ORBAN OPTIMOD-FM 5500i Digital Audio Processor
Optimod-FM 5500 puts the five-band and two-band Optimod processing in a separate rack unit package, and provides you with the best price, 5500 replaces the Optimod-FM5300 and 2300, provided in the new cooling run package The function of the two processors. High sound quality is the advantage of 5500 - no matter how the format and sound source materials can bring beautiful and professional sound quality. Excellent versatility allows you to mediate the audio texture of the processor to brand your voice, so that the resulting signature sound is always consistent on the clip and sound source. Branding can promote business development, and other processors cannot be comparable to it in the inhibitory of Optimod brand your voice. 5500 can also be used as an excellent independent stereocene decoder with a low reaching 2 ms delay, all overshoot restrictions on the left / right, and composite bands. When used in this mode, 5500 must be driven by a full-function FM audio processor (eg, an ORBAN 8600) that includes pre-sensing HF restrictions and peak controls (typically via STL). In both modes, the stereo encoder of 5500 helps to transmit clear and perfect limitations, regardless of the composite limit, all subcarriers spectrum protection and RDS / RBDS. 5500 is a broadcast company that uses ORBAN flagship Optimod-FM8600 and needs to have a processor at each transmitter to eliminate STL overshoot (using 5500 independent stereo encoder mode) and / or processing local insertion simultaneously. Also eliminates the ideal choice for broadcast companies that use the network STL overshoot (using 5500 audio processor / stereo encoder mode). In addition, two modes of 5500 can be used as a stereo encoder with or without audio processing, and the government agencies and network broadcasters are easier to manage their spare parts inventory. In both modes, the built-in canable ITU BS412 multi-channel transmission power controller, even the most stringent European government regulations, 5500 output can also be reached. A 10MHz frequency is added to the 5500, which allows the stereo conductive audio audio frequency to be locked to GPS or another high precision frequency standard. This increases the single frequency network performance of the transmitter overlapping area. There is also a new feature to cool the running energy-saving switching power supply and the latest dual-core DSP chip technology using Freescale Semiconductor. Using 5500, your signature sound is just a preset sound. Easy single spin buttons reduce / increase regulation allows you to customize any factory preset according to the market and competition environment, and conduct business cleaning for processing products. Fully control makes you more flexible and diverse to customize your sound. If you are a backbone expert, you can explore advanced controls like the programmer of the Orban factory to fine-tune the preset. This multi-function makes 5500 the optimal choice in any sound format. Its five-band processing is ideal for any pop music. Whether your choice is, 5500 optimization technology ensures significant increase in the average modulation and coverage for a given subjective quality level.
