Getting Started

Owner's

Once you’ve unpacked your new

Digital X Bus, you’ll want to posi-

tion it where you can sit comfort-

ably and reach the touchscreens and controls, and have relatively

easy access to the rear panel, in case you need to make any changes to the connections. Typically, once you’ve set it up and made the connections, you won’t have to make any changes unless you change your external equipment.

Connections

The Digital X Bus comes with a Mix Out card (con- trol room card) and a Sync card already installed in the card cage in the rear panel. There are also connections for a USB mouse/keyboard, footswitches, MIDI and other fun stuff. While not required to operate the Digital X Bus, the mouse and keyboard can be handy for quickly entering data or when clicking is easier than touching (the touchscreen).

Depending on your particular configuration and re- quirements, we have a variety of analog or digital I/O cards that you can install in the card cage to suit your application. Here’s a quick run-down of what we offer:

I/O Cards

1. MIC/LINE 4 CARD

This card has four female XLR balanced microphone inputs, and four 1/4" TRS balanced/unbalanced line-level inputs, for a total of eight analog inputs. Note that this card does not provide any outputs.

Each mic input provides an individual phantom switch (+48 VDC), and a digitally controlled input trim. All these controls are found in the I/O Configu- ration window.

Each line input on the Mic/Line 4 card has a corresponding –10 dBv/+4 dBu jumper (J10-J13) on the card that determines the input level reference point. These jumpers come pre-installed from the factory at a +4 dBu input level. However, if you have unbalanced or low line-level sources, you may choose to remove these jumpers and set the input reference to –10 dBv to better use the headroom of the mixer. You can physically see these jumpers on the printed circuit board of the card itself, and they can be removed simply by pulling them off the card.

2. MIC/LINE 8 CARD

The Mic/Line 8 card has two female DB25 con- nectors, one for inputs and one for outputs. The input connector accepts eight balanced analog inputs that can be switched between mic- or line-level inputs. As with the Mic/Line 4 card, each mic input provides a phantom power switch and a digitally controlled input trim.

The output connector provides eight balanced line- level outputs. These DB25 connectors use the TAS- CAM standard pinout for analog signal connections (the same standard used on the analog cards for the Mackie D8B and Hard Disk Recorder). If you are connecting these to another device using the same DB25 standard, you can use a DB25-to-DB25 audio cable. Otherwise, you will need to use DB25 cables that breakout to XLR, 1/4" TRS, or TT connectors.
