General Information
We, at DEVA, are enterprising, extremely driven and hardworking professionals, passionate
about what we do. Our expertise built on almost two decades of work in the broadcasting industry
inspired us to enter a whole new level of prociency, where technology and innovation work
together in a critical importance.
It was the real-world know-how of the broadcasting equipment that led DEVA in every step
of DB6000’s process of creation. It stands for cutting-edge design which meets cutting-edge
engineering. Containing a combination of features with no equal on the market, this audio processor
was built to obtain the perfect balance between power and performance.
By continuously developing new features and capabilities for our devices, we have managed to
enhance the DB6000 even more by integrating a DSP-based Stereo encoder assures an extremely
precise MPX Signal with advanced peak control and two independently congurable composite
MPX outputs. We have also added a feature never incorporated in an audio processor of this price
class before – the built-in IP Audio player supporting MP3 and PCM audio formats. Another
complimentary feature is the fully dynamic RDS/RBDS encoder.
The ultra-low latency DSP based design guarantees the broadcasters control over the most
important sonic parameters and assures clean, artifact free audio. The processing includes dual
stage wideband AGC with “intelligent gating”, multiband adjustable range equalizer, sophisticated
multiband peak limiter and advanced distortion controlled pre-emphasized nal clipper. Thus,
DB6000 will guarantee you perfect sound quality, regardless of the source material.
DB6000 combines unique merits contained in a single product, Fallback function included. If
silence in the main (default) audio input is detected, the DB6000 will automatically switch to the
fallback input, which can be any of the ones utilized by the device. Most importantly, DB6000 is
the industry’s rst audio processor to have an independent back-up audio source – fresh audio will
always be delivered by the built-in audio player. An e-mail notication will be sent immediately
upon change in the main audio input, thus, allowing your technical support team to react on the
very instant. The back-up content is easily updated via any PC, using standard FTP client. The
fallback function works the other way round-when the signal at the default input is restored the
DB6000 will automatically switch back to it. All silence sense parameters are user-dened.
As all DEVA products are designed with the idea of user friendly operation, the DB6000 comes
with a very clean, intuitive and well-organized user interface. It allows easy setup and full control
via the front panel and remote control access via TCP/IP. The HTML 5 based WEB interface
allows the unit to be accessed remotely through iOS, Android or any other mobile device.
Make use of the extensive set of factory presets of the device, optimized for popular radio
formats and several user-dened presets. Thanks to DB6000’s great processing power not only
the music, but also the speech will be enhanced to perfection. An exceptionally clean audio is
invariably achieved without compromise, at an affordable price.
DB6000 is the perfect combination of exibility and reliability to meet the most demanding
broadcasters’ requirements.

Before you start
SAFETY WARNING
• The servicing of electronic equipment should be performed only by qualied personnel;
• Before removing the covers DB6000 must be switched off 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.
ATTENTION: DB6000 has an internal Lithium battery. Do not try to re-charge this battery!
Please contact us for detailed instructions in case the battery should be changed.

OPERATING RECOMMENDATIONS
For normal operation of DB6000, we recommend following the instructions listed below.
• Install the unit in places with good air conditioning. DB6000 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;
• Locate the device away from abnormally high RF elds;
• Use only checked power supply cables. We strongly recommend the usage of shielded
cables;
• Connect DB6000 only to reliable power supply sources. 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;
• For the normal remote operation of the unit, connect DB6000 to a good quality Internet
connection;
• For the normal operation of DB6000, check if the network settings past through all the
required data traf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!
IT IS VERY IMPORTANT that the “Product Registration Card” on page 66 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 (RFI)
Although we have made provision for DB6000 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 DB6000 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 DB6000 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. Apply inward pressure to insert the cap in.
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 MPX OUTPUTS of the DB6000 are 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.

DB6000 Location
The best location for DB6000 is as near as possible to the transmitter, so that its stereo encoder
output can be linked to the transmitter through a circuit path. If this conguration is not possible,
the DB6000’s AES3 digital audio output can be fed through an all-digital, uncompressed path to
the transmitter exciter.
The usage of left and right analog audio outputs is recommended in the situations when the
stereo encoder and exciter are under the jurisdiction of an independent transmission authority, and
the programming agency’s jurisdiction ends at the interface between the audio facility and the link
connecting the audio facility to the transmitter. (The link might be telephone / post lines, analog
microwave radio, or various types of digital paths.)
Source Material Quality
The DB6000 is designed to achieve perfect sound quality, regardless of the source material.
Though, it is very important that the source audio to be as clean as possible, as upon processing the
