Yes, even better!

the extent of my testing equipment is a multimeter. I do not own or have access to a scope Assuming that you have an Android smartphone, you can measure the acoustic frequency response with a free app called Sound Analyzer Basic. Just send the speaker some pink noise, place the phone so that it ...

Unfortunately that's not a subwoofer you've linked to. That's a TS2xx series speaker. and as such has a more powerful amp section, so will have different components/design. Here's a link to the TS115a service manual. https://www.scribd.com/document/560893271/ts115a-mkii-service-manual-v1-0 To be ...

Details of the speaker can be found here: https://www.altoprofessional.com/products/ts115a (The crossover frequency is 2.5 kHz) I can't find a schematic for this speaker, but I suspect that the dual channel power amp board might be similar to the one in the TS15S subwoofer, whose service manual can ...

Does anyone else think that it would be a good idea to check all of the capacitors in-situ with an ESR meter before swapping them? It might save a great deal of time, and the associated risk of introducing further faults.

Again, not sure what all that means. I do have a gmail account as well. Dave. Hi Dave, That's what I meant. Are you accessing your two email accounts separately in a web browser? If so, you might find it more convenient to install email client software on the PC that will automatically download ...

I am not sure that BT intend to support their email service forever. This also may apply to Plusnet and the other legacy brands that they have bought. It may be wise to at least get another email service from one of the big providers, so that you are not left high and dry. In my experience Mozilla ...

I'm assuming that you have already tried a different mixer to eliminate that from the equation, and that you have turned off any Microsoft "enhancements" such as "spatial sound" etc. When you have created frequency plots of each speaker, you may want to see if you can connect the XLR outputs up to ...

It is extremely improbable that several speakers, used in different systems and, presumably, for different service durations should all fail in the same way at the same time. Two failing would be improbable, that 9 have is almost impossible. Much more likely that the cause of the phenomenon is ...

This seems a bit odd. Nine speakers all failing in the same time frame with the same rather obscure fault? These appear to be similar to other Alto speakers, with two class D amps, an active crosssover and a limiter, so an electronic fault is possible, but nine times? Is it possible that the speaker ...

Yes Logic plays through the internal audio card. Thanks. In that case, I suggest that the OP (temporarily) configures Logic to use the internal sound card instead of the external audio interface. If the symptoms go away, the problem may be in the external audio interface, or its driver, and a new ...

Hi again !! Thanks for the replies. Jimmy B , the playback just goes silent . Chromeman , i am on sequoia . So it was a cheap sound interface , it was discontinued and in my case its supposed to work with the latest Mac OS and logic . I am betting with the Babyface everything Will work rock solid ...

I get no sound when i play my controller , but logic registers . The song plays back and when i click a note in piano roll it sounds . What is wrong ? Just to recap, I think that you are saying that you can record a track in Logic, and the track then plays back correctly. The only issue is that the ...

What is the current view of Super8 midi controlled looper in Reaper? Asking out of curiosity only, as I don't need anything so complex.

I don't need remote switching as I designed the sockets to be reachable. So really just something that plugs into the mains sockets and is designed for regular switching. Is this a thing? To pick up on AJ's earlier post, it doesn't sound as if the socket outlet is failing to switch the current. (If ...

Anyone? When I went through a similar exercise I remember that I had to go through a lot of on-line guides and YouTube videos before I had a good understanding of everything that was involved. I have never found a guide that was truly comprehensive. One thing that I would say is that when doing this ...

It would be good to understand how the manufacturer intended this looper to be used. Surely they tested it with a guitarist or two?

I agree with Ajay. It is quite likely that one of the power strips has a safety ground continuity fault, which may be intermittent. Whatever the fault is, this is not something that can be "lived with", as an important safety feature may be neutralised. It needs to be sorted out quickly. This issue ...

In case it might help, I tried the same experiment here using a cheap digital multimeter. I am seeing 0 volts on the AC voltage ranges (which can measure 0.1 volts) and a maximum of 0.1 millivolts (the smallest number that it can measure) on the DC voltage ranges. This is on the second power strip ...

This should be investigated and fixed immediately, although not fatal "in most cases" it's very unpleasant and could be indicative of dangerous faults somewhere in your mains wiring. Or floating mains voltages, make sure your system is grounded. +1 to this! Also the basis for any installation, even ...

Thank you for all the advice - I have now taken on board comments and worked out how to set up a stereo recording in Logic Pro. I would now like to work on the acoustics in my room and possibly look at getting some GIK sound treatment boards. I hope that you have made some simple test recordings to ...

Definitely looking forward to a "Wonks guitar furtling" article in SOS though (assuming Hugh and Wonks can be persuaded). This would be of interest to many SOS readers including keyboard players like myself who of course have some guitars but are largely clueless about whether they are badly set up ...

Thanks to Wonks for the very detailed reply and pictures. So it seems that IF (and we don't know yet) the saddle is touching the trem pivot post, there are several options to repair the problem. I'm not sure that I would tolerate the need for repairs on a rather expensive (and presumably new) guitar ...

I cannot push a piece of paper between the saddle and the post and I strongly suspect the culprit is vibration passing from the post on to the saddle and screws assembly. But the intonation is good with the saddle where it is! This is more of a question than a statement, since I don't own this ...

One more thing to try if the above doesn't sort the problem. It's possible that there might be something loose that's vibrating in tune with the G string. Try playing it without an amplifier, and see if you can hear anything odd.
