6-2 TECHNICAL DATA ORBAN MODEL 9400 Low-Pass Filter (processing for analog modulation): 4.5, 5.0, 5.5, 6.0, 6.5, 7.0, 7.5, 8.0, 8.5, 9.0, or 9.5 (NRSC) kHz as set by user. Unit can be set up to comply easily with ITU- R and NRSC spectrum masks. Filter can be set to be –0.1 dB, –3.0, or –6.0 dB down at the edge of the passband, trading off ringing against brightness. Low-Pass Filter (processing for digital modulation): 15 kHz. High-Pass Filter (processing for analog modulation): Constrained by user settable fifthorder “quasi-elliptical” highpass filter to 50, 60, 70, 80, 90, or 100 Hz. All filters have equal-ripple (Chebychev-like) passbands, and 25 and 35 Hz notches for transmitter protection. High-Pass Filter (processing for digital modulation): 1 Hz, not user-adjustable. Processing Topology: The stereo enhancer and two-band AGC are common to the analog and digital processing chains. The processing path splits after the AGC. The analog path receives equalization, five-band compression, distortion-controlled and -canceled clipping, overshoot compensation, and transmitter equalization. The digital path receives equalization, five-band compression, and look-ahead limiting. The parameters of the equalizers, five-band compressors, and peak limiters in the two paths are separately and independently adjustable. Processing Delay (processing for analog modulation): approximately 17 ms. Processing Delay (processing for digital modulation): approximately 24 ms. Any output can be switched to emit a monitor signal with 5 ms. delay. This signal contains the output of the five-band digital-channel compressor/limiter. Delay Difference between Analog AM and Digital Processing Chains: Fixed at 5.778 ms, regardless of processor control settings. Installation Analog Audio Input Configuration: Stereo. Impedance: >10k load impedance, electronically balanced 1 . Nominal Input Level: Software adjustable from –9.0 to +13.0 dBu (VU). Maximum Input Level: +27 dBu. Connectors: Two XLR-type, female, EMI-suppressed. Pin 1 chassis ground, Pins 2 (+) and 3 electronically balanced, floating and symmetrical. A/D Conversion: 24 bit 128x oversampled delta sigma converter with linear-phase antialiasing filter. Converter outputs 64 kHz sample rate, which the 9400 then decimates to 32 kHz in DSP using an ultra-high-quality image-free synchronous sample rate converter. Filtering: RFI filtered, with high-pass filter at 0.15 Hz (–3 dB). Analog Audio Output Configuration: Two stereo pairs, capable to driving two transmitters. 1 No jumper selection available for 600. Through-hole pads are available on I/O module for userinstalled 600 termination.
OPTIMOD-AM DIGITAL TECHNICAL DATA 6-3 Source Impedance: Electronically balanced and floating outputs simulate a true transformer output. Because of the built-in third-order EMI suppression filter, the source impedance is 351. Loading the output with 600 will decrease the output level by 4.0 dB compared to a high impedance (bridging) load and will reduce the maximum available output level by 4.0 dB. A software switch in Analog Output screen allows the output level calibration to be set for a bridging or 600 load. Load Impedance: 600 or greater, balanced or unbalanced. Termination not required or recommended. Output Level (100% peak modulation): Adjustable from –6 dBu to +20 dBu peak, into 600 or greater load, software-adjustable. Signal-to-Noise: >= 90 dB unweighted (Bypass mode, de-emphasized, 20 Hz–9.5 kHz bandwidth, referenced to 100% modulation). L/R Crosstalk:
