Teko-2.7 is a powerful and versatile two-channel tone control system. It features an active/passive crossover, three-band EQ with parametric mids, post-FX loop, phase control, and master level control. The active/passive crossover allows you to tailor the frequencies that pass through each speaker, the three-band EQ gives you access to tweak the mids, high, and low end of your mix independently, and the post-FX loop allows you to connect external EQ, effects, and other audio processors for additional sound sculpting options. Additionally, the phase control allows you to align the timing of both speakers for a more cohesive soundstage, and the master level control helps to keep your mix balanced.
