CAUTION: If the impedance of your speakers is 4 OHMS, do not use both the speaker A and speaker B terminal at the same time as the net impedance may be low enough to damage your amplifier.
Caring for your PYRAMID amplifier
Your PYRAMID amplifier is an example of superior design and craftsmanship. The following suggestions will help you care for your amplifier so you can enjoy years of use:
•Keep the amplifier dry. If it gets wet, wipe immediately.
•Use the amplifier only in
•Handle the amplifier away from dust and dirt.
•Wipe occasionally with a damp cloth to keep it looking
new.
Do not use harsh chemical, solvents or detergents!
Replacing a fuse
This amplifier requires a fuse with the proper rating for protection from power surges and short circuits. If the amplifier suddenly turns off or will not turn on, the fuse is properly blown.
Remove the old fuse and replace it with an identical, serviceable fuse:
PA600X = 6A
PA1800X = 7A
CAUTION: Never use a fuse with a higher rating.
