SUNN 1200s REAR PANEL
A. SPEAKER JACKS - These are the plug-in
connections for your speaker enclosure(s) and are
wired in parallel. For improved performance, DO NOT
daisy chain multiple enclosures off the same jack. As a
rule of thumb, connect only one speaker enclosure per
output jack and remember the total minimum
impedance load for the 1200s is 2Ω. Remember to
connect or disconnect any speaker enclosure to your
1200s with the power off.
B. LINE CORD - This amplifier is equipped with a
grounding type supply cord to reduce the possibility
of shock hazard. Be sure to connect it to a grounded
AC receptacle. The line cord should be connected to
a suitable power source in accordance with voltage
and frequency as shown in the power rating on the
rear panel. If the 1200s is plugged into an outlet
rated at 15 amperes, dedicate this circuit solely to the
1200s. DO NOT ALTER THE AC PLUG.
C. RETURN - This 1/4 inch, balance / unbalanced,
tip-ring-sleeve, tip-sleeve, input jack is designed to
accept signal from an external processing device,
such as a digital delay or a chorus unit. The effects
loop will not operate without a plug inserted into
this jack.
D. SEND - This 1/4 inch, unbalanced, TS, output
jack is designed to send a signal to an external signal
processing device, such as a digital delay or a chorus
unit.
E. TUNER OUT - This 1/4 inch, unbalanced, TS,
output jack is designed to send your bass guitar's
signal to your tuning device (not included).
F. FOOTSWITCH - Plug-in connection for the
footswitch (P/N 053895) used to remotely turn on
and off the graphic equalizer, compressors and
change the channel selection. Using the footswitch
will override the front panel graphic equalizer,
compressor and the channel selection buttons.
NOTE: Any good quality patch cord will work with the
remote footswitch, however an unshielded speaker
type cord is preferable to a coax guitar cord.
