Question about Amplifiers & Preamps

1 Answer

Home amplifier I have a technical pro home amplifier i'm getting a humming noise from it? I have it connected to a surge protecter/filter and also have 30.5m high density speaker wire. And i still get the light hum from it! This amp is a intergrated power amp. It has a cooling fan on the back that pulls the heat out i'm wondering if that is were the noise is comeing from? The rated output power is channel A:1KHz.8? i dont know if the symbol after the 8 means ohms.And channel B is the same. would that be the problem if my speakers only have 4 ohms.

    I just bought the same amp and have the exact same hum, no matter what.  No response from their support staff yet, I'm definitely open to all suggestions.

    When I turn on the Krell Showcase 5.1 amplifier there is a spark like pop followed by a hum. It works and the music can be ehard if loud enough so the hum can not be heard.

    Any ideas?

    Thanks

Hum is probably due to insufficent grounding somewhere. Make sure coax cables at input are good. Re-locate unit away from aplliances

Connect a TV to a Tehnical Pro AMP 1100


Depends if your TV has audio outputs. If not use the Headphone Out, just get an adapter cable from that to the amp.
Luck.

Fault lights on


It is possible that the amplifier had encountered a fault with a higher current drain which had triggered it to a protection fault condition. The fault can be with your output drivers. Please check for short on the outputs fitted for both the channels. Use a meter after disconnecting to check for short in the drivers. Disconnect the positive and negative voltages to the output and see if the protect changes. Even a fault in the preamp stages that drives in high current into the output can shut the Amplifier. Sometimes this can be a noise which can be a HUM or HISS before the protect works. Faulty capacitors in these circuits also can cause similar issues and needs close observation.You need to confirm and replace the specific stages or outputs. If not there can be issues in the mother board. Maybe the protect circuit by itself is shutting off due to a faulty bias or there is a leak in any voltage/current sensing circuit. Also disconnect the speakers and test, if the amplifier comes out of the protect mode then check for short on the speakers.

My su-g95 technics Stereo integrated amplifier wont play any noise. and when i adjust the volume it makes a popping/crackling noise. i am 100% sure all the speakers were hooked up correctly.


Well it sounds like your amplifier IC's are working correctly since you are hearing that pop. I have the same amplifier and every 10db increment it pops. Have you tried every input? Possibly try starting at a low volume, plug an RCA plug into CD or any other input, and touch the center prong of the other end of the cable. You should get a 60hz hum if your in the USA, otherwise it will be 50-55hz. Regardless it should make noise.

Hi, I have an HB3502U Technical Pro Hybrid Amplifier/Receiver but no matter how I connect it there is aloud Humming noise. Can you help?


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!

What amplifier is this? Humming noise is normally caused by video cables in audio ports, high voltage wires too close to audio wires, or ground loops.

Re: Technics HD51 home stereo system (amp, tuner, CD, and cassette player) - I'm told it needs a pre-amp in order to get any reasonable amount of sound out of lp's on the Linn Sonex LP12 turntable. At the...


The Amplifier must have a high impedance input for the turntable to be connected. Now most of the present day amplifiers do not have this input but only the regular aux input which is designed for a larger signal . But the turntable outputs is quite low and so it requires an amplification of high order. What you can do if you need to play the turntable is to have first a preamplifier with a high impedance which is available even inkit form and can be fitted on to your system. The preamp output can be shared into the input of the source selector maybe with a switch and you willl be able to fix two RCA sockets to accept the input of the phono. This will work fine provided the shielding is done well to avoid the high feedbacck to oascillate and cause noise, the premap must be housed in a shielded cabin. On the other hand you may have to buy a universal amplifier so that the phono input is present. Definetely nothing better than a designed input. So think and decide. hope I could help; Good day

I get a constant noise after I plug in the guitar


The reason for the few seconds delay is that this amp uses a vacuum tube preamp which has to heat up before it operates.
Now with most amps at high gain you will get some noise, but it should be well below the level when you are running program material through it. The statistical electronic noise will be more of a hiss. If it is hum you are getting, then the filter caps MAY have failed. Also if you have light dimmers can sometimes get into the equipment.
First step is describing the type of noise. Behringer is VERY stingy on supplying schematics. Essentially they WON'T unless you are one of theior certified techs.
Your amp SHOULD be simple enough to fix without schematics UNLESS it has one of the Behringer digital effects. That board has a chronic failure of the DC filter cap.
