Re: Breaking speakers by turning off a synth

the problem is that when do you hear a loud thump the damage may already be done. That would have to be some pretty high energy thumps going on... I've had all manner of electric music device in the studio at one time or another, and turn-on thump is the last thing I would expect to damage speakers...

Re: Breaking speakers by turning off a synth

Power off the speakers/amplifier first and wait 15-30 seconds before powering off things upstream. The power supply capacitors in the amp typically take that long to discharge, and until they are discharged you can still propagate "thumps" through to your speakers. Generally if you don't hear a thum...

Re: Should I replace the caps in my SY77?

Unless it's a brand known for spiky power supplies, e.g. ARP, it's probably not necessary to replace the tantalums. If they were put across the supply rails for the express purpose of lowering noise from digital chip current draws, replacing them with electrolytics will somewhat defeat that purpose ...

Re: Should I replace the caps in my SY77?

Thanks for the very informative post, Dan. I'll hold off for now; I'm pretty sure there are no tants in the PSU. For what it's worth, the tants wouldn't typically be in the PSU; they'd be sprinkled throughout the boards driven by the PSU. Their purpose is typically the reduce noise on the power sup...

Re: Should I replace the caps in my SY77?

I agree with what Hideaway said (especially concerning ARP); here's something else that might be helpful. Generally the only electrolytics I scrutinize are the large-value filtering caps in the PSU, especially those that are next to heat sources -- regulators, heat sinks, etc. or where the PSU is in...

Pretty sure those are what goes in the rack itself, not what would go on the equipment being racked. But useful in their own way.

Re: Korg DW8000 opinions please

It's the lack of the digital delays, and that the Q parameter on the filters isn't controllable. However, there are a couple other areas where the DSM-1 is better, so the choice depends on what you value the most.

Re: Ship 'em or sell 'em? - US/EU voltage wonderings

Should you decide to carry over the Space Echo, its motor is a DC brushless type, driven by an electronic circuit that provides the variable-speed capability -- and would not be affected by the change from 60 to 50 Hz. Ordinary AC motors need to have their voltage further reduced (beyond the normal ...

Re: Korg DW8000 opinions please

If the DW-8000 falls through, don't forget the DSS-1. Covers same ground yet a whole lot more, and eternally underrated. Damn right about that. 8-) Same analog filters as DW, improved 12-bit waveforms over the DW's 8-bit (had a beefier sound as a result), twin DDLs over the DW's single one, and bes...
