Billy Apple Posted January 14, 2014 Share Posted January 14, 2014 All in the title really. What is Bi-Amping? How does one Bi-Amp? Quote Link to comment Share on other sites More sharing options...
discreet Posted January 14, 2014 Share Posted January 14, 2014 (edited) Very basically it's using one amp to handle low frequencies and another to handle high frequencies in conjunction with a crossover. ...I think. You can also tri-amp and have another amp doing the mids, too. At least in the world of hi-fi, you can. Edit: I expect someone who knows what they're talking about will be along to explain it properly, soon.

Bill Fitzmaurice Posted January 14, 2014 Share Posted January 14, 2014 You use one amp for lows, one for highs, with an electonic crossover splitting the signal before it goes to the amps. Some electric bass heads have an electonic crossover and dual amps. It's used all the time with PA. For that matter it's used in home hi-fi/HT; an x.1 AVR and powered sub is a bi-amped system. It's seldom used with electric bass, other than to sometimes separately power woofers and tweeters. PA uses it to separately power subs and mains, but electric bass cabs are all full range, so there's no point in, for instance, bi-amping a 1x18/4x10, because both cabs share roughly 80% of the same frequency coverage.

Billy Apple Posted January 14, 2014 Author Share Posted January 14, 2014 I'm asking because I was looking at an Ampeg SVT VR which has 2 channels. I was told that each channel was 150 watts, but to get 300 watts like a CL you'd need to bi-amp it. Is this true, and how would it be done?

Woodinblack Posted January 14, 2014 Share Posted January 14, 2014 A friend of mine wrote a 'thing' for seymore duncan on multi amp setups. I don't know if it will help with what you want to do, but it is useful and even if it isn't what you want to do, fairly amusing http://www.seymourduncan.com/blog/the-tone-garage/multi-amp-rigs-101/ Quote Link to comment Share on other sites More sharing options...

There are two i/p channels, but only 1 power amp. It will deliver 300w (valve watts...) into an appropriate cab (8x10..?). There is no bridging mode (only 1 amp...) and cannot be 'bi-amped'. Could be wrong... Quote Link to comment Share on other sites More sharing options...

0175westwood29 Posted January 14, 2014 Share Posted January 14, 2014 i think thats just a way of running both channels at the same time bud. andy Quote Link to comment Share on other sites More sharing options...

[/quote] Yes; confusingly this is also called 'bridging' by some. Used on Fender Bassman amps, to get the use of both channel's EQ, and 'fatten up' the signal somewhat. An old Hiwatt stunt, too. Some amps (no name springs to mind, but I'm old.... ) can drive 1 channel [i]into [/i]the other, as a booster, or additional pre-amp. Not the Ampeg, though.
