This is where you connect serial eff ects before the MAIN MIX FADER control. These serial eff ects usually are compressors
or equalizers. The send is low-impedance (150 ohms), capable of driving any line-level device. The return is high-
impedance (10k ohms) and can be driven by almost any device. Specialty “Y” cables, designed just for this applica on,
are widely available on shops. Specialty “Y” cables, developed just for these jacks, are widely available on shops. Proel
