Hi, sorry for that, sometimes I'm to tired after this work, and I can't prepare an well planned English speech. I'll summarize for you, and I promise that I'll do more video in English. So results are: aprox 1000 w in 4R, 650 w in 8R, and 5 micro seconds Rise time in square wave. All this measurements were done with only one channel connected. Best regards.
@@patachiamihai-hyperaudio2922 Do a power test with both channels driven from 20hz to 20khz, give distortion figures at rated power as well, do 2 4 and 8 ohm tests as well as 8 ohm and 4 ohm bridge ratings.
@@analogaudiorules1724 Hi, usually all this measurements require a lot of time, and I used to test amplifiers that comes to me for repair. After I finish to repair, usually I have limmited time before I have to return it to my client. My intention is to provide generic technical results regarding to certain amplifier model, for free. And off course, if client agree on this very stressfull test for amplifier. There where some situation where amp specf contain also 2R stable, and in the first 2 second dummy load, final stage just explode, and I have to repair it for free. I'm not sponsored or something like that, but thanks for advices.
@@patachiamihai-hyperaudio2922 These amps are 2 ohm stable though, I can confirm that as not only does the spec sheet say so, but I've also used these rmx amplifiers like that with no issues.
boa noite Sr. Patachia, muito obrigado por postar seus vídeos, é muito útil. Eu queria perguntar uma coisa, pois se ajusta os controles do lim +/- (bia), muito obrigado pela sua informação é que tenho dúvidas nesse tipo de ajuste
Bună ziua! Ce părere aveți de acest amplificator merită banii? Se aude mai bine pe sateliți față de the t.amp? Mi-ați putea recomanda un amplificator sh undeva la 1500 lei să sune bine pe sateliti putere de min 500 watts 8 ohm
Salutare! Este ok acest amplficator, atat ca putere dar si ca sunet. In ceea ce priveste pretul, nu sunt la curent, pt ca nu le comercializez. Eu le repar, calibrez si testez.
Salut. Resistorii de sarcina sunt confectionati de mine, si sunt facuti sa reziste pana la 3kw. Se gasesc si in comert, dar la valori de putere suportate mai mici.
Acesta este un difuzor pe care vreau să-l conectez la amplificatorul meu vrx932lap, dar după cum vedeți, conexiunile nu sunt aceleași. Aveți vreun sfat? Cum l-ai conecta? www.loudspeakerdatabase.com/18Sound/12MB1000
Yes, we can speak english. I suppose, but I don't know what you mean... The connection is not the same like what? This is what I understand from your translation.
Vrx932 Lap, is Jbl active speaker. I suppose that the old bass speaker is broken and you wanna replace with this one. You have to take care about polarity.
What do you mean about polarity ? Well it didn’t necessarily broke. But I would like to keep the stock one out of harms way. And use the 18 sound bass from my old speaker. So what I’m asking is there a way I can make the connection (inside the cabinet with this wire reconingspeakers.com/product/jbl-364338-004-wire-harness-vrx932lap/) to the 18 sound bass which does not have the same insert as the 2262FF www.fullcompass.com/prod/138284-jbl-363946-001x-2262ff-woofer-for-vrx932lap As you can see in the pictures on the 18 sound it’s just a negative and a positive. But on the jbl speaker it’s a 4 pin connection
The vrx speaker has 4 cables going into the bass which are 2 green and 2 blue cables... do you think I should pig tail in order to make 1 positive and 1 negative. As the knowledge I see you have in your videos I would like to know if that will make my bass work with the amp on the vrx932. I got the extra cable with me. But maybe you know of a better way for it to work... I’m a bit confused cause I’m not sure from the 4 cables I mentioned, that which one is positive and which one is negative

Tried to follow you but only English or spanish. It wold have been great to see chart with end results, nice video¡

Ok, thanks for your advice. I'll try to make for future videos, a chart or a sheet with final results.

Salut, de unde fac rost/cum se numeesc resistentele folosite pt testare amplif, ce valoare au ? mercy
Salut. Resistorii de sarcina sunt confectionati de mine, si sunt facuti sa reziste pana la 3kw. Se gasesc si in comert, dar la valori de putere suportate mai mici.
Salut am un rmx 1450 si pe iesire am -0.45v dc pe mers in gol, de unde poate sa apara?
Salut. Posibil Offset decalibrat.
Salutare, in concluzie cati watti scoate la 4 ohmi si cat la 8 ohmi?
Salutare. 950 w /4 R respectiv 600 w /8R.
asta este si scopul acestor teste, fiind simplu de calculat, P= UxI, sau P= UxU/R
@@patachiamihai-hyperaudio2922 Multumesc frumos pentru raspunsul prompt. Stima.
Can the 2450 play 4 18inch subs good?
No, the output power isn't enough for 4x18 inch.
How about playing subs 15inch x 4 ?
@@antoniusriyanto1120 Hello. Yes can play 2x500w/8R 15 inch per channel.
