SUNN 300T SETUP PROCEDURES
To ensure optimum performance
from your Sunn 300T Bass Amplifier,
please follow these setup guidelines
and procedures.
1. Connect your Sunn 410H / Sunn 215 Bass
Loudspeaker Enclosure or equivalent to the parallel
speaker jacks located on the rear of the 300T
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 300T is 2Ω. Remember to
connect or disconnect any speaker enclosure to your
300T with the power off.
2. Set the SPEAKER IMPEDANCE switch to match
the power amp to the proper speaker impedance
load (item M, page 9).
3. Next, attach the 3-button footswitch and your
tuner to the TUNER OUT and FOOTSWITCH jacks
located on the rear of the amplifier.
4. Connect any effects processing devices through
the EFFECTS LOOP SEND and RETURN jacks on
the rear of the unit.
5. If sending your 300T’s 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.
