QUALIA & Co INDIGO Series Owner's Manual - Caution
12
●
When connecting a cable, confirm that the power cable is not connected.
Connecting a cable with the power on may damage the Main Unit and the equipment to be connected, which may
result in an electric shock.
●
Before connecting equipment, thoroughly read the instruction manual for the power amplifier and turn off the
power. Then, connect the equipment following the instructions. Use high-quality connection cables.
●
DO NOT short-circuit the output terminal.
DO NOT place a shorting pin on the unbalanced output terminal.
Short-circuiting the output terminal will damage the internal circuit.
●
This device is not a balanced amplifier. When connecting a balanced cable, be sure to match the polarity of the
equipment to be connected with this equipment. If a cable needs to be customized so that it can be connected
properly, please contact the dealer or cable manufacturer. If the polarity does not match, no sound is generated
and the Main Unit and the connected equipment may be damaged.

When the polarity of the power amplifier is 2=HOT
Commercially available balanced cable can be used as is.
When the polarity of the power amplifier is 3=HOT
The balanced cable needs to be customized.
