LAMBDA(TM) Professional Digital Audio and Metadata Monitor
Designed to enable audio and metadata monitoring throughout the entire broadcast chain, the Linear Acoustic LAMBDA professional digital audio and metadata monitor displays and reproduces up to 16 audio channels from AES or embedded HD-SDI input. The system accepts audio metadata via 9-pin serial input or extracts it from the vertical ancillary (VANC) space of an applied HD-SDI input. Audio and metadata are displayed in combination to allow for accurate monitoring. Included loudness monitoring per ITU BS.1770 standard enables operators to verify program loudness quickly and accurately.

Any channel, channel pair, or downmix can be monitored through the powerful two-way, digitally amplified speaker system, a front-panel headphone connector, rear-panel balanced analog, or AES digital output. Optional Dolby(R) E/AC-3, decoding can be performed internally on any discrete AES input or any embedded audio channel. All encoded metadata can be displayed and applied to the decoded audio and metering signals. Future Ethernet connectivity will provide access to all metering information for remote monitoring and “glass cockpit” applications.

AERO.air (5.1)(TM) Transmission Loudness Manager
2008 TV Technology STAR Award Winner

The next-generation AERO.air 10-channel TV audio processor from Linear Acoustic (previously called the AEROMAX-5.1:XL) represents the world’s first TV audio processor to feature built-in Dolby(R) Digital (AC-3) encoding. Engineered on the foundation of the company’s supremely successful first-generation digital television processors, the AERO.air system enables broadcasters to deliver compelling 5.1-channel surround sound while saving them time, money, and space.

The comprehensive AERO.air solution is equipped with a loudness controller, upmixer, and metadata manager, as well as full-time, two-channel downmixing to support legacy analog paths. Built-in AutoMAX(TM) processing fixes two-channel audio that is broadcast wrongly signaled as 5.1 channels. Equipped with hard relay bypass and dual hot-swappable power supplies for mission-critical applications, the processor accepts 5.1 network audio, two-channel local audio and digital or analog auxiliary/EAS stereo audio for processing. HD-SDI audio and VANC metadata inputs and internal Dolby Digital (AC-3) encoding are available as options.

2008 Broadcast Engineering Pick Hit Winner and Chosen by NBC Olympics for the 2008 Beijing Olympic Games

Based on the award-winning upMAX 2251 product, the new UPMAX:neo shrinks the footprint to a compact, roadworthy 1RU chassis. It uses proprietary processing to create an infinitely adjustable, multichannel signal that is completely downmix compatible. Additional upmixing choices are added to the original upMAX algorithm for increased flexibility in post production applications. Metadata input is standard, along with GPI inputs to control upmixing.

Available options include an eight-channel, monitoring-grade balanced analog output with remote volume, mute, and return to reference inputs. Future options will include built-in metadata generation and HD-SDI I/O for embedding and de-embedding of audio channels and metadata.
