Thank you for your purchase of a Fender SPL-M500
Stage Monitor Power Amplifier.  We are sure you will
find it to be a useful and unique product, providing
years of trouble free service in both permanent and
portable applications. Although intended primarily
for portable stage monitor use, the SPL-M500 is
also effective in sound reinforcement applications
where fixed microphones are used and feedback is
a problem.  

Employing a unique design, the SPL-M500 provides
a powerful tonal control system which fights
feedback while optimizing sound.  This design is
comprised of a sweepable high pass filter, a
sweepable low pass filter and three advanced
narrow band notch filters.  

This manual is arranged into four sections:

-  A description of the SPL-M500 panel features.
-  A section on basic connections and wiring.
-  A guide on operating the SPL-M500.
-  Product specification sheet.

WARNING:

-To reduce the risk of fire or shock hazard, do
not expose this amplifier to rain or moisture.  
-No user serviceable parts inside, refer 
servicing to qualified personnel only.
