LAMBDA displays and reproduces up to 16 audio channels via AES or embedded HD-SDI input. It accepts industry-standard professional audio metadata via 9-pin serial input or by extracting it from the vertical ancillary (VANC) space of an applied HD-SDI input. Audio and metadata can be displayed and properly combined to allow for accurate monitoring. Any channel, channel pair, or Lt-Rt or Lo-Ro downmix can be monitored through the powerful two-way, digitally amplified speaker system, via a front-panel headphone connector, rear-panel, balanced analog stereo or AES-format digital output.

Loudness monitoring per the new ITU BS.1770 (RLB) standard also is included to give operators a built-in method for quickly verifying program loudness. Latency for PCM audio input is less than 1 mS; Dolby® Digital (AC-3) input 33 mS; Dolby® E (NTSC) 33 mS; Dolby® E (PAL) 40 mS. An optional tracking video delay compensates HD-SDI signal for these and additional delays.

Optionally, Dolby Digital (AC-3), Dolby E, and Linear Acoustic e2 (e-squared™) decoding can be internally performed on any of the discrete AES inputs or any of the embedded audio channels. All encoded metadata can be displayed and applied to the decoded audio and metering signals. Ethernet connectivity provides all metering information for remote monitoring and so-called “glass cockpit” applications (protocol available on request). The unit supports a second optional power supply for redundancy. A long-life and durable vacuum fluorescent display, plus two intuitive navigation clusters for menu and monitoring functions provide straightforward system navigation and audio adjustment.

Front panel controls and indicators comprise durable, reconfigurable vacuum fluorescent display that provides visual indication of audio levels, metadata and setup parameters. Two independent navigation clusters each with a rotary encoder and four switches control menus, monitor modes, volume, dim and mute.

Future options will include a built-in tracking delay applied to the input HD-SDI video signal prior to output to compensate for Dolby E and Dolby Digital delay of up to six video frames, plus a comprehensive Ethernet remote via the Telos Livewire™ and a remote Windows PC.
