Output fader ineffective

The output fader on one of my HHBs is inoperative. It shows output level signal regardless of where the knob is turned. Input gain works.

It sounds as though the ground connection to the fader control has gone missing. Check with a meter.

How do I connect a Yamaha MW12CX mixer to a Yamaha Stagepas 500?

  1. Connect the output of the Yamaha MW12CX mixer to the input of the Stagepas 500 using a standard 1/4" instrument cable or an XLR cable. Connect the output of the mixer to the "LINE IN" or "MIC/LINE IN" jacks of the Stagepas 500, depending on what type of output signal you're sending from the mixer.
  2. Set the levels on the mixer and the Stagepas 500. Turn down the master volume on the Stagepas 500 and set the individual channel levels to zero. On the Yamaha MW12CX mixer, set the faders for channels 1 and 2 to the unity gain position (usually around 0 dB).
  3. Set the input mode on the Stagepas 500 to "LINE" or "MIC/LINE" for channels 1 and 2. This will ensure that the Stagepas 500 is receiving the correct input signal.
  4. Adjust the levels on the mixer and the Stagepas 500. Slowly turn up the volume on the Stagepas 500 while monitoring the levels on the mixer. Make sure the levels are not too high and that there is no clipping or distortion.
  5. Once you have the levels set correctly, you should be able to hear the sound coming through the Stagepas 500. Adjust the EQ and other settings on the Yamaha MW12CX mixer as needed to get the sound you want.
Note: The Yamaha Stagepas 500 has two more channels available, channels 3 and 4, which can also be used for additional inputs from the Yamaha MW12CX mixer or other sources.

What does manufacturer control auxiliary input auxiliary output mean

set level of input and output for audio .. similar to line in and line out of a stereo amplifier. This means you cannot alter the level of the signal out put or input to your audio system. It is set by the manufacturer. For a 1996 Ciera I assume you are adding some type of interface so you can either input or output a signal for a device. It is probably a set level on the interface. Some interfaces have tiny knobs where you can control the gain for input or output orthers are set by the manufacturer of the interface.

Clipping always lit

  1. Make sure nothing is plugged in.
  2. Turn the GAIN, LEVEL, and FX knobs for each channel, counter-clockwise all the way.
  3. Bring the MAIN fader all the way down.
If the signal LED's above the MAIN fader are still lit, then the board most likely has a short in it and will require repair.

If the signal LED's are dark, repeat the following on each channel...

  1. Rotate GAIN clockwise until the mark on the knob is at "12 oclock".
  2. Rotate LEVEL clockwise until the mark on the knob is at "3 oclock"
  3. Raise the MAIN fader to "0".
  4. Check LED's - if they light up then the channel you are working on is "noisy" or has a short in it.
  5. Return GAIN, LEVEL, and MAIN to "all off".
  6. Repeat with next channel.

Hooking up the speaker to an amp, using the rca line out of the amp i have no volume control from the amp knobs, can i hook the speakers up to the amp from the speaker out ?

You should NOT under any circumstances connect an audio input lead to a speaker output jack!
The RCA jacks you are trying to take output from ore "pre fader" which would be solid "line level" and not controlled by volume controls. Tap off the INPUT to the amp... you should be using balanced lines for the interconnects. RCA jacks are unbalanced lines. You can drive several inputs from a line level output of a mixer for example using a splitter cable.

I have a Behringer PMP 6000 that I just bought. With the power amp switch in Main L/Main R it works fine, but if I switch it to Main/Mon, only the Mon works, nothing from the Main. Bridge mode doesn't...

Bridge mode you use chan B (left connector on the back) using a SPECIALLY wired Speakon. The impedance of a speaker connected as such CANNOT be LESS than 8 ohms.

In the Main/Mon mode, the two amplifiers are separated in function. The monitor knobs for EACH channel input control the mix sent to Channel A which is for the monitor speakers. The Mon1 controls the level sent to Output A for the monitor speakers. Mon2 fader is NOT used.

The individual channel faders control the main mix and the Main fader controls the level sent to Output B which goes to the main speakers.

No sound

There can be any number of reasons for this problem - solve it diagnostically by starting with something that you know is working and work through systematically to the other end.
  1. Test a microphone on a separate amp to make sure it works okay. Check amp and speakers working. Check that all output cables from mixer to amp are working by testing separately.
  2. Plug microphone into a channel on mixer. Also plug in headphones and turn headphone volume control up.
  3. Make sure input sensitivity knob is turned up a bit (say half way) and main output faders (yellow) are up.
  4. Check that channel is turned on (little button just above the channel fader- needs to be pressed down)
  5. press pfl (pre-fade listen) button (next to button to switch channel on)- do you get any sound on main output or headphones or any indicator lights on mixer to show signal is getting that far (eitehr the individual channel metering lights or the main ones in the central section)?
  6. turn off pfl - make sure channel fader (slider) is up - normal position is ) - about 3/4 of way up. Check lights again on individual channel and main output section - any signs?
  7. Is the sub mix button for the channel pressed down - in which case you will need to bring sub mix (red) output faders up as well as main faders.
  8. If you have got signs of signal on the individual channel but not main see if the channel has been routed somewhere odd (like a subgroup of channels).
  9. Plug a working amp and speakers into one of the auxiliary outputs and use the relevant auxiliary send knob (on each channel just above the faders and pfl switches) to pan some signal to that auxiliary out - do you get anything? There is also a headphone socket for listening to the auxiliary channels (with a selector switch /knob to determine which one - make sure it is in the right position) try listening to the auxiliary output with headphones - anything? If yes the problem lies in the main output section.
  10. Check that there is not a jack plug in the insert socket (to route signal through an external effects unit) without a matching return jack being plugged in - if appropriate is relevant effects unit switched on and correctly set up - if unsure remove the insert plug to take it out of the system.
  11. Make sure any mute buttons are not switched in on main outputs.

How do I attach power amp to 1832 mixer

There are a number of configurations for a mixer like the 1832, the most common are PA system and Recording system. There are Main output jacks which carry the mix as summed in the main faders. These in a PA system would feed the pa amplifiers which drive the house speaker system for the audience. These connectors are XLR 3 pin type on the rear, intended for professional pa amplifiers which use balanced +4dbv line input level. Amplifier which have 3 pin XLR connectors for input signals can accept that high level signal. For home style HiFi amplifiers, the signal level is nominally -10DBv and balanced or unbalanced signal lines with 1/4in diameter phone plugs which are connected to the mixer by way of a second set of Main output connectors which are 1/4in phone jacks. Use whichever amplifier input level your amp has.
If you are not using it as a main PA house mixer, but using it for recording, the main output connectors go to a 2 channel recorder or computer sound card recorder. The power amp and your monitor speakers are connected to the connectors labeled "Control Room" (CTRL Rm). These output are useful for recording because the signal through the mixer can be monitored from several buses, Solo, main mix, selected by buttons provided. The buttons only affect the signal heard through the control room monitors, and not the main output which only sees the main mix so selecting "solo" does not interrupt the signal going to the recorder while the engineer in the control can be checking other signal paths through the board.
