S. IEC POWER SOCKET -
Connect the included power cord to a
grounded AC receptacle in compliance
with the voltage and frequency ratings
specified on the rear panel of your
amplifier.
T. PARALLEL SPEAKER OUTPUTS - Use the 1/4"
phone jacks and Speakon ® connector in any
combination to connect a total speaker load of
4–ohms minimum. Combo units have a 4-ohm
internal speaker load for maximum power output.
The following configurations are recommended:
• One 4–ohm speaker
• Two 8–ohm speakers
U. HEADPHONES - Connect your headphones here.
Disconnect speaker connections for private
listening.
V. AUX IN - RCA input jacks for connecting your drum
machine or CD/tape player. Control the level of this
input at its source.
W. EFFECTS - (1) Effects Loop - Connect SEND to the
input of your effects device and the output of the
effects device to RETURN.
(2) Multiple Amplifiers -
Connect SEND on the primary unit to RETURN on
the auxiliary unit. The primary unit controls all
auxiliary units except MASTER.
X. TUNER OUT - Connection for your bass tuner. Use
MUTE {O} for silent tune-ups.
Y. HORN LEVEL -
(combo units only) Adjusts the
volume level of the horn.
Z. FUSE - (combo units only)
Protects the horn from overload
damage. If the horn stops

J. FX BLEND - Adjusts the amount of effects loop
“wet” signal mixed with the “dry” signal.
K. PRE/POST - Supplies the LINE OUT {N} jack with
the signal either before or after it is processed by the
amplifier’s equalization/tone circuits.
PRE—EQ bypassed
POST—EQ active
L. LINE LEVEL - Adjusts the output level of the LINE
OUT jack {N}.
M. GROUND LIFT - Disconnects the LINE OUT {N}
ground connection (pin-1) which may reduce hum
noise in some situations.
GROUNDED (normal)
GROUND LIFTED
N. LINE OUT - This jack allows you to send signal from
the preamp section out to an external source (such
as a house mixing console or a recording device).
The on board “level” control allows for adjustment of
signal strength. Use the “Pre/Post” control to select
if you would prefer the bass signal to be affected by
the EQ changes you make (post) or before the EQ, to
give an unaffected signal (pre). The “Ground Lift” is
there to eliminate buzz resulting from connection to
improperly grounded equipment.
O. MUTE - Disables all amplifier outputs except for
TUNER OUT {X}.
•
The LED flashes when MUTE is
active.
P. MASTER - Adjusts the power amp signal level. Use
together with VOLUME {C} to set the overall
loudness of the amplifier.
•
PWR AMP CLIP—Indicates power amp clipping.
Reduce MASTER level if you hear distortion when
this LED is on.
Q. POWER - Switches the amplifier on-off. Illuminates
when the unit is powered on.
