| Negative Feedback a deal killer? "better dynamic range then all others based on tiny switching power supplies (again - huge exception is Jeff Rowland)" Not only that most (if not all) of Rowland Icepower amps use SMPS supplies but he uses them as well in Capri preamp and new gene... | |
| Signal Direction XLR to RCA? Which way? Rickschell - it's easy to remember if you know the reason. XLR input sides (of component or cable) are always female to prevent touching input (recessed contact). In addition XLR connectors are locking. It was intended for studio/concert environme... | |
| Negative Feedback a deal killer? "50us/0.2us = 500" ? | |
| Can volume/selector pots be switched out of a pre? If it happens again you might try special lubricants/cleaners:http://www.amazon.com/CAIG-DeoxIT-FaderLube-Lubricant-oz/dp/B000H2G5R8/ref=sr_1_1?ie=UTF8&qid=1287627288&sr=8-1 | |
| Music you like but rarely listen I never listen to one CD I have: Music of Indonesia "Songs Before Dawn" (always asleep). | |
| Negative Feedback a deal killer? Unsound - As I understand it class D doesn't need a lot of negative feedback since duty cycle is much more linear than transistor voltage in class AB output stage*. In addition it has inherent low output impedance since speaker is always connected... | |
| What if you designed your ultimate speaker? A good question to ask is: Why nobody else is doing it (1/2 octave design)?Do you know something they don't or is it simply not cost efficient for others to manufacture? Is it for you? Dealer markup is often in order of 50%. Company markup on comp... | |
| Changed Speaker Placement NOW BOOMY Josh358 - That's exactly my situation but EQ won't help me getting rid of echo. What happens at lower frequencies is also echo in a sense that reverberation changes sound (bass attack, decay etc.) | |
| Changed Speaker Placement NOW BOOMY "I've never sat in front of Hyperions, but they look great."Timlub, you make me feel better. The only thing I didn't like about Hyperions was black piano finish and coffin like shape. Now it is slowly growing on me. I even realized that possible s... | |
| Changed Speaker Placement NOW BOOMY Timlub - There is a pretty good article here : http://www.ethanwiner.com/acoustics.htmlIt shows that my material (John Manville 817) has two times higher absorption coefficient at 125Hz than lighter 814 material (similar to common Owens Corning). ... | |
| Changed Speaker Placement NOW BOOMY Timlub- are you talking about corner traps? For the walls I have thin wood (pegboard like) 2'x4' boards and 2'x4'x2" high density fiberglass panels to glue on and wrap in fabric. I'm placing 8 panels on one wall and 4 panels on another (planning t... | |
| Changed Speaker Placement NOW BOOMY Timlub - Yes, corners are the worst (I have window in one).Damping materials work effectively to about 100Hz at 2" thickness. Further down it requires going to 4" panels (dense fiberglass) and positioning them 1/4 wave from the wall. I'm in proces... | |
| Amp output is wired in series vs parallel? Shouldn't it be 2x voltage in bridged? | |
| Changed Speaker Placement NOW BOOMY 12' distance should give resonance at 48Hz while 26' span amplifies 22HzF= 1150/(2xd) where 2xd is twice the distance (wave has to travel forth and back to add in the same phase). | |
| has anyone ever listened to a 45lp at 33.3 Al,Placebo effect is very strong when mistakes happen. Many years ago friend of mine invited girl home and offered to play some Bach organ music from his father LP collection. After a while it started to sound very strange so he glanced at rotatin... |
