Can the X75 be used as a “mini-master control switcher?”
No, the
X75
Multiple Path Converter and Frame Sync is not a “mini-master control switcher.” The
video goes to black for four frames when switching between SDTV and HDTV signals. This is not a
problem for a simple switcher or a backup switcher to a master control. SDTV to/from SDTV
switching and HDTV to/from HDTV switching is OK. The audio may not be quiet during switching,
especially if the audio levels are different.
What is M-PATH?
M-PATH is Multiple Path Processing. An
X75HD
has the capability of up to four simultaneous paths
of processing with an analog video input option installed. For example, the
X75HD
can provide up
and down or cross and down conversions at the same time. The
X75SD
has the capability of up to
three paths of processing with an analog video input option installed. For example, the
X75SD
can
provide dual SDI paths or analog to digital and digital to analog at the same time.
There are two genlock connectors. How are they implemented?
The two input genlock connectors can set for looping (one reference) or for two separate reference
inputs. If the two genlock inputs are used (e.g., tri-level and color black), you can select which one
you wish to use.
What type of test signals will available with the X75?
A complement of SDTV signals can be provided on the analog and digital SDTV outputs. The
X75HD
adds a complement of HDTV test signals on the HDTV outputs. If the audio option is used,
there are four selectable test tones for the embedded, AES and analog outputs.
Are there filters for the fans?
No. Filters clog up, airflow is reduced, internal temperature goes up, and the unit may stop working
(and you don’t have to have someone on the night shift spending all of their time vacuuming out and
cleaning filters).
Are DPS-575s compatible with X75s?
Yes, video and audio signals can be passed from unit to unit — providing that standards are observed.
For control purposes, a proper Ethernet connection allows communications between units.
