Question about Technical Pro TA-4250 Amplifier

Open Question

I just bought Technical Pro TA 4250 amp, like 2 days use, had my music down to like 8% volume and i paused my music, came back and unpaused it heard this loud pop n grumble sound coming from my CV JE-36C sub, after a little smelled like something fried. a friend told me it was probably a fuse and I cant even find where the fuses are on this amp. Is this a blown fuse or what? and if so where are the fuses or redirect me to a manual cuz it didn't come with one. Bought brand new str8 from NYC, made sure none of the levels are maxed or anything, when I turn the amp on the blue LED lights up but it shows no detection that music is playing from the sub and the humming noise the sub usually puts out when it is connected to the amp is no longer heard FYI. Its being bridged on ground setting and I have RCA's connected to my bass slot on my sound card, just throwing that out there in case that helps.

The most obvious cause is the failure of the large Electrolytic Capacitor(s) in the main power supply section. These take out the 50/60Hz hum in the mains supply, which is what that noise is!

12" woofer not working


I bought a 3rd B212D unit that powers on, has white noise, no music. I took the 8 screws off and discovered that the solder connection at the woofer had broken off. I surmise that either the unit was dropped or the speaker wire had gotten hot over the years. Since the amp had an open output from the break, the high output burned up as I heard a pop when I turned the volume up. . If your volume wasn't maxed out, you could check the wiring and make sure it is connected & save yourself some change!!!

I have a sony ta-fe370 amplifier. I bought it 5 years ago. 4 years ago it stopped working. I would now like to repair it. The problem is that it turns on and the power light comes on and so does the...


The problem is hard to track down, but fixable. You need to determine if the pre-amp has failed or the power amp. To determine which try this: Connect a device which plays music and turn the volume control fully up! You can sometimes hear the sound better via a pair of headphones. If you can hear any signal or music breaking through, then the pre-amp section is OK. If you can't it might not be. If you can hear faint music then it will be the main power amp to blame. Now because you have lost both channels you must only investigate devices (such as IC's) which have both channels running to them. Some amps have one big power amp IC that does the work. So if that goes it takes the sound with it. Have a look at whatever is on the big heat sink first, that will determine a lot of your future actions.

Can you connect subwolfer as well as speakers with this amp


Well, PASSIVE subwoofers ARE speakers. And this IS an amp. You could use it for a subwoofer (bridged) or two. It would also support a sub on one channel and a different speaker on the other. It's your choice what you want to drive with it.

I'd take that 4250 watts claim with a HUGE grain of salt as no distortion or bandwidth spec is included with it. If the lights in your neighborhood don't dim when you turn it on it's pulling WAY less than 4250 watts.

Crackling Audio


Is there any other programs running in the background IE Anti-Virus programs, or anything that could be using quite alot of Memory other the stuff your watching?
It could be either down to Lack of Memory being allocated to the Audio & Video (Probably the case if the machine has built in Shared Sound & Video Card). Try opening Task Manager and setting the Application that you use to play Music/Movies to High Priority.
If it's not that try lowering the Master Volume on the Mixer Device by going into the Volume Properties in the Task Tray (By the Clock).
