Listen Four Quarters

 is a four channel stereo mixer with 1/4” (6.35mm) TRS balanced outputs and 

1/8” (3.5mm) headphones output. Two mono channels with 

Pan

 knobs and two stereo channels with dual inputs 

provide optimal compatibility with both stereo and mono signals. The 

Listen Four

 

Quarters 

can be daisy-chained 

to other 

Listen

 modules to create a larger mixer with sub-mix outputs.

features include: 

• Four input channels (two with stereo inputs, two with mono inputs and a

 

Pan

 knob) 

• Headphone and main 1/4” outputs, each with separate 

Level

 knob 

• Balanced TRS outputs, switchable to stereo 

• Line level output driver with zero impedance, capable of driving long cables 

• Low noise, cross-talk, and bleed-through 

• Anti-pop feature that silences pops and thumps when the power is turned on 

• Headers in back allow for connecting to other
