How to connect it ?


Instructions
    • 1

      Place your mixer in a location that will allow you to hear the sound coming from the speakers clearly. The best placement is opposite the speakers, centered between the left and right pair. Connect the power supply to your mixer.

    • 2

      Connect the female end of an XLR cable to a microphone. Run the other end of the cable to your mixing board. Plug the male end into the "Mic" port of an open channel. These channels provide the preamps that will shape the sound characteristics of the microphone signal, processing them for output. Repeat the process for each microphone in your rig


    • 3

      Connect one end of a balanced 1/4-inch cable to the left channel jack labeled "L" found on the "Main Out" panel. Connect another cable to the right channel jack with the "R" label. Connect the opposite end of each cable to the matching left and right inputs on you amplifier.

    • 4

      Power on your mixer and amplifier. Test each microphone connected to the mixer for output.

    • 5

      Adjust the volume of each microphone channel to create a balanced mix. Use the "EQ" knobs to shape the tone and cut out frequencies that are causing squeal and feedback.

Simple Tips for PA Systems for Conferences and Conventions


There are so many problems that could possibly happen when you go live with an event, I couldn't possibly list them all!
In fact, I keep finding new things that can go wrong every time I set up an event!
But all is not lost! In fact, it's just the nature of dealing with a lot of people and live event ---- anything could happen!
Let's look at some of the things that you should be prepared for, and what you can do about it!

Hiss

Hiss is usually caused by some device, usually an MP3 player or other kind of music player, that isn't turned up loud enough. Try turning it up.

Feedback and squeal

This the classic -- we've all heard it - and it can be a monster.---- you NEED to understand how to place speakers properly, how the system works in general, and how to set volumes.
Be absolutely certain that your speakers are not behind the microphone!

Howl and echo

Sometimes instead of a high pitched, full fledged feedback, you get a howling or echo sound that changes as things move around. When you touch the microphone it stops. Let go and it starts again. Move a little to the left and it's not so bad ... You can dance around all you want, but what you have is a problem. And this is a problem that can be impossible to fix once the event is underway. This is why we test before the audience arrives.
What causes the howling and echoing is the same thing that causes feedback - what you have is sort of "baby feedback" - it hasn't grown into full feedback yet. And it's correct for you to be concerned. Turn one thing up a tiny bit and the whole room will be overcome by a deafening squeal.
Two quick points - make certain that your speakers are placed forward of, NOT behind, your microphones. Moving them forward even just a few inches will make a very significant difference if they are already forward of the mics and you are getting howling or echo. Also, it's important to know where the volume control is, so you can turn it down fast if something goes wrong!

What about if the echo isn't the beginnings of feedback? Well, there's the possibility that the system may have some effects, like echo, that are built in. There might be a section called "effects" - and echo is selected and turned up. It's important that someone needs to understand the basic system and be in charge of it. That will solve this problem.

No Sound At All

First thing I would think is, it's a bad cable, probably a bad microphone cable. Especially if its a portable system. Be sure to take care of the microphone cables. In the industry we use the terms "known good." For example, I will always carry with me a cable that I know is good. If I need to troubleshoot, I swap the "known good" cable for one I suspect isn't working. Mic cables will just stop working sometimes. And then there's no time to fix it - you need a spare. Also, make sure to either dispose of the bad cable, or mark it - don't let it show up again in your setup!

The people in the back of the room can't hear!

This is actually a very common problem. When the speakers are properly positioned, you don't need to turn the volume up very high, and everyone will be able to hear very well. If you are running a conference or convention with 500 people or less, say, in a hotel ballroom, and using a portable system, try bringing one of the speakers back halfway into the room, and positioning it near a ceiling support beam so it's not too much in the way. If you have long enough speaker cables and can do this, your volume requirement will be far less to get nice clear sound to the people sitting in the back of the room!

General Tips

If you're setting up a portable system, keep the cabling safe and and as neat as possible. When something goes wrong it'll be easier to figure out, and make sure you tape the cables down so that people don't trip over them.

Use sturdy, well made speaker stands in portable systems

Keep audio cables and power cables away from each other

Never plug anything but a speaker into an amplifier output

Coach the presenters if you can - ask them to speak about 4" from the microphone

Never coil cables with your elbow - don't let them twist and they'll last a long time

Never coil extension cords (power cords) while they are being used, it creates an electrical field that can be dangerous and damage your equipment or even start a fire - don't use extension cords that are longer than they need to be.

Watch out for dimmers that control lights - turn them off if you have buzzing sounds

Always prepare - preparation is the best way to ensure a successful event.

This may seem like a lot of tips - you can review this list and find more related information at our website, whamuniversal.com

My samson microphone c01u works but i cant hear my mic thru my speakers it does not record out


That's normal. You're supposed to record a track and then play it back. In order to hear it live you would need to enable "software playthrough" in your recording software, but there will be a delay, so it probably won't be much use.

Microphonic tubes can be detected by tapping them lightly with a pencil. I cannot find if this uses a spring reverb, but if it does, vibrating the cabinet will get a clanky type sound from the reverb tank. This MAY use a digital reverb however which is immune to that. Next thing is to make sure your guitar can't "hear" the output sound of the amp because the strings can pick up the sound and resonate feeding back into the amp. You can detect if this is happening by quickly dampening the strings and see if ringing gooes away. You probably need 6 to 10 feet of clearance between the guitar and the amp OR put your body between the amp and the guitar. ALWAYS set sound level at safe levels. Get a sound meter and go no higher than 90 Db. I know a lot of near deaf musicians whose careers are near over because of hearing loss using too high level.

Assuming you are running windows XP you need to

1. right click the speaker in the lower right corner and select adjust audio properties.

2. Select the audio tab

3. Pull the drop down menu under sound recording and make sure it is selected to your audio driver device. Most are either soundmax, creative(for soundblaster and audigy standalone cards), realtek, or ASUS.

4. Next repeat step one but select open volume control

5. Go to options and then properties

6. Select the circle for recording and make sure your mic input is checked.

7. Close that window and recording mixers will pop up. Select the input you need by checking the box in the lower left corner of the mixer channel. Adjust the level and then use your recording program or sound recorder under Program files>accesories>communication>sound recorder.

The speaker connected to my Yamaha EMX 312 SC is not bringing out any sound when we use the microphones but the displays on the power mix shows there is activity.


Assuming that you have checked the speaker leads for broken connections and that you know the speakers themselves work okay (test with a different amp) and that you can hear sound on the headphone socket
  1. Check that you actually have the power amp switch in the right position for the outputs (monitor jacks or main neutrik/speakon sockets) that you are using (see page 25 of the manual)
  2. That your speakers are connected to the speaker outlets on the rear panel and not the 'main outputs' on the front panel, which are for use with a separate power amplifier
  3. Check the mute button is not in
  4. You have turned both the master volume controls up.
If none of the above solves the problem it is likely that the overload protection fuses on the amplifier output stage have blown and need replacing - take to a repairer

My power light is on but ther is no sound alteration from the talkbox i am using an alternet power supply could this have anything to do with this problum.


The pedal does NOT alter the sound... you probably don't understand how it works. Visit this YouTube site and observe:

http://www.youtube.com/watch?v=gkryZXYl0LU

Note that you have to have a microphone to pick up the sound. What the device does is to put your guitar sound into your mouth where you modify the resonance like when singing and then the modified sound is picked up by the microphone the hose is strapped to. I would suggest using a Shure SM57 micrcophone. Notes that your guitar sounds via the cable are NOT modified in any way, only amplified to put into the tiney speaker that drives the hose up to your mouth.

When we are trying to get a reasonable level of sound for vocals before it gets loud enough to be able to hear clearly with the band playing it starts to clip at the speakers now we are only using this set...


Proper level setting of the mixer is important. HOWEVER if the clipping is occuring at the speakers the only possible problem MIGHT be that you have a supersonic feedback that is saturating the speakers above your hearing range, Be sure you don't boost the highs too much with the EQ as this can cause the feedback that you can't hear. Also make sure that you power the speakers from the SAME receptacle as the mixer, even if it means running an extension cord to bring power to the mixer. This is to avoid a low frequency hum and common mode distortion/damage. A low frequency hum could cause the clipping.
It would be a good idea to get a sound meter to check the sound level. You should be able to reach 85 Db from this system without clipping. If you need more than that, you MAY need more speakers if the band instruments are too loud. Also if the band has amps that get into the vocal microphones that adds to the clipping level... make sure the mics don't "hear" the band instruments. Make sure your speakers are toward the audience from the mics to avoid the supersonic feedback problem. If the vocalists can't hear themselves with that configuration you need to set up seperate stage monitors.

There are some pretty good videos on YouTube about proper mixer level setup.
