| Tone controls- to use or not? As Reubent said..."Use the tone control. That's what it is there for".You might find an equalizer to be more effective because you wouldn't be stuck with the "hinge" frequency that the preamp designer chose. For example, if your hearing rolls off ... | |
| How to control long decay of B&W woofers ? A drum does not go silent suddenly. It has a decay time, perhaps increased by the recording venue. Maybe what you hear is true. | |
| Pure class A amplifiers = "slow" amplifiers? Johnk...Fostex 31.5 = cone area! Also, Fostex 31.5 = $2535.75 as of April 07. Probably more now. | |
| Pure class A amplifiers = "slow" amplifiers? Johnk...Although Maggies aren't high efficiency speakers, they do have very small diaphragm excursion, and I believe this may be a lot of the reason they sound good. When I designed a cone driver subwoofer system to go with my Maggies a prime crit... | |
| Up grading power amp... Mono blocks or stereo amp? Atmasphere...Another important advantage of monoblocks, at least for high power units, is that they are not too heavy to pick up! That, and the short speaker wires is why I have monoblocks.I think that the shared power supply thing is a bum rap, a... | |
| Pure class A amplifiers = "slow" amplifiers? The bug-a-boo about A/B amps is crossover distortion where, as the waveform crosses zero and changes polarity, one output transistor turns off and the other turns on. The very first transistor power amps caused distortion of the waveform as this h... | |
| Pure class A amplifiers = "slow" amplifiers? "Speed" or more properly "rise time" should never be a problem for audio amps. After all, both tubes and transistors are used at radio frequencies. | |
| Pure class A amplifiers = "slow" amplifiers? Guidocorona...Believe it or not audio can be speeded up without the tonal change that results from overspeeded playback...but no using a simple amplifier. It takes some digital processing. It is a fact that our sense of hearing can recieve and und... | |
| Shorting the speaker wires My CarverPro ZR1600 amps have Neutronic output terminals, which I have never used. I use the binding posts with bare wire terminations (or should I say non-terminations). The Neutronic connectors are a twist-lock design, with a contact wiping acti... | |
| Unipivot vs Linear Tracking The linear tracking arm is without doubt a better setup than any pivoting arm, but the friction of the arm when it travels has to be reduced to near zero. Most linear tracking arms use an air bearing which is complex and delicate, and the air comp... | |
| 45 vs 33.3 RPM In theory 45 rpm should be better, but theory does not always show up in practice. Without doubt the shortened playing time is a nusiance. | |
| digital equalizers Of course there are some who will put down anything digital. You can put digital in and get it out from the DEQ2496, so that removes concern about A/D and D/A conversion. (By the way they are excellent 24 bit 96KHz devices). The equalization and o... | |
| digital equalizers Sounds like you need an equalizer. You can buy an excellent one for only about $350, including calibrated mic. At this price hands-on (and ears on) experience beats any opinions you may get on this site.Behringer DEQ2496, available through www.sam... | |
| Ground Loop Timrhu...I have been described by fellow workers as a walking encylopedia of useless information. It makes life interesting. | |
| Ground Loop In audio electronics a "ground loop" exists when different parts of the circuitry, say preamp and power amp, are separately grounded, creating a loop. This means that the signal reference ground may be different in the two places, and the usual re... |
