APOGEE ELECTRONICS

CONNECTING POWER

The Rosetta 800 accepts an AC input of 100 to 240v AC at a frequency of 50
to 60 Hz. Thus, the unit may be connected to virtually any AC power outlet
found worldwide without concern for voltage settings or fuse ratings.

RESET

To reset the Rosetta 800, power up the unit while pressing the SAMPLE RATE
button. This provides a quick method to return to factory default settings when
exploring the unit’s functionality and capabilities.

QUICKSTART

To get started using the Rosetta 800 quickly, please follow these steps:

1) Connect the AC input, and press the POWER button.

2) Connect an analog source to the ANALOG INs, connect a digital device to
the appropriate digital I/O (ADAT is used in this example), and connect the
ANALOG OUTs to a monitoring system.

3) Set SAMPLE RATE to 44.1, set SOURCE TO DIGITAL OUTS to ANALOG,
and set SOURCE TO ANALOG OUTS to ADAT, as shown above.

SIGNAL FLOW

The Rosetta 800 offers the possibility to configure two independent signal
paths through the unit. In most cases, the first signal path is configured as
an A/D stage before a digital recording device while the second signal path
is configured as a D/A stage after the recording device.

For example, when the Rosetta 800 is configured to the Quickstart setting
noted above, the following two signal paths are present: 1) the analog
sources to be recorded are connected to the Rosetta analog inputs,
converted to digital and routed to all Rosetta digital outputs including the
ADAT output, connected to an ADAT recording device input; 2) the ADAT
device output is connected to the Rosetta ADAT input, which is converted to
analog and routed to the Rosetta analog outputs, connected to a monitoring
system. Other configuration examples are given in the back of this manual.

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:

APOGEE ELECTRONICS

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.

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.

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

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.

3

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 off.

APOGEE ELECTRONICS

3) SYNC – When SAMPLE RATE is set to EXT, the SYNC parameter
determines the source of the unit’s clock.

• ADAT – clock is derived from the ADAT input 1-8 with a resultant sample
rate in the 44.1-48kHz range.

• ADAT + S/MUX – clock is derived from S/MUX Input 1-4 with a resultant
sample rate in the 88.2-96kHz range.

• OPTION – clock is derived from the Option Card input.

5

• AES – the AES input is scanned and clock is derived from the first valid
AES signal found. The signal is treated as Single wire format.

6

• AES + DW - the AES input is scanned and clock is derived from the first
valid AES signal found. The signal is treated as Double wire format.

• WC – clock is derived from the Word Clock In connector.

SYNC Advanced settings:
The Rosetta 800 may be configured to accommodate digital systems whose
word clock signals run at a multiple of the sample rate frequency.

1) To configure the Rosetta 800 to sync to a word clock input of one
frequency while running at a sample rate whose frequency is a multiple of the
word clock:

1) Connect the word clock signal to the Word Clock In and set SYNC
to WC.

2) Press and hold the SYNC button to determine the current “target”
sample rate range.

3) While pressing the SYNC button, press the SAMPLE RATE button
to toggle through the possible “target” ranges. For example, to
sync the Rosetta 800 to a 44.1kHz Word Clock input while running
at 88.2kHz, maintain the SYNC button depressed while pressing
the SAMPLE RATE button the until both the 88.2 and 96 LEDs
light.

7 8

5) If no Option card is present,
the Option value may not be
selected.

6) When clocking to an AES
input, the AES format must be

specified by selecting a SYNC
value of either AES or AES + DW, not via
the SAMPLE RATE Advanced settings.

7) The Word Clock Out will
always be the same frequency
as the Word Clock In.

8) A different Word Clock
configuration may be set for
each sample rate range.

2) To configure the Rosetta 800 to sync to another source (internally or other
SYNC values besides WC) and output a Word Clock signal whose frequency
is a multiple of the sample rate frequency:

1) Set the unit to the desired clock source and sample rate

2) Press and hold the SYNC button to determine the current Word

button to toggle through the possible ranges. For example, to run
the Rosetta 800 at an 88.2kHz sample rate while outputting a

44.1kHz word clock, set the SAMPLE RATE to 88.2, maintain the
SYNC button depressed while pressing the SAMPLE RATE button
until both 44.1 and 48 LEDs light.

APOGEE ELECTRONICS

9) The clock circuitry of a
typical D-to-A converter must

be designed as a compromise
between the ability to attenuate input
signal jitter and the ability to accept any
bitstream, regardless of it’s stability. The
more the clock is allowed to track timing
variations of the input, the more jitter
remains in the clock at the conversion
stage, with the degradation of conversion
quality as a result. The ROSETTA
800’s Dual Stage Clock overcomes
this compromise by employing one
clock stage to accept the bitstream
and store bits in a buffer, and a second
stage to clock bits out of the buffer to
the conversion stage. The first stage is
optimized to track timing variations of the
input, while the second stage is optimized
to attenuate jitter and ensure that
conversion takes place with the lowest
jitter clock possible.

10) When the Rosetta 800 is
running at the 176.4 – 192

kHz sample rate range, neither
ADAT nor ADAT + S/MUX may be
selected.

4) LOCK - These LEDs indicate the Lock status of the Rosetta 800’s dual stage
clock. Two levels of lock precision are displayed, Wide and Narrow.

5) SOURCE TO DIGITAL OUTS – This parameter configures the first of two
available signal paths by selecting the input source(s) routed to ALL digital
outputs. A total of eight channels may be routed, either entirely from one source
or from one digital source and the Analog source. To select a digital source and
the Analog source simultaneously, toggle through the entire set of possible values
until both desired SOURCE TO DIGITAL OUTS values are lit. Assignment of each
of the 8 channels to a digital or analog source is accomplished (by pairs) with the
Advanced settings noted below:

SOURCE TO DIGITAL OUTS Advanced settings:

When two sources have been selected, the following Advanced settings
become available:

• To display current routing:

1) Press and hold the SOURCE TO DIGITAL OUTS button to
display the current configuration of analog and digital sources as
indicated by the DIGITAL OUT LEDs. If the DIGITAL OUT LED is
on, the source for the corresponding channel pair is the Analog
input; if the DIGITAL OUT LED is off, the source is the selected
digital input. For example, in FIGURE 1, channels 1-2 and 7-8 are
set to the Analog source, while channels 3-4 and 5-6 are set to the
ADAT source.

6) SOFT LIMIT – This button engages Soft Limit, Apogee’s proprietary transient

limiting circuitry, on all 8 Analog inputs. Soft Limit transparently rounds transient
spikes in a manner similar to analog tape, allowing several more dB of signal to be
recorded onto the digital medium.

7) OUTPUT RESOLUTION – This button engages UV22HR, Apogee’s proprietary
bit-resolution reduction algorithm, on all digital outputs. UV22HR should be applied
when 16-bit digital devices are connected to the Rosetta 800’s Digital outputs, such
as DAT recorders or CD burners. By adding an algorithmically generated, inaudible
concentration of energy at around 22kHz, UV22HR preserves 24-bit resolution in a
16-bit digital signal.

8) SIGNAL LEDs

1) A/D OVER – These red LEDs indicate the occurrence of digital OVERs
(defined as 3 consecutive samples at full scale) in the A/D converter section.

2) DIGITAL OUT – These LEDs indicate the digital level of the source(s) routed
to the digital outputs.

3) ANALOG OUT – These LEDs indicate the digital level of the source(s) routed
to the analog outputs.

9) SOURCE TO ANALOG OUT – This parameter configures the second
available signal path by selecting the input source(s) routed to the analog outputs.
A total of eight channels may be routed, either entirely from one source or from
one digital source and the analog source. To select a digital source and the
Analog source simultaneously, toggle through the entire set of possible values
until both desired SOURCE TO ANALOG OUT values are lit. Assignment of each
of the 8 channels to a digital or analog source is accomplished (by pairs) with the
Advanced settings listed below:

11) A blinking digital source
LED indicates that the
selected source is not

synchronous with the unit’s clock source.

12) The S/MUX and DW LEDs
located in the SOURCE TO
DIGITAL OUTS value list are

indicators only and cannot be selected.

13) OUTPUT RESOLUTION
can be set to 16-Bit UV22HR
only when SAMPLE RATE is

set to the 44.1-48 kHz range.

SOURCE TO ANALOG OUT Advanced settings:

When two sources have been selected, the following Advanced settings become
available:

• To display current routing:

1) Press and hold the SOURCE TO ANALOG OUT button to display the current
configuration of analog and digital sources as indicated by the ANALOG
OUT LEDs. If the ANALOG OUT LED is on, the source for the corresponding
channel pair is the Analog input; if the ANALOG OUT LED is off, the source is
the selected digital input.

• To modify routing:

1) While pressing the SOURCE TO ANALOG OUT button depressed, press the
SOFT LIMIT button to select the pair of channels to be modified; the selected
pair is indicated by the flashing A/D OVER LEDs.

Internal Adjustments

ANALOG INPUT/OUTPUT CALIBRATION

Calibration levels for the Analog Inputs and Outputs are set with internal jumpers. A “block” of 6 jumpers offers 3
level settings for each input and output channel. The locations of these jumpers are indicated in FIGURE 3.

APOGEE ELECTRONICS

FIGURE 3

FIGURE 4 depicts the reference
analog and digital levels obtained
when applying a shunt to each
pair of jumpers. For example,
when a shunt is applied to the
middle pair of each input and
output “block”, a +4 dBu analog
input results in a –16 dBFs digital
output, while a –16dBFs digital
input results in a +4 dBu analog
output.

POWER SWITCH CALIBRATION

JUMPER P3

(as seen from front) DESCRIPTION

When AC power is applied to the input, the unit does not
power up immediately; to power on the unit,the POWER
button must be pressed.

When AC power is applied to the input, Rosetta 800 powers
on immediately; nevertheless, the POWER switch is
functional.
