Home Theater Onscreen Guide

Connect the H16-AES HDMI output (labeled eARC) to your display.

By default, the H16-AES is set to Pure mode (audio is decoded and pass through to AoIP with no DSP processing). Switching to other modes applies sound processing effects, which can alter the audio quality of the AES channels.

Go to Speaker setup.

Select Speaker layout

Choose the speaker layout that matches your HDMI source.

Return to the Setup menu and select Auto Room Test with the microphone connected to the H16-AES. Place the microphone at your primary listening position. For the best Dolby Atmos experience, ensure your main listening spot is centered between the front left and front right speakers, ideally near the center of the room. For detailed guidance, refer to the Dolby setup guide online.

Perform manual adjustment to fine tune the speakers parameter after the auto room test.

Connecting To Nuprime-X 8 Channels Device’s AES Inputs

You don’t need to understand how AES works if your goal is simply to connect the H16-AES to the NuPrime-X MCX-800AD or Fusion 8D in a full home theater setup. Just use a DB25 male-to-male cable as shown below.

Connecting to Device with Two Channels AES Inputs

The 16 AES3 channels are output via two DB25 connectors following the Tascam pinout format, which is a standardized wiring scheme commonly used for multichannel digital or analog audio transmission.

AES59

AES59 defines the pin-out and wiring standard for AES3 digital audio signals when transmitted over DB25 (D-sub) connectors. It ensures that multi-channel AES3 connections (typically 8 channels in and 8 channels out) are interoperable between different manufacturers’ equipment — such as audio interfaces, consoles, and recorders.

  • Connector type: DB25 (25-pin D-sub)
  • Standardized mapping: Matches the TASCAM analog DB25 pinout, but carries digital AES3 signals instead of analog audio.
  • Purpose: Provides a consistent way to connect multiple AES3 channels through a single cable.

AES - Each DB25 port carries 8 channels (4 stereo pairs), so two DB25 connectors provide up to 16 channels of AES3 digital audio

H16_AOIP_v2_05_0648_20250930.upg

  • This firmware reduces the following 3 problems:
    • Incorrect LFE level
    • Intermittent problems - ticking noise, playback stops/restarts after repeat fast forward or rewind
    • These problems have been reduced but not completely fixed.  We are expecting another firmware update in November, 2025.
  • H16-AIP - update not necessary as the improvement is only partial, wait for next firmware update.
  • H16-AES shipped with firmware prior to v2_05_648. No update is needed.

Next Firmware Update: Estimated near end of November, 2025.  Bug fixes and DSP/EQ features.

If you update H16-AIP with this firmware, your channel outputs will follow this sequence:
