Step 4 .
Set the input power.
Adjust the loudspeaker tap using the 70V range until an acceptable
balance between high/mid loudspeakers and the FB-3862CU-AM is
achieved. (Factory-preset: 30W@70.7 Volt)
Note
Setting position “Low-Z” can be used in
UL1480A Category
UEAY
and
CAN/CSA C22.2 No.205 Category UEAY7
.
CAUTION
Do not use the Low-Z setting with an amplifier that is designed for use with a 70V system. Damage to the
amplifier and/or speaker may occur. If you are installing the FB-3862CU-AM as part of a bi-amplified
system (electronics crossover feeding high/mid and low frequency amplifier channels) with low impedance
amplifiers (4
Ω
or 8
Ω
outputs), use the Low-Z direct setting. A high pass filter set at 40Hz and low pass filter
set at 100Hz will help protect the FB-3862CU-AM from extreme low frequencies and provide an
omnidirectional low frequency source.
Step 5 .
Attach the front grill.
Push the grille up with the edge slides into the slit of the speaker till it gets flat to the speaker frame.
