PF-350 / PF-500 Bass Guitar Amplifier
9. LIMIT LED: This LED illuminates when
the limiter circuit is activated, indicating
that the amplifier is nearing full output
and the limiter is keeping peak signals
from clipping the output.
10. LIMITER SWITCH: Press this switch in
to add the limiter circuit. If the signals
driving the amplifier start to peak, the
limiter will automatically reduce the
signals to prevent clipping, and the
LED[9]willflash.Thelimiterwillhelp
keep the amplifier’s output “clean” up to
high output levels and avoid potentially
damaging distortion.
11. FAULT LED: This LED illuminates amber
if the amp thermals and shuts down or
develops other fault conditions. See
“Fault/Thermal Considerations” on page
18 for more information.
12. AUDIO IN: The audio output from line-
level sources, such as an iPod
®
, MP3,
or CD player, can connect to this
1/8"TRSstereoinput.Theincoming
audio is mixed with the preamp signals,
so you can play along to a practice
track as you listen with headphones.
(The audio coming in here only plays in
the headphones, and appears nowhere
else. It is not affected by the volume
control.)
13. PHONES:Usethis1/8"TRSstereo
output to connect your headphones.
The output here is a mix of the line-level
signals reaching the amplifier, and any
incoming audio from the audio in
jack[12].
If you just want to listen and practice
through headphones, disconnect the
speaker-leveloutputs[18]fromthe
speaker cabinet. There is no harm in
playing the PF-350 without speakers.
Before putting on headphones, make
surethevolumecontrol[8]isturned
down, and (if connected) any external
audio source has its level turned down.
This will reduce the chance of hearing
damage due to loud volumes.
