This is a Class D amplifier, yes? I hope you know how to bench this type of amplifier and document your process appropriately before you post utterly pointless results that might put other people off using them.

The K 30 arrived today. I powered it up just to make sure both channels pass signal on 120 volts.



Now, I need to buy a 120-volt receptacle to attach to the Hubbellock 600 volt plug. As this amplifier will be receiving 250-volt line voltage, I do not want to use the standard 120-volt receptacle (Offered on the amplifier) as that is against our electrical code.



Since the Hubblelock is only found in the industrial market, it eliminates any Non-Hubbellock home consumer plug inserted into the Hubbellock receptacle distributing 250-volts. The K 30 offers a maximum input line voltage rating of 270 volts. This is ideal as the amplifier should have no issues handling 250 – 256 line voltage.


You should see the bench test results of the K30 posted in the Amp Forum by the end of next week.


Best Regards,

I just ordered the K30 Amplifier.

I bought it solely for low mids. However, once it arrives, I will put it on the bench and, post the measured wattage using a sinusoidal wave ranging from 100 Hz - 5 Hz. Once it arrives of course!

Best Regards,

today I did a quote for a sound system, which involved trying to remember what I would need to make a live gig happen. God its been a long time! Next challenge, how do you mix a band again?

Picked up an Behringer DX 1000 for a very low price to use as Traktor's primary mixer. The other mixers I have lying around offer a gradual roll-off @ 20 kHz which, can be heard in the Tweeters once, inserted in the chain, within the 12 kHz on up range.


The graph below shows the roll-off curvature does not come into play until 60 kHz which, far exceeds the standard 96 kHz sample rate I use for Traktor.



On the low end of the spectrum, the -3dB point is 6 Hz . This is common with most older Analogue DJ Mixers on the market.



If the sound of the DX 1000 is not noticeable once inserted in the chain, I will buy a case for it. If it is noticeable, it will be used for Samplitude. Either way, the price was too low to pass up.



Best Regards,

Nikola is definitely not the fault here.

Picked up an 0 – 250 A.C. Milli-volt Meter in addition to, a 100 Milli-volt to 200 volt A.C. Meter

These units will allow me to monitor voltage leakage between the Neutral & Ground. At the moment, the Analogue meter registers 50 Milli-volts from 124-volts to 128-volts per leg.

Yes - it would cost far too much to change the system now. Blame Mr. Tesla!!   Smile

That, thankfully has now changed and everyone has a proper 230v supply these days. But, I guess that would be far to expensive & complicated to do now in the US!!  LOL





Considering the majority of household appliances operate solely on 120 volts, I would imagine it is cheaper to keep the infrastructure as is and, repair any issues than, upgrade the whole electrical system.

We did our first "proper" gig exactly a year to the day after doing the same festival on the day before lockdown last year.... Super happy to be out setting up again and to top it off we had Public Opinion Afro Orch on the stage who were amazing....



Even the torrential rain couldn't dampen the crowd or bands... Top day..

.p.
Mostly harmless.... except if catering is shut.

It offers an Isolation Transformer so, it is still useful to reduce ground loops which, is very common in the States.
