I would look on head-case. Now for something completely different in the diy section. Tread lightly and you'll be just fine.

Similar reasoning as to why some of us on HC felt that a 5 pin XLR should have been the standard for balanced connections on full-size amps and not the 4 pin. This would have allowed simple construction of adapters for standard single ended headphone connection as the ground would be available...

By "single ended" I mean normal 2 channel stereo, as you would find on most audio equipment with pairs of RCA connectors, or normal headphones with a TRS plug. Most home audio equipment has the grounds of the inputs or outputs connected together. Older headphones would normally be wired with a 3...

The Moon audio article is correct. A balanced amplifier will be providing 4 amplified signals: L+, L-, R+ and R-. A single ended adapter will tie the L- and R- together for "ground". Since the amplifier is actively driving these signals, shorting them together will not make the amplifier happy...

Stupid question: I just got a pair of Ether C Flow (1.1) and these have the angled pads. Is the thick part of the pad supposed to go to the front or the rear of your head? I assumed the rear, but these have the pads on opposite. Thanks! Oh, also, someone was asking how you tell them apart (C...

Interested. Would you consider shipping to the US (Chicago area)? Thanks, Chris

Yep. Found this, which matches their port descriptions for the headphone jacks: You would not connect the sleeves of either 1/4" to anything. Balanced connections don't reference to ground, so not needed here. The + connections would go to the 1/4" on the left, and the - connections to the...

A little late on this, but one reason why I modified a version of Kevin's protect board to incorporate a mute switch which completely disconnects the phones via the protect relay. Also did the same with Amb's board for SE only use (on my DynaFET). This of course won't help you regarding live...

The output stage of the CFA3 doesn't really look stripped down from the CFA2 to me, but I haven't compared them closely. On the CFA3 that I worked on, I couldn't tell much if any difference between the SS vs. ZF modes either.

Do you have a multimeter with ohms functionality? If so, check continuity between the - speaker terminals. If 0 ohms (or <1 ohm), you should be good. If not, then the - terminals are not common and the 4 pin XLR would be prudent. I'd also ask this question somewhere like diyaudio, in the Pass forum.

Not necessarily afraid of them. I've built around 5 of the SS Mini Dynalos, which are pretty much all SMD. The problems with SMD include the difficulty in troubleshooting them, parts removal/changeout (depends on device footprint), problems with matching devices (resistors/transistors), etc. An...

After getting the baffles and pad rings cleaned up, and figuring out how much force, best tools, etc., I got em. I used a small chisel and once I got a corner up, I just went around them and they popped right out. Surprising. I'm not in a big hurry on these, so will start sanding. Might use some...

Got a set of the baffles and pad rings cleaned up. It looks like the support settings used were a bit aggressive, as there was a solid layer of material that I could tell shouldn't be there, but was not latticed or whatever you call if for normal support material. After some prying, I was able...
