Clock Settings
The 'CLOCK' control interface consists of a
'CLOCK SOURCE' button, a 'Sample Rate'
button. Each button has a corresponding LED
display.
The ADC16 can operate from its internal
clock, or it can lock to a variety of external
clock sources. Valid clock signals include
Word Clock, Super Clock, AES, SPDIF, and
the optional 'DAW' interface card.
Clock Source
'Clock Source' Button
The 'CLOCK SOURCE' button is a 'press-and-
hold' switch. This means that the user must
hold in the button for one second before the
clock source changes.
The 'press-and-hold'
action prevents accidental changes.
'CLOCK SOURCE' LED Display
The 'CLOCK SOURCE' display indicates which
input is acting as a clock reference for the
ADC16. The indicators are as follows:
DAW
– On = clock is locked to the
optional interface card
AES
– On = clock is locked to the
AES/EBU input via DB-25
WC
– On = clock is locked to the WC
input via BNC
INT
– On = clock reference is the
ADC16's internal clock
Clock Sample Rate
The 'SAMPLE RATE' control interface consists
of a 'SAMPLE RATE' button and LED display.
The 'SAMPLE RATE' Button
The 'SAMPLE RATE' button sets the sample
rate when the ADC16 is in the 'INT' clock-
source mode. This button is only active when
the 'INT' LED is on.
To change the internal clock sample rate,
press and hold the 'SAMPLE RATE' button.
The 'SAMPLE RATE' button must be held for 1
second to change to the next rate.
The
'press-and-hold' action prevents accidental
changes.
'SAMPLE RATE' LED Display
44.1kHz
48 kHz
88.2 kHz
96 kHz
176.4 kHz
192 kHz
The 'SAMPLE RATE' LED display always
indicates the sample rate at which the ADC16
is operating.
