BNC -
(BNC Button). In PCM mode, this controls the operation of the BNC button.
Input Configures the BNC input connectors as a data
input. Press the BNC button to select it.
RefCl Configures the BNC word clock in (Clk In)
connector as a reference clock input. Press the
BNC button to sync the unit to the Word clock
while taking data from one or more of the AES
inputs. The BNC LED will light, in addition to the
LED(s) for the data source. Press the BNC button
again to sync to the data input instead.
This mode of operation enable the unit to sync to one clock source and rapidly
switch between other synchronous sources without going through a PLL locking
sequence. It might be used, for example, in A/B comparisons or in locking to a
house sync, just taking data from AES feeds.
If the unit is already locked to SDIF or DSD, the RefCl option is disabled.
BNC O -
(BNC Output). In PCM mode, this sets the format of the BNC Out connector
(Clk Out).
SDIF Sends out SDIF Word Clock on the Clk Out
connector. The unit must be locked to generate an
output.
AES Sends out AES3 coded data at TTL levels, at up to
96 kS/s on the Clk Out connector. This works
when the unit is locked to Single AES, SDIF or
BNC - AES input.
Panel -
(Panel Control). Sets the operation of the Phase and De-Emphasis buttons.
Phase Sets the two buttons to their standard functions.
Vol The two buttons act as a digital volume control.
Phase reduces the Volume in 0.1dB steps, while
De-Emphasis increases the Volume. The change
accelerates if a button is held down. The range is
0dB to –20dB.
