A 20 – Operation
Rear View
Looped-through input (hard-wired), RCA phono sockets for signal sources with high levels.
Input sockets = for the connection of audio sources (CD player, DVD player etc.)
Output sockets = for the connection of devices with high level input (stereo amplifiers, active loudspeakers etc.)
At the output sockets you can pick up the audio signal from the input sockets and route it to your stereo
amplifier, active loudspeakers or other devices with standard inputs for high levels. As the signal of the input
sockets is permanently available at the output sockets, you can listen to the looped-through audio signal via your
hi-fi system, even when the A 20 is turned off.
Mains connection with integrated wide-range switching power supply for 100 - 240 V AC.
Due to the integrated wide-range switching power supply, the A 20 can be operated with 110 V/60 Hz or
240 V/50 Hz.
