Microphone not working
hello there, Many steps to do
1. For your AirLine system to work correctly, both the receiver and transmitter must be set to the same channel. and check to make sure that the supplied receiver and transmitter are set to the same channel.
2. Physically place the receiver where it will be used (the general rule of thumb is to maintain "line of sight" between the receiver and transmitter
so that the person using or wearing the transmitter can see the receiver). The CR77 can be rack-mounted if desired (taking a half-rack
space), using an optional Samson adapter kit. The UM1 can be mounted to a video camera using the supplied velcro.
3. Extend the receiver antenna(s) and place it (them) in a vertical position. Make sure the Power on-off switch in your AH1 transmitter is set
4. Gently pry off the battery cover off the AH1 transmitter and slide it upwards and off to open the battery compartment. Please use care
when opening this cover as undue force will destroy the hinge.
5. Place a fresh AAA alkaline battery in the transmitter battery compartment, taking care to observe the polarity markings. Then replace the
battery cover and gently press down on it until it clicks. Leave the AH1 off for the moment.
6. Make the physical cable connection between the receiver output jack and a mic level audio input of your amplifier or mixer. The balanced
XLR jack is preferable, since it will deliver an electromagnetically cleaner signal. If required, both the balanced and unbalanced outputs
can be used simultaneously. If your system contains a CR77 or UM1 receiver, be sure to set its Audio Output Level switch correctly (see
pages 7 and 9 for details). Leave your amplifier (and/or mixer) off at this time.
7. Turn the Volume, Level or AF Level knob on the receiver completely counterclockwise. Connect the supplied AC adapter to the CR77
receiver and plug it in (the UM1 receiver can also operate off battery power or a 12 volt power supply from a connected video camera), then
plug the adapter into any standard AC outlet. Slide the Power switch in the direction of the arrow to turn on the receiver. If your system
contains a CR77 receiver, its "Power" LED will light steadily red. (Note: The UM1 receiver has no "Power" LED indicator.)
8. Turn on the power to your AH1 transmitter (using its Power on-off switch); the "Power/Battery" LED will flash if the battery is sufficiently
strong (if it lights steadily, the battery has less than 2 hours of power remaining and should be replaced). If your system contains either a
CR77 or UM1 receiver, one of the "A/B Receiver" LEDs will light, showing you whether the (left) "A" or (right) "B" receiver is currently being
used. The CR77 / UM1 meter will also indicate the strength of the incoming RF signal.
9. Now it's time to set the audio levels. Turn on your connected amplifier and/or mixer but keep its volume all the way down. Make sure
that the AH1 transmitter is unmuted (its Mute switch should be positioned away from the arrrow). Then set the Volume, Level or AF Level
knob on the receiver fully clockwise; this is unity gain.
10. Speak or sing into your headset mic (or play the instrument to which the horn mic is attached) at a normal performance level while
slowly raising the volume of your amplifier and/or mixer until the desired level is reached. The UM1 receiver allows you to monitor the
transmission signal using standard Walkman-type 30 ohm headphones connected to its headphone jack.
11. If you hear distortion at the desired volume level, first check to see whether the "Peak" LED on the receiver is lit . If it is not lit, make sure
that the gain structure of your audio system is correctly set (consult the owners manual of your mixer and/or amplifier for details). If the
"Peak" LED is lit, simply move the microphone further from your mouth.
12. Conversely, if you hear a weak, noisy signal at the desired volume level, again make sure that the gain structure of your audio system
is correctly set (consult the owners manual of your mixer and/or amplifier for details) and that the Volume, Level or AF Level control of the
receiver is fully clockwise. If it is and the signal coming from the receiver is still weak and/or noisy, simply position the microphone closer to
13. Temporarily turn down the level of your mixer/amplifier system and turn off the power to your transmitter, leaving the receiver on. Then
restore the previously set level of your mixer/amplifier. With the transmitter off, the receiver output should be totally silent-if it is, skip
ahead to the next step. If it isn't (that is, if you hear some noise), you may need to adjust the receiver Squelch control. When the Squelch
control is at its minimum setting, the AirLine system always provides maximum range without dropout; however, depending upon the particular
environment your system is used in, you may need to reduce that range somewhat in order to eliminate band noise when the AH1transmitter is turned off. To do so, use the provided screwdriver to rotate the Squelch control completely counterclockwise (to the "Min"
position), then slowly turn it clockwise until the noise disappears. If no noise is present at any position, leave it at its fully counterclockwise
"Min" position (so as to have the greatest overall range available).
