8. Speaker Terminals – 5-way, 24k Gold Contact binding posts allow for multiple types of speaker connections.
(They are Banana Plugs, Ring Lugs, Spade Lugs, Pin Connectors, and stripped bare wire. Connecting to bare wire
is not recommended and should be considered only as a temporary option until other connectors are attached
to the ends of the speaker cable.)
9. Channel Fuses – 7A 120V Slow-Blow fuses protect the individual amplifier channels from power overload.
Replace only with same type fuse rated at the same amperage.
