384 kHz/32-bit Hi-Grade DAC
No matter what you're listening to, it will sound powerfully full, clean and clear. A premium-quality AK4458 digital-to-analog converter from Asahi Kasei implements unique low-distortion filtering technologies for clear sound, and unlocks the full potential of any audio format, including compressed, lossless, and hi-res audio (MP3, WMA, FLAC, WAV, AAC, Apple Lossless, AIFF, DSD 11.2 MHz, and Dolby TrueHD).
AccuEQ Advance conducts two measurements- one to set the level, the other to set the distance and crossover for ALL speakers, including the subwoofer. In the second round of measurements, your room’s sonic characteristics are evaluated. Using this information, AccuEQ is able to prevent standing waves from forming by adjusting frequency response. The technology also detects and compensates for background noise, such as the hum from an HVAC, to ensure accurate equalization.
Choose to include or bypass EQ measurement for front left and right speakers, and choose to automatically or manually set the EQ. Further, you can save your own manual EQ settings into three available presets.
The new AccuReflex technology aligns the phase of upfiring "height" speakers with the sound coming directly from your
other speakers. Any delay is resolved so that everything arrives at your ears at the same time. The result is cohesive
reproduction of object-based soundtracks.
Perfect for Custom Installation
Integra products are designed and engineered to meet the demands of custom audio/video systems installers. Besides Recall with Lock / Unlock and PC Software Support, the DRX-4.3 includes system integration connectivity such as RS232 and IP control with support for 2-way communication with 3rd party home automation systems. A pair of infrared (IR) inputs and an IR output make for a clean, reliable installation and allow pass-through of IR signals to control other devices connected to the DRX-4.3, such as a TV or Blu-ray player. Three fully programmable 12 volt triggers can be used to raise/lower a projection screen, power on/off an external amplifier and open/close the drapes all with the touch of a button. Optional rack mount kits for all full size models provide a clean, finished look when installed in racks and cabinets, especially with the unit's aluminum faceplate. Integra works closely with control systems partners such as Savant, Crestron, URC, RTI, and Ihiji and supports Control4 Simple Device Discovery Protocol (SDDP) and AMX Device Discovery for simplified system integration.
