Audio Monitoring
A powerful monitoring bus provides audio monitoring at the card-edge headphone socket
and rear connector.
TANDEM-110 audio monitoring
A fully selectable analogue monitoring output is fed to a miniature stereo jack socket at
the card edge. Select any valid stereo signal to be monitored with the monitoring drop-
down list.
The RM04 and frame rear connector can also receive the same user-selectable analogue
monitoring signal as the headphone socket. This output may be switched on or off using
the ‘Monitor bus on’ check box in the Preset menu.
SDI Crystal control
The embedder SDI crystal PLL may be left to free run or locked and inserted into either
to SDI 1 or SDI 2.
The SDI signal accumulates an ever-increasing amount of jitter as it progresses through
an SDI installation, and as it passes through most equipment in its path. To minimise this
effect, TANDEM has an SDI crystal controlled re-clocker. This is a form of ‘Time Base
Corrector' which sets the output SDI signal to the same mean frequency as the input, but
re-clocked by a crystal controlled Phase Locked Loop [PLL], to produce extremely low
jitter in the SDI output.
