Orban Optimod - PC1101


PCIe Card Microsoft Windows® Audio Processing Card for Professional Broadcasters / Stations

The Microsoft Windows Orban Optimod-PC 1101e Professional Audio Processing Card for PCIe Bus Systems offers on-board transmission-quality, dedicated digital signal processing for audio processing, mixing, and routing.


Optimod-PC processing is more reliable than software-based processors that run natively on the computer's CPU because the operating system can never deprive the Optimod-PC processor or mixer for processing cycles.


This allows more instances of an encoding application to run flawlessly in the computer's CPU, providing higher reliability and lower operating costs because fewer CPUs are required for large operations.

Drivers are now available for 32-bit and 64-bit versions of Windows XP, Vista, 7, 8.1, and 10.

-Low IM forecast limiter effectively limits spikes while ensuring low bit rate codecs work optimally without overhead.

-Precisely control maximum levels to avoid overmodulation or codec overload. The peak limiter can be configured to control "flat" transmission channels or channels previously emphasized at 50 μs or 75 μs.

-Although primarily oriented towards "flat" media, Optimod-PC can also provide a pre-emphasis limitation for the two pre-preferred 50 μs and 75 μs standard curves. This allows you to protect pre-emphasized satellite uplinks and similar channels where protection limitation or light processing is required. Because its processing topology is more effective with "flat media", Optimod-PC cannot provide extreme volume for pre-emphasized radio channels. Use one of Orban's Optimod-FM processors for this application. For analog television with FM audio carrier (s), use Optimod-TV 8382.

Optimod-PC's dual-mono architecture enables completely separate mono programs to be processed in 5-band mode, facilitating operation in two languages. In this mode, both processing channels operate using the same processing parameters (such as release time); you cannot adjust the two channels to provide different processing textures.

- The balanced analog input with 24-bit A / D converter is always active, mixing with the two digital inputs.

-A balanced analog monitor output with 24-bit D / A converter.

-Two AES3 or SPDIF digital inputs with high-quality sample rate conversion allow two asynchronous digital sources to be mixed: Ideal for network operations using commercial insert / local ad.

-The second digital input also accepts AES3 home sync, synchronizing the AES3 output sample rate with the sync input sample rate.

-Digital inputs accept any sampling rate from 32 to 96 kHz without manual configuration.

-Two AES3 digital outputs at 32, 44.1, 48, 88.2 or 96 kHz sampling rate. In software v1.0, they output identical signals.

-Two Wave inputs from any PC audio application (such as a playback system) that can output standard Wave audio. Audio from Wave inputs can be mixed and changed with Optimod-PC hardware inputs. Because there are two inputs, you can operate two PC applications simultaneously and mix and / or change their Wave outputs within Optimod-PC, such as commercial / content insertion systems.

-Two Wave outputs to any PC audio application that can record or encode.

-Optimod-PC controls the audio bandwidth as needed to accommodate the transmitted sample rate, obviating the need for extra and extra anti-aliasing filters on later equipment.

Optimod-PC's high-frequency bandwidth can be instantly changed (usually in 1kHz increments) between 10.0kHz and 20kHz. 20 kHz is used for the highest quality systems. 15 kHz meets iBiquity® HD-AM system requirements using a 44.1 kHz system input sample rate. (The 15 kHz codec bandwidth can also help low bit rate loss codecs sound better than when fed with full 20 kHz bandwidth audio.) The 10 kHz bandwidth meets the requirements of auxiliary DAB transmissions using a 24 kHz sample rate.

-Internal processing occurs at a sampling rate of 48 kHz and an audio bandwidth of 20 kHz.
