In Stock. 45 Day Lowest Price - 100% Satisfaction Guarantee. Stereo 2-way/Mono 3-way crossover. All the inputs and outputs are TRS differentially balanced 1/4" jacks that are bolted down to the chassis. This "nutting down" of the jacks insures that even if someone stomps on a cable plugged into the unit, it's not going to tear up the circuit board inside.
