What is a Headphone Amp?
A headphone amp is a great little gadget for guitarists. About the size of a pack of cigarettes, a headphone amp allows you to just plug in an electric guitar and a set of headphones, and switch it on. Then crank up the volume because no one can hear but you! A headphone amp is ideal for practicing anytime, night or day, without disturbing friends, family, roommates or neighbors. Aside from simple amplification of the guitar signal, a headphone amp can also be a miniaturized portable studio with effects processor, amp modeling and rhythm machine. Analog and digital effects processors can emulate everything from heavy distortion to hard-core crunch, chorus, echo, funk and more. See how the effects sound through a variety of digital amps, from the Classic Fender tube amp of the 60s to Marshall, Vox and others. A built-in rhythm machine can provide several different rhythm patterns to serve as drummer. Then, with the press of a button, choose your venue and the headphone amp can place you
You need the headphone amp to hear line levels you can get them at most music stores that offer recording gear. Yes you would need to use the advanced config only. By far the simplest way is the way you aleardy had it but to make use of the case player you’d need to continually switch to a channel not in use. A or B and use the cue bus on your real dj mixer. I still don’t understand why you would want that functionality I’ve never needed a third player in 6 plus years of djing.
