slave amp help me please

colindaan · #1 10-16-2010, 03:01 PM

i am trying to use my hartke 3500 as a slave amp to my sunn concert. i have ran a line from the effects send to the effects return which i believe is correct. the problem i have is i get a delay between the two rigs about 1 or 2 seconds.. why?
any help is appreciated

I await with baited breath anybodies answer as to what this might be as its the oddest thing I have ever heard.

I don't mean to offend you but given the oddity of this issue I think we need to verify your counting abilities. Are you able to provide a more scientific measure of the lag time?

RickenBoogie · #7 10-16-2010, 06:17 PM

And, exactly what is plugged into where, and with what, etc etc. Very odd indeed.

Wow.

Last time i checked, electricity flows at the speed of light..

is there an...effect pedal...in the middle of your cable?

How do the amps sound as separate units? Is there a delay in either amp? Have you tried the preamp out to power amp in? Is the delay consistent? Or intermittent? Have you tried another cable? Strange.

i have not tried preamp out to power in i thought that was a bad idea. the delay is constant. i am using 10ft instrument cord from the effects out to the effects return. i use no effects pedals. i play with a guitarist that slaves his amps out to run 2 rigs and he also gets a delay but not a long as with my rigs( seriously a 2 second pause)

Clips?

Zooberwerx · #13 10-17-2010, 01:17 PM

Is there a satellite involved?

Seriously, strike a note and....one-Mississippi, two-Mississippi...the slave amp responds?

This has to be the weirdest problem I've heard in a while. If the guitar player has a similair thing going on, could be a issue with the power in the place you're playing? Tried plugging the amps into a different circuit or move the whole thing to a different building and try it there?

Should note that the preamp out and poweramp in jacks are there to do specifically what you're trying to do.

This.

aledeville · #17 10-17-2010, 04:16 PM

I'm looking forward to the solution

MONOLITHLOUD · #18 10-18-2010, 12:42 AM

yeah the preamp out/power amp in thing should be utilized for this. plugging into the preamp out jack typically disconnects the power amp circuit or vice a versa. at any rate, you most certainly have a power issue in your space. i highly advise moving your gear to a different electrical circuit. this is truly an anomaly, i have working on and building gear for years and i have never heard of this problem.

bongomania · #19 10-18-2010, 01:03 AM

Wild hypothesis:

The mains circuit that the amps are plugged into cannot provide adequate current for both amps to achieve full power at once. Therefore the first amp (receiving the input signal first) draws all the available current for that initial note peak, and the slave amp gets no juice. As the note decays, the amount of current drawn by the first amp drops, allowing the second amp to draw current, generate power, and amplify the note. In this picture, the second amp is not playing the initial note attack 2 seconds later, but picking up where the first amp left off, two seconds into each note. The nature of the slave amp circuit may make it so there is a spike of amplitude right as it biases up to the amount of current needed to operate; and this spike might seem like a repeat of the initial note attack.

sounds like a reasonable scenario to me, change the 15 amp circuit to a 20 amp. bet the problem goes away.
