Here's what one of my rack mounted pre-amp rigs would basically consist of.

Rack case, A line conditioner, tube pre-amp, couple stereo equalizers, tube power amp, attenuator, speakers. From the attenuator outs both line and speaker outs I run into other eq, power amp, setups. Please note that running other equipment from off the attenuator speaker outs you need to monitor the signal levels to stay within spec's. +4 to -10. If you don't you damage things real quick. However the preamp rigs tube power amps do drive speakers also. Which will be loud enough for most playing situations.

Essentially what I'm doing is amplifying my sound and tone which I achieve from the pre-amp setup. Different guitar amps whether its a 12 watt tube amp or Tube stack is also running at their output saturation point, then from there if more volume is needed I use solid state power amps and 4x12 cabinets or the speakers from the pre-amp rigs are miked or line outs into the main board. Hope this helped answer your question.

any other comments?

Colin Total control of what sound? The power amp will (lightly) amplify and produce a high power signal appropriate for driving a cab. But all the character of your signal will now depend upon creating the tone (and most of the gain) you desire in a preamp and effects processors or an amp modeller (e.g. POD XT) or maybe a preamp, FX and small saturated power amp to drive the big power amp. With only the Alesis power amp and cab, you are essentially creating a line-level input PA for a guitar -- the only sonic character from these components alone with be that imparted by the cab/drivers. BTW, this amp should not be driven to distortion (overdrive or saturation) in any way or your cab drivers are toast.

I'm sure Joe forrock_star will weigh in on this, as he does use smaller tube amps and attenuators and EQs and some other items to produce a signal that drives a higher power amplifier/cab.]]> Live Sound gnease https://guitarnoise.forum/live-sound/power-as-amp/#post-81028 https://guitarnoise.forum/live-sound/power-as-amp/#post-81023 Wed, 22 Dec 2004 23:21:34 +0000 Live Sound greybeard https://guitarnoise.forum/live-sound/power-as-amp/#post-81023 https://guitarnoise.forum/live-sound/power-as-amp/#post-81001 Wed, 22 Dec 2004 20:42:30 +0000

and just hook it up to the cab?, get a pre amp, and an equalizer, or something, ...would that work?? as of now i have a marshall avt cab, 200W @ 8 ohms, i am just wondering if this kind of thing is done, im really unhappy with ALL of the amps out there ive tried, and looking for a way around it, and keep it in the rack, any comments appreciated thanks.
