General Information
DB9000-RX is a professional and highly reliable IP to Audio decoder. It comes with an HTML5
based web server for device management and Ethernet to a RS-232 Redirector, enabling quick
integration of the existing audio systems to the Internet. The device is available with an optional
fully digital, DSP-based Stereo & RDS Encoder Module.
Supporting the compulsory for this high class equipment HE-AAC versions 1 and 2, MPEG-1
Layer 3 compressed audio streams and PCM uncompressed stream, the DB9000-RX can be used
for a scope of professional audio applications: Broadcast, Internet Radio, Studio to Transmitter
Link and VoIP.
The powerful DSP processor and either digital or analog output signals allow for the decoding
process to be accomplished in real time which makes the device compatible with any online radio
system, including Icecast and Shoutcast. Another impressive addition to DB9000-RX features is
the low latency Real Time Protocol (RTP) connection support.
Along with its main IP audio source DB9000-RX comes with several IP audio sources and a
built-in MP3/AAC Backup Audio Player for higher stability. The device has a built-in FTP server
and 2GB SD card where the audio content for the MP3 Player is recorded. The backup audio les
can be easily managed anytime remotely via any FTP client.
If the audio signal of the main source disappear, the device will switch to the rst available
IP audio backup source. If none of the audio backups are available then the MP3 Player starts.
While when the main audio signal is recovered, DB9000-RX will automatically switch back to it.
Depending on your needs, the sequence of the backup audio sources can be easily changed.

Safety Warning
ALWAYS OBSERVE THE SAFETY PRECAUTIONS.
Careful observance of the safety precautions will help prevent physical injury, damage of the
equipment, and extend the equipment life.
• The servicing of electronic equipment should be performed only by qualied personnel;
• Before removing the covers the unit must be switched o and the mains cable unplugged;
• When the equipment is open, the power supply capacitors should be discharged using a
suitable resistor;
• Never touch the wires or the electrical circuits;
• Use insulated tools only;
• Never touch the metal semiconductor. They might carry high voltages;
• For removing and installing electronic components, follow the recommendations for
handling MOS components.
• Do not remove the factory sticker from the equipment. It contains information as regards
the name, serial number and MAC address of the device.
• To join the equipment to the mains supply, use the power cord purchased with the equipment.

Operating Recommendations
To ensure normal operation of the DEVA unit, we recommend following the instructions listed
below.
• Install the unit in places with good air conditioning. The unit is designed to operate within the
ambient temperature range of 10 to 50°C. The equipment rack should be ventilated in order
for the device to keep its internal temperature below the maximum ambient temperatures;
• We do not recommend installation in rooms with high humidity, dusty places or other
aggressive conditions;
• Although the device is intended to be installed closed to exciters or transmitters, we do
recommend the device to be located away from abnormally high RF elds.
• Use only checked power supply cables. We strongly recommend the usage of shielded
cables;
• Connect the DEVA unit to reliable power supply sources only. In case of unstable power
supply, please use Uninterruptible Power Supply (UPS);
• Use the device only with its top cover on to avoid electromagnetic anomalies. Otherwise,
this may cause problems with the normal functionality of the unit;
• To ensure normal remote operation of the unit, make sure to connect the device to a good
quality Internet connection;
• For the normal operation of your DEVA device, check if the network settings past through
all the required data trac.

Unpacking and inspection
Upon receipt, the equipment should be inspected for possible shipping damages. If such are
found or suspected, notify the carrier at once and contact DEVA Broadcast Ltd. The original
shipping carton box and packing materials should be kept for possible reuse, in case of return for
Warranty repair, for example. Shipping damages as a result of improper packing for return may
invalidate the Warranty!
The packing material (plastic bags, polystyrene, nails, etc.) must never be left within reach
of children, as these items are potential sources of danger.
IT IS VERY IMPORTANT that the “Product Registration Card” included in the Manual be
completed accurately and returned. This will assure coverage of the terms of the Warranty and it will
provide a means of trace in case of lost or stolen equipment. In addition, the user will automatically
receive SERVICE OR MODIFICATION INSTRUCTIONS from DEVA Broadcast Ltd.
Mounting
RACK REQUIREMENTS 1U
The unit mounts in a standard 19-inch equipment rack and requires only 1¾ inches (1U) of
vertical rack space. In order the painted nish around the mounting holes to be protected, the use
of plastic washers is recommended.
RACK REQUIREMENTS COMPACT UNITS
Our customized 1U 19-inch rack accessory provides a professional mounting option for up to
three compact size DEVA units. It is made of milled aluminum and nished in black powder coat.
Two extra blanking panels and set of mounting screws are provided with each rack bracket kit.
STAND-ALONE DEVICES
DEVA’s stand-alone units (Radio Explorer series, BandScanner series, DVB Explorer) do not
require additional tools or installation brackets.

AC Mains Power
FUSE HOLDER
The fuse holder is placed inside the unit, next to the voltage selector. Apply downward pressure
and pull the cap outward to access the 5mm mains fuse. The reverse process will release the cap.
MAINS VOLTAGE SELECTOR
Before connecting the AC Power, make sure that the internal Power Switch is in accordance
with the mains supply at your location. The Power Supply Factory Settings are:
- 100 - 240 VAC
- 1 Amp Fuse
CAUTION: Permanent damage will result if improper AC supply voltage is applied to the
device. The warranty DOES NOT cover damages caused by applying improper supply voltage or
usage of improper fuse.
POWER CORD
The detachable IEC-type power cord is supplied with the unit. The individual cord conductors
may be color-coded in either of two ways:
1) In accordance with US standards:
BLACK = AC “HOT”
WHITE = AC NEUTRAL
GREEN = EARTH GROUND
2) To European CEE standards:
BROWN = AC “HOT”
BLUE = AC NEUTRAL
GREEN/YELLOW = EARTH GROUND
GROUND LOOPS
Because the unbalanced INPUTS/OUTPUTS of the device are chassis-ground-referenced, a
mains frequency or INPUT/OUTPUT ground loop could be formed between the input or output
cable shield grounds and the AC power cord ground. A ‘ground-lifting’ AC adapter may help in
this situation, although the chassis must be properly grounded for safety purposes. In general, the
equipment being installed in a rack will satisfy the safety requirement.

MAINS VOLTAGE SELECTOR LOCATION
Unless specically ordered for export shipment, the DB9000-RX is set at the factory for
operation from 115V/230V, 50/60Hz AC mains. This can be conrmed by checking the voltage
selector inside the unit. To change the mains voltage, rst remove the top cover of the unit. A
clearly marked slide switch is next to the AC mains connector on the encoder circuit board. With
power disconnected, use a small screwdriver to set the switch for 115VAC or 230VAC operation.
Be sure to install the appropriate fuse, DB9000-RX is equipped at the factory with 1A fuse.

Getting Started
In order for the normal operation of the DB9000-RX to be guaranteed, you will need fulll the
following conditions:
1. Standard Ethernet 10/100M connection;
2. Correctly assigned Network conguration and device settings.
To make sure that all the conditions are fullled please, follow the instructions below.
CONNECTION
1. Install the unit on its operation place;
2. Using the provided power cable, connect the unit to the power supply network;
3. Connect the antenna cable to the RF antenna input connector located on the rear panel of
the device;
4. Connect the DB9000-RX to the TCP/IP network using direct network cable;
5. IF GSM OPTION IS SUPPORTED - Using the connection cable provided, connect the
optional GSM modem. In order for better GSM network coverage to be achieved, please
select proper place for the GSM antenna.
NOTE: The GSM antenna must be installed far enough from the monitoring devices. The
GSM modem radiates RF signal that may cause spurious emissions that will may interfere with the
accuracy of the measurements.
