Receiver does not seem to work anymore...

Hello all, I have the receiver plug in my system. It used to light up when it was plugged and the receiver and mic were put to On. Now, I can't get anything... I know the mic works cause I replaced the wireless signal sender with an xlr cable and everything is working... Any suggestions ?

Thanks, so much and I already kind of tried that. What I mean is that... it does not have the standard output RCA cable, instead it only has a one prong cord (it is a larger, headphone (like) cable with one big prong on each end). I tried to plug it into the headphone (output) on the JVC which of course didn't work. This is the only place to plug directly into the stereo JVC receiver. So I went to Radio Shack (they are so not techie), they talked me into a stereo to mono converter. It converts from the one big prong to the 2 red/white RCA prongs. I plugged the one prong end to the Trident Mic receiver, then took an RCA cable and plugged that into the other end of the converter then into the DBS port on the JVC receiver, turned everything on and ta da nothing. However, I wondered about the color scheme and the Radio Shack guy said it didn't matter. I will go home and check the connection. I was pretty sure that I had to do something with the mode (your analog/digital comment). I will go home and check that, too.

Thanks for posting. It sure seems like it should work pretty easy, but so far no go.

I will post back, in the meantime, if you have anymore suggestions, please be sure to post.

Ciao and Much Appreciation,

How do you hook up asamson concert 77 wireless system to speakers


No that doesn't work because the headphone jack on your receiver is a output. You need a input like the AUX, so you need a adaptor from jack to cinch.

When, I am walking around with either a guitar plugged in or a lavaliere microphone. I continue to get pops and static surging sounds. Is there a way to fix this.

Although it has 2 antennae the AT201 is a single channel transmitter and receiver. As you move the transmitter about in relation to the receiver you are finding 'dead spots' in the room where the signal is reduced or even drops out completely. You can reduce the impact of this somewhat by doing the following things.
  1. Make sure there is a clear line of sight between transmitter and receiver.
  2. Move transmitter and receiver closer together
  3. Do not locate the receiver near large pieces of metal or near other electrical equipment, particularly things that have strong magnetic fields like transformers (including amplifier power-supplies) CD or DVD players, hearing loop amplifiers and loop cables.
  4. Turn off mobile phones and any other radio operated equipment that is not needed
  5. Turn the trim control on the transmitter to the maximum output that you can without causing distortion. The stronger the original signal from the transmitter the lower the related noise will appear to be (called signal - noise ratio)
  6. Turn the squelch control on the receiver up a bit to suppress noise - however doing so will reduce the strength of the output signal a bit so don't over do it.
  7. Use good quality screened cable between the receiver and your amplifier. Unfortunately the AT201 only has an un-balanced mono jack socket so this cable will be more prone to pick up radio interference than a twin core plus screen (balanced) cable.
  8. Make sure that your signal cable does not run parallel to, and close to, any mains electricity cables. If the signal cable needs to cross any mains cables it should do so at 90 degrees and the cables router well away from each other.
However the only real solution to this sort of problem is to use a full duplex (2 channel) transmitter / receiver system which will automatically switch to whichever channel is carrying the stronger signal. Typically these cost about 70% more than single channel units but they often use balanced cable outputs (stereo jack or xlr) which further reduce the propensity for noise due to interference.

My Samson Wireless Lapel mic system has stopped working. First the reception became intermittent... a few days later stopped working altogether. I was hoping that it was just a bad set of...

There could be a number of reasons for this problem you will need to work through them from one end of the system to the other to diagnose.
Start with a bit you know is working.
  1. Look at the receiver unit first. Do the indicator lights come on when you switch the microphone on? If yes hold the microphone belt pack about a couple of feet from the receiver and move it from one side to the other. Do the lights flicker? If it is a 2 channel (dual diversity) model -do the A and B channel lights flash on and off to indicate that the receiver is switching channels? If they do the problem is unlikely to be the microphone or belt pack.
  2. Is your amplifier/ computer/ audio system producing sound from other sources (e.g. radio etc)?
  3. Unplug the output lead from the back of the receiver and plug a cabled microphone or other sound source / instrument to it to test the cable.
  4. It may be some sort of external interference. Most of these sort of microphones can be switched to different frequencies. Try changing frequency (usually a little rotary switch on the back of the receiver and inside the battery pack - will often need a small flat bladed screwdriver to operate it) and make sure that there is a clear line of sight between receiver and transmitter units with no large lumps of metal or electrical devices in between.
  5. Do not use re-chargeable batteries as they almost never achieve an adequate voltage. Always use Duracell Ultra or equivalent.
  6. The capsules and cables of lavalier / lapel microphones are very prone to failure. Try removing the microphone jack lead and plugging in a different one . If you don't have another microphone try a simple audio lead - maybe a mini jack-plug to standard 6mm jack and connect an electric guitar or other sound source (or just touch the bare plug contacts at the other end of the lead to see if it creates a sound) . Does it work? If it does then it is possibly the microphone itself rather than the belt pack. These microphone capsules are not repairable and mending the cables / jack plugs can prove very fiddly, (lost are moulded units and cannot be dismantled anyway) however replacement microphone capsules are not very expensive (about £16-£20 in the UK) but before you replace it see steps 7, 10 and 11 below because it could just be a problem with the jack socket on the belt-pack
  7. Look at the jack socket itself. These often attach to the case of the belt-pack with a threaded ring that screws onto the socket unit. Sometimes the screw ring can work ever so slightly loose - which means that the jack plug doesn't quite go far enough into the socket to make a proper electrical contact (we had exactly this problem with a different brand of lapel microphone).
  8. If the tests at no 6 don't find the problem examine the wire aerial on the belt pack carefully. Sometimes the central core of the aerial can get cracked by frequent bending (usually when people stuff the belt pack in their pocket). Try twisting the wire backwards and forwards gently. Work all the way along it's length - does this make the unit work -albeit intermittently?
  9. Dismantle the belt pack to check that the aerial wire has not got broken off the circuit board.
  10. While you are in there check that the wires to the microphone jack socket have not got broken off or stretched so that the screen and core are shorting out.
  11. Put a battery in the belt-pack and try touching the contacts on the microphone input jack socket with a small screwdriver or other metal object - does this produce any sounds? If so it may be that the contacts inside the socket are bent and therefore not touching the pin of the jack-plug. Some careful re-bending with a thin probe may solve the problem.
  12. If you have got this far you can be fairly certain the fault like in the microphone capsule because you have eliminated every other possibility

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).

This is not syncing with my pgx4 receiver The batteries are fresh. The receiver is plugged in The channel automatically selected. The green ready light didn't turn on, on the receiver, but the microphone...

Look for a possible source of interference.

The unit is likely FM and an FM receiver will "capture" the strongest signal right one or not.

Key is to find which of the two components is faulty. The green LED's really mean very little... other than battery and carrier received.

If you can find another system to isolate which is failed, then progress can be made.

Handheld transmitter doesn't work


I don't know which type of microphone you are using.
You can check on the receiver if the RFsignal is present, some receivers do have a led-bar for it.
If the RF signal is there, you can check the microphone element. I'm sure you're microphone insn't in the mute function. Unscrew the microphonehead (if possible), look to the wiring, there must be 2 wires. If you touch one of those wires, you must get a hum out of your system.
If not, your transmitter has a problem and you have to visit a repairshop.

Good luck,

Sennheiser em100 g2 receiver passes major static to mixer

This is a well known problem with the EW100 series that is easily solved.
You will need to run this reciever into a line input via a mono(TS) jack to jack lead. this will bypass the phantom power.
Make sure that you set the AV OUT to +18 in the reciever menu to get optimum level.
Phantom power is only present in the microphone inputs XLR3.
Hope this helps.

Set-up wireless karaoke Mic.

I can't seem to find any technical details on the output specifications of the karaoke mic, but IF it outputs in consumer standard RCA format (a cable with two ends, one red and one white - often seen with a third yellow cable for video), then you should be able to plug it into the back of the receiver without trouble. Simply choose one of the audio connectors in the back to function as your microphone playback system - I suggest the DBS connector, unless you have a satellite system already plugged in.

Connect the Red RCA cable to the RIGHT channel port on your receiver and the White RCA cable to the LEFT channel (Red = Right). Now, select the DBS (or whatever port you plugged it into) using your receiver remote control. Hit the "ANALOG/DIGITAL" button on the remote until "ANALOG" mode is displayed.

If you want to connect the mics to a Karaoke system using the same receiver, simply unplug the White RCA cable from the Microphones, and plug in the White RCA cable from your karaoke device. Now, you'll get music playing from one side of the speakers, and mic playback from the other side, simulating the karaoke experience.

NOTE: If the microphones do not have a RCA plug on the back, please post a picture of the reverse of the Microphone receiver, and I will see what I can do to help you further.
