Hi i need to connect a microphone to the mixer and output sound to a tv monitor to hear audio across a cctv camera. hope you can help. adrian

Generally mono outputs on this kind of mixer are usually balanced. This means all three poles of the connector are connected. The hot or plus signal (tip) will go to the left of your phones, the cold or minus (ring) will go to the right. This will be ok from a sound point of view But it may not have enough drive to make the phones loud enough.
If you only hear a signal in the left then the output is unbalanced.
A simple fix is a cheap headphone amp (less than 20 pounds) and a simple jack to two phono lead (wired as a split). There is a ton of old audio equipment about for very little money including some very small mixers, that have headphone outputs, that is what I have done a lot in the past.

Skype allows only one audio input at the time. You can set up the input device in the skype menu.
Try connecting all microphones to the Mackie and then connect the output from it to the line in or microphone input on the PC, then choose the input you connected it to in skype.

This is not a powered mixer and so you must connect a power amp to the "line level" outputs of the mixer. Other "no output" problems could be related to buss assignments and other signal routing issues. Check for output by connecting "Main Out" left or right to a guitar amp input instead BUT turn all volumes down to zero before conductiong this test as guitar amps are designed for "Microphone" level inputs. Owners and Hookup manuals can be found here...

Instructions

1. • 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

     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.

Depending on what other settings are chosen- this at times can be normal. You may be simply switching from the output of the mixer board to the sound input source, and if gain is up and mixer level is up, you will hear it. If it is outputing to the host and it should not be; check stored settings and Scene memory.

hi,
this mixer has output's from cd/tape(rca plug) that can be used to connect an additional amp for output to a sub. It is designed to use for recording but may also server as a pre-amp output to an external amp of choice.

there is a main output, conect it to the aux in line or to the microphone line.good musics

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

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.

This particular mixer offers a usb (2 channel connection) that can be simply plugged into the computer usb 2.0. These channels should be available in Sonar from the channel Input/output drop boxes. You may need to restart Sonar, the mixer or both for them to be recognized. You may also need to run the Wav Profiler in Sonar. Typically the Wave Profiler is found in the Options>Audio menu but may be different on each edition of Sonar. The above info is for Sonar 7.

If you are wanting to record several channels at once then I would recommend connecting your Mixer's Direct Outputs from each channel to a corresponding input of the soundblaster if your soundblaster supports multiple channels. And then use the usb outbut from the Sonar to monitor the computer playback of your master stereo channel. Or, you may connect the soundblaster outputs to unused channels of the mixer or to the tape return or auxilary inputs to monitor the computer playback on the mixer.

Alternately you can send the signal to your soundblaster via the buss outputs. This will limit the number of simaltanious output channels to the number of busses on the mixer, but you can send any mixer channel to any buss without unplugging the instruments or mics.

Here's the link to the page where you can download the free pdf manual for this mixer. Page 14 explains the output connections and has diagrams.
