on the microphone. The status window will illuminate and you will be able
to view the current channel setting.
2. You will notice a small hole under the switch. The
button to adjust the channel is in this hole, and you
will need a 1~2mm diameter pin or tool to press it.
Pressing the button once will advance by one
channel. Pressing and holding the button will
advance continuously.
3. Note that there is only one button, pressing it will cycle upward through the operating
channel range. If you go over the desired channel, you will need to cycle through fully
until you reach channel 1 and start over.
4. Note the operating channel set on the receiver. You will need to match the microphone
to the channel setting on the receiver.
5. After setting the channel, turn the power switch off to save the selection. Turn the switch
on again and the selected operating channel should appear.

13

System Operation:
1. Ensure that all components are connected properly, and that the receiver output is
connected to your audio system’s mixer or amplifier.
2. On the rear of the receiver, turn the Power switch to the ON position.
3. Note the operating channel number appearing on the receiver and confirm it is correct.
4. Turn on the microphone and ensure that the operating channel matches that of the
receiver.
5. By turning ON/OFF the microphone’s power switch, you can confirm the operating
channel.
6. After viewing the channel on the hand mic for 3 seconds the status window will
show “- -”.
7. If there are any issues or abnormalities with the audio transmission, re-check the system
entirely.
8. If purchased with the optional microphone charger, always return the hand microphone
to the charger after use. Be sure that both the microphone and receiver are powered off
before placing the microphone in the charger.
OPERATION

Hand Mic Battery Replacement:
1. If the batteries are low, the status screen will flash a “LO” warning.
2. If using the rechargeable Hand Mic system, return the microphone to the charger. If the
batteries will not recharge, they are worn and should be replaced.
3. If using non-rechargeable batteries or if your rechargeable batteries need replacing, turn
the Mic Handle counter clockwise to remove it and access the Battery case.
4. Remove the 2 x AA 1.5V batteries and replace them with charged ones.
5. Be sure to install them following the +/- symbols denoted on the battery case.
6. Close the battery case and the microphone on. The operating channel setting should
remain unchanged.
*** Never place a microphone with non-rechargeable batteries installed into the charger.
