Display
The equipment draws nominal non-operating power from
the AC outlet with its POWER switch in the OFF position.
WORD
Use this button to switch between word sync modes. A mode
indicator lights up to show the current mode (blue indicators
showing normal modes, and a purple indicator showing the
4% down mode). The indicator blinks when no usable word
sync signal is detected. No indicator lights when word sync is
not being used.
OUT
Lets the unit internally generate and send out Word Clock
so the unit acts as a master.
IN
This mode provides a stable sync operation with most
general external clocks. There are occasions when sync is
not achieved depending on the output accuracy of the
devices in use. This is because the word clock input
frequency range of this unit is set to as narrow as ±15ppm,
a requirement in order to achieve a sync of high accuracy.
Rb IN
This is a mode designed for external clocks of a higher
degree of precision like a rubidium clock generator. Select
this mode when this unit is connected to the ESOTERIC G-0s.
Keep in mind that it will take time before the sync is
achieved in this mode. This mode requires an even narrow
bandwidth of accuracy to lock.
Switch the mode to IN when “WRD UNLOCK” or “WRD
ERROR!” is shown.
Off (tuned off)
The unit does not use any word sync.
B
4% down mode
Pressing and holding this button for more than 3 seconds
switches the unit back and forth between 4% down and
normal modes.
<
Selecting IN or Rb IN modes achieves sync by using an
external clock as master. When in those modes, the word
clock fed into the WORD SYNC IN terminal is directly sent out
through the WORD SYNC OUT terminal.
<
This unit readily accepts a maximum 196 kHz clock and
automatically switches itself to the incoming signal.
<
When selecting IN or Rb IN modes, the corresponding
indicator blinks and searches for an external clock. When the
unit detects a clock and locks to it, the indicator lights steadily
(blue) to show that the unit is ready for play.
<
Make connections to the WORD SYNC terminals prior to
powering on the unit.
