Summary

Audio Processor for Webcasting

Whether you are streaming audio from a fixed location or producing live events for the Internet, the 6200S takes the power of OPTIMOD to your webcast. It helps create a signature sound by adapting processing to the technical demands of the medium – offering you increased loudness, improved intelligibility and a consistent audio presentation. Delivering audio over the web means variable bandwidths. The 6200S optimizes the use of the bandwidth without compromising the performance of the perceptual encoders, giving you a polished, professional, competitive sound.

Technical Specification

Technical Specification

System

Frequency Response: ±0.1dB, 2-20,000Hz (Bypass mode).
Internal Filters: (4.0 to 11.5kHz in 500Hz steps), 12, 13, 14, 15, 20kHz provide anti-aliasing for any sample-rate and bit-rate combination.
Internal Sample Rate: 48kHz.
Internal Resolution: 24-bit fixed point (Motorola DSP56009).
Input/Output Resolution: 20-bit, limited by Analog Devices sample rate converters.
Peak Control Accuracy: If output samples are synchronous with internal samples, maximum overshoot of any output sample is 0.1dB. This is true at 48kHz output sample rate. If sample rate conversion after internal processing makes output samples asynchronous with internal samples, output samples can overshoot as much as 1dB (0.3dB typical).
Phase Response: All processing is linear-phase (constant group delay).
Internal Processing: Input -> Two-Band defeatable AGC -> Four-Band Equalizer -> Multiband Compressor -> Look-ahead Limiter -> Output.
Processing Structures: Three available: Five-Band, Two-Band, and Protect, selectable by mute-free crossfade.
Equalizers: 4 Eq. sections; Shelving Low Bass Eq.; Shelving Mid bass Eq.; bands Parametric Midrange Eq.; and High Frequency Eq.
Number of Factory Presets: 26, each with 19-step LESS-MORE control. Presets are fully customizable with FULL CONTROL.
Number of User Presets: 32 memory locations to save customized presets.

AD Conversion: 24-bit 128X oversampled delta sigma A/D converter with linear phase anti-aliasing filter.
RF Filtering: Effective 0.5-1000MHz.
High Pass Filter: 0.15Hz.

Analogue Audio Output (Monitor)

Note that this output is not intended to be used as a transmitter output, rather it is for monitoring. Nevertheless it has been designed for low noise, distortion, and overshoot and can drive an STL or transmitter in an analog plant. Peak control will not be as good as at the digital output because on-air samples will be asynchronous with peak-controlled internal samples. The source of this output is switchable between the peak limiter output and the multiband compressor output. Because most of the delay occurs in the peak limiter, this can make headphone monitoring much more comfortable for on-air talent.

Configuration: Stereo.
Source Impedance: 30 ohms, electronically balanced and floating.
Load Impedance: 600 ohms or greater, balanced or unbalanced. Termination not required or recommended.
Output Level: Fixed at +14 dBu peak, with MON OUT source set to “POST LIMiter.” Pre-limiter peaks up to +26 dBu possible. No output level adjustment control provided.
Signal-to-Noise: 90 dB unweighted signal-to-noise, 20Hz-20kHz (bypass mode).
Distortion: £0.01% THD (bypass mode), 20Hz-20kHz.
Connector: Two XLR-type, male, EMI-suppressed. Pin 1 chassis ground, Pins 2 (+) and 3 electronically balanced, floating and symmetrical.

Filtering: RFI filtered. Effective 0.5-1000MHz.

Digital Audio Input

Configuration: Stereo per AES/EBU-standard (AES3-1992), 20-bits resolution, software selection of stereo, mono from left, mono from right, or mono from sum (as source to use as a mono processor).
Sampling Rate: 32, 44.1 and 48kHz.
Connector: XLR-type, female, EMI-suppressed. Pin 1 chassis ground, Pins 2 (+) and 3 transformer balanced and floating, 110 ohms impedance.
Status Bits: Input channel status is ignored. Input User bits are optionally passed through to the output.
Input Reference Level: Variable within the range of -30 to -10dBFS (VU) in 0.5dB steps.
Filtering: RFI filtered. Effective 0.5-1000MHz.

Digital Audio Output

Configuration: Two-channel per AES/EBU-standard (AES3-1992).
Output Level Control: Peak level is adjustable from -20dBFS to 0 in 0.1dB steps. Controlled by software.
Sampling Rate: Internal free running at 32kHz ±10 PPM, 44.1kHz ±100 PPM, or 48kHz ±10 PPM, selected in software. Can also be synced to the AES/EBU SYNC input or the AES/EBU DIGITAL input at 32kHz ± 4%, 44.1kHz ± 4%, or 48kHz ± 4%.
Word Length: Selectable 20, 18, or 16 bit. Optional dither can be added, with level adjusted appropriate to word length. This is first-order noise-shaped dither. (i.e., white TPDF dither of peak amplitude equal to the quantizer step size with noise shaping spectral density of 6dB/octave.) It sounds substantially quieter than white triangular PDF dither but, in contrast to more extreme noise-shaped dither, it adds only 3dB unweighted noise by comparison to white PDF dither.
Sync: Internal free running or external per AES11. The “AES/EBU SYNC Input” is the primary source for external sync. The “AES/EBU Input” is an alternate source.
Connector: XLR-type, male, EMI-suppressed. Pin 1 chassis ground, Pins 2 and 3 transformer balanced and floating.
Status/User Bits: The channel status optionally supports the S/PDIF or AES/EBU formats. The user bits received from the “AES/EBU input” are optionally passed through to the output. The 192-bit block structure is used where prea ble “Z” indicates the start of block.
Jitter:
Less than 10ns rms.
Filtering: RFI filtered. Effective 0.5-1000MHz.

Digital Sync Input

Configuration: Used for synchronization of the Digital Output signal to an external reference provided at this input. Labeled “AES/EBU Sync Input.”
