A Letter from Bill Putnam Jr.
Thank you for deciding to make an Apollo High-Resolution Interface part of your music making experience.
We know that any new piece of gear requires an investment of time and money — and our goal is to make
your investment pay off. The fact that we get to play a part in your creative process is what makes our efforts
meaningful, and we thank you for this.
In many ways, the Apollo family of audio interface products represent the best examples of what Universal
Audio has stood for over its long history; from UA’s original founding in the 1950s by my father, through our
current vision of delivering the best of both analog and digital audio technologies.
Starting with its high-quality analog I/O, Apollo’s superior sonic performance serves as its foundation. This is
just the beginning however, as Apollo products are the only audio interfaces that allow you to run UAD plugins in real time. Want to monitor yourself through a Neve® console channel strip while tracking bass through
a classic Fairchild or LA-2A compressor? Or how about tracking vocals through a Studer® tape machine
with some added Lexicon® reverb?* With our growing library of more than 90 UAD plug-ins, the choices are
limitless.
At UA, we are dedicated to the idea that this powerful technology should ultimately serve the creative
process — not be a barrier. These are the very ideals my father embodied as he invented audio equipment to
solve problems in the studio. So as you begin to incorporate Apollo into your creative process, we hope that
the excitement and pride that we’ve built into it comes through. We believe Apollo will earn its way into your
creative workflow by providing stunning fidelity, great ease-of-use, and rock-solid reliability for years to come.
As always, please feel free to reach out to us via our website www.uaudio.com, and via our social media
channels. We look forward to hearing from you, and thank you once again for choosing Universal Audio.
Sincerely,
Bill Putnam Jr.

Introduction
What is Apollo 16?
Apollo 16 is a high-resolution audio interface with Realtime UAD Processing onboard that gives recording engineers a no-compromise monitoring, tracking, and mixing solution. The combination of Apollo 16’s high quality
converters, cue mixing, and digital signal processing help you achieve the goal of making music without the
common latency and potential processor shortcomings of an all-native system. Apollo 16 leverages Universal
Audio’s expertise in DSP acceleration, UAD Powered Plug-Ins, and analog hardware design by integrating the
latest cutting edge technologies in high-performance A/D-D/A conversion, DSP signal reconstruction, and host
connectivity. Apollo 16 acts as both an audio interface with integrated DSP effects for tracking and monitoring
as well as a fully integrated UAD-2 DSP accelerator for mixing and mastering.
Apollo 16 has four SHARC™ DSPs for running UAD Powered Plug-Ins during tracking or mixing. You have an
amazing sounding interface that can achieve the professional sound quality of any era in recording history by
using UAD Powered Plug-Ins.
Apollo 16 uses FireWire or Thunderbolt for computer connectivity. FireWire 800 doubles the performance of
FireWire 400 and ensures the ability to use all of Apollo 16’s I/O as well as its DSP processing. Thunderbolt is a
high-speed data transmission protocol that provides faster throughput than FireWire. The Thunderbolt Option
Card (sold separately) can be easily installed in Apollo 16’s expansion bay allowing Apollo 16 to connect with
Thunderbolt-equipped computers.
To fully realize the low latency potential of Apollo 16, the Console application is included, providing a familiar
analog mixing console interface where you can load your favorite combination of realtime UAD plug-ins. Configuring up to four unique cue mixes is quick and intuitive and you can also set up reverbs and delays (or any
other UAD effects) on two auxiliary buses for comfortable tracking of live microphones and instruments.
Achieving deep integration of Apollo 16’s features with your favorite audio workstation software is simple
thanks to the Console Recall plug-in that is compatible with VST, Audio Units, RTAS, and AAX 64 host software.
Simply place the Console Recall plug-in into any session and you have instant control over Apollo 16’s monitoring options. A single “Sync” button on the plug-in will automatically recall the Console configuration within the
DAW session without having to manage separate Console preset files, so you can be sure that the Console mix
you are working with today will be accurately recalled tomorrow.
Done tracking? Use Apollo 16 just like any other UAD-2 device for mixing in the DAW. The full UAD Powered
Plug-Ins library works with Apollo 16, offering the best analog emulation plug-ins available from the best
companies in pro audio such as Neve, SSL, Pultec, Teletronix, Studer, Lexicon, DBX, MXR, Harrison, Empirical
Labs, Manley, Ampex, and many more.* A single button in the Console lets you decide to “print” or “monitor”
Realtime UAD Processing – so if you want the sound of your favorite console and tape machine committed into
your DAW, you can print those effects on the way in.
Quite simply, Apollo 16 delivers the sound, feel, and flow of analog recording with all the conveniences of modern digital equipment.

Introduction
About Realtime UAD Processing
Apollo 16 has the ability to run UAD Powered Plug-Ins in realtime. Apollo 16’s groundbreaking DSP + FPGA
technology enable UAD Powered Plug-Ins to run with latencies in the sub-2ms range, and multiple UAD plugins can be “stacked” in series without incurring additional latency. Realtime UAD Processing facilitates the
ultimate sonic experience while monitoring and/or tracking.
Note: Apollo 16, like other UAD-2 devices, can only load UAD Powered Plug-Ins which are specifically
designed to run on UAD-2 DSP accelerators. “Native” plug-ins cannot run on the UAD-2 DSP.
Console
Realtime UAD Processing is a special function that is available only within the Console application. All of
Apollo 16’s analog and AES/EBU inputs can perform Realtime UAD processing simultaneously, and Console
inputs with (or without) Realtime UAD Processing can be routed into the DAW for recording.
For complete details about Console and Realtime UAD Processing, refer to the Apollo Software Manual (see
“About Apollo 16 Documentation” on page 8).
UAD plug-ins in the DAW
UAD Powered Plug-Ins can also be used within the digital audio workstation without the use of Console. UAD
Powered Plug-Ins loaded within the DAW operate like other (non-UAD) plug-ins, except the processing occurs
on the Apollo 16 DSP instead of the host computer’s processor. In this scenario, UAD plug-ins are subject to the
latencies incurred by I/O buffering.
For complete details about using UAD Powered Plug-Ins in the DAW, refer to the UAD System Manual (see
“About Apollo 16 Documentation” on page 8).
Combining with other UAD-2 devices
Apollo 16 can be used simultaneously with UAD-2 devices in the same host computer system. Apollo 16 simply
adds to the DSP availability when used with other UAD-2 devices, increasing the DSP processing power so more
UAD Powered Plug-Ins can be used. Up to six UAD-2 devices can be combined in the same system.

OFF
(1) Meter
The METER button determines which signals, either input or output, are displayed by the Channel Meters (4).
Push the switch to toggle the meter display state between Input and Output. The current meter state is displayed by the METER indicators (2).
(2) Status Indicators
These indicators display the status of the host computer connection, clock, and signal meters, as described
below.
Host
The HOST indicator displays the status of the connection to the host computer system. The indicator is illuminated when Apollo 16 is connected to, and properly communicating with, the host computer system via FireWire
or Thunderbolt. The indicator is off when the host computer is not detected.
The Apollo 16 software must be properly installed and configured on the host computer to enable communication, and the HOST indicator must be illuminated to use Apollo 16 with all computer operations. The only time
the HOST link is not required is when Apollo 16 is used without a computer (see “” on page 7).
Clock
The CLOCK indicator displays the status of the Apollo 16 clock. When Apollo 16 is using its internal clock as the
master clock source, the INT indicator is illuminated.
When Apollo 16 is set to use an external clock as the master clock source and a valid clock signal is detected at
the specified port, the EXT indicator is illuminated and white.
If the EXT indicator is illuminated and red, Apollo 16 is configured to use an external clock but it cannot lock
to the specified source, and the internal clock remains active instead. In this situation, if/when the specified
external clock becomes available, Apollo 16 switches back to the external clock, and the EXT indicator is illuminated and white.
Note: Apollo 16 can be configured to use its internal clock, or an external clock from the Word Clock or
AES/EBU inputs. The clock setting is configured in the Interface panel of the Console Settings window;
see the Apollo Software Manual for details.

Front Panel
Meter
The METER indicator reflects the state of the Channel Meters (4). The I/O state of the Channel Meters is
switched with the METER button (1).
When IN is illuminated, the Channel Meters display levels at the analog inputs. When OUT is illuminated, the
Channel Meters display levels at the analog outputs.
(3) Sample Rate Indicators
The Apollo 16 sample rate is indicated in this area. The active sample rate is illuminated.
(4) Channel Meters
The sixteen 10-segment LED meters display the signal peak levels for analog channels 1 – 16. The Channel
Meters can display either the input or output levels, as determined by the METER button (1).
Signal levels are displayed at the input to the A/D converters (IN mode) or the output of the D/A converters (OUT
mode). The dB values of the meter LEDs are indicated between the meters for channels 4 & 5 and 12 & 13.
“0” indicates a level of 0 dBFS. When digital clipping occurs, the red “C” LED illuminates. Avoid digital clipping at the channel’s A/D converter by reducing the channel’s level at its source.
(5) Power Indicator (UA Logo)
The Universal Audio logo illuminates when the external power supply is properly connected to an AC outlet and
the power input on the rear of the unit, and the POWER switch (9) is in the up position.
(6) Monitor Output Level Meters
These dual 10-segment LED meters display the signal peak output levels for the monitor outputs at the output
of the D/A converters. These meters are before the Monitor Level control (pre-fader) and reflect the D/A converter levels regardless of the current Monitor Level knob setting (7).
The dB values of the monitor meter LEDs are indicated between the left and right channel meters. “0” indicates
a level of 0 dBFS. When digital clipping occurs, the red “C” LED illuminates. Avoid clipping at the monitor D/A
converters by reducing the monitor bus output level and/or the channels feeding the monitor output bus.
(7) Monitor Level and Mute Knob
This “endless” rotary encoder serves two functions. Rotating the knob adjusts the monitor output level, and
pushing the knob mutes the monitor outputs, as described below.
Monitor Level
The control knob adjusts the signal level at monitor outputs on the rear panel. Although this is a digital control,
the monitor volume is attenuated in the analog domain, after D/A conversion (digitally-controlled analog
volume). This method provides the utmost monitoring fidelity, in contrast to digital volume controls that reduce
levels by truncating the word length (“dropping bits”). The available range is from -INF dBFS (no output)
to 0 dBFS.
Apollo 16 Hardware Manual

Front Panel
Monitor Mute
Pushing the Monitor knob toggles the mute state of the signals at monitor outputs on the rear panel. When the
monitor outputs are muted, the Monitor Level Indicator (8) is red. When the monitor outputs are not muted, the
Monitor Level Indicator is green.
(8) Monitor Level Indicator
The signal level at the rear panel monitor outputs is displayed with the illuminated indicator ring surrounding
the Monitor Level knob (7). The ring is green when the monitor outputs are active, and red when the monitor
outputs are muted. This level indicator is after the Monitor Level control (post fader).
Note: This feature indicates relative levels only and is not calibrated to any specific dB values.
(9) Power Switch
This switch applies power to Apollo 16. When the unit is powered on, the Universal Audio logo is illuminated.
The external power supply must be properly connected for this switch to function.
As with any sound system, to avoid audio spikes in your speakers, the following steps are recommended:
• Apply power to the speakers last, after all other devices (including Apollo 16) are powered on.
• Turn off the speakers first, before all other devices (including Apollo 16) are powered off.

(1) Monitor Outputs 1 & 2
These balanced XLR jacks are line-level analog outputs typically used for connection to a stereo loudspeaker
monitoring system. The signal levels at these outputs are controlled with the Monitor Level knob (7).
The Monitor Outputs can be configured to use reference levels of +4 dBu or -10 dBV. This function is configured
in the Outputs panel of the Console Settings window in the Console application.
The Monitor Outputs are completely independent from the 16 analog line outputs. By default, the “1–2” or
“Main” outputs from a DAW are routed to these outputs. Stereo panning of input signals routed to these outputs is defined within the Console and/or DAW applications.
NOTE: The AES/ABU outputs can be configured to mirror the Monitor Outputs. See “(8) AES/EBU Ports”
on page 15 for details.
(2) Line Outputs 1 – 16
The 16 analog outputs are accessed via dual female DB25 connectors. Each DB25 jack carries eight balanced
line-level channel outputs using standardized Tascam wiring.
The Line Outputs can be configured in adjacent pairs to use -10 dBV or +4 dBu reference levels. This function
is configured in the Outputs panel of the Console Settings window in the Console application.
(3) Line Inputs 1 – 16
The 16 analog inputs are accessed via dual female DB25 connectors. Each DB25 jack carries eight balanced
line-level channel inputs using standardized Tascam pinouts.
The Line Inputs can be configured to use -10 dBV or +4 dBu reference levels. This function is configured within
the input channel strips in the Console application.
Note: See “DB25 Wiring” on page 32 for DB25 connector pinout diagrams.

(4) Power Input
The included 80-watt external power supply plugs into this 4-pin locking XLR jack. Apollo 16 requires 12 volts
DC power and draws approximately 40 watts. During typical operation when a bus-powered Thunderbolt peripheral is attached to the Thunderbolt Option Card, the system can draw up to 55 watts.
To eliminate risk of circuit damage, connect only the factory-supplied power supply. Use the Power switch on
the front panel to power the unit on and off.
Important: Do not disconnect the power supply while Apollo 16 is in use, and confirm the Power
switch is in the “off” position before connecting or disconnecting the power supply.

(5) Word Clock Out
This BNC connector transmits a standard (1x) word clock when Apollo 16 is set to use its internal clock. The
clock rate sent by this port matches the current system sample rate, as specified in the Interface panel of the
Console Settings window within the Console application.
When Apollo 16 is set to use external word clock as its clock, Apollo 16 is a word clock slave. If the incoming
external word clock is within ±0.5% of a supported sample rate (44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz,
192 kHz), Word Clock Out will mirror Word Clock In with a slight phase delay (about 40ns).
(6) Word Clock In
Apollo 16’s internal clock can be synchronized (slaved) to an external master word clock. This is accomplished
by setting Apollo 16’s clock source to Word Clock in the Interface panel of the Console Settings window within
the Console application, connecting the external word clock’s BNC connector to Apollo 16’s word clock input,
and setting the external device to transmit word clock. If Apollo 16 is the last device in the clock chain, the
Termination switch (7) should be engaged.
Note: Apollo 16 can be synchronized to an external “1x” clock signal only. Superclock, overclocking,
and subclocking are not supported.

(7) 75 Ohm Word Clock Termination Switch
This pushbutton switch provides internal 75-ohm word clock input signal termination when required. Word
clock termination is active when the switch is engaged (depressed).
Apollo 16’s termination switch should only be engaged when Apollo 16 is set to sync to external word clock and
it is the last device at the receiving end of a word clock cable. For example, if Apollo 16 is the last “slave” unit
at the end of a clock chain (when Apollo 16’s word clock out port is not used), termination should be active.
Note: For more information, see “Digital Clocking Basics” on page 26.
(8) AES/EBU Ports
The AES/EBU ports provide two channels of digital I/O with resolutions up to 192 kHz via XLR connectors. For
optimum results, use only high-quality 110-ohm XLR cables specifically designed for AES/EBU digital audio.
SR Convert
Sample rate conversion can be enabled on the AES/EBU input. This function is set in the AES/EBU input channel strips in the Console application. When sample rate conversion is enabled and the sample rate of the
incoming AES/EBU signal does not match the sample rate specified in the Console application, the AES/EBU
signal is converted to match Apollo 16’s sample rate.
Note: When Apollo 16 is set to use AES/EBU as the master clock source, sample rate conversion is
inactive.
Mirror Monitor Outputs
The AES/EBU output can be configured to mirror the Monitor outputs, for routing the stereo Monitor signal to the
stereo AES/EBU input of other devices. This function is configured in the Interface panel of the Console Settings
window in the Console application.

Host I/O
Important: Connect only one Apollo 16 FireWire or Thunderbolt port to the host computer.
(9) Expansion Bay
The expansion bay is where the Universal Audio Thunderbolt Option Card is installed, providing access to all of
Apollo 16’s features and functionality via Thunderbolt-equipped computers.
Refer to the Installation & Setup Guide included in the Thunderbolt Option Card package and our website for
complete details about installation, configuration, and use of Thunderbolt with Apollo 16.
(10) FireWire 800 Ports
Apollo 16 uses FireWire to communicate with the host computer system when the Thunderbolt Option Card is
not in use. When Apollo 16 is properly connected and configured, the HOST indicator (#2 on front panel) is illuminated.
Apollo 16 has two FireWire 800 ports. Only one port is used to connect to the host computer; the second port
can be used for daisy-chaining multiple FireWire devices such as external FireWire hard drives. For more
FireWire information and recommended interconnections, see ““FireWire Basics” on page 22.
Note: Apollo 16 cannot be bus powered and it does not supply bus power from its FireWire ports to
other devices.
(11) MADI Optical Ports
The MADI I/O ports use the MADI (Multichannel Audio Digital Interface) optical protocol for Apollo 16 interconnections. The MADI ports relay the Monitor, Cue, and Auxiliary buses between two Apollo 16 units when multiunit cascading via FireWire for increased simultaneous I/O.
Note: The MADI ports support Apollo 16 interconnections when multi-unit cascading via FireWire only.
Connections to other MADI devices is not supported.

When more I/O and/or DSP is needed, two Apollo 16’s can be cascaded together via FireWire in a multiple-unit
configuration. For examples, see “Interconnections” beginning on page 18. For complete details about multiunit cascading, refer to the Apollo Software Manual.
Note: Up to for Apollo interfaces can be cascaded together with Apollo Expanded v8 software if all
Apollo units are connected via Thunderbolt. See www.uaudio.com/support/thunderbolt for complete
details.

Installation Notes
1. Apollo 16 may get hot during normal operation if it doesn’t receive adequate airflow circulation around
its chassis vents. For optimum results when mounting Apollo 16 in a rack, we recommend leaving at
least one empty rack space above the unit to allow adequate airflow for cooling.
2. As with any sound system, to avoid audio spikes in your speakers, the following steps are recommended:
• Apply power to the speakers last, after all other devices (including Apollo 16) are powered on.
• Turn off the speakers first, before all other devices (including Apollo 16) are powered off.
Typical Setup
This diagram illustrates a basic Apollo 16 system. In this example, only analog devices are connected; digital
I/O is not used.
Key points for this example:
•
•
•
•
Either FireWire port can be used for the host computer connection
The Monitor outputs are connected to powered monitors (or an amp+speaker system)

Multi-Unit Cascading Setup – FireWire Host Connection
This diagram illustrates how two Apollo 16 units are connected together into an aggregated interface for 32
simultaneous analog inputs and 32 simultaneous analog outputs using FireWire 800 to connect to the host
computer.
Important: For complete details about system operation when multi-unit cascading, see the Apollo
Software Manual.
Cables Required:
• One FireWire 800 cable for connecting to the host computer
• One FireWire 800 Cable for connecting between the two interfaces
• One MADI optical cable for connecting between the two interfaces
(single or dual MADI cables can be used)
Key points for this example:
• One unit is designated as the “Monitor” (the master unit – where monitor connections are made)
• One unit is the “Expander” (the slave unit – with higher numbered I/O)
• The Monitor unit is connected to the host computer via FireWire 800
(either Apollo 16 FireWire port can be used for this connection)
• The Expander unit is not connected to the host computer
• One FireWire 800 cable must be connected between the Expander and Monitor units
(either Apollo 16 FireWire port can be used for this connection)
• One MADI optical cable must be connected from the MADI OUT of the Expander unit to the MADI IN of
the Monitor unit
• Monitor and cue outputs are connected to the Monitor unit only

Apollo Expanded: Multi-Unit Wiring - Thunderbolt Host Connection
The diagram below illustrates how to interconnect multiple Apollo units and the host computer via Thunderbolt
when using Apollo Expanded software (UAD v8 or higher) for Thunderbolt systems.
Important: For complete details about system operation when multi-unit cascading, see the Apollo
Software Manual.
Cables Required
• One Thunderbolt cable for each Apollo unit
Note: All Apollo rack units require Thunderbolt connections.
Apollo Expanded Wiring Notes
• A single Thunderbolt cable is required for all device interconnections. Connect one cable to the host
computer and one cable between Apollo units.
• Thunderbolt 1 or 2 ports may be mixed and used for any/all connections.
• The computer and all Apollo units must be connected to the same Thunderbolt bus.
• The Apollo device ordering and the Thunderbolt ports used (second port on Apollo vs. second port on
computer, placement in daisy chain, etc) is not important.
• In the wiring example diagram, the lower Apollo 8 is designated as the monitor (master) unit. Connect
speakers (including ALT speakers) to the monitor unit only.
• Do not connect more than one Thunderbolt cable between thev same two devices (the Thunderbolt protocol is bidirectional).
• Do not interconnect any Word Clock, FireWire, ADAT, or MADI ports between any Apollo units.
Note: The FireWire ports are disabled with Apollo Thunderbolt software.

FireWire Basics
FireWire (also known as “IEEE 1394” and “i.Link”) is a high-speed serial data interconnection protocol that is
used to transfer digital data between devices. FireWire is commonly used to interconnect computer systems to
hard drives, audio interfaces, and digital camcorders. A complete discussion of FireWire is beyond the scope of
this manual, but some of the main points and how they apply to Apollo 16 are covered below.
Important: On Windows systems, Apollo 16 requires a qualified PCIe-to-FireWire adapter card. For
details, see www.uaudio.com/support/apollo
FireWire vs. USB
FireWire is considered superior to USB for audio purposes because it does not rely on the host processor to
manage low-level data housekeeping (among other reasons). FireWire typically outperforms USB at the same
rated speeds.
FireWire Bus
FireWire devices are connected to a FireWire “bus” which is comprised of all devices in the serial data stream.
The FireWire specification supports up to 63 devices per FireWire bus.
Many FireWire devices and host computers have more than one FireWire connector, but these connectors almost
always attach to the same FireWire bus (most computers do not have more than one FireWire bus). It is possible
to add another FireWire bus to a computer, typically by adding a PCIe-to-FireWire or ExpressCard-to-FireWire
adapter card.
Bus Power
Some FireWire devices can be “bus powered” which means the device derives its operating electricity from the
FireWire bus itself without a power supply of its own. Apollo 16 cannot be bus powered and it does not supply
bus power from its FireWire ports to other devices.
Powering Down
Powering down or disconnecting Apollo 16 when UAD plug-ins are loaded could cause session data loss and/
or unpredictable behavior. Quit all UAD host applications (DAW, Console, UAD Meter & Control Panel) before
disconnecting Apollo.
FireWire 800 vs. FireWire 400
The most common FireWire devices are available in two speeds: FireWire 400 (IEEE 1394a), which supports
transfer speeds up to 400 megabits per second, and FireWire 800 (IEEE 1394b), which supports up to 800
megabits per second. It’s usually possible to determine the speed of the FireWire device by the type of FireWire
connector it uses. Apollo 16 is a FireWire 800 device.
Apollo 16 Hardware Manual
22
FireWire Basics
FireWire Connectors
FireWire 800 and FireWire 400 devices use different connectors, as illustrated below. This helps to differentiate
between the two device speeds (the connectors are not interchangeable).
FW 800 (9-pin)
FW 400 (6-pin)
FW 400 (4-pin)
FireWire 400 connectors
FireWire 400 devices typically have two types of connector: 4-pin and 6-pin. The small 4-pin FireWire 400
connector is common on digital camcorders and Windows notebook computers. The 6-pin connector is more
common with hard drives and audio devices.
FireWire 800 connector
FireWire 800 devices use a 9-pin connector. 9-pin to 6-pin FireWire adapter cables are available to connect
FireWire 800 devices to a FireWire 400 bus (with half the bandwidth).
Apollo 16 has two FireWire 800 ports to facilitate easy daisy chaining with other FireWire devices.
FireWire Repeaters and Chains
FireWire devices can be connected to each other serially in a “daisy chain,” connected to a central device such
as a computer with multiple FireWire ports or a peripheral FireWire repeater, or any combination of the two in a
“tree chain” topology.
Apollo 16 can function as a FireWire repeater, by using the unused port on the unit to connect other FireWire
devices. Note that Apollo 16 does not supply FireWire bus power to downstream devices.
The examples below show a few of the many interconnection possibilities using daisy chains and repeaters.

FireWire Basics
Digital Clocking Basics
Digital clocking can be a complicated issue, with a number of important aspects that are often not very well
understood.
First and foremost, a digital clock is used to maintain synchronization between different digital devices. There
are two primary purposes for clock synchronization:
• Digital Conversion. Analog-to-digital (A/D) conversion and digital-to-analog (D/A) conversion need extremely accurate clocking in order to correctly process the digital data. A low-quality clock can degrade
the signal in many ways, including loss of transparency, clarity, imaging and transient response, as
well as increased noise and distortion.
• Digital Transmission. All digital devices need accurate clocking in order to properly transfer digital
data between interconnected devices. A low-quality clock can cause data reception errors, which add
distortion and noise, and if the clock isn’t synchronized correctly, samples may be dropped or repeated,
resulting in audible clicks or dropouts.
Clock quality is defined two ways: First, the sample rate must match the signal. This is referred to as “sample
rate synchronization.” Second, the clock signal must be stable over both short-term and long-term clocking intervals. “Jitter“ refers to short-term clock accuracy, and “stability” or “drift” refers to long-term clock accuracy.
These terms are discussed in more detail below.
Sample rate synchronization is required for proper digital transmission, and is relatively easy to maintain.
Basically, there must be one and only one “clock master“ for all interconnected digital devices. This is done
by setting one device to “master” mode (where it synchronizes to its internal clock and transmits that clock
signal) and setting every other device to “slave“ mode (where it receives and synchronizes to external clock),
with the appropriate clock signal routed between the master and slave devices. Keep in mind that any device,
whether it’s the clock master or a slave, can send or receive data once everything is synchronized correctly.
When doing digital conversion, it’s best to have the converter serve as the clock master. For example, if you’re
recording, clock everything off the A/D converter. Likewise, if you’re mixing, clock everything off the D/A converter. If you’re running multiple converters, use the device with the best quality clock as master.
For all-digital transfers, e.g., a digital transfer from one DAW or storage device to another, clock synchronization is maintained by simply setting up the proper master-slave relationship between devices. Digital transfers
can be affected by clock jitter, but not in the same way clock jitter affects analog conversion. This is a widely
misunderstood concept we’ll discuss in detail below.
Clock jitter is short-term variations in the timing of edges of a clock signal, as opposed to clock drift, which
is long-term variation in the clock rate. A clock could be very stable over the long term, but still have jitter,
and vice versa. Timing variations are caused by noise and/or interference. If the noise/interference is a highfrequency signal, the result is jitter, and if the noise/interference is a low-frequency signal, the result is drift.
As an analogy, a car with an out of balance wheel may drive straight, but you’ll get lots of vibration (jitter);
conversely, a car with a loose steering wheel might have a smooth ride, but it will drift all over the road.
Clock drift affects long-term synchronization, like sound to picture, and can introduce slight pitch variations in
the audio. Usually however, the drift is so slow that these pitch variations are only tiny fractions of a cent, and
thus unnoticeable.
Apollo 16 Hardware Manual
26
Digital Clocking Basics
Clock jitter affects digital transmission and digital conversion differently, as follows:
• Clock jitter in digital transmission can be caused by a bad source clock, inferior cabling or improper
cable termination, and/or signal-induced noise (called “pattern-jitter” or “symbol-jitter”). Digital
signal formats like AES/EBU, S/PDIF, and ADAT all embed a clock in the digital signal so the receiving device can synchronize to the transmitted data bits correctly. The clock used for data recovery is
extracted from the signal using a clock synchronization circuit called a phase-locked-loop (PLL). This
data-recovery PLL must be designed to respond very quickly to attenuate high-frequency jitter and
avoid bit errors during reception. This clock from the data-recovery PLL cannot be used to generate the
clocks used for digital conversion without further clock conditioning! This is a very common design
flaw in most low- and mid-range digital converters.
• Clock jitter in digital conversion is what most people refer to when they discuss jitter. It’s easily observed in a digital signal by looking at its spectrum in the frequency domain. A jittery signal will have
“side-lobes” around each frequency and/or spurious tones at random, inharmonic frequencies. Usually, the jitter will be worse with higher signal frequencies. You can test your converters by sampling a
high-quality 10 kHz sine wave, and viewing it in the frequency domain (available with any good wave
editing software package).
All modern over-sampling digital converters require a clock (called “m-clock”) that is many times (typically
several megahertz) higher than the sample clock. M-clock is easy to generate when the converter is the clock
master, but quite difficult to generate correctly when the converter needs to sync to an external clock.
External clock typically comes from a dedicated word clock input, or is extracted from an incoming digital AES/
EBU, S/PDIF, or ADAT signal. Word clock cannot be used by the converters until it is multiplied up to the m-clock
rate. This requires a PLL or other frequency multiplier circuit which will either be cheap and jittery, or expensive and clean, depending on who makes the converter. As we said earlier, the clock recovered from the digital
inputs is unsuitable for use as the converter’s m-clock, but because it’s conveniently at the same frequency,
many designers don’t bother cleaning up this signal.
Since the clock recovery, clock multiplier, and clock conditioning circuitry define the jitter for analog conversion, no external clock source can clean up the jitter introduced by these circuits, regardless of how perfect the
external source clock is. The best they can do is avoid making it any worse, but this is hardly worth the cost:
It’s much better (and less expensive) to use a good converter like Apollo than it is to try and fix a bad one with
an expensive master clock. The only reason to spend money on a high-quality master clock is to ensure that
multiple devices are synchronized correctly. This is essential for working with audio for film/video, or when
synchronizing multiple high-quality converters. A poor master clock can also affect imaging and clarity in a
multi-track environment.
Apollo 16 provides high-quality A/D and D/A conversion for recording and/or playback. With its pristine audio
path and high-quality clocking, it makes a great master or slave audio interface for every digital studio, and
thus provides a very cost effective way to improve overall sound quality.

Important Safety Information
Before using this unit, be sure to carefully read the applicable items of these operating instructions and the safety suggestions. Afterwards, keep them handy for future reference. Take special care to follow the warnings indicated on the
unit, as well as in the operating instructions.
1. Water and Moisture - D o not use the unit near any source of water or in excessively moist environments.
2. Object and Liquid Entry - C are should be taken so that objects do not fall, and liquids are not spilled, into the enclosure through openings.
3. Ventilation - W
hen installing the unit in a rack or any other location, be sure there is adequate ventilation. Improper
ventilation will cause overheating, and can damage the unit.
4. Heat - The unit should be situated away from heat sources, or other equipment that produces excessive heat.
5. Power Sources - The unit should be connected to a power supply only of the type described in the operating instructions, or as marked on the unit.
6. Power Cord Protection - A C power supply cords should be routed so that they are not likely to be walked on or pinched
by items placed upon or against them. Pay particular attention to cords at plugs, convenience receptacles, and the
point where they exit from the unit. Never take hold of the plug or cord if your hand is wet. Always grasp the plug
body when connecting or disconnecting it.
