14. AC LINE IN: Firmly plug the supplied
AC power cord into this socket, pushing
it in until it is fully seated. Plug the male
end of the cord into a grounded AC
outlet.
DO NOT DEFEAT THE GROUND
PRONG OF THE AC PLUG!
15. FUSE: This protects the unit from
damage due to overload conditions or
power line surges. If the fuse blows,
replace it only with the same size and
type.
16. POLARITY: Place this switch in
the position that provides the least
electrical buzz from the unit.
17. BIAS SECTION: These two controls and
sets of LEDs allow the user to properly
bias the power amp. See "Setting Tube
Bias" on page 5 for a complete
description of how to use this section.
18. SLAVE OUT: This jack receives the
same signal that is being sent to the
power amp. It is useful for powering
another amp (slave) from this unit’s
preamp.
19. BALANCED OUT: This XLR type jack is
the output at the power amp in. Thus,
it will include any processing done in
the Preamp Out/Power Amp loop [20,
21]. This signal can be used to feed
an external power amplier, mixing
console, or house PA system.
20. POWER AMP IN: This jack accepts a
signal to be sent to the power amp and
the Slave Out jack [18]. Using this jack
breaks the path from the signal that was
present at the Preamp Out jack [21].
This can be used as a post-Master [10]
patch point.
21. PREAMP OUT: This jack carries the
post-Master [10] signal. Using this jack
does not break the path to the power
amp. This signal can be used to feed
an external power amplier, mixing
console, or house PA system.
22. IMPEDANCE SELECTOR: Use this
switch to match the output impedance
of the amp to the speaker(s) being used
(2 Ω or 4 Ω). For help in determining the
total impedance of your system, consult
the table below.
Cabinet

Impedance
2 Ω 1 2 Ω
4 Ω 1 4 Ω
4 Ω 2 2 Ω
8 Ω 2 4 Ω
8 Ω 4 2 Ω
23. SPEAKER OUT: Two 1/4" phone jacks
and one Speakon
®
jack are provided for
connecting speakers to the unit. These
jacks are wired in parallel to each other.
When operating at or near full power,
the Speakon jack is recommended
for use rather than the 1/4" speaker
jacks due to its higher current handling
capability.
Use only (non-shielded) speaker
cables for speaker connections.
Do not use (shielded) instrument
cables as they may overheat.
