How to connect Behringer qx1200 mixer with pc and pc/speaker? I tried all solutions but i didnt' get any sound. Earphones works great


the mixer connects to the pc via usb or analogue i/p's
the mixer does not connect to the pc speaker
this has to be done with the software you're running on your computer
the easiest way is..plug the headphone o/p into any amplifier line i/p
( amp and speakers or powered monitors ) and forget about the pc speaker ..they're sh!te period ..or you can plug the headphone
o/p into the mixer then the mixer into an amp but this is more complicated and you will need to read up on it
but do yourself a favour and get some small multimedia speakers
similar to these for starters http://www.ebay.co.uk/itm/GENIUS-BLACK-MULTIMEDIA-STEREO-SPEAKERS-SYSTEM-for-LAPTOP-DESKTOP-PC-COMPUTER-UK-/250929417549?pt=UK_Computing_Speakers&hash=item3a6c8f0d4d

You need a 3.5mm stereo jack to twin 1/4" jack plugs. That will get audio from your laptop to the mixer. Then, being Peavey, probably a pair or jack to jack 1/4" screened leads for signal from mixer to amp. Then loudspeaker leads to suit your amp and speakers.

Trying to install samson studiogt monitors but can't find driver


The speakers are electro-mechanical devices, not electronic devices.
So, no "device-drivers" are needed.
Just connect the speaker-leads to the "audio-out" from the computer,
and connect the AC power cord from the speakers to an AC outlet.

I plugged in my Altec AP3 Speakers to my computer running windows 7. It does not play. i get sound directly from my PC (it had sound prior to plugging in speakers) however the Altec speakers have no sound


Hello
You haven't specified from which computer source you connects this device with. If it is from the audio out socket of the PC, your PC's audio card [or onboard audio] dirive hasn't been installed yet. Unlike WinXP, Win-7 haven't all driver software in its driver cab when it is installed. If onboard sound should energize, the mother board CD should be loaded. There is audio and video drive [normally NVIDIA] drive should be installed. Anyway, you have to install the dirve. Now it disabled. Go to the hardware confujuration of your system, and look whether onboard audio is disabled. If it is disabled, inable it. If there is no driver installed to it, the system will ask CD. Then insert the CD into the CD tray, and follow the instructions. If your Win-7 is registered, you can get diretly into Microsoft site, and can download the driver needed. OK.

Speaker humming....what is the course?


How to Eliminate the Hum and Buzz from your Sound System

Is your sound system making noises you don't want to hear? Try these tips to clear it up!

Instructions


Hum is usually the result of using electrical outlets with different grounds. To verify this, run an extension cord from the outlet that the amplifiers are plugged in, to the mixer.

Remove all the DI boxes and adapters. Connect the mixer to the amplifiers with balanced cables.

Be sure that all your cables and connectors are correctly wired:

Pin 1 shield
Pin 2 + white/red
Pin 3 - black

Note: If the system has an electronic crossover, equalizer, or limiter....you need to keep them in the signal chain to protect the system from damage. Just make sure all the cables are balanced and the pin-out on the connectors is correct.

If your gear doesn't have balanced connections use good shielded cables with the proper connectors.... NO ADAPTORS!!!


If the system still has noise, check each channel on the mixer by removing the input connections. There may be a DI box on stage that is also interacting and causing a ground loop. If that is the case try a different DI and make sure that all the instruments and amps on stage are also on the same dedicated ground as the mixer and amplifiers.


If the hum is gone using the extension cord you will need the have your electrician run a dedicated ground to the mixer and amplifier electrical plugs.

Is static causing problems in your reel-to-reel (web) process?



Tips & Warnings

*
Removing the DI boxes, hum eliminators and bad cables may improve the sound quality...unless the DI boxes use very expensive line level transformers (Good ones are about $75 for just the raw transformer inside the box) the signal is being squished thru a $5 instrument level DI box.
*
DO NOT lift the grounds on any of the AC inputs to the amps or the mixer as this could result in electrocution. OUCH!


Hope it helped..

Please don't forget to rate me ..Thanks...

Have a nice day..

How do i go about connecting the alesis monitor one mk2's to my my laptop? i do not have an amp and there are no cables or connectors with the speakers when they arrive


You can without an amp in between. They are non-powered speakers and need an amp to drive them. If you connect your laptop to a mixer, mixer to an amp, then amp to speakers THEN they will work.

Installation of speakers


The speakers require the AC adapter to be connected for the speakers to function. The AC adapter powers the amplifier of the speakers

E6500 making a beeping noise


Does beeping noise happened before turning on laptop? If yes unplug the laptop from the AC Adapter. Just leave AC Adapter ON and connected to the power outlet. Check if AC Adapter is the one making beeping noise. Note: This is an issue with dell AC Adapter laptops
If no beeping noise in AC Adapter then proceed checking it from the laptop. Does beeping noise happened immediately when laptop is turned on? If yes then it might be laptop's hard drive creating the sound. Try to check the BIOS in your laptop under the category performance if the HDD Acoustic is ON either in Normal or Performance. Note: When laptop is in performance the hard drive makes noise due to its speed, this is normal if BIOS HDD Acoustic mode is ON to performance.
If the noise only happens when sometime while working on the laptop, this might be cause by the laptop fan. This also happens after turning on the laptop fan my have dirt and dust, please do check.
If fan was cleaned, HDD performance was checked and AC adapter was checked then, carefully sense if noise is coming from the internal speakers.
Download the latest BIOS update for your laptop then flash the BIOS. Make sure battery and AC adapter are connected when doing these.
