General Information
The new DB3012 – DAB/DAB+ Radio & IP Audio Condence Monitoring Receiver is the
ultimate monitoring tool – pace-setting, dependable and sophisticated. Designed to meet the latest
trend in the broadcasting equipment industry – the Digital Audio Broadcasting Service, this product
is your solution for near CD-audio quality, user-friendly operation and a wide range of outstanding
features with the trademark DEVA guarantee of quality and functionality.
Recently, radio broadcasting has been developing at a rapid rate bringing listeners audio
with increasing clarity. One of the distinctive trends in the industry has been the Digital Audio
Broadcasting Service (DAB) and DEVA is providing the market with a tool to fully meet the
ETSI EN 300 401 DAB standard. Incorporating this latest trend and its own know-how in
producing technological innovation, DEVA is proud to launch the DB3012, equipped with a high-
performance 3-way speaker system that ensures outstanding sound reproduction. The unit supports
AAC, AAC+, MP3, RTP and PCM IP audio codecs and is fully compatible with the most popular
media platforms, Icecast and Shoutcast included. To facilitate its use, our engineers have created a
tool that can simultaneously monitor both the DAB and the online stream.
The highly-selective DSP-based tuner of the device allows the DAB/DAB+ and online
stream of the station to be selected, monitored and listened to through the top-quality speakers or
headphones. The signal is monitored and logged, while the DB3012 also measures and stores for
future analysis the DAB signal quality and the Left & Right Audio level values. A standard FTP
client ensures easy download of the collected data. Furthermore, to bring you uninterrupted audio
broadcast, the DB3012 provides local alarm options and online notications via rear-panel alarm
GPOs, E-mail and SNMP ver. 2C, in case of audio loss or change in the DAB signal and the Left
and Right Audio Levels. This allows for a quick response on the part of your maintenance staff so
that prolonged signal loss is prevented.
One of the dening characteristics of each DEVA product is the useful combination of technical
capabilities and easy control and set-up. Your DB3012 unit can be programmed through the front-
panel menu, while remote access is granted through your PC, tablet or smart phone via a standard
web browser; iOS and Android devices are also supported. A click is all that is needed for you to
access the WEB interface so that you can listen to the DAB/DAB+ Station and online streams. A
high-resolution OLED graphical display and three ultra-bright LED bar-graph indicators allow for
easy reading of the main signal parameters. The front panel menu and the set of four soft buttons
provide easy navigation through the menus and quick access to the device’s functions.

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!
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.
RADIO FREQUENCY INTERFERENCE
Although we have made provision for DB3012 installation in the immediate proximity of
broadcast transmitters, please do practice some care using the unit near abnormally high RF elds.

Mounting
RACK REQUIREMENTS
The DB3012 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.
HEAT DISSIPATION
Having very low electricity consumption, the DB3012 itself generates negligible heat. The
unit is intended 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.

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 and the fuse rating
are in accordance with the mains supply at your location.
DB3012 Power Supply Factory Settings are:
- 100 - 240 VAC
- 1 Amp Fuse
CAUTION: Permanent damage will result if improper AC supply voltage is applied to DB3012
device. Your warranty does not cover damages caused by applying improper supply voltage, or use
of an 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 RF INPUT of the DB3012 is chassis-ground-referenced, a mains
frequency or RF 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 well remedy such a situation,
although the chassis somehow must be returned to earth ground for safety. Generally, being
screwed-down in the equipment rack will satisfy the safety requirement.
