General Information

DEVA’s DB8008 is a exible and reliable tool, designed by our engineers specically with
the aim of solving one of the most signicant problems in the radio industry – the one of radio
silence. DEVA’s smart and highly practical solution detects signal loss and immediately switches the output to one of two alternative built-in backup players – MP3 or IP Audio. As an additional advantage, it also allows for easy integration into the existing setups of a single station and large radio networks alike.
The MP3 backup audio les and playlists can be uploaded to the device using any FTP client,
making this model not only efcient but also easy to use. The audio storage capacity of the unit is
an impressive 2GB for over 24 hours of audio playback without repetition. Moreover, the backup sources priority is selected by users themselves.
The DB8008 features a fully DSP-based core, professional AES/EBU digital audio inputs and outputs, and additionally allows for TCP/IP remote monitoring and control via SNMP and the WEB Interface, which means that the device can also be used for local content or regional advertisement
spots. Another option provided by the model is the alert notications via email, SNMP or analog
opto-coupled outputs in case of signal loss.
Developed to provide users with a tool for an infallible and constant audio feed, the DB8008 is trademark DEVA device offering a simple and subtle solution to the problem of radio silence.

Before you start

MAINS VOLTAGE SELECTOR

Unless specically requested at time of order, the DB8008 is set at the factory for operation
from 230V, 50/60Hz AC mains. To change the mains voltage for 115V operation, rst remove the
top cover of the unit. A clearly marked slide switch is next to the AC mains connector on the device circuit board. With power disconnected, use a small screwdriver to change the setting from 230V to 115V.
230V
115V

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

OPERATING RECOMMENDATIONS

For the normal and reliable operation of the DB8008 device we recommend to follow the next
list of instructions:
• Please, install the unit only in places with good air conditioning. The unit has been designed for operation within an ambient temperature range extending from 10 to 50°C. But because
adjacent, less efcient equipment may radiate substantial second-hand heat, be sure that the equipment rack is adequately ventilated to keep its internal temperature below the specied
maximum ambient. When installing, leave a clearance of at least 1 cm around the equipment to allow air to pass freely.
• We do not recommend installation in rooms with high humidity, dusty places or other aggressive conditions.
• Although it is expected that a DB8008 will be installed close to exciters (or transmitters of even higher-power!), please practice reasonable care and common sense in locating the unit
away from abnormally high RF elds.
• Please, use only already checked power supply cables and sources. The shielded cables
usage is strongly recommended.
• We strongly recommend connecting the device only to reliable power supply sources. In case of unstable power supply, please use UPS (Uninterruptible Power Supply).
• Please, use the device only with placed top cover to avoid any electromagnetic anomalies which may cause problems of the normal functionality of the unit.
• Please, connect DB8008 only to good quality Internet connection. This is very important for the normal remote operation of the unit.
• Please, check if your network settings pass through all the data trafc required for the normal
operation of the DB8008 unit.

RADIO FREQUENCY INTERFERENCE (RFI)

Although we have anticipated DB8008 installation in the immediate proximity of broadcast
transmitters, please do practice some care using the unit away from abnormally high RF elds.

Tel: +359 56 820027, Fax: +359 56 836700

Unpacking and Inspection

IT IS VERY IMPORTANT that the Warranty Registration Card found at the front of this
Manual be completed and returned. Not only does this assure coverage of the equipment under terms of the Warranty and provide a means of tracing lost or stolen gear, but the user will be sent
specic SERVICE OR MODIFICATION INSTRUCTIONS issued by DEVA Broadcast Ltd.
As soon as the equipment is received, inspect carefully for any shipping damage. If damage is
suspected, notify the carrier at once, and then contact DEVA Broadcast Ltd.
We recommend that you retain the original shipping carton and packing materials, just in case return or reshipment becomes necessary. In the event of return for Warranty repair, shipping damage sustained as a result of improper packing for return may invalidate the Warranty!

Mounting

RACK REQUIREMENT

The DB8008 mounts in a standard 19-inch equipment rack and requires only 1¾ inches (1U) of
vertical rack space. The use of plastic washers is recommended to protect the painted nish around
the mounting holes.

HEAT DISSIPATION

Consuming less power than the light in a refrigerator, the DB8008 itself generates negligible
heat. The unit is specied for operation within an ambient temperature range extending from freezing to 120°F/50°C. But because adjacent, less efcient equipment may radiate substantial
heat, be sure that the equipment rack is adequately ventilated to keep its internal temperature
below the specied maximum ambient.

APPENDIX B

DOWNLOAD/UPLOAD FILES VIA FTP

In order for a connection to be established the following setting should be applied:
1. FTP Server Settings
The built-in FTP Server has four important parameters that should be congured: Command
Port, Data Port, User name and Password. These parameters are to be used in the FTP client’s
connection conguration. Further information on how to change the FTP Server’s settings and
their respective default values can be found in the device’s User manual.
WE RECOMMEND the usage of FileZilla (https://lezilla-project.org). This is a widespread
open source software distributed free of charge, hence available for downloading from the Internet.
NOTE: The FTP Server can manage only one connection at a time. TheFTP Server works in
Passive mode. Hence, the FTP Client should also be set in passive mode.
2. IP Router and Port Translation Settings
If the connection to the device is made through a Network address translation (NAT) router or
rewall, the port forwarding feature of the router should be congured. The port forwarding is usually set in the rewall section of the router’s menu. As each router has different port forwarding procedure, we recommend you to refer to its complete manual. To allow proper data ow through
the router, the FTP Command and FTP Data ports should be open.
NOTE: The FTP port numbers to be used in the port forwarding feature conguration can be
found in the device.

3. Example of FTP Client (FileZilla) Settings
In some cases, FileZilla’s “Quick connect” feature is not able to connect with the DEVA unit. That is why we recommend the device to be assigned in the program manually.
Enter the FTP Client and go to: File> Site manager> New Site. A dialog box requiring obligatory information about the device will appear. Fill in the needed information and press “OK”.
Select “Transfer Settings” sub-menu and apply the settings as shown below:
