A handy little passive splitter/summer pedal that allows you either to split one signal into two or combine two signals into one.
The Saturnworks passive splitter/summer can be used to passively split one signal into two; or, turn it over to combine (sum) two signals into one.
Unlike Y-cables, which simply wire the jacks together, the Saturnworks splitter/combiner utilizes summing resistors to minimize crosstalk—in other words, the level of one signal affecting the level of the other.
The 2-channel patch bay + summer/splitter variation has a toggle that lets you switch the pedal between a 2-channel patch bay, or a passive summer/splitter.
Passive 2-Channel Mini Mixer, 2-Channel mixer with Switches
A simple passive mixer to combine two signals into one, with controls to fine tune the levels.
The Saturnworks passive mixer takes two signals and combines them to one output with volume control for each channel to allow fine volume trimming. The version with switches adds on/off switches to each channel.
The passive mixers use summing resistors to minimize crosstalk between channels.
Active 2-3 Channel Summer, Bass Active 2-3 Channel Summer
An active summer/combiner pedal combines either two or three signals into one without any tone loss or crosstalk between channels.
The Saturnworks active summer combines two signals into one, using active circuitry to eliminate crosstalk and balance mismatched impedance. Unlike Y-cables, which simply wire the jacks together, or passive summers, which can’t completely get rid of crosstalk, the Saturnworks active summer utilizes active electronics to eliminate crosstalk—in other words, the level of one signal affecting the level of the other. The circuit also helps with mismatched impedance.
The active summer features a single knob to trim the output of the summed signals.
The bass version tweaks the design to allow the bass’ lower frequencies to enter the mixer circuit
Active 2-Channel Mixer, Bass Active 2-Channel Mixer, Active 2-Channel Mixer with Switches, Bass 2-Channel Active Mixer with Switches, Active 3-Channel Mixer, Bass Active 3-Channel Mixer with Switches, Active 4-Channel Mixer with Switches, Bass Active 4-Channel Mixer with Switches, and MP3 Mods
Using active electronics to balance the signals and eliminate crosstalk, the Saturnworks 2 and 3 channel active mixers blend two inputs into one output. Saturnworks mixers can be used to combine inputs coming from various instruments with differing impedance. Saturnworks active mixers are also perfect for the mixer section of a parallel pedal chain setup.
While inexpensive and simple, passive mixers cannot isolate the channels. If you turn down one channel on a passive mixer, the other gets slightly softer as well – a phenomenon known as crosstalk. The active mixer fixes that problem by using active circuitry to isolate both channels, so that one channel’s level doesn’t affect the level of the other. The active circuitry also balances mismatched input impedance.
Saturnworks active mixer pedal comes in 2, 3, and 4 channel versions as well as versions with or without independent footswitches for each channel.
The bass versions tweak the design to allow the bass’ lower frequencies to enter the mixer circuit.
The versions with the MP3 mod modifies one of the inputs of the mixer to accept a low-impedance TRS input from an MP3, computer, or phone. The pedal mixes both the stereo MP3 input and the guitar input into a single mono (TS) output. The MP3 mod versions come with a 1/4″ – 1/8″ adapter to make plugging in an Mp3 player a breeze. Please note: the MP3 input does not work well for a standard guitar input and should be used as a dedicated MP3 input only.
