| Subwoofer insight. There's a reason you see RELs with 2 channel high end systems at the showswhere some of mostest, awfulest sound on the planet is purveyed.IMO, any sub w/o a continuous phase control, polarity invert and multiple slopes is a toy. | |
| Subwoofer insight. ATC SCM19 has a published spec ofFrequency Response (-6dB): 54Hz-22kHz Even 1000w is never going to get low end from it or any similar 2-way.Power requirements fall approximately 50% per octave. Using the SCM19 as an example and rolling the bass ... | |
| Subwoofer insight. These low frequencies are inherent in the acoustic resonance of large spaces. Therefore present in all music that is well recorded in a large space. Nonsense! It’s only present if the material was not filtered, which was often SOP for records. An... | |
| Need help in trying to trace cause of distortion Download REW https://www.roomeqwizard.com/ and purchase a calibrated microphone https://www.parts-express.com/dayton-audio-umm-6-usb-measurement-microphone--390-808Learn how to use them and you will be able zero in on problems like this in sho... | |
| Subwoofer insight. Simply visit their website and they have a page where you can enter the data of your room size and speakers and they will match you with the perfect sub Nonsense!Limited speaker brands, model choices and room parameters. An utter waste of time!So... | |
| Subwoofer insight. A simple 6db/oct XO HiPass is easy to make.See http://www.ielogical.com/assets/Audio/PassiveXO1.png for a picture The circuit is just a Y with the appropriate cap in the main amp line.Fc = 1/(2 π R C) where R is Ω and C is in F. 10nF is 0.000,000,... | |
| Subwoofer insight. But I guess "coloring" the sound of the sub(s) the same as you are the loudspeakers is a defendable notion. Nope. Only true if the subs are 100% transparent.Doubly untrue on tube amps due to transformer/main interaction. | |
| Subwoofer insight. Why is a subwoofer high level connection genius?IMO, it's as hopeless as trying to mate a whale with a mackerel.Rolling the low end in the mains and properly integrating phase and level therewith blows the doors off padding the low end unless one ... | |
| Beware of NAD M3 Fire Hazard As far as the voltage I am just guessing it is 110. I thought everyone is either 110 or 220 A G R E A T many devices today are still rated 117v. [NAD M3 is 120v]120v became the US standard in 1967. 120v +5% is 126v which is 107.6% of 117v. It’s n... | |
| Beware of NAD M3 Fire Hazard Shaking down a supplier for a 10+ year old+ electronic product, with a history you don't know (not the first owner), that could have experienced surge events, or other events outside the suppliers control, is not cool. +1 | |
| Beware of NAD M3 Fire Hazard The local line voltage is 110 The unit is rated 120v. Nominal is ±5% - 114v to 126v.Running on 110v increases cap ripple if load high current delivery is required. Ripple increases heat. By chance did the unit smell hot? Diodes usually fail op... | |
| Subwoofer insight. Roll the low end out of the mains with a simple cap XOver, say 80-100Hz.Check out http://www.ielogical.com/Audio/SubTerrBlues.php for integration advice.I ran a single 10" w TC-50s in 16 * 30 * 7 to good effect.Adding good low end increases real... | |
| Beware of NAD M3 Fire Hazard I will never purchase an NAD product again. EVERY product suffers one-off failures.NAD has made millions of units with very high reliability and excellent sonics for very reasonable prices. NAD are well engineered. Electronics are made of comp... | |
| Dumb break in question... Because turn the amp off, now you are back to the same situation where the circuit is open and nothing is happening. Thanks, millercarbon. Set my day off ROTHFLMFAO!Al is 110% correct, as usual.expose it to a powerful magnetic field and then take ... | |
| Adding shielding to existing cables Pro tip:@ millercarbon - my company designed, built and installed recording studio signal cabling.Gear is always connected EXACTLY as Eric stated. Only exception are phantom powered microphones. |
