Precautions

The 20/20 AD is a rugged device with extensive electronic protection. However, you should observe the same reasonable precautions that apply to any piece of audio equipment:

Always use the correct line voltage.

Do not install the 20/20 AD in a closed, unventilated rack, or directly above heat-producing equipment such as power amplifiers.

Never attach audio power amplifier outputs (speaker outputs) directly to any of the 20/20 AD's connectors.

To prevent fire or shock hazard, do not expose the 20/20 AD to rain or moisture.
