Half of a power amp

    Just wondering if anyone knows of any small, lightweight mono power amplifiers.

    I currently use and love my QSC PLX2402, but in reality I typically only use 1 channel (700 watts into 4 ohms).

    I know nothing about electronics nor the praticality of something like this, but could a power amp be made that was just one channel, and therefore a lot smaller in size and weight? In my wild imagination, I'd see cutting the QSC in half in both size and weight. Or is there a lot of shared ciruitry in a stereo amp?

    Perhaps Bob Lee has some thoughts on this.

    I don't know of any mono amps being used by anyone...my opinion would be...opt for the lighter/cheaper PLX1202. Bridged at 4 Ohm's it's still a whopping 1200 watts. It's good to have an amp rated at more output than your speakers as long as you're aware of it and don't crank it up too much.
    Sell your current amp, and option #2 would be opt for an even cheaper RMX series amp with even less wattage...although the RMX series are a bit heavier than your PLX.
    You'll have no problem selling that amp you currently have.

    There's a lot more demand for two-channel amps than for mono blocks. Plus, if you run a two-channel amp in bridged mono, you essentially have a mono block but with inherently more flexibility because you can split it into two channels if you need to. Bottom line: look for the two-channel configuration to be the standard for some time to come.

    So it sounds like a lower cost, lower-power amp run in bridged mono might be what you're looking for.

    Thanks for the replies. I really like the PLX2402, and don't want to give it up. If I ever need the full 2400 watts, I've got 'em, plus I can use this to power a PA if needed. The flexibility is just too good. A lower wattage

    I'm really thinking something small and light, but most amp heads with a pre weigh more than my QSC with less watts.

    Reading some of the threads on the Walter Woods has me drooling, but I don't know if I could spend that much.

    Unless the PLX specs I have are wrong, the 1202 is the same and weight as the 2402.

    The PLX 1202 is several ounces lighter than the 2402 because it has a few dozen fewer components inside, due to its lower power point. But all five models are close enough in weight that we just call them all 21 pounds.

    Thanks for the facts, Bob,

    Thanks too Joris. This is a great resource, and being in the computer biz I know a site like this isn't cheap to run. $20 a year is a small investment.

    Aren't Walter Woods amps voiced specifically for upright bass? Either way, I'd still consider it - 1,200w in an amp the size of a cigar box - that's hard to ignor.
