if its not stereo, then why 2x60, why not 1x120?

..or is it 2x60 because there will be two guitars plugged into it?

I use "stereo" guitar amps, simply because even the small spacing between the speakers improves the sound when I'm using time-based effects such as stereo chorus, echo and so on.

And the spacing between the amp's speakers can be as wide as the entire sound stage when playing live, with each speaker miked separately and fed to the FOH PA.

What a pointless thread. It's an instrument amp, and the primary reason for choosing it is if it sounds they way you want it to with your guitar(s) and effects, not technical specifications. Everything else is secondary and can be dealt with in other, better ways.

pinkmouse i agree with you.

...thing is, when gigging in fields using a remote generator, you need to limit power consumption, so its nice to know the maximum power draw of the amplifier......as otherwise , we run out of power half way through the show, and out come the acoustic guitars.

I dont understand
why would a power generator run out of power half way through
either it works, or it doesnt, I guess

but I know as little as you do

Its one of those small electric generators which runs on petrol.

When the petrol runs out...thats it,....no more electricity.

The maximum power draw will have little to do with how long the petrol will last because your consumption will vary widely depending on how loud you play. Idle consumption is probably less than 20 watts but full blast thrashing could take you near 200 watts. YMMV

200 Watts......?

Are you thereby implying that this amplifier is very inefficient?

...because the maximum power of the highest power ID series product is 2x60W = 120W.

...I am guessing that you are saying that the extra 80 Watts is lost in circuit inefficiencies?

One 60W linear class AB power amp will consume about 90W when delivering a 60W sine wave into a resistive load. A class D power amp will be closer to 60W. The same class AB 60W power amp will consume about 120W when it is delivering a rail to rail square wave into a resistive load. The advertising copy from the manufacturer does not give any details about what circuitry they are employing. I assume they are using a couple of chip power amps like the LM3886.

A conventional power supply with no Power Factor correction is only about 50% effecient when comparing Watts delivered divided by VoltAmps consumed from the power line. A switchmode supply with PF correction will be around 90% effecient. Again, the manufacturer does not give us any clues however, some countries in Europe have restrictions on what kind of power supply is allowed. Ask the manufacturer about the amp's power consumption.

might be an interesting amp
digital effect stuff can be great fun
but also a bit tedious in practical use
and can harm your ears badly
but whatever
I was put off from early on, when they write...True Valve Power
what kind of crap is that
