AA. IEC POWER CORD SOCKET - Connect only the supplied
high-capacity power cord to a grounded AC receptacle
in compliance with the voltage and frequency ratings
specified on the rear panel of your TB-1200/600. Contact
Fender customer support for power cord replacement.
BB. PARALLEL SPEAKER OUTPUTS - Use any combination
of these outputs to connect speaker cabinets. Do not
violate the MINIMUM speaker load impedance, which is:
• 2 for the TB-1200 Head:
(two 4Ω speakers = 2Ω)
(one 4Ω and two 8Ω speakers = 2Ω)
(four 8Ω speakers = 2Ω)
• 4 for the TB-600 Head/Combo*:
(one 4Ω speaker = 4Ω)
(two 8Ω speakers = 4Ω)
(one 8Ω speaker and two 16Ω speakers = 4Ω)
(four 16Ω speakers = 4Ω)
*TB-600 Combo internal speaker = 8
CC. FOOTSWITCH - Connect a TBFS-4 footswitch here with
any length guitar or speaker cable to enable remote
on/off switching of Tube Overdrive, FX Loop and
Vari-Q™. The TBFS-4 includes a chromatic tuner which
automatically mutes the amplifier when enabled.
DD. TUNER OUTPUT - Connection for your bass tuner. This
"tube-influenced" output is always active, and can be
used as an additional "PRE" line output.
EE. INPUT - Alternate connection for bass guitar signal.
Useful in some rack configurations. NOTE: The front
panel INPUT {A} jack overrides this jack.
FF. PRE AMP OUTPUT/PWR AMP INPUT - For multiple
amp set-ups, connect the PRE AMP OUTPUT of the
primary unit to the PWR AMP INPUT on the auxiliary
unit. The primary unit controls all auxiliary units.
GG. RETURN / SEND - FX Loop jacks for external effects.
Connect SEND to the input of your effects device and
RETURN to the output of your effects device.
HH. –10dBV / +4dBu - FX Loop level. Sets nominal operating
level for external effects. Use +4dBu for professional
rack-style effects. Use -10dBV for battery operated pedal
effects.
II. TRIM - Adjust to compensate for external effects
devices volume difference when FX Loop is selected
with the footswitch. Full clockwise rotation provides
a +9dB boost, while full counter-clockwise provides a
-9dB cut. Also useful for a footswitchable solo boost
(clockwise rotation) when not using external effects.
JJ. LEVEL - Adjusts the output level of the BALANCED LINE
OUTPUT jack {MM}.
KK. PRE / POST - Use this control to select if you would
prefer the bass signal from the BALANCED LINE OUTPUT
jack {MM} to be affected by the preamp changes you
make (POST) or before the EQ, to give an unaffected
signal (PRE).
LL. GND / LIFT - The Ground Lift switch should normally be
in the GROUND (out) position. In the LIFT (in) position,
the ground connection (pin-1) of the BALANCED LINE
OUTPUT jack {MM} is disconnected from the chassis,
which may reduce hum noise in some situations.
MM. BALANCED LINE OUTPUT - A true electronically-
balanced XLR jack for output to studio and live
performance mixing consoles.
NN. HORN LEVEL - (TB-600 Combo only) Adjusts the volume
level of the horn.
OO. HORN FUSE - (TB-600 Combo
only) Protects the horn from
overload damage. If the horn
stops responding, replace the fuse
with the same type and rating as
specified on your amplifier (F2A, 250V).
NOTE: Jacks {DD}, {GG} and {FF} are balanced TRS (Tip/Ring/Sleeve) types, with tip=positive (+),
ring=negative (–) and sleeve=ground (GND). While standard shielded TS (Tip/Sleeve) “mono” guitar
cables may certainly be used, the use of “stereo” TRS cables, when available, may improve signal-to-
noise ratio and/or reduce hum.
