Use the following formula to determine the fuse capacity according to the speaker’s input
capacity.
Po = I
2
R I =
P0 [W] : Speaker’s continuous input capacity (noise or RMS)
R [Ω] : Speaker’s nominal impedance
I [A] : Required fuse capacity
ex.) Speaker’s continuous input capacity: 100W
Speaker’s impedance: 8Ω
I = = 3.5
In this example, the required fuse capacity is calculated as 3.5 [A].
• SPEAKER CABLE
If you use a long speaker cable, use as thick a cable as possible to prevent deterioration of the
damping factor or power loss inside the cable. Even the thickest cable can be used for the
speaker terminal of this unit.
PORTABLE RACK MOUNTING
The amplifier intakes cool air through the front panel and exhausts warm air out the rear panel.
When mounting amplifiers in a portable rack, make sure the rear panel is completely open for
ventilation.
