Don’ts
• Do not
ground any red terminal.
• Do not
operate the amplifi er while standing in water.
• Do not
spill water or other liquids into or on the amplifi er.
• Do not
use the amplifi er if the electrical cord is frayed or broken.
• Do not
use the unit near stoves, radiators or other heat generating devices.
• Do not EVER
connect the output of the amplifi er to any other voltage source.
• Do not
run the output of any amplifi er channel back into another input
channel.
• Do not
parallel or series connect an amplifi er output with any other amplifi er
output.
• Do not
drive the inputs with a voltage greater than that required to drive the
amplifi er to full output.
Precautions & Warnings
Voltage:
Make sure the AC mains voltage is correct and is the same as that printed on the rear of the
amplifi er. Damage caused by using improper voltage is not covered by warranty. Be sure to
use high quality power outlets and strips that can withstand the power requirements of the
amplifi er.
Shock Hazard:
Face Audio® amplifi ers produce hazardous output voltages. The actual current draw an
amplifi er demands depends on many factors such as load, output level and the crest factor
of programmed material. The power requirement of Face Audio® amplifi ers is rated under
typical usage conditions with both channels driven so that peaks are just at the clipping point
(maximum current draw for each amplifi er is listed in the specifi cations
section). To avoid electrical shock please:
• Make sure the power switch is off before making any input or output
connections and before plugging in the amplifi er.
• Do not touch any exposed speaker wiring while the amplifi er is operating.
• Do not remove the top cover of the amplifi er as there are no user serviceable
parts inside.
Connectors & Cables:
Always use high quality speaker cable of the correct gauge for the application and only use
shielded balanced wire for the inputs. Poor cabling will be the root cause for most of the prob-
lems you encounter.
Speaker/Driver Damage:
Only appropriately rated speakers/drivers should be used with Face Audio® amplifi ers to
avoid damage to speakers/drivers. Turning the gain controls all the way down before power-
ing-up the amplifi er is recommended to prevent speaker damage.
Face Audio® will not be
responsible for damaged speakers
.
If you are unsure about the capacity of your speakers
please consult your speaker manufacturer. Any harsh pops or cracking distortion may be an
indication of the speaker voice coil striking the magnet assembly, if these symptoms should
arise reduce power immediately. A single high-power crescendo can damage high-frequency
drivers almost instantaneously while low-frequency drivers can usually withstand higher
power levels for only a few seconds before they fail. Face Audio® recommends using ampli-
fi ers of this power range to achieve cleaner sound rather than solely for increased volume.
