Hi there,
I was wondering if anyone had trouble with excessive noise from their Ghost Power Supply ? Mine is 5 years old now and it's started making strange sounds ...a bit like wind whistling through an alley ..but far away umm? ... It's quite disturbing when you live on the moors :?

:( DAvid with LoVE.

What's up?

I just picked up a Lectrosonics PA-8 8-Ch Power Amp for peanuts on eBay. It is a 6w x8 @ 8Ohm, or 10w x8 @ 4Ohms power amp of very high quality. http://www.lectrosonics.com/lecnet/pa8.htm (Retail over $1300)

I'm trying to figure out how to wire my Neumann KM56 to a Neumann N52a power supply. I'd like to know which pins on the 6 pin tuchel connector at the mic go to which pins on the rectangular 12 pin tuchel connector (1a to 6a & 1b to 6b) on the N52a. I'm aware that 220vac goes to 6a and 6b but I'm unsure of the rest.

say i have a solid state mic preamp like a trident, or Neve or something like that and a solid state power amp like a QSC rmx2450. or even for the preamp use of a 610. would that be acceptable and yeild good results for use as a guitar head before a cabinet.

Sennheiser say that an e865 will live with 12 - 48v phantom power. Will this microphone perform differently when using e.g. 15v instead of 48v? Will performance degrade on a lower voltage?

I have one of those older analog Hill Multimix mixers, 16x4, with the external power supply (PS1)... But I don't have the power cord..
I do have connectors that I can use and this is where the stupid part comes in.

On the back of the power supply it shows which pin is what. ie: the voltages for each pin, 1 through 5.

Im thinking of gettin a pair of AA151and a pair of AA15HL both 400watts at 8 ohms for FOH and a pair of JBLPro JRX112m 250watts at 8ohms for monitors. what power amps do i need to be looking at?

Hi., I now got my Soundcraft Ghost 24 with mute automation. I think it was a pretty good deal at £750 ($1,200 US). BUT, it came with the old green power supply (PSM 300). After spending hours reading about ghost modifications, virtually everyone says that a better power supply will improve the sound and performance.

What is the performance of MC2 audio 1250 power amp compare with chord SPA 1424 - Mono and FM acoustics FM 811 MKII power amp?

Is it suitable for mastering studio ?

I thought it might be a good topic to discuss amps.

I know a lot of guys use Bryston, Rotel and McIntosh. But what else is out there? What are the advantages of different brands in comparison to the others? What are studios like Sterling Sound using?

Go into detail on your opinions on power amplifiers, if you would.
