Tell me!!! How does the PK1 sound with PA2V2?


NAOOOO!

Hmm, maybe I should pick up one of these.

I remember hunting for a new amp, and the only reason I backed off buying it was to buy a 2nd hand Corda XXS.

I am looking PA2V2s on ebay right now.

I really hope I get one. lol

I opened my pa2v2, saw the 2 knobs. However, can you or someone else, indicate me if it really does remove hissing, and which one does what, cause there is 2 of them.

If I want to 1) remove hissing and 2) lower the overall volume, as I have really sensitive headphones, what should I do?

Rotate the screw clockwise or counter-clockwise? And which one?

My batteries, connections, sources are fine, by the way...

I don't want to send my amp back to Gary just to modify such a small thing, and I'd really like to stop using a volume attenuator with it.

I know many people here have experience with the pa2v2, but I don't see any thread, anywhere, talking about the subject. I also don't want to break my amp...

Thanks in advance.

Both the blue knobs are used to adjust the gain level for the headphone. One for left driver, the other for right. What you can do is plug the PA2V2 to a source (don't play anything) and adjust the gain level until you hear no audible hiss at higher volumes, this way, you don't risk blowing your sensitive headphones.

As you adjust the gain level to remove hissing, the overall volume of the amp should be lowered too. Just to remind you, there will always be some audible hiss, depending on your source, or the recording.

Thanks for the info. I will probably have some time to play with it in the weekend.

I'm very surprised I never heard anything on gain adjustment on the pa2v2 before. I guess the adjustments are the same with many portable amplifiers too. Maybe I just usually rarely hang in these forums, only about a week before and after an important purchase...
...I should probably visit the forums more often.

Thanks again for the answer.

I was gonna take a walk, but instead, I first listened to my pa2v2, without touching anything, and was amazed to find out the sound was extremely grainy, «AM radio style», and the right channel was completely gone.

Thankfully, it wasn't the amp, but the extremely flimsy 4 inch interconnect that came with my E5.

Then I opened it, took my trusty screwdriver, attempted to move the two big "knobs" (just over the IN and OUT of the amp, that look like AAA batteries from the outside, and from the inside, has a small black screw-like side that fits a very small flathead screwdriver). But nothing happened, to the left or to the right. Doesn't seem that sensitive. I don't want to ruin my amp either. Maybe mine are just fixed...

I don't see any other "knobs" in the amp, so mine maybe just doesn't have any kind of gain setting adjustment.

What does the "knobs" look like anyway?

By the way, it's saturday night, if you are reading my post tonight, have a drink on me!

There you go!

Cheers!

Wait, so your right channel started working again? That happens to me from time to time (right channel falling out), but only because the miniplug isn't entirely into the output. Inside of the amp there should be 2 small blue plastic screws. They control the gain. However, if you have an older amp, not sure how old, the gain screws aren't included.

Thanks for the input! Seems like the plug wasn't entirely in the jack, as you said

The cable is still cheap, but perfectly fine!

My amp is from august 2006. Very young, but I guess it was made before that slight change was made.

I know some sellers here probably could hate me for that, but people should be advised that the new ones have gain adjustments. People should be aware that newer ones have that small option available. It's a nice touch, and if I were to buy a pa2v2, I would like to play with those.

By the way, it is a very fun and energetic, very aggressive amp.

Not so smooth, not so musical, yet fun. I don't like the word, but yes, it is most definitely colored. I like it. I would have liked a little less hissing, and more volume control with my headphones though.

Thanks for the input!

Here's one for you to!

Good night!

Darts! I'm working tonight.

but hey, cheers!

The two gain knobs I mentioned earlier are located near the battery enclosure. Its paired up closely together, and they're blue. Have fun tweaking.

It was never mentioned in the website, Gary told me himself via email.

Pleased to be able to help. The cable won't have an impact at this stage in the game

. I got my PA2V2 just this last Christmas, and Gary mentioned it in his communique. I don't totally know how to use the screws, so I haven't messed around with them.
With hissing, a lot of the time it is due to using Alkaline AA batteries instead of the slightly lower voltage rechargable NiMH's which the amp was made for. I use non-rechargable 'ultradigital' batteries, and those do the trick.
