| | | | Plugging combo into head through XLR jack?
Sign in to disble this ad
I'm purchasing a new practice combo and it has an XLR output jack, and I was wondering if I could plug that into the input on my head and use both amps (same manufacturer) at the same time without having to buy a splitter. I don't see why it wouldn't work, but every thread in this section always has some technical wizard that proves how everything would break or how it would magically be fixed. I'm a noob with amps, it's a miracle to me that my setup works perfectly. Probably because I listened to you guys. |

The input of your other amp more probably wouldn't like it. There are other ways to use both at the same time, but without knowing your goals it's tough to say what the best way it for you.
Are you just looking to use the speaker of the combo amp? Assuming it's an ohm combo, and your other cab (that you haven't mentioned) is also 8 ohms just use the standard outputs on your head and plug into both cabs.

| | | | So it would sound more gainy and hot? Is that the only problem?
My current setup is a G&K 300 Watt Head into a discontinued Fender Pro 4X10, and the practice combo I'm getting is a Fender Bronco 40. I don't think the combo is an ohm combo.

Go from the effects send or preamp out jack of the first amp to the effects return or poweramp in jack of the second amp. The second one then becomes the slave. You only use it's master volume to contol the volume of it's speaker. The tone controls on the first amp affect both amps. |

Typically the inputs are in series to your bass signal will go to other preamp for gain, EQ, etc.
If the Bronco's auxiliary out doesn't turn the speaker off, you can either run that into the return of your effects loop of the slave amp or even use the padded input of your preamp. Auxiliary outs are typically unbalanced, as are tuner outs, so they are good for this purpose. |

Unless you're planning on using the Bronco as a personal monitor I'm not sure I see the point. 40 watts isn't going to make a 300 watt 4x10 bass amp sound that much louder. It's kind of like trying to link a Kia to a Peterbilt to use the horsepower of both. |

Unless you're highpassing the combo to run distortion effects or something, like biamping the bass rig with a guitar combo, which might be the goal here. |

Wait no, it probably turns the speakers off. |

| | | | And for the people who don't understand the purpose, I had 2 things in mind. If I could use the combo as a controller, I could use some of the effects presets which aren't in the head. Also if I could just have the signal split and use both seperately at the same time, I could use it as a monitor if necessary or Bi-amp it and make it sound different then my main amp (I'm aware it would be kinda quiet, but a subtle difference is all I need.) |

To use the preamp in the combo if one prefers it over the one in the head.
Sounds like it might not be an option with the I/O provided.
But yeah, trying to use the power/speakers aspect of it would be pointless. |
