UPMAX V4-D OVERVIEW

Drawing upon the success of its predecessors in the UPMAX line, this compact, lightweight, and rugged unit produces stunning 5.1 channel audio from two-channel sources and is perfectly suited for OB trucks and post-production facilities.

Offering AES and auto-sensing HD/SD-SDI I/O, the UPMAX v4-D combines the renowned UPMAX® upmixing/downmixing algorithm with AutoMAX-II™ auto-detection for seamless transitions between stereo, three channel, and native surround input sources, producing an upmix that is completely downmix compatible.

The UPMAX v4-D comes standard with a built-in ITU loudness meter, dual power supplies, internal relay bypass, SNMP monitoring.

UPMAX V4-D FEATURES

  • 5.1-channel audio from 2- and 3-channel sources 

  • Fulltime 2-channel downmix output

  • Very low latency for live applications

  • HD/SD-SDI and AES inputs

  • HD/SD-SDI, AES outputs

  • Built-in ITU loudness meter

  • SNMP monitoring

  • Dual redundant internal PSU and relay bypass

UPMAX V4-D IN DEPTH

The Most Stable and Trusted Upmixing Available

Tracing its lineage back to the original UPMAX 2251, UPMAX v4-D offers the most stable and trusted algorithm in use today for both production and unattended upmixing. Critically, its output is completely downmix compatible and the resulting downmix is nearly indistinguishable from the original 2-channel source. For unattended operation, AutoMAX-II detection seamlessly and automatically transitions between discrete and upmixed audio, or control can be handled via GPI/O.

 

Flexible Surroundfield

The upmixed “surroundfield” can be infinitely adjusted, allowing programming ranging from simple stereo audio to an LtRt downmix to be appropriately reproduced through a 5.1-channel playback system. Optional bass enhancement for the LFE channel allows a subwoofer channel to be created without compromising the downmix.

 

Built-in Loudness Metering

A built-in LKFS meter provides loudness measurements per ITU-R BS.1770-3, simplifying the process of making sure output levels are properly adjusted to comply with loudness regulations around the world.
