Saturnworks’ wide variety of mixer and summer pedals lets you combine signals of all tastes and textures.
Check out our FAQs, or the bottom of this page, for more detailed information on the differences between passive and active summers/mixers.
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 channel will minimally affect 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, 3-Channel Passive Summer with Switches
A simple passive mixer to combine two signals into one, with controls to fine tune the levels.
The Saturnworks passive mixers and summers take two or three inputs and combines them to one output with volume control for each channel to allow fine volume trimming. The versions with switches adds on/off switches to each channel. The ABC summer is comparable to the Morley ABC combiner.
The passive mixers and summers use summing resistors to minimize crosstalk between channels.
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 bass version tweaks the design to allow the bass’ lower frequencies to enter the mixer circuit
Active 2-Channel Mixer, Active 2-Channel Mixer with Switches, Active 3-Channel Mixer, Active 4-Channel Mixer with Switches, Active 5-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 combine inputs 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. This is known as crosstalk. The active version fixes crosstalk problems by using active circuitry to isolate both channels. This means that one channel’s level doesn’t affect the level of the other(s). 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. It should be used as a dedicated MP3 input only.
Saturnworks summers and mixer pedals include high quality features and components including:
- Durable cast-aluminum enclosures – the black versions feature black powder coated finishes.
- Heavy duty Neutrik jacks – the black versions feature premium Switchcraft jacks.
- All Saturnworks pedals are handcrafted and bench-tested in the USA.
- A one-year warranty against defects.
Saturnworks pedals can be upgrade with a variety of premium upgrades and customizations, including our phenomenally smooth, quiet, and extremely durable soft click latching switch. Contact us for details.
Passive vs Active
Saturnworks mixers come in two flavors: passive and active. Read on to learn more.
Passive and active mixers/summers both have their advantages and disadvantages.
If you just wire two signals together (like a y-cable, for example), they essentially become the same circuit. Being simply hooked together, whatever you do to one side you do to the other. With nothing to prevent interaction between the two channels, if you turn one side down the other will get softer as well. This is called crosstalk. Passive mixers are a step up from a y-cable in that they use summing resistors to combine the signals. This reduces (but does not eliminate) crosstalk. Depending on the types of signals being mixed, with a passive mixer, if you turn one side down completely the other side gets around 20% softer. While you can minimize crosstalk with a passive mixer, you cannot eliminate it altogether.
Passive mixers can have problems when trying to mix signals with different impedance. If you’re trying to mix a standard high-impedance guitar signal with a low-impedance signal from a keyboard or MP3 player, for example, the stronger low-impedance signal can cancel out the guitar signal altogether. So while inexpensive and simple, passive mixers work best when you’re okay with some degree of crosstalk, and you’re combining signals that have more or less the same impedance.
Active mixers/summers are often a bit larger, more expensive, and require power to function. However, they do offer some key performance advantages. Active mixers and summers eliminate crosstalk between channels. This means that you can turn one channel down without affecting the level of the other(s). Active mixers/summers also balance mismatched impedance so that you can combine a wider range of signal types.
The right mixer for you?
Of course the big question is what type of mixer you need. The type of mixer/summer that will be best for you depends on your setup, the types of signals you’d like to combine, and the features you might like. Passive mixing/summing works well in many cases, and Saturnworks has provided passive mixers/summers to many thousands of happy customers. From a technical perspective, active summing/mixing is the best way to combine two signals. But the mixer you select depends on your specific needs and budget.
