8.2 Menu Operation
8.2.1 SR / Format -
sets the sample / DSD rate of the AD conversion. Variety
of settings shown in this menu depends on the mode selected in the „Mode”
menu.
When „ADC” (stand-alone) mode is selected following settings are available:
•
PCM: 44.1, 48, 88.2, 96, 176.4, 192, 352.8, 384 kHz
•
DSD: x64, x128, x256
Analog input signal is present on all digital outputs at the same time and device can be clocked to
internal,
precise clock or an external source via WordClock.
When „PC” (personal computer) mode is selected following settings are available:
•
Ntv (native) – use this setting if you need to record DSD natively. This setting is also recommended
for PCM recordings – when device operates as typical playback / recording interface. Device
follows sample rate choosen in recording software and the rate is shown on display if Brooklyn
ADC is locked properly.
•
DoP (DSD over PCM) – use this setting if you need to record DSD via DoP.
•
QdoP – use this setting if you need to record DSD x256 via DoP.
The Brooklyn ADC is capable to record true (not floating point) 32bit files.
8.2.2 Clock Source
There is only one master device in digital world. The others have to operate as a slave. That is
why external digital devices such as digital speaker systems, preamps, synthesizers, recorders etc.
have to be also configured properly. Otherwise clicks, drops, distortions might appear in the final
signal. Following sync options are available:
• INT
(Internal) / USB / outcoming signal is synced to the converter’s ultra-low jitter internal
crystal oscillator. This choice assures the best ADC performance and is superior to any (even
Atomic) clock supplied from outside because of its close proximity to ADC clocking chipset. The
ADC operates as a master device. WordClock OUT transmits master clock signal
• WCK
(Word Clock) / available for USB, AES, SPDIF, Toslink, SDIF / the ADC can operate as a
master or slave device.
Word Clock Physical connections examples:
A. The
Brooklyn ADC is a master
and the external device is a slave: Brooklyn ADC WCK OUT -> external device WCK IN
B. The
Brooklyn ADC is a slave
and the external device is a master: Brooklyn ADC WCK IN -> external device WCK OUT
