About Secondary Parameters - Most front panel buttons control both a primary and secondary parameter; as indicated by the two labels under each button. Secondary parameters are usually accessed by pressing and holding the corresponding button.

1) Power Switch – The POWER Switch may be configured to operate in two distinct modes : 1) the unit powers up immediately when power is applied to the AC input (for example, when the unit is installed in a rack with a Master power switch); 2) the POWER switch must be pressed to turn the unit on. See page 10 for POWER switch configuration details.

The LED adjacent to the POWER switch indicates that the unit is receiving a proper AC input, and is in

Standby mode. The LED extinguishes when the unit is powered on.

2) SAMPLE RATE - This parameter determines the sample rate of the unit, either by selecting an internally clocked rate between 44.1kHz and 192kHz or by locking to an EXTernal clock source as selected by the

SYNC parameter. When EXT is selected, the 44.1-192 LEDs display the sample rate of the external source.

3) AES FMT (AES Format)– At sample rates between 88.2 and 192 kHz, the Rosetta 200’s AES I/O may be configured for either Single or Double wire operation.

To determine the current AES format, press and hold SAMPLE RATE; Double wire format is indicated by the illumination of the 3 DW LEDs above the SYNC and SOURCE buttons.

To change the AES format, first press and hold SAMPLE RATE and then press SYNC to toggle DW on or off.

When clocking to the AES input, the AES format is determined by the format of the SYNC value selected

(either AES or AES + DW).

4) Optical Output Format – At sample rates between 44.1 and 96 kHz, the Optical Output format may be set to either ADAT (S/MUX) or S/PDIF.

To determine the current Optical Output format, press and hold SAMPLE RATE; the format is indicated by the optical format LED lit above the SYNC and SOURCE buttons.

To change the Optical format, first press and hold SAMPLE RATE and then press SOURCE (to Digital

Outputs) to toggle between ADAT (S/MUX) and S/P OPT.

By selecting one Optical format as a SOURCE (to Digital Outputs) and setting Optical Output to the other format, it’s possible to convert between ADAT (S/MUX) and S/PDIF Optical formats.

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

S/P COAX – clock is derived from the S/PDIF In coaxial connector

S/P OPT – clock is derived from the Optical In connector; the input signal is assumed to be S/PDIF format.

ADAT – clock is derived from the Optical In connector; the input signal is assumed to be ADAT format, thus the resultant sample rate will be in the 44.1-48kHz range.

ADAT + S/MUX – clock is derived from the Optical In connector; the input signal is assumed to be S/MUX format, thus the resultant sample rate will be in the 88.2-96kHz range.

OPTION – clock is derived from the connected option card input (e.g. X-FireWire)

AES – clock is derived from the AES In 1 connector.

AES + DW – clock is derived from the AES 1 In connector; the input signal is assumed to be Double wide format, thus the resultant sample rate will be in the 88.2-192kHz range.

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

6) WC I/O (Word Clock I/O Ratio) – This parameter determines the ratio between the Word Clock Input/Output frequency and the unit’s sample rate.

•To set the ratio between a Word Clock Input and the unit sample rate (when locked to WC):

1 Connect a word clock signal to the Word Clock In, set SAMPLE RATE to EXT, and set SYNC to WC.

Verify that both the Wide and Narrow Lock LEDs light.

2 While holding down the SYNC button, press the SAMPLE RATE button to toggle to the desired sample rate range.

• To set the ratio between the Word Clock Output frequency and the unit’s sample rate (when locked to all other internal or external clock sources).

1 Select the desired sample rate or external clock source.

2 While holding down the SYNC button, press the SAMPLE RATE button to toggle to the desired word clock output frequency range.

7) LOCK – These LEDs indicate the Lock status of the Rosetta 200’s clock. Two levels of lock precision are displayed, Wide and Narrow. When both Wide and Narrow are lit, the Rosetta 200 has locked to the selected

CLOCK SOURCE in such a way as to ensure the highest quality conversion. If only the Wide LED lights, the stability of the clock source is questionable, and the source should be verified.

8) SOURCE (to Digital Outputs) – This parameter selects the input source that is routed to ALL digital outputs. To employ the Rosetta 200’s A/D converters, set this parameter to Analog.

9) SRC (Sample Rate Conversion) – When a digital source has been selected, press and hold SOURCE (to

Digital Outputs) to engage SRC. Please see AUTO SRC (below) for more detailed information..

10) CLEAR - This button clears the meter’s OUCH (OVER) LEDs

11) SOFT LIMIT – Press and hold CLEAR to engage SOFT LIMIT on both analog inputs. Soft Limit is an analog process that rounds transient peaks –4 dBFs and above with attack and release times that may be considered instantaneous. As with any peak reduction device working at such fast time constants, Soft Limit is most effective with signals whose peak information is greater than its average (or RMS) information, such as drums, plucked instruments and dynamic mixes. Soft Limit may not be the appropriate choice for limiting signals whose crest factor (peak to RMS ratio) is low, such as bass or organ.

12) CODA – The CODA Audio Finishing Module is comprised of three processes : SRC (Sample Rate

Conversion), UV22HR and APTOMIZER.

13) PROCESS – This parameter toggles AUTO SRC on and off and sets digital output resolution to 24 or 16bit/UV22HR

AUTO SRC (Sample Rate Conversion) – When AUTO SRC is engaged, sample rate conversion is automatically applied to digital inputs when needed. If a selected digital input is detected to be nonsynchronous with the unit’s clock, sample rate conversion is automatically applied to the input and the corresponding SRC LED lights.

24-BIT/16-BIT/UV22HR – When the unit sample rate is set to a range of 44.1-48k, the bit resolution of all digital outputs may be set to either 24-Bit or 16-Bit/UV22HR. When 16-Bit/UV22HR is selected, Apogee’s proprietary dither signal, UV22HR, is employed to encode 24-bit resolution in a 16-bit signal.

Please note: AUTO SRC will be available in a future software upgrade.

Sample Rate Conversion - As the number of digital audio sample rates increases, the necessity for high quality conversion between these rates grows. For the first time on an Apogee product, sample rate conversion is offered on the Rosetta 200. To employ sample rate conversion:

1 Connect the source to one of the Rosetta 200’s digital inputs and set SOURCE (to Digital Outputs) to the appropriate setting.

2 Connect the destination to a Rosetta 200 digital output.

3 Select the desired output sample rate

4 Press and hold the SOURCE (to Digital Outputs) button until the SRC LED lights.

5 Keep in mind that SRC may be applied to one digital input only.

To get a better sense of SRC’s function, here are a few examples where it might be employed:

96k/24 bit to CD (44.1kHz 16 bit) – Perhaps the most common application of SRC is the conversion of high sample rate audio to the Compact Disc rate of 44.1kHz. By using SRC in conjunction with Apogee’s UV22 bit resolution reduction algorithm, CD transfers retain the quality and resolution of the original high sample rate/ bit depth audio. Follow these steps to convert a 96k, 24 bit AES digital input to a 44.1kHz, 16 bit digital output.

1 Connect the 96kHz signal to AES Input 1, connect the appropriate digital output to the destination machine.

2 Set SAMPLE RATE to 44.1

3 Set SOURCE (to Digital Outputs) to AES; set SOURCE (to Analog Outputs) to AES to monitor the converted signa via the analog outputs.

4 Press and Hold SOURCE (to Digital Outputs) and verify that the SRC LED next to each SOURCE button is lit

5 Press PROCESS to select 16 bit/UV22HR

6 The signal routed to all digital outputs is now 44.1kHz 16-bit.

Monitoring or transferring from non-synchronous digital sources quickly – To monitor or transfer from nonsynchronous digital sources such as DAT machines, CD players and synth modules with digital outputs, usually it’s necessary to lock the entire digital system to that source, potentially degrading clock quality and often disrupting work flow.

When AUTO SRC is engaged, it’s possible to set either SOURCE path to a non-synchronous input without modifying the

Rosetta 200’s sample rate or clock source. For example, if the Rosetta 200 is the clock master of a digital system running at

96kHz, it’s possible to input signals from a 48kHz synth without clocking to that input or changing sample rate.

14) CALIBRATION – Press and hold the PROCESS button to engage CAL mode. The following buttons are used to change parameters in CAL mode:

Once in CAL mode, press PROCESS to set the channel(s) to calibrate, as indicated by the blinking

“Ouch” LED. It’s possible to calibrate each channel individually or both A/D or D/A channels simultaneously.

Press + (CLEAR) to raise the calibration level of the selected channel(s), press – (SOURCE to Digital

Outputs) to lower the calibration level.

In calibration mode, the LED meters display a “zoomed-in” range of digital levels between –20 and –10 dBFs, as shown in Figure 7 (pg 10); each column of LEDs now corresponds to a 1 dB change in level.

To aid in precise calibration, a single LED lights ONLY when the corresponding channel’s actual level is within +/- .1dB of the specified level, otherwise adjacent LEDs light to show that the actual level is between two specified levels. For example, if a tone connected to the analog inputs results in a digital level of -16.4 dBFs, both the “-16” and “-17” LEDs will light. When the actual level is within plus or minus

.1 dB of for example, -12 dBFs, ONLY the “-12” LED will light. Please note that when the Rosetta 200 is reset, it is calibrated to the default level of +4 dBu = -16 dBFs (+/- 0.2 dB).

APOGEE ELECTRONICS

Follow these steps to calibrate the Rosetta 200:

1 Before entering CAL mode, set both SOURCE (to Digital Outputs) and SOURCE (to Analog Outputs) to Analog.

2 Connect a 1 kHz tone at the desired analog reference level (usually +4 dBu) to both Analog inputs, and connect an analog meter (voltmeter or analog VU meter) to the Analog outputs.

3 Engage CAL mode by pressing and holding PROCESS.

4 Select the A/D channel(s) to calibrate, and press the + (CLEAR) or – (SOURCE to Digital Outputs) buttons until the desired digital reference level is displayed on the corresponding LED bargraph. When only one LED (per channel) is lit, the A/D is calibrated to within +- .1 db of the specified level.

5 Select the D/A channel(s) to calibrate, and press the + (CLEAR) or – (SOURCE to Digital Inputs)

15) APTOMIZER – A new Apogee technology developed for the Rosetta 200, APTOMIZER sets A/D and D/A calibration levels by detecting peak level information at the A/D converter and adjusting both analog inputs and outputs for the optimal setting. Think of APTOMIZER as an alert assistant who constantly re-calibrates the unit based on the input received (even if “alert assistant” is an oxymoron).

ON-OFF – turns APTOMIZER On or Off. Note that when APTOMIZER is turned Off, calibration levels return to the last manually adjusted values.

TRIM – Once the Rosetta 200 has determined an optimal calibration level in LEARN mode, it’s possible to trim this level using the – (SOURCE) and + (CLEAR) buttons. Each button push modifies calibration levels .1 dB.

LEARN – Press and hold the APTOMIZER button to engage LEARN mode. While in LEARN mode, the A/D calibration level is dynamically adjusted so that the highest peak detected at the analog inputs results in a digital level of -.5 dBFs. To preserve unity gain through the unit (i.e. what goes in is what comes out), the D/A calibration level is adjusted simultaneously.

APTOMIZER and Soft Limit – When LEARN mode is engaged, the A/D calibration level drops to its lowest gain value in order to comfortably accept input peaks up to +24 dBu. To avoid misdetection of peaks, Soft Limit is disengaged when LEARN mode is engaged. If using Soft Limit, it’s suggested to check calibration levels once LEARN mode is disengaged, and modify if necessary with the TRIM buttons (– (SOURCE) and + (CLEAR)).

When engaging LEARN mode, please note that previously detected calibration values set by

APTOMIZER are lost.

16) METERS – These bargraphs display the digital level of both SOURCE selections. When the Rosetta 200 is configured as an A/D – D/A (i.e SOURCE (to Digital Outputs) is set to Analog and SOURCE (to Analog

Outputs) is set to a digital source), the ANALOG bargraph displays the analog input after A/D conversion while the DIGITAL bargraph displays the digital input before D/A conversion.

17) SOURCE (to Analog Outputs) – This parameter selects the input source that is routed to the Analog outputs. When a digital input is selected, the Rosetta 200’s D/A converters are employed to convert the selected input to digital.

18) SRC (Sample Rate Conversion) – When a digital source has been selected, press and hold SOURCE (to

Analog Outputs) to engage SRC.

• USB Midi interface, compatible with OS used. Please note that Midi interfaces with proprietary latency-reducing modes do not properly transmit System Exclusive data such as this firmware update. Ensure that such modes are turned off before attempting to update firmware. USB Midi Interfaces such as the Edirol PC-300, where proprietary modes may not be turned off, are not compatible with this firmware update method.

1) To determine the version of firmware installed in the ROSETTA 200, press the SOURCE

(to Digital Outputs) button while powering on the unit.

2) Install both the ApogeeUpdater and the new firmware file onto a computer equipped with a USB Midi Interface. It’s assumed that all drivers necessary for the proper test and operation of the Midi

Interface have been installed.

3) Connect the ROSETTA 200’s Midi Update Connector to an

MIDI updater

output of the Midi Interface.

4) On the ROSETTA 200, press the SOURCE (to Analog Outputs) button while powering up the Apogee device; once the device has booted, release the SOURCE (to Analog Outputs) button.

When the signal level LEDs begin to “dance”, the unit is ready to receive data.

5) Open the ApogeeUpdater application, and click on OPEN FILE.

Figure 5

In the Navigation window which appears, navigate to the new firmware file, select it, and click on OPEN.

6) Click on DOWNLOAD TO UNIT.

7) The complete update process takes 8 minutes; after about 1 minute, data transfer should begin.

8) Once the download has reached 100%, wait for the unit to re-boot and the front panel to return to a normal operating state.

9) Before proceeding, reset the unit by pressing SAMPLE RATE while powering up the unit.
