I suppose I could have left the 24v relays there and could have made them work via a 12v trigger if I was willing to use both a 24V wall wart and add a relay to switch the 24v input with the 12v trigger. The 2x60 amplifier has this resistor on each amplifier board (even though only one uses it) so that the boards are interchangable. My first hunch was if I could possibly just bridge the connections for the override button so it’s always pressed — unfortunately this simple solution didn’t work. It takes time for newly-industrialising countries such as Russia and China to develop quality control techniques comparable to the older industrialised countries.

Other users have done much more extensive modifications to this amp including replacing relays or even removing relays entirely. You might phone the company to make sure that the two RCA ends connect one to the hot pin and one to the cold pin of the XLR. binoculars are a bit strange looking with a rounded top prism housing and black stippled barrels and body. Rather than claiming 220W it seems more reasonbale to expect 200W given that it is using the bridge circuit from the 2x60 amplifier.

Given all the protection and diagnostics this board is capable of, I wanted to keep it intact as much as possible. it fit so nicely in the FOV that I stood there looking up at it for quite some time because it was fairly high in the sky and quite clear because of the altitude it was at. The Moon looked good earlier when looked at briefly, lots of detail but some small limb false colour. I was curious and discovered that this is EXACTLY what crestron did on the 2x60 amplifier except the crestron has input filter capacitors on both the non inverting and inverting inputs. With more than 300 square inches of heat sink surface area per stereo module, cool, quiet, and reliable operation is ensured.

Well, you can create two out of phase signals externally, and feed them to pairs of inputs on the amp. As far as the OPTICS go, these were very sharp almost to the edges of the FOV but I would have to say that the Pentax PCF WP II's have a flatter FOV towards the edges, but not in a hugely noticable way.Since Alexa doesn’t have automation triggers for starting/stopping music playback, right now I have to either ask Alexa to turn on the Crestron amp, or pop into Home Assistant to manually turn it on. Does the current increase with such a connection in parallel and how does the Damping Factor change. Normally this would be setup by the AV installer as part of a whole-home control system in a rack full of Crestron gear, programmed by the installer so the home owner can easily control anything in the house. Incidentally on another winter early morning trip to the observatory when I came out and locked up there was a large white hare sitting upright on this granite rock about ten feet from me. Practical Machinist is the easiest way to learn new techniques, get answers quickly and discuss common challenges with your peers.
