shows the state of various protection systems (power on/off detection, output protection, DC detection), a
TEMP indicator that indicates heat sink overheating, and a REMOTE indicator that indicates the external
remote status.
• Variable-speed low-noise fans ensure high reliability.
• The PC3301N enables parallel connection of multiple high-impedance speakers that support 100 V line
output.
