[. . . ] ­ or ­ · Use PRE front panel controls to adjust Mic Preamp controls in Pro Tools. PRE Remote Control in Pro Tools The following PRE front panel controls can be remote-controlled in Pro Tools: · Input Gain · Input Source · Selecting one or more channels for editing · Input Impedance (Input Z) · 48V · Insert · Pad · Phase Invert · High-Pass Filter The following PRE front panel controls are not supported by remote control. · Oscillator on/off · MIDI channel assignment · Changing the Peak Hold setting of front panel Clip LEDs · Clearing of Clips on the front panel · Muting individual PRE outputs Chapter 3: Remote Operation 15 Connecting PRE to a Pro Tools System Audio Connections PRE must be physically connected to a Digidesign audio interface (such as a 192 I/O) in your Pro Tools system. To connect your PRE to your Pro Tools system: s 2 Connect a MIDI cable between the MIDI In port on your PRE and the MIDI Out port on your MIDI interface. 3 For additional PREs, daisy-chain them by connecting the MIDI Out port on the first PRE to the MIDI In port of the second PRE, and so on. For multiple PRE MIDI cabling considerations, see "Installations with Multiple PREs" on page 16. Setting PRE MIDI Channel To set global receive/transmit MIDI channel: 1 If you haven't done so already, connect AC power to PRE. 3 On the PRE front panel, press MIDI Chan. The LED should be lit; if not, press and release again. Connect PRE outputs to analog inputs on your Digidesign audio interface (for example, to connect PRE to a 192 I/O, use a DB-25 cable to connect the PRE outputs to the Analog Inputs on the 192 I/O). For installations with multiple PREs, repeat the above step. For each PRE output, note the respective audio interface input channels, as these will be the physical inputs you map PRE outputs to in Pro Tools. For example, PRE outputs 1­8 attached to a standard 192 I/O map to analog inputs 1­8; however, PRE outputs 1­8 attached to the second A/D card on a 192 I/O represent analog inputs 9­16. The Gain/Param display will display the current MIDI channel (1­16). 4 Turn the Gain/Param control clockwise to increment MIDI channel numbers, or counterclockwise to decrement channel numbers. The MIDI channel will be set once you stop moving the control; you do not need to press an Enter key to set the channel. 5 To exit MIDI Channel mode, press MIDI Chan MIDI Connections The following are basic instructions for connecting your PRE to a MIDI interface for remote control. Before you connect PRE MIDI Ins and Outs, connect and configure your MIDI interface according to the manufacturer's instructions, if you have not done so already. To connect a PRE to the MIDI interface: 1 Connect a MIDI cable between the MIDI Out port on your PRE and the MIDI In port on your MIDI interface. again. 6 Repeat the above steps for additional PREs. Installations with Multiple PREs To control multiple PREs via a single MIDI port, set each unit to a unique MIDI channel number. Keep in mind that if PRE units are set to the same MIDI channel on a single MIDI port, their controls will operate in a "linked" fashion-- changing a setting on one unit will change the setting on all units. 16 PRE Guide With a multi-port MIDI interface, every unit must be daisy-chained from a single port on your MIDI interface. Connect the MIDI Out port of the MIDI interface to the MIDI In port of the first PRE, then connect the MIDI Out port of the first PRE to the MIDI In port of the second PRE, and so on. Make sure to connect the MIDI Out port of the last PRE to the MIDI In port of the MIDI interface. 3 Shut down the computer. 5 Turn off PRE 6 Turn off any synchronization, MIDI, or other peripherals or interfaces. 7 Turn off your drives. With multiple PREs, it is easier to keep track of each unit in Pro Tools by setting MIDI channels in ascending order, in relation to the physical position of the PREs (for example, in the order they are stacked in a rack). Configuring OMS for Your PRE Before using a PRE with Pro Tools, you must first configure it as an OMS device. The following are basic instructions for configuring your PRE in OMS. If you are installing OMS for the first time, refer to your Getting Started with HD Guide. If you are not familiar with OMS, OMS devices, or how to configure OMS Setup, refer to the OMS documentation included on the Pro Tools CD-ROM. To configure your PRE in OMS: Powering Up Pro Tools System In order for Pro Tools to communicate properly with audio interfaces and other peripherals, it is important that you start up and shut down your system in the following order: Power up your system in this order: 1 Turn on your Pro Tools hard drives. [. . . ] This display can be toggled with the SHOW VALUES button. Values are also shown when the encoder is adjusted. The REMOTE MIC PRE button enables this mode (or returns Control|24 to its previous operation mode). When enabled, the REMOTE MIC PRE LED is lit, and the Channel Bar Display updates with the following message: "MIC PRE. " To set input gain using Channel-Wide Gain Control mode: 1 Press REMOTE MIC PRE. [. . . ]
