DA-16X – User’s Guide
APOGEE ELECTRONICS
Introduction
The DA-16X, Apogee’s latest and most advanced digital to analog converter, takes the legendary quality of
Apogee a significant step forward. Features such as a redesigned power supply, standard 192kHz sampling rates,
the C777 clocking technology found in Big Ben, and optional Pro Tools HD and FireWire expansion cards, make
the DA-16X the most powerful and flexible D-to-A converter ever.
Advanced High-Definition Conversion
With up to 192k standard sample rates, the DA-16X combines Apogee’s legendary conversion quality with
the very latest in high-definition digital to provide unrivaled flexibility and quality.
C777 Clocking used by Big Ben
The DA 16-X uses Apogee’s C777 clocking technology. Famous for keeping Big Ben on time, the C777
utilizes an entirely digital process that Apogee has developed with the most advanced Direct Digital
Synthesis (DDS) technology and DSP-based digital filtering. With a stable, crystal based digital PLL
handling the clocking, the DA-16X is able to intelligently manipulate incoming signals and adapt to them
accordingly, resulting in unprecedented jitter attenuation and an astonishing and noticeable difference in
sound quality.
Advanced Option Routing
With version 2 firmware, both digital inputs and analog outputs may be routed in conjunction with an
installed X-Option card. Please see page 7 for details.
Universal Connectivity
With it’s wide array of standard and optional digital inputs, the DA-16X can be connected to virtually any
digital system. The DA-16X includes AES and ADAT Optical digital inputs as standard, while either the
X-HD or X-FireWire cards may be installed for connectivity to Pro Tools HD or any FireWire equipped
computer.
High Performance Output
The DA-16X uses Apogee’s newly developed electronically balanced line drivers, able to simulate true
transformer behavior. The circuitry is an ultra low output impedance, high current driver, capable of
running levels up to 26 dBu to the most complex or low impedance loads. Recording studios utilizing
vintage audio-equipment will find this particularly valuable. Ultimately, the output performance of the DA16X achieves perfect symmetry when used in balanced mode (even with an unsymmetrical load) and no
increased distortion when used unbalanced.

USING THIS MANUAL
In this manual, “parameters” are defined as the characteristics of operation, such as
CLOCK SOURCE or AES format, and are capitalized in this manner : CLOCK SOURCE.
“Values” are defined as the choices available for each parameter – for example, the parameter CLOCK SOURCE has
the values INTernal,WC and INPUT Values are italicized in this manner: S/PDIF.
“Settings” are defined as the entire set of parameters and values.
When physical controls such as buttons or switches are referred to in the text,
they are highlighted in this manner: DOWN.
INSTALLATION
Please ensure that the DA-16X is installed in a adequately ventilated location. It is recommended that a 1U
space be left between units if installed in a 19” electronics rack
CONNECTING POWER
The DA-16X 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 DA-16X, power up the unit while pressing the DOWN button. This provides a quick method to return
to factory default settings when exploring the unit’s functionality and capabilities. When reset, the conversion
level is set so a –16 dBFs digital input results in a +4 dBu analog output.
QUICKSTART
Follow these simple steps to get started quickly:
1)
2)
3)
4)
5)
Connect an AC input, the desired digital inputs and analog outputs to the DA-16X’s rear panel.
Reset the DA-16X by powering up the unit while pressing the DOWN button.
Once the DA-16X has booted up, press the DOWN button repeatedly until the INPUT indication is lit (in
the leftmost column of the Clock window).
Press the NEXT button repeatedly until the AES LED is flashing (in the column of LEDs above INPUT).
Press the UP or DOWN buttons until the desired input is selected.
The sample rate of the input should be indicated in the Clock window, the Narrow Lock indicator should
light, and audio should be present at the DA-16X’s outputs. If an X-Option card is installed, the DA-16X

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 DA-16X is installed in a rack with a Master power switch, the unit may be
configured to power on when the Master switch is turned on. Please see the section of this manual entitled
“Internal Adjustments” for details.
Note that the POWER switch LED indicates that the DA-16X is receiving a proper AC input, and is in
Standby. The LED goes out when the DA-16X is powered on.
2)
Setup buttons and LED - These buttons are used to modify all settings on the DA-16X. In general, setting
modification is accomplished by :
a) enabling Setup mode by pressing any of the 4 buttons (the Setup LED will light and one parameter
value will flash);
b) using the PREV or NEXT buttons to scroll to the parameter to be modified;
c) using the UP or DOWN buttons to select the desired parameter value.
After Setup mode is enabled, pressing the PREV or NEXT button will cycle through the DA-16X’s seven
parameters - CLOCK SOURCE, SAMPLE RATE, WC ratio, OPTICAL format, AES format, INPUT and CAL
mode- and then return to the first parameter. Likewise, pressing the UP or DOWN buttons will cycle through
the values available for the selected parameter. Once a value is selected, it immediately becomes active,
regardless if the LED is flashing to indicate that Setup mode has been enabled.
If the CAL parameter has been selected, pressing and holding either the PREV or NEXT button will allow the
user to enter Channel CAL mode; it’s now possible to cycle through channels 1-16 (plus two oscillator settings) in order to make settings to individual channels. Please see page 5 for more details concerning CAL
modes. Figure 1 depicts the parameter cycles of the DA-16X.

Parameters 3-7 are displayed in the Clock Window, as indicated at the top of this page.
3)
CLOCK SOURCE – This parameter determines the clock source of the DA-16X, and may be set to INTernal crystal,
WC input, or to the digital INPUT (as selected by the INPUT parameter).To use Optical input as a clock or input
source, the ADAT 1-8 input must be connected first in precedence. When AES input is selected as a clock or input
source, all inputs are scanned until a valid input is detected; this input is utilized as the clock source.
4)
SAMPLE RATE - When the CLOCK SOURCE is set to INTernal , the Sample Rate display indicates the frequency
of the internally generated clock, and may be set to all standard sample rates between 44.1 and 192 kHz. When the
CLOCK SOURCE is set to either WC or
INPUT, the display indicates the sample

input frequency. Likewise, the word clock
output frequency may be determined given a specific WC Ratio setting and DA-16X sample rate. This parameter
should be used to adjust the DA-16X word clock I/O to accommodate the requirements of specific digital systems.
For example, to configure the DA-16X to lock to a 48kHz word clock input and run at a sample rate of 192kHz, set
WC Ratio to WC fs/4.
6)
Lock indication – These LEDs indicate the Lock status of the DA-16X’s C777 clock. Two levels of lock precision
are displayed, Wide and Narrow. When the Narrow LED and Lock “exclamation point” are lit, the DA-16X has locked
to the selected CLOCK SOURCE in such a way to ensure the highest quality D-to-A conversion. If the Wide LED
or only the upper section of the Lock exclamation point lights, the stability of the clock source is questionable, and
should be verified.
Thanks to SureLock, Apogee’s intelligent clock continuity algorithm, the DA-16X will output a stable clock signal
even if the selected CLOCK SOURCE is interrupted. When SureLock is engaged, the arrow section of the Lock
exclamation point flashes to indicate a loss of the clock source, while the Narrow LED and blue point light solidly to
indicate a stable clock output.
7)
CAL mode indicator – This LED indicates that either Global or Channel CALibration mode is enabled, and that the
digital to analog conversion level may be calibrated. Global CAL allows the calibration of all 16 channels simultaneously, while Channel CAL allows calibration of individual channels. Global CAL mode is enabled by scrolling through
the 7 front panel parameters until the CAL LED flashes; “global Cal” will scroll across the Sample Rate display. Once
enabled, all 16 analog output levels may be adjusted by one of three operations:
• Press and Hold UP to raise the analog output level and DOWN to lower the level;
• Press and release UP or DOWN to modify the analog outputs +-.01 dB;
• Quickly tap UP or DOWN twice (think of a double mouse click) to modify the analog outputs +- 1.0 dB.
This double press function may be used to quickly jump from a “house” reference level to another
reference level in precise 1 dB steps.

When modifying calibration levels, the Sample Rate display depicts the “wheels of gain”, which rotate clockwise
to indicate increasing level and counterclockwise to indicate decreasing level, something like a volume knob.
Channel CAL mode is enabled by scrolling through the 7 front panel parameters until the CAL LED flashes,
then pressing and holding either the PREV or NEXT buttons until “ch 1” scrolls across the Sample Rate display.
Keeping in mind that Setup mode is always enabled while in Channel CAL mode, channel 1’s analog output may
be modified by the same operations described on the previous page. To adjust channels 2-16, press either the
PREV or NEXT button until the LED corresponding to the channel to be modified is lit.
Additionally, there are two extra parameters in the Channel CAL cycle: Oscillator On-Off and Oscillator Level. To
engage the oscillator, press PREV or NEXT (while in Channel CAL mode) until “OSC – OFF” scrolls across the
Sample Rate display, then press the UP button to turn the oscillator on (if the oscillator is on, press DOWN to
turn it off). To set the Oscillator level, press PREV or NEXT, until “OSC – 16dBFs” scrolls across the Sample Rate
display, and press UP or DOWN to set the oscillator to a value between -20 dBFs and 0 dbFs.
Saving calibration
settings
To exit Channel CAL mode, press and hold either PREV or NEXT again. Keep in mind that values entered while
in either Global or Channel calibration mode won’t be saved in non-volatile memory until Channel CAL mode is
exited and the Setup mode LED goes out.
Individual channel level changes made in Channel Cal mode are preserved when modifying all channel levels in
Global Cal mode.
To calibrate the DA-16X, engage the internal oscillator at the desired digital reference level (between -20 and -12
dBFs) and calibrate the analog outputs until the desired analog reference level (most often +4 dBu) is attained.
This may be most easily accomplished by measuring the AC voltage between the plus and minus legs of each
analog output, and adjusting the calibration level until a voltage of 1.23 volts AC is attained. Any modern digital
voltmeter will provide a sufficiently accurate measurement.
8)
OPTICAL format – The format of the Optical inputs may be set to ADAT, S/MUX2 or S/MUX4 to accommodate the Optical format of connected devices. If the CLOCK SOURCE is either INTernal or WC, the
OPTICAL format is determined by the Clock Source’s sample rate, and cannot be modified. If the CLOCK
SOURCE is INPUT and INPUT is set to ADAT, the OPTICAL format is specified by the user.
9)
AES format - The format of the AES inputs may be set to SINGLE or DOUBLE wire, to accommodate the
AES format of connected devices. If the CLOCK SOURCE is either INTernal or WC and the sample rate is
44.1- 48kHz, only the SINGLE value is available; in all other cases both values may be selected.
10) INPUT – The DA-16X’s digital input may be sourced from either the ADAT, AES or OPTION card inputs. The
OPTION value is not accessible when no card is installed. To use Optical input as a clock or input source,
the ADAT 1-8 input must be connected first in precedence. When the DA-16X is set to Advanced Option
routing configuration, the OPTION LED remains lit and INPUT may be toggled between ADAT and AES only.
Please see page 8 for details.
11) Level Meters – Much more than mere signal presence indicators, these LEDs display digital Input level from
–36 to 0 dBFs according to their brightness.

MIDI FIRMWARE UPDATE CONNECTOR
To allow the greatest flexibility in the field, Apogee now employs a firmware update method using
stardard Midi protocol. You’ll need the following items to update the firmware of your Apogee
device:
•
•
•
•
ApogeeUpdater program, available from Apogee’s website
New firmware file, also available from our website
Macintosh OSX 10.2 or higher or Windows XP computer
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 DA 16X, press the PREV 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
MIDI updater
necessary for the proper test and operation of the
Midi Interface have been installed.
3) Connect the DA-16X’s Midi Update Connector to an
output of the Midi Interface.
4) On the DA-16X, simultaneously press the PREV
and NEXT buttons while powering up the Apogee
device; once the device has booted, release the
PREV and NEXT buttons. 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. 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 and the percentage completed displayed on the ApogeeUpdater panel should
correspond to the percentage displayed on the DA-16X front panel.
8) Once the download has reached 100%, the unit will re-boot and the front panel will return to
a normal operating state.
9) Before proceeding, reset the unit by pressing DOWN while powering up the unit.
