Need help on Multi Effects

[mightyboy88]

Hi guys,

I would like to know that if i have a multi eff with a stereo output and i plug it into a speaker of 20W would that be equalavent to using a 20W guitar amp ?

I currently jam at home using 2 guitars , one to an amp 15W and one to a pedal box with stereo output which goes to a computer speaker of 20W. :mrgreen:

So since my pedal is now faulty im thinking whether i should get another amp or get a multi effects plugged into that 20W speaker Thanks for reading

There are two power ratings to be concerned about. One is the power output of the pedal board and the other the power rating of the speaker.

A twenty watt guitar amp delivers twenty watts from the amplifier section to a speaker rated above twenty watts (say 30 to 50 watts) to produce sound at a set volume. The output from your pedal board will be much less than the twenty watts from the amplifier section, so will produce a much softer sound.

Not only will the sound level be lower, but you will be in danger of damaging your pedal board as the stereo OUTPUT is supposed to be an INPUT to an amplifier, which has a much greater impedance (or resistance) than your speaker has.

Unfortunately, if you want to continue using the pedal board for the guitar, you will need another amp, or run the output of the pedal board through an A/B box, with the other guitar connected to the box as well and play both guitars into the same amp.

Hope it helps.

cheers,

Mark.

Yeah thanks alot bro , it gives me a clearer picture now .

My teacher actually plugs his boss gt10 into a monitor speaker and it seems to get great sounds .

i wonder if monitor speakers r different from the normal computer speakers , mine actually has a mic in port kinda like for microphones to be plugged in to be a karaoke system . so its actually kinda like a stereo input jack i would suppose.

Would a pre mic/pre amp before the multi effects into the speaker work then ?

Monitor speakers are different from computer speakers. Monitors are un-equalized, meaning you get the true sound from your guitar/effects/instrument. A computer speaker is equalized, much like earphones.

Again, guitar effects are meant to be output into a guitar amplifer and not speakers. It should even be connected to a Direct Box before it goes into a PA System, and not directly to the PA. Doing otherwise may damage the speakers or your effects. Or both. >=S

Icic , may i know whats a direct box . is it something that changes an electric guitar signal into a sound signal ? And where to find these ?

 

[PatheinRaindropMoe]

here, DI box

 

[mightyboy88]

Haha yeah appreciate that

Well i get this would be what i would do ,

Guitar-to-multi-effects-to-DI box-to-speaker

Putting performance wise aside would it be safe to all the components ?
My DI box comes in the form of a Behringer mic100, which is a tube premic, it gets quite hot after being used for some time ? Is this normal for all tube premics and would it be better to use a simple passive DI box for the above application ?

 

[PatheinRaindropMoe]

after di box, usually to mixer/audio interface then to PA/monitor.

its vacumn tube, so there you go. At least you know that the tubes are working hard for the sound

anyway, active or passive di, just get one and try out. It aint too expensive as well. Especially if getting the behringer one.

DI's are nominally used to drop the amp signal down to use in a recording desk is different from the mic preamps, which increase the power of the signal of a microphone so that it is strong enough for the recording desk. DI's tend to be passive and preamps active.

In the case of your multi effects, the safer option to operate it into an amp (I have done this before), is to lower the output volume on the effect unit and run this into the amp with the volume set low. Run your signal into the low impedance input (normally the left if there is no marking) and the amp will think the effect signal is from an active pickup guitar.

cheers.

These mic preamps are used for condenser mics (the more expensive ones) and not normal mics like a Shure SM57.
