[. . . ] When the DRI is programmed for use with ADVANTAGE RCIIs, labelling for the control voltages is shown as level & mute functions for Channels 1~12. Also, labelling for Logic Output 1 is shown as Off/On switching (Logic Output 2 is inactive). NOTE: Channel 12 (control voltage) is only available by converting Logic Output 2 via an internal jumper (see Control Voltage Outputs on pg. Adjustments are made with the computer mouse (or keyboard). Levels are adjusted by dragging the corresponding `faders' up or down. Each fader provides fifty-one volume (voltage) steps. Left-clicking above or below a fader will adjust the level five steps at a time. Right-clicking on a fader opens a drop-down menu for setting upper & lower limits for that fader. This restricts the volume (voltage) range of that fader, but only for remote controls which utilize `volume up' & `volume down' button definitions (i. e. . . Remote, Logic Inputs, & RS-232 Control Button Emulation). These upper & lower limits do not restrict software level adjustments, muting, or fader settings which are part of a preset. Left-clicking a Mute button will toggle that channel/output off & on. Left-clicking a Preset button will recall the corresponding preset from non-volatile memory. Left-clicking the Store button will open a dropdown menu for storing the current settings in any of the Presets 1~8. Left-clicking the Logic Output buttons will toggle them on & off. The title bar across the top of the Main screen will indicate the Device #, the custom Device Name, and the model of product being controlled. The PC Control Software can operate `off-line' (with no product connected) by opening a `new' file for the desired product. The Device # for `off-line' files is assigned sequentially as a negative number. 8 SETUP BUTTON DEFINITION SCREEN The Button Definition screen is used to assign specific `actions' to remote control buttons. ADVANTAGE infrared & wall-mount remote controls have twenty-eight buttons. However, the DRI supports twelve additional buttons, which are only available when using Remote ® Interface Kit or RS-232 control (see Remote Controls on pg. From the factory, the DRI is programmed for controlling an ADVANTAGE DLA93. Buttons 1~24 provide volume up, volume down, and mute functions for Channels 1~7 and the Main Output. Buttons 33~40 provide volume up, volume down, and mute functions for Channel 8, Aux Input, & Aux 1 Out. [. . . ] Eight of the DRI control voltages are each connected to two channels of an RCII, thereby providing common control of both left & right (stereo) signals. The DRI factory programming allows control of the RCII functions (level & mute) for the eight stereo sources (Channels 1~8). In addition, the DRI provides the ability to store and recall up to eight presets from non-volatile memory. Each preset may be programmed to affect any or all of the RCII functions mentioned above.
