Power/Protect indicators
The power light will illuminate in green when the amplifier is getting
power and playing. The light will illuminate in red if the amp enters
protect mode in the event of conditions such as over/under voltage,
short circuit, amplifier output circuit failure, or excessive heat.

SIGNAL INPUT
• Line-level inputs: If your source unit offers preamp outputs,
connect to the amplifier's L and R preamp inputs using RCA patch
cables.
• High-level inputs: If your audio system's source unit does not
have line-level outputs, use the supplied high-level input adapters
to connect to either the front or the rear speaker output wires of
your source unit. Use solder, butt connectors, or your preferred
splicing method. The 12-volt DC offset feature will turn the
amplifier on when it senses signal.
• Input level selection: If you're sending signal to the amplifier
using low-level outputs from your source unit, slide the input level
selector to "LO." If using high-level outputs from your source unit,
slide the selector to "HI."
