Expert Audio Engineering Commentary
Headroom Notes
No headphone output; a line-level source for an amplifier. The manual states 2.0 Vrms output and a consumption of under 5 W from a single USB port, which is more than the 2.5 W a USB 2.0 port is obliged to give — on a weak hub it is worth watching.
