The digital on-air audio processor provides universal transmitter protection and audio processing for FM broadcast. It can be configured to interface ideally with any commonly found transmission system in the world, analog or digital.<br>The Optimod-FM 5700 now offers the popular 8500 sound in a compact, cool-running 1U package. The 5700 provides stereo enhancement, equalization, AGC, multiband compression, low-IM peak limiting, stereo encoding and composite limiting.<br>The FM and digital media processing paths split after the 5700's stereo enhancer and AGC. There are two equalizers, multiband compressors and peak limiters, allowing the analog FM and digital media processing to be optimized separately.<br>The 5700 includes a ratings encoder loop-through connection. This allows a ratings encoder with an AES3 digital input and output to be inserted between the output of the AGC, before the analog-FM and HD processing paths split or between the output of the audio processing and the input to the stereo encoder. This keeps the audio level driving the ratings encoder as high as possible, minimizing the number of low audio level alarms that the ratings encoder generates.<br>The 5700 includes a full-featured RBS/RBDS generator at no additional charge. The generator supports dynamic PS. It can be controlled via the 5700 presets and an ASCII terminal server that can be connected to automation to support displaying title and artist.<br>The front-panel display includes a 2x40-character LCD and LED bargraphs that show all metering functions of the processing structure (two-band or five-band) in use. The metering is always visible while you are adjusting the processor. Navigation is by dedicated buttons, soft buttons (whose functions are context-sensitive), and a large rotary knob.<br>Ethernet connectivity is standard, as is an easy to use PC remote control application that runs on Windows XP and higher and that can control many 5700 units on a TCP/IP network. Additionally, programmable contact-closure (GPI) control plus ACSII terminal control via the 5700's RS232 serial and Ethernet ports together give you total freedom to interface the 5700 with your facility's remote control infrastructure, whatever it might be. SNMP support offers yet another way to control and monitor the 5700's operation via your network.
