CONTROLS & CONNECTIONS
3.1.2 Headphone Channels: Level Controls
•Ext In. The external in knob controls the input level and amount of the Stereo Ext. In on the rear of the chassis for the channel.
•Mono. When the Mono button is pressed, the Stereo Ext. In will act as a mono input – summing the signals from the TIP and the RING of the ¼” connection.
•Mix. The Mix knob controls the amount of each of the two mixes A & B for the channel. As the knob is turned counterclockwise (left), the amount of Mix A increases, and the amount of Mix B decreases. As the knob is turned clockwise (right), the amount of Mix A decreases, and the amount of Mix B increases. With the Mix knob in the “12 o’clock position,” an equal amount of Mix A and Mix B is sent to the channel’s headphones.
•Mute. When the Mute button is pressed, both Mixes are muted for the channel. This is most commonly used as a type of “Solo” for the external stereo input.
•Level. The Level knob controls the volume level of the channel’s Phones output.
•Phones. This is the channel’s stereo headphone output.
