Specifications
NAD 7220PE Stereo Receiver
Note: Specifications are measured in accordance with EIA Standard RS-
490 (IHF A-202) for amplifiers and ANSI-IEEE Standard 185 (1975), i.e.
IHF T-200, for tuners. Amplifier measurements referred to 8 ohms are
taken with the Speaker Impedance selector set to 8Q (High).
Measurements for 4 and 2 ohms are taken'with Impedance
selector at 4Q (Normal).
