Page 16: 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;... -
Page 17: 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. -
Page 18: Mounting
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 finish around the mounting holes to be protected, the use of plastic washers is recommended. -
Page 19: Ac Mains Power
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. -
Page 20: Db6000 Location
E-mail: office@devabroadcast.com ,Web: www.devabroadcast.com 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 configuration is not possible, the DB6000’s AES3 digital audio output can be fed through an all-digital, uncompressed path to... -

Basic Setup/Connection Example REFERENCING ANALOG AND DIGITAL INPUTS LEVEL In order for the proper work of DB6000 to be guaranteed, and due to the variability of the signal levels, the right reference levels of the digital and analog inputs should be set. -
Page 24: Referencing Analog And Digital Outputs Level
Level, the output Ref. Level determines the amplitude of the respective output, which corresponds to 0dBFS. The value is set depending on the level requirements of the device connected to DB6000’s digital output. Having the proper Ref. level set at the output of the audio processor, guarantees that the signal amplitude at the input of the subsequently connected device will be within the required optimal range. -

Page 29: Loop Through
E-mail: office@devabroadcast.com ,Web: www.devabroadcast.com Loop through The output of the DB6000 is wired directly to the PILOT/MPX IN of the SmartGen 6.0. The output of the RDS encoder will be connected to the composite/MPX input of the FM transmitter. This connection is not recommended, because the composite signal/MPX passes through the RDS encoder, and the transmission of the program will be interrupted in case of failure of the RDS encoder. -
