| cabling a subwoofer to a NAD C356 integrated amp Good! That's a comparison that is well worth doing. As you realize, whether or not it is preferable to high pass the signals provided to the main speakers involves a system dependent tradeoff between how well the speakers and the power amp can han... | |
| cabling a subwoofer to a NAD C356 integrated amp Hi Loomis,I think you are referring to connecting the pre-outs to both the sub and to the inputs of the amp's power amp section, rather than connecting the pre-outs to the sub and the sub's line outs to the power amp section. If that is not the ca... | |
| "Against design" why do so many box/driver speakers use MDF instead of real hardwood? See the answers by Lou Hinkley of Daedalus Audio and Jonathan Weiss of Oswalds Mill Audio ("weisselk") in this thread.The main reasons seem to be (a)cost, and (b)difficulty of ma... | |
| cabling a subwoofer to a NAD C356 integrated amp For the B set I have my cables set for both right and left positive to go to positive in on Gallo, same for left.The Gallo subs, or at least those that are presently listed on their website, have separate high level inputs for the two channels. So... | |
| Best car audio, Burmester? highly disapointed It sounds like you've probably done a thorough job of going through the setup menus. But just to be sure, have you optimized all of the settings that may be relevant? That would include "listening position," "smooth," "surround," "live," "sound co... | |
| Need help RCA Interconnects but new Balanced Gear There are some high end interconnect cables that differ between XLR and RCA versions only by virtue of the connectors that are used. In those cases the cable usually contains two conductors that are symmetrically placed within a shield, with one o... | |
| Ssssh, is your tube preamp really that quiet? A point that hasn't been mentioned yet is that our ears, or at least MY ears :-) are significantly more sensitive to high frequency hiss when it is firing into them from the side, rather than emanating from a direction that is closer to the one th... | |
| REL subwoofer with old McIntosh tube gear? I'm saying that if I am correct in assuming that the red wire from the sub is connected to the 8 ohm tap of one amp, and the yellow wire from the sub is connected to the 8 ohm tap of the other amp, then what you should try is connecting the black ... | |
| REL subwoofer with old McIntosh tube gear? When connecting a single sub to two monoblock amps REL generally recommends connecting the sub's black (ground) wire to the chassis or other ground point of the preamp. The red and yellow wires would be connected as they apparently are presently, ... | |
| REL subwoofer with old McIntosh tube gear? I'm trying to get rid of a 60 cycle hum when the AMPS [emphasis added] are on... More detail is needed. First, are you saying that you are using a pair of monoblock amps? Also, what model is/are the amp or amps, and the sub? And am I correctly int... | |
| The sound of my new electrical service: Day 1 So in US< in essence, isn't "clean" AC power predominately 60hz, and any variations from this "noise"?Yes, except that I would say "noise or distortion."Can an oscilloscope make this distinction?Yes, mostly. It can certainly distinguish between... | |
| The sound of my new electrical service: Day 1 Mapman, let's take the BrickWall surge suppressor/line filter that I use as an example. Its specs that are relevant to noise filtering, which are certainly measurable as well as probably being analytically predictable to a reasonable approximation... | |
| The sound of my new electrical service: Day 1 03-20-14: MapmanAl, explain please why that would not be useful?Hi Mapman,I think oscilloscope measurements would be unlikely to be useful because:(a)The noise and distortion that is present on the AC will consist of a complex and probably time-va... | |
| The sound of my new electrical service: Day 1 Harv, I see in some of your past posts that you are probably using a pair of vintage Fisher monoblocks. What model would they be? And perhaps a bias readjustment is in order, if the amps have adjustable bias and if my suspicion is correct that a c... | |
| The sound of my new electrical service: Day 1 03-19-14: MapmanBeyond the multimeter, which is a logical first step, is there an affordable gadget out there that can be used to actually measure AC line noise? That would take a lot of guesswork out of the equation when attempting to determine v... |
