Why don't i have any output both mic and transmitter are on ?


In a typical configuration you will need to connect the receiver to another device such as a mixer console. The mixer is connected to an amplifier. And lastly, the amplifier is connected to speakers.

Without more information, such as existing equipment in the configuration, I am limited to how much I can help you.

What are you trying to acheive (band, karioke, voice reinforcement, etc.)

What environment are you doing it in?

What equipment do you have besides the mic and receiver?

We bought a sound system and did not get instructions on how to set it up so we need to know how to plug in our yamaha c112v speakers adn yamaha monitors to our yamaha mg24 mixer please help!!!!


If all you have is monitors, speakers and the mixer, you are missing a vital component as you have no amplifiers.
You'll need at the very least one amplifier for the c112v's and another one for the monitors (chances are your monitors aren't 350W, so you don't want to drive them off the main amp, plus you need them controlled separately from the mixer). If you are intending to run sub-woofers as well, you will need an even beefier amplifier than the main amp for those.
You didn't mention the handling capacity of the monitors, but I recommend about a 300W per channel amp with 350W speakers - that way if you run the amp into clipping, it won't shred your speakers.

Mic receives a lot of static and then cuts out. After a few seconds it seems to repeat.


This could be due to interference from other devices.
You could try changing to a different frequency (there are 20 to choose from).
Also move the receiver away from any strong electro magnetic fields (hearing loop amplifiers, CD/DVD players, TVs) or large pieces of metal and in clear line of sight of the transmitter pack.
Set up the aerials so that they are at a similar angle as the aerial on the transmitter.
Only use xlr balanced cables with good quality screening to connect the receiver to the mixer / amplifier. Keep signal cables well away form mains electricity cables as far as possible.
Wherever possible use balanced xlr cables on all other equipment.

Have a Shure SLX Wireless System. The only way the microphone SLX1 or SLX2 is if they are right up to your mouth. If you put the lapel mic on a persons tie you can't hear them. The transmitter is set to...


The Shure SLX2 hand-held microphone has similar performance characteristics to the much-loved (cabled) Shure SM58 vocal microphone. It has a 'cardoid pick-up pattern' intended for close work - being spoken / sung straight into the top of the capsule at no more than about 8 inches from the mouth of the user- to minimise feedback and extraneous noise. If you double the distance between the mouth and microphone the sound level will drop four-fold so distance really matters.
The SLX1 lapel/ lavalier is a semi 'omni-directiona'l pick up pattern microphone, which should work satisfactorily up to 12 inches from the speakers mouth, but closer is better. Always try to get your users to hang it about 6 inches below their chin, at most, and preferably with the top of the microphone capsule pointed upwards towards the mouth.
Here are a few other things for you to try:
  1. There is a volume (gain) knob on the back panel of the SLX receiver unit. Try turning this up to maximum (needs a small screwdriver)
  2. Make sure that both aerials on the receiver are fully extended at different angles to each other and in a clear 'line-of'sight' with the transmitter pack, with no large bits of metal in between which could block the signal. Ideally the receiver should not be more than 25metres from the transmitter. If distance is a problem locate the receiver near to the transmitter and run a balanced (xlr) cable to your mixer/ amplifier.
  3. The angle that the receiver aerials are at should be broadly similar to the angle that the transmitter antenna is at to optimise signal reception.
  4. Make sure the receiver is not located too close to other electrical equipment which may be interfering with the signal (especially voltage transformers, CD or DVD players and hearing loop induction amplifiers which have a strong magnetic field)
  5. Always use good quality batteries - Duracell Ultra or equivalent ( do not use rechargeable batteries as they seldom achieve optimum voltage)
  6. Check that the antenna is tightly screwed into the SLX1 transmitter pack and not damaged.
  7. The SLX2 hand-held microphone has an adjustable level switch inside the body - unscrew the top of the microphone to access it - switch to maximum.
  8. Another possible cause could be an impedance mis-match between the SLX receiver and your amplifier or mixer. There are two outputs on the rear panel of the receiver. One is an XLR (large 3 pin socket) this is LOW impedance and needs connecting to a low impedance input on your mixer/amplifier. You should normally be using this output even if your amplifier has a jack-socket input (use a proper balanced XLR to 6mm trs jack cable rather than a adapter plug). The other output on the receiver unit is a 6mm HIGH impedance, unbalanced, standard jack socket (labelled 'line in'). This would normally be to connect to a guitar amplifier which has a high impedance 'line level' input socket. If you are using this output you may need to use a pre-amplifier to get a big enough signal for a microphone.

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
to "Off."

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
your mouth.

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).

I bought a mixer with this model "Behringer XENYX 1204USB 12 Ch USB Mixer". And i'm planning to have a set-up of 2 electric-acoustic guitars and 3 microphone vocals. What would be the best wattage of...


Hello Sir, Hi, the amplifier best suited for it would be a Behringer also, the EP2500 would be a match, and the eurolive B815neo speakers, but this cost a lot, any amplifier and a corresponding speaker will do. for your electric guitars or acoustics the GTX30. If you will use your 15" speakers, match it with a right amplifier, you did not mention its watts rating, If your speakers are 250 watts, then buy an amplifier slightly higher that 250 watt,
