Extron's DMP 44 xi: A Versatile Digital Matrix Processor for Professional AV Applications
Extron's DMP 44 xi, the successor to the retiring DMP 44 LC, is now shipping and poised to revolutionise professional AV installations. This compact 4x4 audio mixer is designed to carry on the tradition of audio signal transparency and versatility, while offering a host of new features.
The DMP 44 xi is a 4x4 digital audio matrix processor, tailored for audio signal processing in commercial and high-end environments. It supports digital signal processing (DSP) for audio routing, mixing, and processing, offering flexible control over multiple input and output audio sources.
One of the standout features of the DMP 44 xi is the Extron DMP Expansion port. This port provides 14 output channels and 2 input channels for stereo input, exclusively for use with EXP compatible Extron devices. This expansion supports advanced speaker configurations such as 7.1.4 systems. The unit also supports audio sample rates up to 48 kHz at 24-bit depth per channel via the expansion port. Higher sample rate codecs like DTS 96/24 or Dolby TrueHD are resampled to 48 kHz for expansion bus transport.
The DMP 44 xi is packed with essential audio DSP tools for mixing, routing, and room optimization. It offers level controls, high pass filters, low pass filters, parametric EQ filters, and shelving filters (bass and treble). Additionally, it includes a compressor, limiter, and ducker.
Front panel controls include lockout modes, enabling administrators to restrict control access while permitting limited adjustments such as volume control. This feature is particularly useful in managed presentation settings. The DMP 44 xi also features RS-232 control connectivity, allowing configuration and control via Extron Product Configuration Software (PCS) or Simple Instruction Set (SIS) commands.
The DMP 44 xi is ideal for presentation applications that require line level audio matrix mixing with DSP in a small form factor. It is used in professional AV installations, supporting applications like boardrooms, classrooms, or auditoriums, where multi-channel audio processing and routing are necessary for high-quality presentations.
In summary, the Extron DMP 44 xi is a versatile and expandable digital audio matrix processor optimised for sophisticated audio signal management in presentation and professional AV environments. Its DSP processing, expansion ports for additional channels, and comprehensive control options via RS-232 and front panel interfaces make it a powerful tool for any professional AV installation.
