DLA44 - 8 channel (5.1/2.0) digital audio upmixer and loudness control unit with Quad Speed audio bus (based on Linear Acoustic algorithms)
Description
Inconsistent DTV audio loudness, or the so-called “loud commercial problem” is the number one complaint of television viewers and it is driving them away. It is clear that with the transition to digital (HD), a simple and cost effective solution is needed right now!
The DLA44 is based on third generation audio and loudness management technology by Linear Acoustic. The DLA44 protects your viewers from loudness shifts and loss of surround sound in a simple, cost effective, modular and hot-swap manner next to over 150 other Synapse modules.
The DLA44 accepts three pairs of PCM audio to handle a program stream containing 5.1 and two channel audio. The unit can apply multiband, multistage loudness control and upmixing to the applied audio. Loudness control is provided by the popular AEROMAX algorithm, while upmixing is provided by the air-proven and industry standard UPMAX algorithm. Both technologies are used world-wide to provide consistent and compelling 5.1 channel audio while remaining completely downmix compatible.
The DLA44 also includes the new AutoMAX-II auto-detection algorithm to smoothly and automatically bypass upmixing when applied content is 5.1 channels. The AutoMAX-II algorithm prevents any loss of dialogue or cause any switching artifacts. Upmixing and loudness processing modes can also be controlled by the ACP protocol and Cortex or by GPI contact closures.
A full-time downmixed version of the main program is provided as the fourth AES output pair. This signal can be either a stereo LoRo downmix or an industry standard LtRt surround encoded mix compatible with all legacy consumer decoders.
