Re: Got a m50 yesterday
Clean amp for sure. I'll own more of these someday

Re: ZPA 0.3 and 0.5 output testing
I adjusted both channels to slightly under clipping for measurements. In an installation I would adjust each channel the same output and tune from there. Both channels are probably identical in output given the exact same load. In my testing equipment there is a high margin of error and the resistor...

Re: ZPA 0.3 and 0.5 output testing
While it may be slightly different with sine waves I highly doubt you'll be able to hear any difference in balance with music and a few watts. Also did you try matching them with the gains once your feeding the sine wave? Or does it chance/vary with time/heat. I gain set the gains to at slightly un...

49 views and no replies. There will be no point in me posting further testing on this forum

Re: ZPA 0.3 and 0.5 output testing
I also plan on testing this with a pink noise signal versus a sine wave. I have a feeling that the amperage draw on a 1khz sine wave will be higher than that on music.

ZPA 0.3 and 0.5 output testing
I did more testing with the ZPA's. The two that I tested are a v1 0.3 and 0.5. Both have had v2 upgrades and capacitor replacement. Both channels (one amplifier at a time) are measured at the same time (with only one channel driven output is higher, which would give a false two channel output test) ...

Re: ZPA balanced input configuration
Got it. I pm'd him. I doubt the ALD will work. On the hunt for two TBAT or TBAT2 it will work and has been done. ive done it back in the days with a couple different brands of balanced line drivers before i found new tba's to run with my zpas, orion,denon,soundstream,RF,adcom, etc make balanced dri...

Re: ZPA balanced input configuration
I did contact Valek and he said I need to make a custom cable. I will probably see if he will do that when I send Altser the amps for upgrades. Unless I can find two Tbat2!!! The ZPA 0.3 is going to power my Eric Stevens Ultra horns. They are 8 ohm drivers and require very very little power to get l...

Re: ZPA balanced input configuration
ya know its a neat option and all but with all things being taken into account I am not sure many of us would be able to A-B a standard/balanced system and guess them right. In the end you will have another piece in the dash to hide and power, a cable that doesn't look much different(other then pri...

Re: ZPA balanced input configuration
Ok, I believe I have found the layout for the RJ45 connector at the amp
Do you think the Arc Audio ALD will work with the ZPA's?

Re: ZPA balanced input configuration
I will also add that the ALD is a two channel balance line driver.
Here are the dedicated pin locations for two channels.

ZPA balanced input configuration
I would like to use an Arc Audio ALD (balanced line driver) for my ZPA 0.3 and 0.5
Is this the correct pin locations on the CAT5 cable for the RJ45 input on the ZPA's?
This is from the Arc Audio ALD website :
