Headroom Notes
A line source with no headphone output. SMSL rates it 2.5 Vrms on RCA and 5 Vrms on XLR — a quarter of a volt above the 2 V / 4 V convention, enough to matter if you are matching two sources by ear. Output impedance 100 ohms on both, which is high enough to be worth checking against the input impedance of a passive preamp.
