RENT / TRILOGY MASTER MIND
Designed to complement the Mentor and Mentor Plus units, The
Mastermind changeover actively monitors the condition of both
analogue and digital reference and test signals. Option boards
may be used to configure the unit to individual requirements. As
standard the unit monitors one pair of main and reserve black
burst inputs and includes changeover of these signals plus relay
changeover of three pairs of other signals.
Option modules include:
330-01-00 Black burst monitor and changeover board
330-02-00 SDI monitor and changeover board (Alsopasses embedded audio)
330-06-00 AES audio monitor and changeover board
330-03-00 Three pair relay changeover board
