headphone amp built in. There are two inputs, stereo RCA and stereo mini-jack,
along with RCA preamp outputs and a 3.5mm headphone jack.

(item numbers 772AW1 and 772AW2, sold separately) that can be powered using
Inputs: There are two analog inputs, stereo RCAs and a 3.5mm

they will accept pin connectors, spade connectors, single and dual banana plugs,
and bare wire up to 12 gauge. Two 70" lengths of 16 gauge wire are included

used to add an external amp, a powered subwoofer, or an audioengine wireless
adapter (item numbers 772AW1 and 772AW2, sold separately).

front panel. It controls the volume for the speaker level, preamp, and front
