The relay-controlled hard bypass switch includes an auto-bypass function in case of power failure for safety. Servo-balanced inputs and outputs are equipped with gold-plated XLR and 6.3 mm jack connectors. High-quality illuminated faders, ALPS grid potentiometers, and illuminated switches provide absolute durability. A shielded toroidal transformer minimizes interference. The super-rugged metal chassis ensures exceptional reliability, even under the harshest conditions.
