Orban Optimod-FM 5500 Digital Audio Processor

OPTIMOD-FM 5500 will be five bands and two bands OPTIMOD handle set in a single rack unit package , and the best price available to you, instead of the OPTIMOD-FM5300 5500 and 2300 , to provide cooling to run in the new package two processors.

High quality is the 5500 's advantage - no matter how the format and the source material , the audience can bring a beautiful , professional -quality results. Excellent versatility audio processor allows you to mediate texture to brand your sound you make signature sound produced on audio clips and always consistent . Branding can promote business development in OPTIMOD inhibitory aspects of your brand voice , the other processors can not match.

5500 can also be used independently of excellence stereo codec with low latency of 2ms , left / right , and composite band overshoot limit all domains . When used in this mode, the 5500 includes a pre -emphasis to be perceived by HF and peak limiting control fully functional FM audio processor ( e.g. ORBAN 8600 ) is driven ( typically by STL). In both modes , the stereo encoder 5500 and help clear the perfect limit the peak transmission signal regardless of the amount of the composite restrictions , has all the sub- carrier spectrum protection and RDS / RBDS.

5500 is used ORBAN Flagship OPTIMOD-FM8600 processing origin and broadcast in the network processor requires a transmitter to eliminate each STL overshoot ( using a separate stereo encoder 5500 Mode ) and / or processed locally inserted simultaneously ideal also eliminates network STL overshoots ( using 5500 audio processor / stereo encoder mode ) of the broadcasting company . In addition, any 5500 can be used as a stereo encoder with or without audio processing , making 5500 the two modes of government agencies and network broadcasters easier to manage their spare parts inventory .

In both modes , the built-in can be disabled ITU BS412 multiplex power controller , even the most stringent European government regulations, output 5500 can also be met.

5500 added a 10MHz frequency reference input enables stereo pilot tone frequency locked to the GPS or other high-precision frequency standard . This overlapping coverage area of the transmitter increases the frequency of a single network performance . Another new feature is the cooling operation and the use of energy-efficient switching power supply Freescale Semiconductor 's latest dual-core DSP chip technology .

Use 5500, your signature sound is just a preset sound. Easy single spin button to decrease / increase allows you to adjust based on market and competitive environment customize any factory preset , commercial cleaning products for processing . Full control allows you more flexible to customize your sound. If you are a backbone of treatment expert , you can plant programmers like ORBAN explore advanced controls to fine-tune the preset.

This versatility makes 5500 to become the optimal choice for any sound format. Its five -band processing for any pop music is ideal . Regardless of your choice, 5500 optimization techniques for a given level of subjective quality ensures significantly increase the average modulation and coverage.
