Overview
|
The FP-PA20 features a
balanced line level input that may be connected unbalanced. A
front panel gain control is designed to be adjusted either
manually or with a trimming screwdriver
The gain range will accommodate standard unbalanced levels as well
as professional balanced levels. The output will drive an 8 Ohms
speaker or multiple speakers connected to present an 8 Ohms load
to the amplifier
Audio levels that could cause the amplified output to clip are
compressed using two dynamic time constants designed to preserve
aural transparency. Normal audio level signals remain unaffected
by the compressor thereby preserving audio dynamics and preventing
the compressor from increasing feedback potential when the
amplifier is used for paging
The FP-PA20 produces average audio levels and audio clarity
normally expected of amplifiers delivering much higher output
power
