Connecting The Rpx400 To The Computer; Rpx400 Recording Setup - DigiTech RPX400 User Manual

Connecting the RPx400 to the Computer

The RPx400 comes equipped with a USB cable that is to be connected to your computer whenever your
will be recording or using the X-Edit Editor/Librarian. We recommend that you only use the USB cable
that is shipped with the RPx400 since it has been tested and approved for this specific use. To connect
the RPx400 to the computer, follow these steps:
1. Begin with the power disconnected from the RPx400.
2. Plug the small end of the USB cable in to the USB jack on the back of the RPx400.
3. Plug the large flat end of the USB cable into an available USB port on your computer.
4. Connect power to the RPx400.

RPx400 Recording Setup

The RPx400 has several different input / output configurations called Setups offering a wide variety of
recording possibilities. These are selected using the USB 1-2 Source and USB 3-4 Source knobs in
the RPx400's effect matrix. For a given recording session, you may want to record guitar with effects, dry
guitar, vocal, line inputs, a combination of these, or even re-amp your dry guitar tracks back through the
RPx400. Up to 4 channels of audio can be sent simultaneously to the computer and the knobs in the
SETUP row select how and which audio signals are routed up the USB connection. Each USB Source
routes a pair of signals to the computer. The following sections outlines how these signals are routed:
