Miranda Densite ENC-1103 Manual To Installation And Operation

DESCRIPTION
The ENC-1103 is a high-quality encoder with 12-bit
conversion allowing operators to convert a SDI signal to
Composite, CAV or RGB. The composite outputs can be
NTSC, PAL or PAL-M and the component outputs can be
SMPTE, BETACAM or GBR formats. With its on-board
Genlock and Video Proc-Amp, the card provides flexible
system integration. An optional Frame Sync provides infinite
timing adjustment relative to an external reference. When
embedded audio is required to be separated into discrete
channels, the built-in audio demux (24-bit) allows up to 8
channels (2 groups) to be passed to an audio card. New
technology includes thumbnail generation and an optional
Waveform/Vectorscope over IP of the output signal which
allows operators to control and see the changes made to
the signal.
This card operates with the MSB-1121 Monitoring Switching
Bridge which allows the output of any module in the Densité
frame to be monitored.
