Notice:
If either the CH1 or CH2 PROTECT indicator light is yellow, there is no output
signal. Carefully check the cable connections. More information can be found
in the “Connecting the Cables” section.
Precautions
When using the DA, pay particular attention to the following issues.
Notice:
Make sure all cables are connected properly before turning on the DA. Refer
to the “Connecting the Cables” section for more information.
Pay particular attention to which audio input source is selected and configure
the output signal level appropriately, as this can save electricity.
Do not connect the grounding output cable with the grounding input cable as
this causes a short circuit to occur.
Warning!
Do not alter the circuit board or schematic diagram.
When the CLIP indicator light is flashing red, immediately reduce the audio
volume. If peak clipping occurs for too long, the DA could be damaged.
If the audio signal or peak clipping signal is too high, the speakers could be
damaged.
