Technics SH-AC300 Connection to Power Amp & Pre-Amp
I have a Technics Processor SH-AC300 & a Technics Power Amplifier (SE-A900s) & a Technics Stereo Control Pre-Amp (SU-C800U) & I want to connect these components together to work properly.
I have 2 Front Speakers, a centre, 2 Sourrounds & a subwoofer, so this Power Amp of mine don't have the outputs for the surrounds, sub & centres so I thought the processor would help but It doesn't seem like.

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.

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.
I assume you want to use the SU-G91 as a power amplifier to drive your speakers. If your receiver has connections for inserting an equalizer (may be labeled pre-amp output and power amp input), remove the jumpers between the pre-amp and the power amp, then run cables from the pre-amp to the SU-G91 inputs. You can have an equalizer between the receiver and the integrated amplifier. If this is not available, use the recording output (for a tape recorder on older receivers). Note that the volume control on the receiver will be bypassed with this connection.
I had the same issue.the contacts on selector switch is dirty.All u need to get a good contact cleaner and spray
the selector rod( remove knob first with preamp facing up), the liguid
will find leak into selector and clean contacts. after doing mine, the slector knob feels more solid when turned and does not change input anymore. Junior
I had the same problem with my sua900s pre-amp.
If it's the same cable, you need a (I think 6 pin) mini din cable, male to male. It's sometimes called a PS2 cable (nothing to do with Play Station!). It's the same cable that runs from your mouse into your pc and is readily available for about £5 from online computer retailers. Check the number of pins first though!!
