22. AC LINE IN:Firmly plug the supplied A Cpower cord
into this socket, pushing it in until it is fully seated. Plug
the male end of the cord into a grounded AC outlet. D O
NOT DEFEAT THE GROUND PRONG OF THE A C
P L U G !
23. FUSE: Protects amp from overloads and faulty A C
conditions. If fuse blows, replace only with same size
and type.
24. POLARITY: Place this switch in the position that pro-
vides the least electrical buzz from the unit.
25. BIAS S E C T I O N : These controls and LEDs allow the
user to properly bias the power amp (see owners man- u a l ) .
26. SLA V EO U T :This jack receives the same signal that
is being sent to the power amp. It is useful for powering
another amp (slave) from this units preamp.
27. PREAMP O U T: This jack carries the post-Master
(13) signal. It does not break the path to the power amp.
This signal can be used to feed an external power ampli- f i e r , mixing console, or house PA s y s t e m .
28. POWER A M PI N :This jack accepts a signal to be
sent to the power amp and the Slave Out jack (26). It does break the path from the Preamp Out jack (27).
T h i s
can be used as a post-Master (13) patch point.
29. LEVEL: This control adjusts the level of the signal at
the Balanced Out jack (31).
30. PRE/POST: This switch selects a direct out from the
bass (Pre) in the OUT position and the preamp signal
just before the Master (Post) in the IN position to be sent to the Balanced Out jack (31).
31. TRANSFORMER BALANCED O U T:This XLR-
type jack is the output as selected by the Pre/Post switch
and adjusted by the Level control (29). This signal can be used to feed an external power amplifier, mixing con-
sole, or house PA s y s t e m .
32. EFFECTS L O O PS E N D : This is a post-EQ, pre-
Master (13) patch point send jack. It does not break the
path through the preamp. When using an external signal p r o c e s s o r , connect the INPUT of the effect to this jack
using a shielded instrument cable to send the signal to the effect for processing.
33. EFFECTS L O O PR E T U R N : This is a pre-Master
(13) patch point return jack. It breaks the path through
the preamp. When using an external signal processor, connect the OUTPUT of the effect to this jack using a shielded instrument cable to feed the processed signal
into the power amp section.
34. TUNER OUT: This is a direct output from the instru-
ment which can be routed to a tuner. It is the only output that stays active when the Mute switch (3) is engaged.
35. FOOTSWITCH: This is a stereo jack which will oper-
ate with a standard dual footswitch. The tip of the plug controls the Mute operation, the ring controls the
Graphic EQ operation, while the sleeve acts as a ground common to both. With the footswitch inserted, both the
front panel and the footswitch Mute switches are active. The front panel Graphic EQ switch (15) must be IN f o r
the Graphic EQ footswitch to operate.
36. IMPEDANCE SELECT O R :Use this switch to
match the output impedance of the amp to the speak- er(s) being used (2 or 4 ohms).
37. SPEAKERS: These jacks are provided for connect-
ing speakers to the unit. While the 1/4 jacks are conve- nient, the Speakon
®connector is preferred for carrying
the heavy current from this amplifier.
38. RACK SUPPORT FASTENER: This is a 1/4-20
weld-nut which can be used to provide additional sup-
port for the rear pf the unit.
