MINIDSP FLEX HTx 

Audio DSP Processor 2x8 Channels SHARC ADSP21489 HDMI ARC eARC

MINIDSP FLEX HTx Audio DSP Processor 2x8 Channels SHARC ADSP21489 HDMI ARC eARC

Big brother of the Flex HT, the Flex HTx from MiniDSP is a 2x8-channel multichannel audio processor perfect for integration into a home theater or multichannel sound system. It features 16 analog inputs, 8 on RCA connectors and 8 on balanced 6.35mm jacks. There are also numerous digital inputs, including USB-B, Toslink optical, SPDIF coaxial and HDMI ARC/eARC. It features a full suite of audio processing functions such as bass management, parametric equalizers, crossover adjustment, advanced biquad programming and delay/gain settings.

In terms of performance, the MiniDSP FLEX HTx achieves a very low level of noise and distortion, making it a device of choice. HDMI ARC/eARC and USB inputs support 8 channels of linear PCM. A front-panel OLED display and volume control knob provide easy control of the device. Settings can be easily modified using Stereo Dirac Live® acoustic correction software (DIRAC license not included, but available here).

Output is via 8 channels on RCA connectors or 8 channels on balanced 6.35mm jacks, with THD+N of just 0.00014% and 0.0001% respectively.

Please note that Flex HTx does not support bitstream decoding (e.g. Dolby/DTS). The audio source must be capable of producing linear PCM (LPCM) for multichannel support via HDMI.

Note :
 5/5
Date :
Remplace avantageusement les 2 DCX 24-96 pour gérer les 3 voies de mon système
Après avoir mis au point mon filtrage à l'aide de petit Behringer DCX, j'ai choisis de bénéficier du rapport signal/ bruit exceptionnel de ce DSP : 24dB de mieux (encore amélioré sans doute par le recours à un filtre à Supercondensateurs)
Les seuls bémols :
* Seulement 4 presets
* Pas de gestion de la convolution FIR contrairement à d'autres appareils de ce gamme moins ambitieux
