19. EFFECTS LOOP LINE OUT:
Sends a signal out to your effects devices
or signal processors. Lets you add
effects, with lowest noise. Uses a shield-
ed signal cable with mono 1/4” plugs.
Also doubles as a source for a post-EQ,
pre-amp signal to send your signal to a
mixing board, recorder, powered moni-
tor or external amplifier.
20. EFFECTS LOOP LINE IN: Re-
ceives the signal from your effects or
processors. Uses a shielded cable with
mono 1/4” plugs. Also doubles as a
direct feed to the power amp section,
bypassing the input and preamp stages.
Useful for “slaving” a pair of amps
together.
21. SPEAKERS: Connects the amp to
your speaker cabinet(s). Uses speaker
cables with mono 1/4” plugs. These
jacks are wired in parallel. Make sure that
your speaker combination never totals
less than 2 ohms! Use the chart below to
help determine parallel loads. If in doubt,
ask your dealer.
CAB IMP # CABS TOTAL IMP
4 ohms 2 2 ohms
8 ohms 2 4 ohms
8 ohms 4 2 ohms
16 ohms 2 8 ohms
16 ohms 4 4 ohms
16 ohms 8 2 ohms
22. POWERCORD: Connects the amp
to a grounded AC power outlet. Use
only a grounded outlet! DO NOT
defeat the ground prong of the cord!
If
the amplifier is used outside of the
United States, see the area’s Crate deal-
er for the proper power cord or consult a
local professional electrician.
