Installing Symphony PCI Cards
1. As a safety precaution, unplug the computer’s AC cable.
2. To avoid electrostatic damage to the Symphony card, it is recommended that a grounded anti-static wrist
strap be used when installing the card.
3. Remove the Mac’s side cover (and air deector, if installing the card in a G5).
4. Remove the screw(s) securing the port access cover(s) of the required PCI slots and set them aside for later
use. Remove the port access cover(s).
5. After verifying jumper settings of the PCI card, align the card edge connector with the desired PCI slot and
press the card rmly into place until the gold pins of the edge connector are just visible. Be sure to insert the
end of the card without the connector into the appropriate card guide. If the card does not slide into place
with minimal effort, remove the card, check alignment and check for foreign objects. Don’t force the card into
place.
6. Re-install the access cover screw to secure the Symphony PCI card.
7. If multiple Symphony cards have been installed, connect the supplied ribbon cable between each PCI card as
shown below, making sure to align the key on the ribbon cable connector to the slot on the PCI card socket. If
only two Symphony cards are installed, use the connector on each end of the ribbon connector.
8. Re-install the Mac’s side panel (and air deector, if applicable)

Setting On-board Jumpers
Before installing Symphony PCI cards into your Mac, it’s necessary to assign a unique ID for each card
using the block of jumpers indicated in gure 1.
1. Remove the Symphony card from its anti-static bag, paying careful attention to not touch the on-board
components or the gold connector pins.
2. Set jumpers on each card according to the PCI slot used, as described in gure 2.

PC32 Connections
It is possible to connect Apogee AD16X, DA16X, Rosetta 800 and Rosetta 200 interfaces to Symphony
PCI cards in a wide array of congurations, for a total of 32 channels of simultaneous input and output per
PCI card. Please consult the Interface Connections Chart on pages 28-31 for a complete list of all the possible
combinations of Apogee interfaces that may be connected per PCI card.
The Interface Connections Chart depicts important aspects of each possible combination, including:
1) The order in which interfaces should be connected. As shown in the example below of an AD16X
and DA16X in Standard routing, the computer should be connected to the AD16X’s Main port, and the AD16X’s
Thru port connected to the DA16X’s Main port.
2) The connection between the interfaces’s I/O and the Symphony driver’s I/O. As shown in the
example below, the AD16X’s 16 analog inputs are connected to Symphony inputs 1-16, and Symphony outputs
1-16 are connected to the DA16X’s analog outputs. In this example, Symphony I/O 17-32 are unused, though
they still appear in your software I/O list.
Regardless of the Apogee hardware used, PC 32 cables should be connected as shown below, where the
Symphony PCI card is connected to the rst unit’s X-Symphony Main port, the rst unit’s Thru port is connected
to the second unit’s Main port, and so on until all interfaces are connected.
(Symphony PCI card installed in computer)
(X-Symphony Cards installed in Apogee
converters)
Word Clock Connection on Apogee Interfaces
Using a Master Clock (such as Apogee’s Big Ben)
1 Connect a word clock cable between outputs
of the master clock and each interface’s word
clock input, and terminate the input with a 75
ohm load.
2 Start your Mac, open the Maestro app, and
set Clock Source Select for the rst interface
to External. All remaining interfaces should
switch to their external word clock source.
3 If interfaces aren’t displayed in Maestro, select
Tools > Reset Symphony Clocking and click
on External Clock.
4When opening CoreAudio applications,
ensure that the master clock is running at
the same sample rate as the session you’re
opening.
Clocking to the rst interface
1 Install BNC “T connectors on the word clock
inputs of the second, third and fourth interfaces
(if present). Connect a word clock cable from
the rst interface’s word clock output to the
BNC “T” connector on the next interface, from
that interface to the next, until all the word
clock inputs have been chained together, as
shown in gure 2. Terminate the word clock
input of the last interface with a 75 ohm load.
2 Start your Mac, open the Maestro app, and set
Clock Source Select for the rst interface to
Internal. All remaining interfaces should switch
to their external word clock source.
3 When opening CoreAudio applications, the rst interface should switch to the same sample rate as
the session you’re opening, and all remaining interfaces should follow.

In the Symphony system the rst interface serves as the clock master to the entire system, and may be set to
Internal or External clock in Apogee’s Maestro application. All remaining interfaces must receive a word clock
signal synchronous with the rst interface’s clock source, whether Internal or External.
When a Symphony system is booted, the rst interface will switch to the clock source specied in Maestro
(Internal or External) while the remaining interfaces will switch automatically to their external word clock source.
The two most common ways to accomplish the necessary word clock connections are depicted below.

Installing the Symphony Core Audio Driver
Symphony Core Audio drivers must be installed on the computer to interface Symphony PCI hardware to Core
Audio compatible software. This driver may be found on the Apogee Software CD included with the Symphony
PCI card. More driver information may be found at Apogee’s website here:
http://support.apogeedigital.com/index.php/symphony-32/downloads
To install the driver:
1. Insert the CD into your Mac’s optical disc drive.
2. Double click on the Symphony Software Installer icon.
3. Follow the instructions provided by the installer program.
4. Re-start your Mac after installation is complete.
Important note: Sleep settings
Due to the processor intensive nature of computer-based digital audio systems, it’s required that OSX’s
“Sleep” functions be disabled.
1. Under the Apple menu, open the System Preferences window and click on the Energy Saver icon. In the
Energy Saver window, set both computer and display sleep sliders to “Never” and uncheck the hard disk
sleep box.
2. On a G5 : Under the “Options” tab, set Processor Performance to “Highest”.
• Open Logic Pro 8 and choose Logic Pro > Preferences > Audio.
• In the Preferences window, select the Devices tab, then the CoreAudio tab.
• Select Symphony 32 in the Device drop down menu.
• Set I/O Buffer Size to 64. If you encounter clicks and pops, choose a higher buffer setting.
• If not checked, check the Enabled box.
• Click on Apply Changes.
iTunes
1. From your Mac’s Menu bar Apple menu, open the System Preferences window, and click on the Sound
icon; in the Sound Preferences window, click on the Output tab and select Apogee Symphony.
2. Open iTunes, select an audio le, and initiate playback; signal is routed to outputs 1-2 of the rst con-
nected Apogee interface.
ConguringLogicPro8Word Clock Connections - Multiple Symphony PCI Cards
Regardless of the number of Symphony PCI cards to which hardware interfaces are connected, each
hardware interface must receive a synchronous word clock. For example in the system shown below, the rst two
interfaces are connected to one Symphony PCI card and the second two interfaces are connected to a second
PCI card, but all four interfaces are connected to the same clock source.

Connecting Symphony 32 and Symphony 64 with SBus
Using SBus, it’s possible to connect a Symphony 32-equipped Mac to a second Mac equipped with a
Symphony 64 system, following the steps described below. For a complete description of SBus and Symphony 64,
please consult the Symphony 64 User’s Guide.
Make PC-32 Connections
When interconnecting a Symphony 64 and 32 card via Sbus, connections must be made as shown in gure
1 at right. An Apogee hardware interface must be connected to port 1 of the Symphony 64 card, and the
Symphony 32 card must be connected to the Symphony 64’s port 2. The connection of multiple Symphony
32 cards via Sbus is not supported.
Set Symphony Source
On the Symphony 32 system, open Maestro and set Symphony Source to Symphony Card 1 (Chs 1-32).
On the Symphony 64 System, open Maestro and set Symphony Source to Symphony Card 1, Ports 1-2
(Chs 1-64). If the Maestro Control panel is greyed out, the setting may be made in the OS X utility Audio
MIDI Setup.
Set Software Sample Rate
Set the sample rate of both Macs to the same frequency. This may be done by opening a DAW session or
by opening Audio MIDI Setup, setting Properties For to Symphony 32, and setting Format to the desired
sample rate.
Verify in Maestro
Open Maestro on both Macs and verify that all hardware and SBus connections have been
detected correctly. To check for SBus connections, open the Maestro Control window and choose
Symphony:Symphony in the Interface drop down menu. The Mac to Mac icon shown in gure 2 should
appear.
Choose Symphony 32 Input and Output Labels
To facilitate the assignment of SBus I/O, it’s recommended to choose Maestro's default input and output
labels in your DAW software. To do this in Logic:
• Choose Options > Audio > I/O Labels
• Option-click the rst label in the Provided by Driver column
When Maestro’s default labels are used in your DAW, assigning one Mac’s outputs to a second Mac’s inputs
is as easy as setting output in one session to Sbus 1-2 and input in the second session to Sbus 1-2.
If your DAW software doesn’t accept Maestro’s default labels, the list below indicates how signals are routed
between Apogee hardware interfaces, Symphony 64 I/O and Symphony 32 I/O.
Apogee hardware interface inputs 1-32 > Symphony 64 inputs 1-32
Symphony 64 outputs 1-32 > Apogee hardware interface outputs 1-32
Symphony 64 inputs 33-64 (Sbus) > Symphony 32 outputs 1-32 (Sbus)
Symphony 64 outputs 33-64 (Sbus) > Symphony 32 inputs 1-32 (Sbus)

Maestro Control Window
Settings Pane
Apogee’s Maestro software provides control, routing and low latency mixing functionality for the
Symphony 32 system. The application consists of two windows, Maestro Control and Maestro Mixer.
Interface Drop Down Menu – The Interface drop down menu, found in the upper left corner of each Mae-
stro window, is used to select the Apogee interface whose settings are displayed in the Maestro window.
Details of the Interface drop down menu are shown below:
Identify Unit – This feature is disabled when interfaces connected via Symphony PCIe are selected.
Clock Source Select (This setting is duplicated in Audio MIDI Setup as Clock Source) - This drop down
menu is used to set the clock source of the rst hardware interface connected to the Master PCI card.
When set to Internal, the selected interface derives clock from an internal crystal; when set to External,
clock source selection varies with each Apogee interface, as described below.
Rosetta 800/200 – When set to External, the specic source (ADAT/SMUX, AES or WC input) must
be manually selected on the Rosetta’s front panel.
AD-16X – When set to External, the AD-16X accepts clock from its Word Clock input.
DA-16X – When set to External, the specic source (WC or Input) must be manually selected on the
DA-16X’s front panel.
If any other interface but the rst is selected in the Interface drop down menu, this setting will be greyed out.
Symphony Source (This setting is duplicated in Audio MIDI Setup as Source) - This drop down menu
selects PCIe cards to be enabled for use. Cards that have a PC-32 connection to hardware interfaces or
another Mac should be enabled, while unconnected cards should NOT be enabled. For space consider-
ations, the cards are numbered 1 to 3 in the Symphony Source drop down menu. Figure 1 indicates the
number assigned to each card.
If only Card 1 is in use, set Symphony Source to PCI Card 1 (CHANNELS 1-32)
If cards 1 and 2 are in use, set Symphony Source to PCI Cards 1-2 (CHANNELS 1-64)
If cards 1,2 and 3 are in use, set Symphony Source to PCI Cards 1-3, (CHANNELS 1-96)
If an unconnected card is enabled, no interfaces will appear in Maestro. Make sure that all enabled cards
have a PC-32 connection to an interface or another Symphony-equipped Mac.

VBus Selections - Apogee’s VBus creates virtual hardware buses to allow expanded routing of audio within
one application or between different audio applications. For example, it’s possible in Logic Pro to record
a submix of multiple audio tracks onto a new audio track as described below. It’s also possible to route
between two audio applications by selecting a VBus output in the source application and a VBus input in the
destination application.
To engage VBus, open Apogee’s Maestro application, select one of the Apogee interfaces connected to the
Symphony PCIe card, and open the Maestro Control window. In the VBUS Selections drop down menu,
select the number of virtual buses desired.
In order for VBus I/O to appear in your audio application’s I/O list as VBus In 1-2, 3-4, etc, it’s necessary to
specify the use of the Symphony driver’s names in the application’s I/O list. For example in Logic Pro, open
Audio>Audio Conguration>View>I/O Labels and option-click on all the I/O found under the Driver’s I/O
Label column.
As an example of how to use VBus, let’s record a submix of drums onto a new stereo audio track in
Logic.
First, open Maestro and select 8 Channels under the VBus Selections menu.
In Logic’s Track Mixer, set the outputs of the individual drum audio tracks to VBout 1/2. Create two audio
tracks (or one stereo track) and set their inputs to VBin 1 and VBin 2. Record-enable the new track and
commence recording. The new track will record the mix of the individual drum tracks.
Performance Tuning allows the adjustment of Symphony driver buffers to take advantage of the latest Intel
Macs’ increased CPU power.
Set Performance Tuning to High Performance when using Symphony 32 on an Intel Mac. This reduces
buffer sizes and ensures the lowest latency through the Symphony system.
Set Performance Tuning to Standard when using Symphony 32 on a G5 PPC Mac, or when software buffer
settings won’t resolve clicking and popping issues.
Performance Tuning is set in addition to the buffers typically found in digital audio applications. If audible
clicks and pops are encountered, rst raise the driver buffer size in the audio application. If problems persist
set Performance Tuning to Standard.

Input Pane
Maestro Mixer Window
Input, Output and Mixer Panes
Input and Output Panes
The Input and Output Routing panes consist of an intuitive routing grid on which connections between
hardware and software I/O are depicted and modied visually.
Connections are depicted by grey connection icons at the intersection of a hardware I/O column
and a software I/O row. To modify a connection, place the cursor over the grid at the intersection of the
desired hardware I/O column and software I/O row, and click on the highlighted grid position. The grey
connection icon will shift into the new position to indicate that the desired connection has been made.
As an example, the default state of the Input routing pane with a connected AD-16X is shown in gure
1. The AD-16X’s hardware inputs are displayed across the top of the grid, while software inputs are
displayed to the left of the grid. The grey connection icons, labelled L and R, are placed such that
hardware inputs Hardware In 1 and 2 are connected to software SymIn 1/2, hardware inputs
Hardware In 3 and 4 are connected to software SymIn 3/4, and so on.
Input Pane
The Input pane serves to connect hardware inputs to software inputs, as shown in gure 2. The following
controls are found in the Input pane:
Interface Menu – These controls, found at the top of the Input, Output and Mixer panes, are identical to
those found in the Maestro Control window described on page 36.
Matrix – The settings in these drop down menus dene how software inputs are formatted in the
routing grid:
Mono - software inputs are formatted as Mono signal paths.
Stereo - software inputs are formatted as Stereo signal paths.
Off - the signal path is deactivated.
Input – This column displays the software inputs available for routing. Software input names may be
modied by clicking on the triangle to the left of the Matrix to reveal a text entry box. For these names
to appear in your audio application’s I/O list, it’s necessary to specify this in the audio application.
For example, in Logic choose Options > Audio > I/O Labels and option-click on the rst entry in the
Provided by Driver column
Hardware In – This row displays the hardware inputs available for routing.
Mixer A In, Mixer B In – It’s possible to route the output of either the A or B mixer (found in the Mixer
pane) back into the software application. For example, when hardware synths are connected to the
hardware inputs of an Apogee interface, it’s possible to mix these synths using the Maestro mixer and
record the mix in your software application by assigning either the Mixer A In or Mixer B In to a
software path.
