Question 1

What could be causing a strange static sounding noise in the headphones only when pressing PFL on any channel.

The "PFL" Stands fo r"Pre Fader Level". Just in case you did not realize. so when you press the "PFL" button , and the red light goes out?, You're saying that the hissing goes away and that you have clarity. Yes? and the volume presents no issues? Also correct? Part of that simply, is with the PFL in the on position. You are engaging the fader for one, which will add to an already boosted signal ( the the fader is turned Up?). also you may have your Clip set incorrectly. to set this you turn PFL off, then at your signal input level Dial (usually at the very top in-line with your fader. _ set the volume on your device, then input clip level on the board \ to where the clip light comes on. not a steady light, but a blinking light so make it steady, then back it off a hair. Okay? this whole time make sure your mains are down. or off at the faders. Once clip is set., PFL is in off position, gradually turn your mains up to level. Now, the PFL is for when you have more than one signal. say from an instrument on another channel. unless you have that? No need to use the PFL. If you do have an instrument in line,. then, before you turn PFL on,make sure that your fader on that channel is turned off. -turn on your PFL, then gradually bring that to level. never messing with the mains level.

I know that is a lot of info. but it is a process. that should eliminate any hissing you may have heard.
Good luck!!

When setting up xr8600 is it best to start mains and monitors master at 0DB?

1. Turn the main and monitor volumes all the way down (off). Plug a cd player into channel 9/10 and play a track of music of your liking. With the main/monitor volumes still off, adjust the gain on 9/10 until the clip light turns on, then back it down until the clip light just turns off. Put the channel volume at 12 o' clock.
2. With the music still playing, turn up the mains to the desired listening level first, and then adjust the graphic eq until the music sounds good in the room. Remember or mark the position of the volume control. Do not use the channel eq on 9/10 for music that has been mastered properly, leave the eq flat. Once this step is completed then you have now set the main eq.
3. Repeat the same for monitors. Turn off the main volume and then bring up the monitor main volume to the desired level first, then set eq. Now your monitor eq is set properly. Remember or mark the position of the monitor volume.
4. Set up microphone - plug a mic into channel 1 with volume all the way down. Speak or sing into the microphone and adjust the GAIN until you see the clip light, then back down a litttle on the gain. Put the monitor and main volumes back up to the mark from step 2. Now adjust the volume and monitor send on the mic channel to the desired loudness first before adjusting the mic channel eq. Use subtractive eq method to minimize distortion and feedback. ...i.e. if the mic is bassy then turn down the lows, do not ADD highs. If the mic needs bass, turn down the highs.

No sound coming out of my mackie

Whether you are experienced in electronics repair?
if not, try this simply way:
1: Test whether the power amplifier is still working. See figure 1.
Power OFF,adjust the EQ settings as shown in the picture.
Minimize LEVEL.Switch ON Power. Touch pin 3 at the INPUT socket by using a small screwdriver or piece of wire / cable.
Slowly raise the LEVEL,a little bit only (as the clock showed 7-8) until
sound is heard in speaker. If not heard, slowly raise again LEVEL.
If audio input signal is heard,it can simply be taken to mean
that the amplifier is working.
If LEVEL at 9 o'clock position,and the audio is not heard,
the possibility of the amplifier is damaged.
Switch OFF the power. Take it to a repair place.

2: When the Power LED is lit, but no sound,
There are many possible causes, one of which is:
I have been getting 3 times similar cases, and all are caused by
two Rectifier-Diode (either or both.) damage on the power-supply-unit.
Remove/desolder,measure, if damaged replace it with a new one.
See figure 2-3.

Hope it helps. Regards.

Mpc 1000 loud static

Maybe try adjusting the MASTER level?

Good Luck

Other settings
Adjusting the master level You can adjust the level of the headphone and the stereo out by turning the MAIN VOLUME knob. The MAIN
VOLUME changes the analog signal level. This will also adjust the entire level of the MPC1000 digitally.
01. Press the [MODE] key and then the [PAD 10] (OTHER).
It switches to the OTHER mode.
02. Press the [F1] (GLOBAL) key.
The GLOBAL page will be displayed.
03. In the Master level field, set the level.
You will set the digital signal level, which will be sent out to the DA converter. The MPC1000 can output up to
32 sounds simultaneously. There is the great difference in the level when you play single sample and play 32
sounds. If you increase the value in the Mater level field, you can increase the entire level of the MPC1000 to
create more powerful sound with less noise. However, if you playback many sounds at the same time, the
level may be overloaded, which may cause distortion. If you decrease the value in the Master level field, you
can prevent distortion when you play many sounds at the same time. However, you cannot have a good
result in respect to the noise or punch of the sound. Set the appropriate value in the Master level field
depending on the application.

Clipping always lit

Make sure nothing is plugged in.
Turn the GAIN, LEVEL, and FX knobs for each channel, counter-clockwise all the way.
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...

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

I bought my g-dec jr form ebay last summer and really like this little amp but this past winter I went to use it, it worked for 3 to 5 min and shut down, but the power light just blinked moderately. I...

This amp uses a TDA2050 chip that has thermal protection. It is also a small amp that is NOT capable of high sound levels. If *********** can't stand to be within 5 feet of this amp you are playing TOO LOUD for this amp and it will shut down until cooled off to protect the amplifier chip. This amp is intended for practice. It would be adequate for sensible listening level in a 10 foot by 10 foot room. If you need more sound you will have to get a bigger amp. I would suggest you get a sound meter and verify the sound level. DO NOT exceed 4 hours at 90 DB... I know a lot of deaf musicians that have lost their hearing and they are not much good anymore.

Hi, I'm dealing with a problem on my Mackie ProFX 8 mixer. For no reason that I can discern, I am simply not getting any signal out of the mixer. I've adjusted the appropriate levels and gains,...

Are you getting signal into the mixer? Do the level meters light up?

If so, check your speaker cables. If not, check the mic cables and mics (try with phantom power on and off).

Also, try plugging a speaker into an Aux out to see if you can get level out of that.

Hope that helps...

HOW DO YOU TURN DOWN THE HISSING NOISE

You can cut the treble gain some BUT most importantly is to send adequate signal to this speaker so volume level does not have to be set high when sending LINE LEVEL signals to it. Hissing noise is a product of the statistical noise that occurs in electronics. Running any device at high gain invariably brings up the hiss level. Managing thee signal levels is the responsibility of the sound engineer.

ALSO feed ALL interconnected equipment from the same receptacle or power source, even if it means running a power cable to a mixer alongside the snake. ALWAYS USE BALANCED audio cables whenever possible.

Make sure ALL interconnected equipment is powered by the same receptacle or power conditioner. Do NOT use separate recptacles at opposite ends of a romm for example. Run power extension back with your snake. There may be a failure in the unit. Since it is so new, exercise your warranty... do NOT risk voiding the warranty. Do verify that your power is clean.
