The Markbass Pro Bass Mixer is a compact 3-channel mixer designed for bass and multi-instrument setups. It is an analog circuit built for pedalboards, and RockBoard's PedalPedia describes it as combining a rugged design with studio-grade versatility1. For a bass player, it is a way to blend a bass with other sources, such as a microphone or a second instrument, into a single output without a separate desk.
Channels and controls
Each of the three channels offers independent gain, volume, and tone shaping through two filters RockBoard's PedalPedia calls "Hifizer" and "Old School"1. That gives each source its own level and tone character before everything is summed, so a bass and a second instrument can be balanced against each other rather than run through one shared tone control.
Channel 3 includes phantom power for microphones or active pickups1, which means a mic'd source or an active bass can be connected directly to that channel without a separate power supply or preamp.
Outputs and linking
Signals can be routed to two outputs, and multiple mixers can be linked for expansion1. For players who need more than three channels, a second unit can be added rather than swapping to a larger mixer.
Power
The Pro Bass Mixer runs on 9V DC, center negative, and draws 120mA1. A pedalboard power supply output rated for at least that current is required.
A manual covering the unit in English, German, French, Spanish and Italian is available from the maker's product page1.
Where it sits on a board
As a mixer rather than a tone-shaping pedal, the Pro Bass Mixer sits alongside the preamp and switching categories: players blending several sources on a board may also look at Preamp Pedals or Switching Pedals, and Markbass's own Mark Vintage Pre covers the preamp role in the same range.
