Front Panel Setup
There are a number of parameters that can be set by front-panel Setup commands. In normal operation the
Up/Down arrows select channels, and the Left/Right arrows adjust volume.

 Pressing Setup ends menu item editing or exits the front-panel setup mode
Front Panel Menus
Menu Parameters
Basic Settings In most cases, the menus below will work for most displays at sites.
Video Input This selects the appropriate input:
- SDI (autosenses 1080i, 720p, 480i)
- YPbPr (1080i, 720p, 480p, 480i)
- Video (automatically uses 480i)
- S-Video (automatically uses 480i)
HD Format Component SDI auto-senses; Video and S-Video inputs are automatically set to
480i. Selection is locked unless there is no input.
- 1080i - 480p
- 720p - 480i
Channel XXX
Left/Right steps through channel numbers (use Left to access high channels)
Cable Format Standard cable frequencies (default)
HRC – same as Standard, channels 5 and 6 slightly different
IRC – All channel frequencies are different than the standard cable setting
RF Level dB Sets the output level of the RF output, in dBmV
- 29 (default) -17
- 25 -13
- 21 - 9
Audio Input Sets audio input for currently selected input (SDI, Component, and Video have separate
audio-follow memory)
SDI G1 – Embedded audio (normal stereo)
SDI G2 – Embedded audio
SDI G3 – Embedded audio
SDI G4 – Embedded audio
Digi (Digital) Optical
Digi Coax
Analog (default)
No Vid Color Displays a color background with there is no video input, or the resolution doesn’t match the
QMOD settings.
- Orange
- Purple (default)
- Green
QAM Type Today, most displays are set to tune 256 QAM. If a site has some very old displays, they
might only be able to tune in channels set to 64 QAM. Continuous Wave is often used to test
the channel with a meter.
- 64
- 256 (default)
- CW (Continuous Wave)
