[. . . ] This LED indicates that AC power is supplied to the unit, the power switch is on and the unit is functioning properly. To avoid damage to your hearing, make sure to turn the dial fully counterclockwise before using headphones. Slowly turn the knob clockwise until a comfortable listening level is set. Two four-segment LED arrays are provided to monitor the levels of the main Left/Right outputs. If phantom power is used, do not connect unbalanced dynamic microphones or other devices to the XLR inputs that cannot handle this Voltage. Depressing this switch adds the tape return to the Control Room and Headphone Outputs (24) for zero latency monitoring. Depressing this switch routes the signal from the Tape Inputs to the Main Outputs (27). Engaging this switch enhances the signal by adding both bass and treble frequencies. This is especially effective at lower volumes or for tape/CD playback. When engaged, it can improve clarity by removing low frequencies that can make a mix sound muddy. This feature is especially useful when playing outside on a windy day or on a hollow, noisy stage. Engaging this switch removes those frequencies from the system and restores power to where it's needed. The EFX/Return Level Control adjusts the level sent to the Left/Right main bus from the return inputs. Because of the wide range of gain adjustment, signal levels up to +14 dBu can be accommodated. The tip is the positive input and should be used for unbalanced inputs. It has 20 dB less gain than the XLR input and does not have phantom power available.
