Can anyone tell me what is the purpose/function of the mini-jack input on the front panel? It's not listed or mentioned in the manual or their website. This thing sounds great for the money by the way.
Thanks, Sam
Its a line level input. You would use it for something like a smart phone or tablet. Its on the front for easier access.
Thanks for the info. I knew I wouldn't be so lucky that it would be a minijack output for headphones.
