1) The Power Switch LED
indcates that the Rosetta 800 is
receiving a proper AC input, and
is in Standby mode. The LED goes out
when the Rosetta 800 is powered on.
2) The 176.4 and 192 values
cannot be selected on the
96kHz version of the Rosetta
800. The unit may be upgraded to
192kHz operation at any time.
3) A different AES format may be
selected for each sample rate
range.
4) When clocking to an AES
input (i.e SYNC is set to AES),
the format must be specified by
selecting a SYNC value of either AES or
AES + DW.
Advanced Settings:
Advanced settings are accessed by pressing and holding one front panel
button while using a second button to modify values. These advanced
settings are described in light gray boxes after the primary description of
each button.
1)POWER SWITCH – The Power Switch may be configured to operate in
the manner best suited to the installation of the unit. For example, if the
Rosetta 800 is installed in a rack with a Master power switch, the unit's
power switch may be configured appropriately. Please see the section of this
manual entitled "Internal Adjustments" for details.
2) SAMPLE RATE – This parameter modifies operation in two distinct ways
according to the value selected:
1) When any of the values 44.1-192 are selected, the unit derives its clock
from an internal crystal and runs at the selected sample rate.
2) When EXT is selected, the unit derives its clock from the source
selected by the SYNC parameter; the 44.1-192 LEDs now display the
sample rate of the selected source.

SAMPLE RATE Advanced settings:

When running at a sample rate between 88.2-192 kHz, the Rosetta 800's
AES I/O may be configured for Single wire or Double wire operation.
1) Select the desired SAMPLE RATE value.
2) Press and hold SAMPLE RATE to determine the current AES format, as
indicated by the three DW LEDs on the front panel; if DW is on, the AES
format is Double wire; if DW is off, the format is Single wire.
3) While pressing the SAMPLE RATE button, press the SYNC button to
toggle DW (Double Wire) on or
