If your amp states that it will support a range of 6 - 16 ohms, an 8 Ohm speaker will work fine on it. If the speakers you hook up to it are lower than 6 ohms, it may work until you turn it up, then it will either shut down or burn out the finals. If you hook up a speaker that has a higher than 16 ohm, it will not get very loud, and it shouldn't hurt the amp.
1. Check the mute button - some computers have a hardware mute on the case. Also check the software mute button.
2. Check you default sound output device in the sound or audio control panel. Which device is the default output device?
3. Does windows "chime" when it starts?
instead of finding a low frequency line to attach to your LOC (line output convertor) use the built in crossover on yours subwoofer amp or an external crossover to limit the frequency range going to the subs
This will depend on whether your sub-woofer is powered (has it's own built in amplifier) or not.
If it is not powered it will need connecting to an amplifier. If it is powered you will need a line level output either on the amp or the mixer.
Many modern amplifiers (and some mixers) have a dedicated output for sub-woofers in which case this is the best place for it because the higher frequencies will have been filtered out.
Some high quality amplifiers like the JAMO MPA 101 have a filter switch and adjustable filter level for powering sub-woofers. You then just connect the speaker to the speaker terminals in the normal way.
Otherwise on a p.a. mixer you could use the main output, one of the auxiliary, monitor or sub-mix outputs. If you are not using the main output you will need to route signal to the appropriate output accordingly. Either way your output signal will cover the full frequency range - your subwoofer may have built in filtering or you may need to use some sort of crossover to split the signal between the sub-woofer and the rest of your speaker system.
In general, the PC's soundcard and video capabilities will determine the answer to the question. And which direction you want to run. Is the PC a source or the end-unit or both? Your PC hardware and software documentation would describe various scenarios.
The PC is a common source of audio. Any PC should have a minimal headphone output, which would be functionally the same as the analog L/R speaker output. Simply adapt the cables for RCA connection to your audio system, get into yourt PC's sound controls (usually proprietary), max out the volume and set its output for something like FULL range speakers.
Run it to any available Line Level input on the HT.
Digital outputs, same same.
Sending sound TO the PC will depend on IT and the software it uses.
Note: The default audio setting for your notebook is Speakers / Headphones. You must change the audio output back to the Speakers / Headphones option for the computer to once again be able to use the internal speakers and headphone jack.
I have lenovo notepad 3000n100 with winXP sp2. I downloaded realtek audio from ibm site and installed. Now sound is coming at my output port but the in-built laptop speaker is not giving any sound output. The hardware is ok as the sound was coming at in-built speaker before formatting. The previous audio driver set up file i have lost. Plz help.
Please connect the headphone to your system and check the sound quality,If it sound good then the connection of the speakers are not ok. This system has HI & low frequency output. Connect woofer to LOW frequency output and tweaters to HI frequency.
please take trouble to vote for me if this solve your problems
