USING THE RDI-8 AS A DI BOX (DIRECT INJECTION UNIT)
Connect the signal you would like to convert from unbalanced to balanced to the RDI-8 via a 1/4” unbalanced plug to one of the chan-
nel LINE INPUTS (1) on the front panel of the unit. Connect an XLR balanced cable to the corresponding channel OUTPUT (8) on the
rear of the RDI-8 and connect to your chosen destination. If the input signal strength is too “hot” (high) you can depress the 20dB PAD
(6) switch to adjust to a more appropriate level. If there is a ground loop hum you can remove it by depressing the GROUND LIFT (5)
switch.
USING THE RDI-8 AS A LINE MIXER
You can mix volume & pan of all input signals simultaneously to both stereo pairs of RCA connections on the rear of the RDI-8: the
MASTER (13) and LINE (14) outputs. This enables use of the unit as a fully functional line mixer. This can be very handy for many ap-
plications, both live and in the studio. Just connect either or both the stereo MASTER (13) or LINE (14) outputs on the rear to your
chosen destination(s), such as a monitor amplifier, and adjust the individual VOLUME (3) and PAN (4) controls for each individual
channel on the front of the RDI-8 to suit your needs. A MASTER VOLUME (7) control is provided on the front panel, in addition to the
individual controls, and adjusts only the MASTER (13) output. Adjust as necessary.
USING THE RDI-8 PARALLEL CHANNEL LINE OUTPUT
A unbalanced parallel LINK OUTPUT (2) is provided on the front panel next to each LINE INPUT (1) jack. This is useful for routing a
direct link out, in addition to the balanced XLR OUTPUT (8) on the rear panel (for example, if you would like to monitor a specific input
locally while sending a XLR balanced direct output to another source without affecting the line mixer signal).
