| Can I tweak L-R balance by differntial biasing? Hi Michael,I'm not 100% certain, but I don't think that approach would accomplish what you want. I believe that gain, which is what you are trying to change, will vary very slowly as bias is adjusted. If you want to unequalize the gains by say 2 o... | |
| just starting - mac vs. windows computer source? Tim (Mitch2), a thread that I think would be very worthwhile reading is this one, especially the comments by AudioEngr (Steve N. of Empirical Audio), whose opinions and experience certainly warrant a great deal of respect IMO. Several of the other... | |
| Bass leaves after amp warms up? Yes, I should have stated the cautions that the amplifier should be unplugged from the AC when the cover is being removed, and nothing internal to it should be touched whether it is plugged in or not.Regards,-- Al | |
| want to hook up 2 spkrs for each left and right. A P.S. to my previous post. A solid state amplifier will only be able to deliver half as much power into 16 ohms as into 8 ohms. So depending on the power rating of your amplifier, to avoid the possibility of clipping the amp when using a series c... | |
| want to hook up 2 spkrs for each left and right. Yogiboy is correct.It should be mentioned for the record, though, that series connection will not generally give good sonic results if the speakers are not identical or very similar models. The reason being that the frequency response of each spea... | |
| Bass leaves after amp warms up? Don't know. Since it is a British manufacturer, they might be metric. If they require an Allen wrench, this writeup might be helpful, as it indicates which sizes are and are not interchangeable between millimeter and inch-based sizes.Regards,-- Al | |
| Bass leaves after amp warms up? The amp doesn't feel hotCan it still be running hot?Without being familiar with the specific design, we probably can't rule out the possibility that some particular point or points within the unit are getting too hot, even though it seems cool on ... | |
| Bass leaves after amp warms up? Ralph, note that all three of the "amps" that have been tried are integrated amplifiers. There is no preamp, although presumably there is a phono stage that is not listed in Fishing's system description. But the phono stage and turntable setup wou... | |
| Bass leaves after amp warms up? Currently just listened 2 complete LP's without losing the bass using just the right speaker connected. I don't know why that is.Connecting just one speaker will certainly make life easier for the amplifier, and reduce the internal temperatures th... | |
| Simple Biamp question Take a look at the rear panel of your speakers, and see if there is a statement indicating "remove both links for biamplification." I found this writeup, which shows such a statement on the rear of what is probably the Allison One, although the Fo... | |
| Bass leaves after amp warms up? 04-11-13: Fishing716After enjoying the system sounding great for 2 hrs the bass dried up. I waited 1 hr.tried again but no improvement. Turned off amp for 1hr.returned & the presentation was still awful. I also observed when I change source on... | |
| Bass leaves after amp warms up? My MF amp should be adequate @ 200wpc or noMy strong suspicion, consistent with points that were made earlier by Foster_9, Mapman, and others, is "no." As I previously indicated, the three amplifiers you have tried either do not have a 4 ohm ratin... | |
| Bass leaves after amp warms up? FWIW, I'd just like to emphasize that the impedance curve I linked to earlier shows that the speaker's impedance is in the vicinity of 2.7 ohms at several frequencies in the deep bass and the mid-range, and is less than 4 ohms throughout most of t... | |
| Simple Biamp question Why would the absence of independent crossovers make them unsuitable for biamping?It is conceivable that if the speaker is not designed to be biamped its design could be such that it would short the two amplifier channels together, either directly... | |
| Simple Biamp question I have no idea why the fact that the amps are stereo would be an issue. The fact that they said that lessens their credibility, IMO. One conceivable issue, though, is that there are some speakers that provide two sets of binding posts for biwiring... |
