Marantz PM5005 - Manual (Page 40)

Explanation of terms
Speaker impedance
This is an AC resistance value, indicated in Ω (Ohms).
Greater power can be obtained when this value is smaller.
Source direct
Playback with higher fidelity to the source becomes possible, as input
audio signals are output by bypassing the audio quality-control circuits
(BASS/TREBLE/BALANCE).
Protection circuit
This is a function to prevent damage to devices within the power supply
when an abnormality such as an overload, excess voltage occurs or over
temperature for any reason.
If a malfunction occurs in this unit, the power indicator blinks red and the
unit switches to standby mode.
