Analog Source
refers to any device which produces usable audio through an output jack. Examples include the headphone jacks of iPods, laptops, cell phones, etc.
2
Analog Amplifier
refers to any device which receives analog audio through an input jack. Examples include speaker or stereo 3.5mm and RCA inputs, etc.

ODAC achieves published performance when used with a single device. For best results driving external speakers or amplification systems, mechanically relieve
ODAC from the Objective2 amplifier by connecting any cable to ObODAC's front 3.5mm input jack (requires Custom, Dedicated RCA or 3.5mm DAC Line-
output jack).
