The SPLIFF is a 3-way splitter discrete Class-A buffers with one output transformer isolated with phase side switch. Indicator Green LED for active, Red LED mutes OUT 1-3. OUT 3 is transformer isolated with a phase switch that can be selected with thumb. Tuner out is always active. The SPLIFF is low current, so it can run on a 9vdc battery for a long time or DC inlet 9-24vdc. MOSFET input protects if the wrong orientation adaptor is connected, no more damage internally. Proudly made in North America.
