1. INTRODUCTION.
1.1. General description.
AEQ PHOENIX STRATOS is a multiformat, multi-algorithm dual channel audiocodec designed
for stationary rack-mounted applications, like links between studios, STL or mobile equipment
connections. Each one of the two channels is stereo, so actually the unit houses two stereo
codecs with independent AES/EBU digital and analog inputs and outputs.
PHOENIX STRATOS is a rackmounted audiocodec offering the options of working over ISDN,
V35/X21 and IP networks. When used over the IP communications interface, it is fully
compatible with the EBU-TECH 3326 technical specification issued by the EBU N/ACIP working
group. This specification was developed to guarantee compatibility between devices made by
different manufacturers for professional quality audio contribution applications over IP networks.
PHOENIX STRATOS enables its users to work simultaneously over two channels with
professional quality in independent dual mono format or in stereo, or combination of both to
several different destinations.
PHOENIX STRATOS is designed to ensure interoperability with existing and future
communications equipment developed by AEQ and other manufacturers, thanks to the large
number of interfaces and of encoding algorithms it implements, and to the possibility of easily
bringing them up to date as the market evolves.
We recommend you reading this manual and “AEQ ControlPHOENIX” application user’s
manual carefully and completely before using the unit, although chapter 5 offers a
quickstart user’s guide.

It’s compatible with Phoenix MOBILE and STUDIO in ISDN communications.
The ISDN interface allows its users to communicate with other devices equipped with ISDN
interfaces, included in TLE02D, SWING, MPAC, EAGLE and COURSE ISDN boards.
V35 interface is compatible with EAGLE and Ranger devices.
1.6. Compatibility with other manufacturers’ codecs.
PHOENIX STRATOS is a stationary encoder over IP, fully compatible with the EBU-TECH 3326
technical specification formulated by the EBU N/ACIP working group. The specification was
developed to guarantee compatibility between different manufacturers in applications for
contributing professional quality audio over IP networks. Therefore, the PHOENIX STRATOS
can be connected with any codec made by another manufacturer with guaranteed connection
over IP, provided that the other unit was developed according to N/ACIP (see technical
specifications).
For ISDN communications compatibility is usual with almost all equipments, although it will
depend essentially on the coding algorithms implemented by the manufacturers of the other
equipment, since the signalling part is practically universal. This is why we recommend
consulting, before operating with other manufacturers’ equipment, the technical characteristics
of that equipment.

2. PHYSICAL DESCRIPTION OF THE UNIT.
To understand how the PHOENIX STRATOS unit is wired and installed, you will first need to
familiarize yourself with the connectors and other configurable elements that are present on the
front and rear panels of the device.
2.1. Description of the front panel and controls.
2.1.1. Multifunction display.
High-contrast 256x64-pixel OLED screen in black and yellow. Within the internal menu, the
screen gives a generic display of three differentiated areas:
-The upper area indicates the name of the menu where you will find the currently
displayed options.
-The central area is associated with the various functions in whatever menu is currently
being displayed; it is also the area where notifications and messages are shown.
-The lower screen area always shows options associated with the four lower keys that
function as contextual buttons.
2.1.2. Screen-associated keys / Contextual buttons.
Four multifunction buttons. Contextual operation depending on the menu options being
displayed on the last line in the multifunction screen at any moment.
2.1.3. Browsing encoder.
This enables cursor browsing in the various multifunction screen menus. Turning it makes the
selection on the cursor or highlighted on the screen of the options shown on the various lines of
the display, shifting from up to down and vice versa. Turning the encoder to the right raises the
cursor or highlighted element; turning it to the left lowers it.
Pressing the button allows you to validate the selection you currently have active on the cursor
or highlighted on the screen.
2.1.4. ESC button.
Performs the Escape function, enabling you to shift backward in the various multifunction
screen menus or cancel selections. Its operation produces the opposite effect of pressing the
browsing encoder; it returns you, in the multifunction screen, to the menu immediately previous
to the one currently being displayed.
RECOMMENDATION: by repeatedly pressing this key, a relatively untrained user will always
return to the initial system screen, regardless of the internal menu being displayed immediately
before pressing; no changes will be saved.

2.1.5. Alphanumeric keypad.
Standard 12-keys alphanumeric keypad that enables the user to perform many functions,
including the following:
-Enter a number when you wish to make a call through the ISDN interface
-Enter numbers and letters when you want to make a call through the IP interface, or
when you create or edit phone book entries.
To change between different letters of the alphabet associated with the same key, press the key
repeatedly until the desired letter appears, just as you would with a cell phone.
NOTE: The * key lets you switch between lower and upper case and only numbers. The 1 and #
keys allow you to create the special characters (among there are @ and “.”) and the 0 key
allows you to create the number “0” and the space character.
2.1.6. VU meters.
Two stereo monitoring VU meters. They can be configured in 3 different modes: as stereo input
signal & stereo output signal for each one of the two channels, or as two independent mono
signals with their corresponding input and output levels (both channels simultaneously).
The serigraphed lettering on the front panel identifies them, from left to right, as “CH1 RX“, “CH1
TX“, “CH2 RX“ and “CH2 TX“. If a stereo connection is made, and vu meters are configured this
way, “CH1 RX“ and “CH1 TX“ represent the L and R transmitted signals, while “CH2 RX“ and
“CH2 TX“ correspond to the L and R received signals, corresponding to channel 1 or 2
depending on the vu meters mode selected. For further information, see section “3.3.
VUMETERS menu” of this manual.
Each of the two VU meters is composed of 14 LEDs, of which the top three are red, the fourth
yellow (representing +0dB) and the rest green. Each one of the 14 LEDs represents 2dB; the
complete scale of each VU meter ranges from +6dB to -20dB.
2.1.7. Communication status control information.
There are two identical sections offering communication status information; each is associated
with a different communication channel (1 or 2). The buttons on the left correspond to
communication channel 1 and the buttons on the right correspond to communication channel 2.
Each section is composed of three elements.
-CALL button: pressing it allows you to make a call. For further information, see the
QUICK OPERATING GUIDE section of this manual.
-SYNC LED: to indicate the connection status. This LED has three statuses:
•Off: no connection.
•Red: trying to synchronize.
•Green: connected and synchronized.
-ON AIR button: enables full duplex communication, connecting the signal from the
selected input (analog or digital) with the output of the defined communication interface.

2.1.8. Headphones volume.
Potentiometer to control the output volume in the monitoring headphones. When this knob is
turned all the way to the left, the output audio level will be minimal or null; turning it all the way
to the right will produce the maximum output level. All the intermediate positions are possible.
NOTE: We recommend prudence when adjusting the volume, since excessively high levels can
be harmful to the listener’s health.
2.1.9. Monitoring headphones output.
¼” TRS Jack. Asymmetrical connection.

-The signals containing audio and synchronizing information (Channel 1 and Channel 2)
are compliant with the AES-3 standard. The signals that only contain synchronizing
information (Synchronism) are governed by the AES-11 standard.
-The synchronizing input signal can be used to change the sampling rate of the
AES/EBU output signal (set by default at 48 kHz).
-The synchronizing output signal will either repeat an external synchronizing input signal,
or will take the internal 48 kHz signal to the synchronizing input of other AES/EBU
equipment items. See menu description in section 3.1.3.3.
-When both of the two audio codec channels are used independently of each other, the
audio carried by each of them will be output through the connector corresponding to
channel 1 or 2.
Digital and analog outputs are always simultaneously availables.
2.2.4. GPIO connector.
General Purpose Inputs and Outputs connector. Configurable functionality. For further
information, see section “3.1.8.4. GPIOs configuration” of this manual.
NOTE: - The output signals are open collector active-low.
- The input signals are opto-coupled with internal 2.2Kohms resistor. They are
active-high.
The connector is a DB15 female type, with the following pinout:

2.2.5. Interfaz X.21/V.35.
DB25 physical connector.
DB25 connector pinout identification
Allows an external terminal adapter (TA) to be connected at speeds of 64/128/256 kbps. Two
types of TA can be used:
•V35 (V11) interface: Uses unbalanced asynchronous control signals, while the
synchronous clock and data signals are balanced.
•Interface which, at the physical level, is compatible with X.21 / RS422 protocol levels.
The pin-out detail and the signals available in the DB-25 connector are the following:
Pins 4 and 5, equivalent to RS232 RTS and CTS signals, are strapped internally. The AEQ
PHOENIX STRATOS can be configured to define whether the DCD signal will manage
communication (DCD CONTROLLED) or, on the contrary, the connection will be without DCD
management (PERMANENT). In the latter case, it will only be necessary to connect the six
shaded signals to establish the connection to the terminal adapter.
CAUTION:
Disconnecting the V.35 interface while the equipment is powered up could cause
internal damage.
To connect the AEQ PHOENIX STRATOS with an external V35 Terminal Adapter, you will need
to search in the TA user's manual for the exact pinout matches.
Because the TA equipment currently on the market has a great variety of connectors, AEQ
cannot provide details of all the possible connections. The following table shows, as an
example, the connection to an ISO-2593 standard terminal adapter in an MRAC-34 connector.

Some external terminal adapters are configurable. In this case, you will need to ensure that they
have these parameters:
•64kbps, 128kbps or 256kbps
•Synchronous
•CD Forced (ON)
•Ignore DTR
2.2.6. COM connector.
In IP mode, allows you to connect an external equipment (a PC, for instance) in order to
transmit and receive auxiliary data in a transparent way. An ancillary data channel at 9600,
19200 or 38400 bauds is supported that is transmitted over IP, independently of the audio
stream. Only one auxiliary data stream can be used, so it has to be assigned to one of both
codec channels.
In ISDN mode, a data channel at 9600 bps is supported in some MPEG-2 encoding modes.
Data transmission is performed according to RS232 protocol on a DB9 female connector. A
male-female cable must be used to connect the codec to a PC.
The active pins at the port are:
PHOENIX PC
TX 2 2
RX 3 3
GND 5 -- 5
Note that hardware flow control must be disabled at the PC
2.2.7. Ethernet port.
PHOENIX STRATOS is equipped with an Ethernet port. Using this Ethernet port will enable you
to connect the unit via IP to a LAN or WAN network and send audio over it. This port is also
used to configure and manage the unit from one or several PCs using the remote control
software.
Please consult ”AEQ ControlPHOENIX” application manual.
Physically, the connector is RJ45 10/100 BT, with the following pinout.

2.2.8. ISDN port.
According to the UIT-T, the Integrated Services Digital Network (ISDN) can be defined as a
network that has evolved from the Integrated Digital Network (IDN), and which provides end-to-
end digital connections to deliver a wide range of services, both voice and other types, and
which users access through a set of standardized interfaces.
It can thus be said that it is a network that is an outgrowth of the existing telephone network and
that, because it offers end-to-end digital connections, enables the integration of a multitude of
services in a single access, regardless of the nature of the information to be transmitted and of
the terminal device that generates it.
The connector employed is a standard RJ45 for the S interface and a standard RJ11 for the U
interface.
2.2.9. Power supply.
Mains input connector(s), including fuse and fuseholder.
Power supply: universal 90 - 240 V AC, 50-60Hz. 15 VA. IEC 3 pin connectors
The unit can include two internal power supplies, one of them working as redundant of the other
one.
