Phoenix Gold Phorum

I am trying to look at the specs and stuff m44,m25,m100
I tried going to
http://www.phoenixgold.com/downloadpg.html'
And clicking on Manuals
I get a error message "Windows cannont access the server"!
So what is the problem? Wll it be fixed soon?

Main questions are

Is the old M series, the ones above able to take high input Volts at RCA level?
Are the RCa inputs balanced because I am concerned about ground noise.
And can the crossovers be totally turned off if I have a head unit with crossovers?

I am thinking about getting an M100 and 2 M25's. Use that with a Cyclone and RSd comp's.
Thanks

Here are some specs of the M series amps.

I would recommend a line driver if using any of the M amps.

Not sure on question 2, but they do not have a balanced line input on the amps, only the typical RCA input.

You can bypass (push button) the xover on the M100. M25's do not have a xover.

Thanks.
Have you or anyone else had ground noise problems with these amps?
I can really dont want the big trouble of that at all. Id rather just get balanced inputs if I will have trouble.
I had an Xtant setup that had a switch. On or off for balanced. Why cant other amps do that? It made a HUGE difference.

I never had one issue with my M amps in the 11 + years. No ground noise whatsoever. I ran a PLD 1 with them.

i was told by onemoreamp not to run more than 2v input to these m series amps as it can burn the inputs. he told me to use a line driver to reduce the 4v preouts on my h.u.

i know some guys here have not had a problem with running more than 2v input but i personaly dont want to chance it on my route 66 or outlaw.
besides if the amps are only setup to run on 2v inputs i really dont se what gain you would get from runnig more..........

if you're gonna buy - get him to take some pic's of the inside first - here's why : http://phoenixphorum.com/capacitors-ins ... t2477.html - oh-manuals on their way

empty your mailbox please - can't mail 'em 'cause it's full

Ok its probably cause email doesnt let you send or me recieve anything bigger than like 3 or 5 MB's. I have no emails in my box.

only m25 got through - rest is too big

Nick, don't worry the manual site is ALWAYS on again, off again. It'll be back up soon.

Hi Guys,
YES you can clip a amp with a LD if it was not meant to be used with one, and this is something to be careful about. I have Ryan's M-100 in front of me, and it had a LD on it when he was tuning his bass and it has become damaged by the excessive drive capable from a LD.

LD's have a purpose and a way to use them without risking damage to your old school amps like the M series.

In my mind <ok no jokes now> I would use a LD and then feed its output to a resistor network to voltage divide it back down to a normal level at the amp, minus the noise floor issues of course.

LD's serve several purposes,

1: To increase signal level from a HU that does not have proper level outs to drive your amp system with. ( Many HU makes lie and have pitiful output levels)
2. To reduce noise floor issues, by making you reduce your input gains to zero or minimum gain settings. < the norm as I know it>

I will post more later as i am at the shop and have top get some work done
