NAD 3020A stereo amplifier specifications Back to NRPavs Home
NAD 3020A stereo amplifier - charcoal grey :
The NAD 3020 can be used as the heart of an elaborate audiophile sound system
For example, the pre-amp outputs can be connected to any high quality separate power amplifier
To use a separate high power amplifier for your main stereo speakers while continuing to use the NAD 3020'S inbuilt power amp for headphones or extension speakers, simply install Y adaptors to split the signal from the pre-amp out jacks
The pre-amp stage is capable of driving several power amplifiers in parallel, or the long signal cables required to connect to power amplifiers located near the speakers, or to powered speakers
