1 Advanced Processing for FM Stations with High Aspirations & Modest Budgets!

2 Orban’s OPTIMOD-FM 2200 has become renowned in the broadcast industry for delivering that big Optimod sound at a slimmed-down price. The new OPTIMOD-FM 2300 builds on the 2200’s sound, adding stereo enhancement, more powerful equalization, anti-aliased clipping, composite limiting, and full remote control facilities. AES/EBU digital input and output is now standard, as is clock-based automation. Switching between “Two-Band Normal” and “Two-Band Purist” processing is now gap-free. OPTIMOD-FM

3 With the 2300, your signature sound is just a preset away. An easy, one-knob Less/More adjustment allows you to customize any factory preset, trading cleanliness against processing artifacts according to the requirements of your market and competitive environment. Full Control gives you the versatility to customize your audio further. 3 OPTIMOD-FM 2300

4 This versatility makes the 2300 work well with any format. The 2300’s optimized technology ensures unusually high average modulation and coverage for a given level of subjective quality. 4 OPTIMOD-FM 2300

5 The compact 1u form factor makes the 2300 at home in any rack, and its solid, competitive sound makes it an ideal choice for medium and small market stations, non-commercial and educational stations, and any other broadcasters whose aspirations exceed their budgets. 5 OPTIMOD-FM 2300

6 The 2300 is also the ideal choice for network broadcasters who process with Orban’s flagship OPTIMOD-FM 8400 at the network origination point and who need a processor at every transmitter to eliminate STL overshoots or to process local insertions. 6 OPTIMOD-FM 2300

7 The 2300’s superb stereo encoder and composite limiter help deliver a transmitted signal that’s always immaculately clean and perfectly peak limited, with full protection of sub-carriers and RDS/RBDS regardless of the amount of composite limiting. 7 OPTIMOD-FM 2300

8 The built-in ITU 412 multiplex power controller means that the 2300’s output meets even the most stringent European government regulations. In addition, strict 16 kHz band limiting ensures that the peak-limited left and right outputs can pass through 32 kHz uncompressed digital STLs without added overshoot — there is no need to use STLs having 44.1 or 48 kHz sample-rates. 8 OPTIMOD-FM 2300

9 Like its predecessor, the 2300 is remote controllable via eight programmable GPI ports. However, unlike its processor, the 2300 is equipped for remote control via RS232 serial or Ethernet ports, and comes with a full-featured remote control application that runs on Windows 2000 or XP. 9 OPTIMOD-FM 2300

10 The 2300 has an internal, DSP-based stereo encoder (with a patented “half-cosine interpolation” composite limiter operating at 512 kHz sample-rate) to generate the pilot tone stereo baseband signal and control its peak level. 10 OPTIMOD-FM 2300

11 The 2300 has a defeatable, patented multiplex power limiter that controls the multiplex power to ITU-R BS412 standards. Because this limiter closes a feedback loop around the audio processing, it allows the user to adjust the processor’s subjective setup controls freely without violating BS412 limits, regardless of program material. 11 OPTIMOD-FM 2300

12 A versatile real-time clock allows automation of various events (including recalling presets) at pre-programmed times. 12 OPTIMOD-FM 2300

13 Base sample-rate is 64 kHz in this mode. A high-accuracy ITU BS412 MPX Power Controller is available. 13 OPTIMOD-FM 2300 New Version 2 software now lets you use the 2300 as an ultra-high-quality stand-alone stereo encoder.

14 Phase-linear 15, 16 and 17 kHz lowpass filtering is available. Filter can be bypassed. An input overshoot limiter can remove overshoots caused by lossy codecs (like MP2) used in studio-to-transmitter links. A dual-mode, ultra-low-overshoot “Half- Cosine Interpolation” or hard composite limiter is available This is the same algorithm used in Optimod-FM OPTIMOD-FM 2300
