Before connecting audio, determine whether your audio
system is unbalanced or balanced. Connect an audio
device, such as powered speakers, to the rear panel stereo
audio output connector for balanced or unbalanced audio
output. Following the wiring guide (figure 2-17), insert
the wires into the appropriate openings in the captive
screw connector. Tighten the screws on top to fasten
the wires, then insert the wired audio connector into
the audio output connector on the interface rear panel.
Wiring the audio incorrectly can damage the audio
output circuits.

Connect the sleeve(s) to ground (GND).
Connecting the sleeve(s) to a negative (-) terminal
will damage audio output circuits.
Setting the DIP switches
DIP switches on the rear panel of the RGB 130xi, and RGB 134xi,
and on the front and rear panels of the RGB 160xi and RGB
164xi, are used to configure the interface. The switches can be
either the rocking type or the sliding type.
To set the rocking-type DIP switches, use a tweeker or small
screwdriver to depress the appropriate end of each switch.
To set the sliding-type DIP switches, use a tweeker or small
screwdriver to slide the switch to the on/closed or off/
open position.
All models
The RGB 130xi, RGB 134xi, RGB 160xi, and RGB 164xi have four
DIP switches on the rear panel to control:
•
Sync on green output
•
Digital display sync processing
•
Serration pulses
•
75-ohm input termination (RGB 130xi and RGB 134xi
only, spare on RGB 160xi and RGB 160xi)
SOG (sync on green output)
On — If this switch is set to On, the interface outputs a
composite sync signal on top of the green video
signal via the G output connector (RGsB).
Off — If the SOG feature is set to Off, output is RGBS or
RGBHV, depending on how the interface and
projector are cabled.
DDSP™ (digital display sync processing)
On — If this switch is set to On, the interface does not
perform sync processing. This may be necessary
for digital display devices, such as LCD (liquid
crystal display), DLP (digital light processor) and
plasma displays.
