1. Connect your Sunn 410H / Sunn 215 Bass
Loudspeaker Enclosure or equivalent to the parallel
speaker jacks located on the rear of the 1200s
amplifier. Note: 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.
2. Next, attach the 3-button footswitch and your
tuner to the TUNER OUT and FOOTSWITCH jacks
located on the rear of the amplifier.
3. Connect any effects processing devices through
the EFFECTS LOOP SEND and RETURN jacks on
the rear of the unit.
4. If sending your 1200s’ signal to an external power
amplifier or main house mixer, connect a cord from
either the 1/4 inch or XLR LINE OUT jack to your
external power amplifier or mixer.
5. Make sure the HIGH and LOW tone controls are
in their center notched positions, the Graphic EQ is
“flat”, the compressors are OFF and the LOW, HIGH
and MID NOTCH buttons are out.
