Yes. The MX124 is an A/V processor and multichannel preamplifier, so it supplies processed line-level signals through its balanced XLR and unbalanced RCA outputs. Separate power amplifiers are required to drive the connected speakers. How many speakers and subwoofers can the MX124 support? The primary zone supports up to 17 processed audio channels in a 13.4 configuration, including 13 main speaker channels and four independent subwoofer channels. It can accommodate immersive layouts such as 7.4.6 and 9.4.4, with 11.4 balanced or 15.4 unbalanced multichannel output connectivity. Which room-correction systems are included? The MX124 includes Dirac Live Room Correction with Bass Control and the associated core licenses, allowing advanced optimization of speakers and as many as four subwoofers. Audyssey MultEQ XT32, Dynamic EQ, Dynamic Volume, and LFC are also included for an alternative guided calibration process. Do all HDMI inputs support 8K and high-frame-rate gaming? Yes. All seven HDMI inputs support 8K/60Hz and 4K/120Hz, so premium movie players and gaming systems are not limited to specific ports. VRR, ALLM, and QFT help support smooth, responsive high-frame-rate gaming. Which surround-sound and HDR formats are supported? The MX124 supports Dolby Atmos, DTS:X Pro, Sony 360 Reality Audio, MPEG-H Audio, and IMAX Enhanced. Its HDR compatibility includes static HDR, Dynamic HDR, HDR10+, HLG, and Dolby Vision, including low-latency Dolby Vision. Which music-streaming platforms work with the MX124? Supported platforms include Apple AirPlay, Qobuz Connect, Spotify Connect, TIDAL Connect, Bluetooth, and Roon. The processor supports high-resolution streaming at up to 32-bit/192kHz, while Roon Ready certification enables bit-perfect playback and compatible multiroom operation. Can the MX124 distribute entertainment to other rooms? Yes. Zone 2 provides independent HDMI audio/video and analog stereo audio, while Zone 3 provides independent analog stereo audio. This allows the MX124 to serve the main theater while supplying separate content to additional listening areas. Can the MX124 be installed in an equipment rack? Yes, but it does not use rack-mount ears. It occupies 5U and should be placed on a properly sized, weight-rated rack shelf with at least 6 inches of clearance above and 2 inches behind the rear panel for ventilation and cable access.
