Fender RUMBLE 150 Mode D'emploi page 7

For multiple amp set-ups, you can connect the SEND
from one Rumble amplifier to the RETURN of a second
Rumble amplifier. The preamp controls (volume and
tone) of first amplifier will control both amplifiers
K. AUX IN — Plug your CD player or mp3 player in here. The
amp controls do not affect this input. Adjust the volume
or tone of the aux signal at its source.
L. HEADPHONES — Plug your stereo headphones (32
ohms minimum impedance) in here. Speaker output is
automatically disabled.
M. FOOTSWITCH — Allows for remote switching of
OVERDRIVE. See the "Optional Footswitch" section for
details.
N. LINE OUT — Balanced output to connect to external
devices such as PA systems and recording consoles. The
level and tone of the LINE OUT signal are affected by all
preamp controls, including VOLUME. Pressing the GND
LIFT button IN may eliminate hum or buzz resulting from
connection to improperly grounded equipment.
O. HORN (COMBO AMPLIFIERS ONLY) — Switches the
horn ON or OFF. The horn will add crispness and sparkle
for more modern tones that are well suited for slap-style
funk.
P. POWER — Switches the amplifier ON or OFF as indicated
by the power light.
Q. IEC POWER CORD SOCKET — Connect the included
power cord to a grounded A/C electrical outlet in
accordance with the voltage and frequency ratings
specified on the rear panel of your amplifier.
Connect a footswitch to the amplifier to remotely enable
OVERDRIVE. Fender makes three footswitch pedals that will
work (shown at right with part numbers). Any generic single-
button latching-type footswitch will work. We recommend
the Fender LED FOOTSWITCH (P/N 0994052000) for best
performance. Contact your local Fender dealer to purchase
the Fender footswitch of your choice.
NOTE: If a footswitch is connected, the front panel switch will
still work, but it is possible for its position IN/OUT to become
backwards (i.e. IN=OFF), depending on the footswitch status.
The Overdrive light (LED) on the front panel will ALWAYS be
correct, but the LED in the footswitch may be incorrect. If
using a footswitch with an LED, keep the front panel switch in
the OUT position to have the correct status displayed on the
footswitch LED.
