The Saturnworks 2:4 Active Stereo Buffered Splitter is an active buffered splitter that takes two input signals and sends each to two outputs, splitting two signals four ways without tone or level loss. Saturnworks describes it as perfect for splitting stereo signals, such as feeding the left and right outputs of a stereo pedalboard to two amps or destinations. It is an analog circuit, handcrafted in the USA, and runs on standard 9V DC center negative pedal power1.
How it works
The splitter uses four separate buffer circuits, one for each output, to ensure the signal on every output stays strong. A buffer is a simple circuit that keeps a guitar's tone from dulling as it passes through long cables and multiple pedals, and having one per output means each destination gets a clean, low-impedance copy of the signal. RockBoard's PedalPedia specifies a 1M input impedance and an output impedance of under 100 ohms, which is what lets the unit drive long cable runs without level or tone loss1.
The jacks are heavy duty Neutrik 1/4" TS jacks, and the power connection is a top-quality Lumberg power jack1.
Using it as a 1:2 splitter
You do not have to feed it a stereo signal. according to RockBoard's PedalPedia, you can use just one of the two input channels if you need a regular 1:2 active splitter, taking one instrument or pedal output and sending it to two destinations1.
Bass setup
The 4-way splitter can also be set up specifically for bass. RockBoard's PedalPedia says a bass setup is available on request: if you want it, you simply send a message after ordering1.

Because this is an active splitter, it needs a 9V DC center negative supply to operate. It is not a passive splitter that works without power.

Questions
Can the Saturnworks 2:4 splitter be used as a 1:2 splitter?
Yes. According to the maker, you can use just one of the two input channels if you need a regular 1:2 active splitter, leaving the second channel unused. That makes the same box work either as a stereo 2:4 splitter or as a mono one-in, two-out splitter.
What power supply does the Saturnworks 2:4 splitter need?
It runs on standard 9V DC center negative pedal power, the same supply most pedals use, through a top-quality Lumberg power jack. Because it is an active splitter with four buffer circuits, it needs power to run and cannot be used without a supply.
Is the Saturnworks 2:4 splitter analog?
Yes. The maker lists the circuit type as analog, and the unit uses four separate buffer circuits, one for each output, to keep the signal on every output strong and clean.
Is there a bass version of the Saturnworks splitter?
Yes. The maker says the 4-way splitter can be set up specifically for bass, and that a bass setup is available on request: you simply send a message after ordering to have it configured that way.
Where is the Saturnworks 2:4 splitter made?
The Saturnworks 4-way active splitter is handcrafted in the USA with high quality components, and it uses high quality wire also made in the USA.
