AEROMAX 5.1-XL™ 10-Channel Television Audio Processor- Combining air-proven dynamics processing with stereo-to-5.1 surround sound upmixing, AEROMAX 5.1-XL features optional 5.1-channel Dolby® Digital (AC-3) encoding. Metadata is accepted and can be used alone or in combination with dynamic range processing. Built-in AutoMAX™ fixes the problem of two-channel audio mistakenly signaled as 5.1. Digital inputs for 5.1-channel network and two-channel local audio, plus dedicated analog and digital EAS inputs, full-time LtRt or LoRo output, stereo monitor output, and front-panel headphone connector.

AEROMAX-DTV™ Six-Channel Television Audio Processor- A fully integrated, entry-level unit for controlling loudness and ensuring stable audio imaging for 5.1-channel broadcasts, AEROMAX-DTV is based on the successful OCTiMAX 5.1 and combines air-proven dynamics processing to control program loudness with Hollywood-approved stereo-to-5.1 surround sound upmixing.

AEROMAX-TV™ Stereo Audio Processor- A dynamics unit for two-channel main plus SAP audio, or four mono channels of audio, AEROMAX-TV™ features CrowdControl™ Dialog Protection Processing to eliminate the "missing announcer" problem for stereo viewers prior to transmission without impacting sound quality for surround listeners.

Model LA-5448 High Density AC-3 Frame Synchronizer/Rate Shaper- Processes up to four AC-3 programs to re-synchronize to local AES reference, remove errors, and rate shape the outputs to a fixed data rate. Includes silent frame continuous output capability.

Model LA-5180 MetaMAX™ Series Metadata Framesync/Generator- Accepts external metadata via RS-485 serial or HD-SDI VANC, allows correction of incoming errors, re-writing of all parameters and reversion to fully adjustable internally generated values output via serial and HD-SDI. Can also be used as a stand-alone generator. Future available upgrades include web interface, DVB-ASI and compressed audio processing.

LAMBDA™ Professional Digital Audio and Metadata Monitor- Linear Acoustic Monitor for Broadcast Digital Audio enables monitoring of digital audio and metadata bitstreams through the entire broadcast
chain. Accepts both baseband and HD-SDI audio plus metadata, with Ethernet remote monitoring; optional Dolby® Digital (AC-3), Dolby® E and Linear Acoustic e2 (e-squared™) decoding.

StreamStacker-HD™ Multi-Program High Density Distribution System- Offering continuously variable efficiency adjustment to match each section of the delivery chain, StreamStacker-HD enables up to 16 channels of audio plus metadata to be carried via a single bit-accurate 20-bit/48 kHz AES pair.  Comprises the following pair of complementary units: 

Model LA-5173 StreamStacker-HD™ Encoder - Sixteen input, 1-RU encoder including AES and SDI (HD/SD) inputs and outputs, plus VANC and RS-485 metadata input. Future upgrades will include metadata monitoring, DVB-ASI support, and Livewire audio over IP.

Model LA-5174 StreamStacker-HD™ Decoder - Sixteen output, 1-RU decoder including AES and SDI (HD/SD) inputs and outputs and compensating video delay, plus VANC and RS-485 metadata outputs. Future upgrades will include DVB-ASI support, and Livewire audio over IP.

StreamStacker™AC-3 Distribution System- Enables multiple AC-3-format signals plus metadata to be carried via a single bit-accurate 16 to 20-bit/48 kHz AES pair. Comprises the following pair of complementary units:

Model LA-5421 StreamStacker™ Audio Bitstream Multiplexer - Multiplexes up to four AC-3 streams into a
single “Stacked” stream carried via one AES pair. Provides frame synchronization for each AC-3 input.

Model LA-5124 StreamStacker™ Audio Bitstream De-Mux/Splicer - De-multiplexes up to four “Stacked” AC-3 streams and allows for seamless AC-3 splicing. Dual redundant auto-ranging power supplies and hard bypass for mission critical applications. Serial and GPI/O controlled.

AutoNorm™- AutoNorm™ is an innovative approach to solving long-term loudness problems without sacrificing dynamic range or audio quality.
