Loosing sound / distortion

My Legacy Series II amp, model LA 1020 has two problems. 1)The subwoofer is bridged and now won't play unless I play with the crossover switch. It will operate for a minute or so, then shut off. Ive checked connections, reversed channels to eliminate the head unit (JVC digifine) 2) The unbridged side is giving me some distortion intermittently in just the right channel. Again I have reversed the channels, etc. as above and the problem remains in the right channel. The speakers can handle well above the stated RMS and peak levels. I removed the cover plate and used contact cleaner to try on the switches suspecting possible oxidation. The only thing I have not done yet is try to use a home audio/video amp to make double sure it is not my head unit. Any ides or is my amp (or switches) just going?

If the sub channel is shutting down, there is a problem with that channel. The unit will shutdown to prevent further damage. This unit will need to see a service bench to determine the defective part(s).

I got this sub used nothing else. connected it to my tv and fine. loud and clear but I hooked speakers up to it thinking they would play and they dont...only the sub. Am I missing something?


Are you bridging your speakers to your subwoofer? Or do you have them running off of a amplifier? If your bridging it from your subwoofer it will only send out subwoofer frequencies. Or if you have it running off of an amplifier, your resistance on your speaker coils might be too high, or low.

No sound from bose 321


You need to localize. Play a DVD, does the same audio cutout happen? Do you have the center dvd or the left mounted dvd? The console unit has input jacks for external audio inputs, put an external audio source in and see if the same cutout occurs. See if the external output jacks lose audio or just the system speakers, including subwoofer. This may help localize which unit has the problem.

Is the console stacked above or below other electronic units, it may be a heat related cutout? Reseat all your interconnect cords, I have seen corrosion occur on the square connectors.

These are expensive to have repaired, good luck. If you're daring enough, you make find free service manuals on websites like Elektrotanya, hifimanuals, hifiengine, and eserviceinfo (.com)

Setup help for record player (Pro-Ject Carbon Debut) and pre-amp (ART DJPRE II) into Denon AVR-1909. I have everything setup properly, but I cannot get the subwoofer to turn on with my 2-channel settings...


In two channel mode, there will be no subwoofer signal unless you change the front speakers to 'small'. If you set the front speakers as 'large' then the full frequency spectrum will be sent to the front speakers, and none to the sub. Switching from bluray may keep the surround configuration until you restart as you mentioned.

Get a separate amp for the 901's and the rest falls into place.

1,2, 5) Place the 901 Active EQ between the pre/main front OUT of the receiver and the TFM-55X. Attach the 901's. Keep track of the jumpers you remove from the receiver. Or replace the jumpers with RCA splitter cables so you still have pre/main connection but can share the output with the TFM.

3) Pinnacle subwoofer (self-powered?) to the subwoofer out of the receiver.

4) Bose (AMS???) 5. As surrounds on the receiver. Place the sub module toward the rear so it mates sonically and directionally with them.

What? No center speaker? I'd get something more robust with bass capabilities, like a pair Bose 301 series 1's because the tweeters face in one direction only.

Except for the amps and the cube stuff that is essentially what I have. 6.1 with full-range speakers everywhere.

Can I run two E.V. Eliminators (1-15 and horn...8 ohms) in series from the bridged output? What my wattage be? I have an EMX5000 powered mixer. Jim Price pocket218@gmail.com


Hi pocket218

Probably not the way to go about hooking it up. running speakers in series is not very practical with PA gear. The connections get messy to make as you need adaptor leads, and it is something that is seldom ever done.. When you use bridge mode it uses left and right channel together to drive the one output, combining the power. Best bet is to run the EMX5000 in stereo mode, and connect 1 speaker to each channel. You may have been trying to reel in extra power from using bridge mode, but the power amp stages in the EMX will only ever be able to deliver the same MAX power whether in bridge or stereo. the best way to get maximum power and sound pressure levels from the unit is to hook TWO speaker boxes to each channel, you get the combined increase in efficiency of the extra speakers and run the output stages at 4 ohms to get absolutely all the power available
If you have any questions about it, feel free to ask me, happy to talk to you further about it.

regards
