[Why 40 hz? What about the other frequencies?]

FYI: the output needles on a RF amp are not set to turn red at clipping. They are just output LED's that's all.

OH, I didnt know that....tought they were accurate

Guess Im going to coff the U$150 and get a DD1

Meade, do you guys plan to sell the used DD1s that comes from the exchanging to DD+1s?

[Why 40 hz? What about the other frequencies?]

I guess I understand now!!!

But then there is one problem: I cant play any music ?

I mean, If my friend comes over with his pendrive and the music he wants to show me is at 0 db , if I set my gains at -5 db, i will be clipping at my maximum volume?

That looks complicated....it means I can never be 100% safe

[Why 40 hz? What about the other frequencies?]

Hey guys,

I was talking to a friend of mine about the DD1 the other day, we stumbled upon the fact that it only measures distortion at 40 Hz, based on the following fact:

I have a RF T2500 bdcp amplifier which does come with a output meter, so I tought I could trust it to , at least, know if im near clipping

I used a 40 Hz test tone to set the thing by ear and eye (using the output needle), ok, it sounded preety loud at that frequency and didnt look distorted, so I was happy for that day, went to bed and slept

The following day, I was at a lower volume , 15 (I've set my gains with a volume of 25) listening to some low bass music (woofer cooker, decaf, etc) and I noticed the bass was extremely intense, took a look at the output needle and it was ONLY red (maximum output)

I was very confused, if I used the same principle as the DD-1 it should make that much difference between the frequencies....I was probably very near clippling at volume 15 while Ive set my gains at 25......if I did the same with the DD1, the same thing would have hapenned

Am I right or the RFs output needle cant be trusted?

So....why 40 Hz at setting gains with the DD1, and does that really work? I mean, couldnt I have a clean signal at 40 Hz and a clipped signal at 28 ?

Thanks

Just to let you guys know

I fould out it as a scam.....didnt even contacted the guy back, but after some research I found out he usually is not honest, so I just gave up

Hey guys! Good news, I think

The guy sent me more pictures, he said 2 are like the one I originally showed to you , and 2 are like the newer model I found on the internet, he sent me these pictures:

These are the 2 newer ones, he said they all are were bought this year, but the first two (older models) were bought on a first trip to the USA he made, and the another two were bought on a second trip, around 20 days after the first one

He also sad he has the receipt (thus warranty) for all 4 batteries

The resting voltage should be around....?

[Is this battery authentic?]

I think they all have that hole, yes

So its an older model?

I can see that there is also no handle for transportation, while the new ones have....correct?

They are really, really, really cheap

A new one in my country is around 600 bucks, the guy is selling them for something like 80

Hey guys

There is a guy selling FOUR D3100 XS Power in my city for an UNBELIVEABLE price

He sent me these pics:

Im asking because im about to buy them, and Ive heard there are some fake chinese XS Power batteries....can anyone identify if this one is original or even if theres a way to tell?

As far as I can see, these are different from the D3100s Ive looked over on the internet..so they may be fake

Thanks
