A floating safety ground can measure tens of volts WRT neutral or line, when using a high impedance VOM. This stray voltage is low current and generally not a shock hazard by itself, but the lack of a true safety ground connection leaves three wire gear unprotected. JR

Lead guitar amps add their own characteristic sound that would be lost from a DI. If you have extra channels maybe try both and see for yourself. JR

perhaps AI or human machinations to establish multiple forum accounts for later use spamming. Or not. JR

besides the power (heat dissipation) constraints, passive loudspeaker crossovers must survive a high vibration environment with occasional drops. Even thru hole components often get extra mechanical stress relief. JR

Digital pots deliver good audio performance and use CMOS transfer gate switch technology inside. They will generally not handle 24V DC or 70V audio. JR

If the Behringer automix is using the Dugan algorithm (which it probably does) there will only be one AM output since it mathematically compares the level of the final sum to all the stems sending to it, that proportions the gain of each stem based on that. That final AM can be sent to different...

We lost another brilliant audio engineer. While few knew who Jack was, millions have benefitted from his product designs while director of analog engineering at Peavey for a few decades. Perhaps his most iconic product is the CS800 with over half a million sold and probably the majority of them...

Wow, wrong on a few levels. The low price X-32 is certainly an achievement but not revolutionary. Ford was a true visionary about advancing manufacturing technology (assembly line) and even for paying his workers more (so workers could afford to buy a car). While the later Apple products were...

I have been predicting the the end of consoles entirely, with their functionality moving into different functional blocks that can't go away (speakers, mics, etc). I think we are in a early evolutionary stage away from the old school physical integrated console/control surface. With all...

NYC was built on low ground between Hudson and East (and Harlem and Bronx) rivers. The freak couple hundred years storm caused the record storm surge. Climate experts warn against reading too much into one or two storms but there are changes in weather (high pressure) patterns being blamed...

No not politicians, they lie for a living :-(. I just read an article where consumer market research firms are trying to get more honest answers from consumers. I have observed this disconnect for a long time. Look at what consumers actually buy, not what they tell you they would buy...

I always credited those old TV commercials for children's toys that never lived up to the imagery for teaching us to be skeptical, but lately I've been picking up on commercials that are just nuts, if you pay attention to the context or details. One recently selling a water bottle with filter...

LoopSlooth - Find ground loops fast and without disconnecting anything only $1250 for the small one... I don't know how we ever got along without one of these... ? JR
