UMIK-1 eller UMIK-2 målemikrofon kjøpes separat, og er nødvendig for å foreta automatisk Dirac-justering via HTx.

NYHET FRA MINIDSP! Multikanals (8) DSP med mulighet for Dirac (må kjøpes utenom direkte fra Dirac). Du kan tappe signal fra enten HDMI, RCA eller XLR (via TRS, husk at du eventuelt må kjøpe kabelsett for dette, se under foreslått tilbehør nederst på denne siden).

Informasjon fra produsent:

The Flex HTx is the bigger brother of the Flex HT, targeting the need for a multichannel processor with HDMI ARC/eARC capabilities and stellar analog and USB audio capabilities. Within a single rack unit, we packed all the possible connectivity we could fit.

Eight-channel audio input is via analog audio (RCA and TRS), eARC linear PCM over HDMI1, or USB Audio. Additional digital stereo input is supported over SPDIF and TOSLINK optical. Internally, we’ve provided a full suite of miniDSP’s flexible routing and audio processing features: bass management, parametric EQ, crossovers, advanced biquad programming and delay/gain adjustments. In addition, the miniDSP Flex HTx is software-upgradable with full-frequency Dirac Live®, the world’s premiere room correction system.

Continuing miniDSP’s focus on affordable high-performance audio, the Flex HTx features class-leading low noise and distortion figures. An OLED front panel display and volume control/encoder knob provides easy control.

The miniDSP Flex HTx is the perfect solution for a modern compact processor for home theater and multichannel sound.

REMINDER: Please note that the Flex HTx does not support bitstream (e.g. Dolby/DTS) decoding. The audio source must be able to output linear PCM (LPCM) for multichannel support over HDMI.

STOCK UPDATE(18/01/2024): All backlog has now shipped. Thanks for all your patience. All orders will now ship within 1-3days from order.

NOTE: The UMIK-1/2 are measurement microphones approved by Dirac Research. Knowing the major effect a wrong calibration/measurement would have on the final results of Dirac Live tuning, we strongly recommend that you select a UMIK-1/2 microphone together with your platform for a plug&play experience leading to best results. Any issues related to 3rd party microphones such as ASIO/USB audio driver incompatibility/Latency problems or incorrect calibration process will not be under our support structure by our support team.
