SOURCE: Technics SH-AC300 Connection to Power Amp & Pre-Amp

Hi!
The problem is, that your SH-AC300 needs an amp with 5.1 input (but no decoder). For this purpose technics delivered SA-AX710.
So if you'd like to use your current equipment it would be impossible.
The only option is for you to buy 2 more Power Amps (SE-A900S), so that each of 3 amps would take care for one part of music. (one for FL, FR; one for RL, RR; and one for sub and center).
Another option is for you to buy SA-AX710. Then all the problems would be solved with it.

Ok, i interested in the technics se a900s amplifier, just for vu meter use, not amplifier,and...


Pre-amp only needed for phono. Otherwise, line in is just fine.

10 to 20 ohm load resisters to substitute for speakers. get 50 watt rated ones at least, they can get hot....

I will buy a Technics se a900s amplifier, but


I think you are saying you want to connect the amp and use it's vu meters but not connect it to speakers?
Presumably you are already well catered for in the matter of amplification but lacking good vu meters?

There is a fair amount of information about this premium amp online including operating and service manuals that can provide a better answer than I can.

One note of caution; it is generally bad practice to operate a power amplifier without a load at the output and it might damage the amplifier. If it is desired to operate it without speakers providing the load, dummy loads are available.

I suggest you have a look through ebay or Amazon where you might find digital or analogue vu meters at a reasonable cost or alternatively I believe computer software could turn your laptop into vu meters.

Greetings. I'm thinking of buying a Technics SE- A 900 power amp but the lights don't work. Does any body know where I can fix and approx how much. Many thanks


Personally I wouldn't buy it. A power failure could indicate a serious problem. Most amp power failures are caused by power transistor failures. Sometimes these transistors can cost a lot of money if they are not common type. I once had a amp where one transitor would cost £50 to replace, and it need 3 of them!

I HAVE A BSR 3000 EQ, A TECHNICS POWER AMP SE-9021K,AND A TECHNICS SU-9011K PRE AMP HOW DO I HOOK IT ALL UP?


Very easy.

SOURCE > PRE-AMP > EQUALIZER > POWER AMP.

Not sure why you want to do it, though. Your pre-amp already has an abundance of sophisticated tone controls and filters.

If I might venture a guess, you are trying to correct some serious deficit in your speakers or in your source. If you need sophisticated tone controls, filters, AND an equalizer, you need to ask yourself why ... and fix that problem.

Technics SE-A 2000. Powers up but current protection switch cuts in and shuts amp down. this occurrs whether speakers are connected or not.


It is not so easy to probe into to find a protection fault condition. The fault can be your output drivers- the mosfets 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.
If so replace the 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 , maybe a leak in any voltage/current sensing circuit.Also disconnect the speakers and test, if the protect is off then check for short on the speakers.

Technics Tape Deck RS-M227X. VU needles jump to the maximum right


More than likely the pre-amp IC has failed! Trace the wires from the VU meters back they should locate the source of the problem. Remember it will be something common to both channels!

Vestax pmc07 pro powers up, but no output through amp or phones????


most likely one or some of the op-amps are blown. you are using the right ac adaptor too? sometimes when underpowered it will give a low output. also are you getting a read out on the vu meters? if so then most likely the op amps. if there is no read out on the vu meters, it could be the input stage. have you also tried your mic and aux in too?
my suggestion is, that if its under warranty get it fixed.

Replacement parts for Pyle power amp PT-2000


VU meters are generally illuminated by small bulbs at the back of them. It's unlikely to be a powerfull bulb perhaps 12 volts perhaps around 200ma at the most. Most electrical shops should sell something that should suffice. It could be an LED though!
