Members 55fmj Posted January 26, 2010 Members Share Posted January 26, 2010 What is the purpose of the "biamp" jack on the back of the Peavey SP2's ( or any speaker for that matter ) as opposed to the "full range" jack ? What benefits are there of using the special speakon biamp plug in the biamp jack instead of just using the full range 1/4 jack ? Thanks Link to comment Share on other sites More sharing options...

Members gonzobassman Posted January 26, 2010 Members Share Posted January 26, 2010 when you use the bi-amp jack,you need to be sending only highs to the horn,and only mids(or los I suppose) to the speaker.Hence the term Bi-Amp. Link to comment Share on other sites More sharing options...
Members srp72ee Posted January 26, 2010 Members Share Posted January 26, 2010 The Bi-amp jack typically takes a 4 conductor cable into the speakon (2 for highs, 2 for lows). It's designed to reduce the cabling to the speakers and make it more "fool proof" and simple. Link to comment Share on other sites More sharing options...
CMS Author Craig Vecchione Posted January 26, 2010 CMS Author Share Posted January 26, 2010 Just to cover all bases, the biamp jack bypasses the passive crossover network in the speaker. The HF circuit runs directly to the HF horn, and LF runs directly to the LF driver. You need to use an active crossover and two amp channels to utilize this. Bi-amping offers somewhat clearer sound and wastes less amplifier power than a passive fullrange setup. Link to comment Share on other sites More sharing options...
