| System needs more watts?? Hi DB,Your setup is fine. The PI models are what are known as input transformers, which have to be connected to the destination device (the device whose input they are connecting to) via a short length of cable, regardless of whether that cable is... | |
| Gain for HO MC or MM cartridge? I've used 40 db phono stage gain with cartridges rated at 3.5 and 5.0 mv, with line stage gains ranging from 12 to 21 db. Results have been fine in all cases.Regards,-- Al | |
| Strangest problem I've ever had Metro gets all the credit. All I did was to describe how to use the meter.Glad the mystery is solved!Regards,-- Al | |
| System needs more watts?? Following up on my previous post, based on the comments by Victor of BAT in this thread it appears that the concern I mentioned about possibly losing 75% of the amp's power capability when providing it with a single-ended input is not applicable t... | |
| System needs more watts?? If I'm not mistaken, your preamp has only unbalanced inputs and outputs, which does not seem ideal for use in conjunction with your fully balanced amplifier. For that matter, what is the means by which you are connecting the two components, as I b... | |
| 10K$ Speakers for 845 SET amplification Second the Daedalus Ulysses, especially if it includes the "all-poly" crossover that was introduced about two years ago. That revised crossover, which was originally offered as an option but is now standard on the Ulysses, resulted in its already ... | |
| Strangest problem I've ever had To check for a short in the wiring you have to disconnect both the speakers and the amplifier, so that the wires are connected to nothing at either end.Then set the meter to R x 1, and touch the two leads of the meter to each other. There should b... | |
| Strangest problem I've ever had Yes, that is a head-scratcher indeed. Some questions and comments:1)In my experience as an electrical engineer, often when inconsistent and puzzling symptoms are present it turns out either that the problem is intermittent, or there are two differ... | |
| Anyone compare DH Silver Sonic to WW Silver USB? My opinion on the matter was expressed in Tony's other related recent thread. A point I would add relates to the fact that both of the cables being asked about in this thread emphasize accurate control of impedance (or more precisely, characterist... | |
| Amp preamp impedance matching...can anyone explain? Is there a limit to how high these ratios or the power-in should go, before it sounds bad?No, not that I can envision.Regards,-- Al | |
| Sub Woofer Hum... This One Puzzles Me Is shorting the + and - terminals on the unused sub channel simply a matter of a short run of wire terminated with bananas inserted at the inputs?Yes :-)It would be prudent to have both the amp and the sub unplugged when you are inserting it.Best ... | |
| Sub Woofer Hum... This One Puzzles Me Hi Scott,I hadn't been envisioning that the sub only accepts bananas. It looks like at least some versions of the MC7100 have screw type terminals, although I see that you referred to banana terminals on it. If the terminals on the amp are either ... | |
| Sub Woofer Hum... This One Puzzles Me Hi Scott,Yes, that's certainly a puzzler. I see that the 2w series of subs is described as using some kind of feedforward error correction. Perhaps that is allowing small amounts of leakage between the AC line and the circuit ground of the MC7100 ... | |
| Sub Woofer Hum... This One Puzzles Me Hi Scott,Are you saying that the hum occurs even when the sub is unplugged from the AC and the amp supplying the signal to the sub is also turned off? If so, are you sure that the hum continues to occur after several minutes have elapsed, when the... | |
| Audio experts help Decibel output. Hi Bruce,What will double, as seen by the amplifier, is the impedance that each speaker has at any given frequency. "Impedance" reflects the combined effects of resistance, inductance, and capacitance at that given frequency. Assuming that the two... |
