Description
The HA5-Plus is an HDMI to 3G-SDI mini-converter designed to integrate HDMI sources into SDI monitoring and recording systems. It converts HDMI up to 1080p60 to 3G-SDI while preserving up to eight channels of embedded HDMI audio. The unit also supports progressive SD DSLR signals at 525p and 625p so DSLR cameras can be incorporated into SDI workflows.
Key features include EDID emulation, simple frame rate conversion from fractional to integer rates, and selectable embedded audio from HDMI or two-channel unbalanced analog RCA inputs. The HA5-Plus supports HDMI v1.4 and passes YCbCr 4:2:2, 4:4:4 or 4:2:0 color sampling with 8 or 10-bit depth where supported. An LED input indicator shows SD (green) or HD (red) status for quick signal identification.
Performance is engineered for stability with a 3G-SDI output that uses PLL clock filtering to reduce jitter and maintain image integrity. The equalized HDMI input supports cable runs up to 30 meters using 24 AWG HDMI cable, and the converter can embed two channels of analog audio into SDI while passing up to eight channels of HDMI embedded audio. Note that HDCP-protected content is not supported.
Connectivity includes one HDMI Type A input, one 3G-SDI output (Level A or B Dual Link), plus 1.5 Gb and 270 Mb SDI compatibility for legacy formats. Analog audio is provided via two RCA inputs and digital audio is passed as 24-bit 8-channel embedded streams. Configuration and firmware updates are available via the USB port using AJA MiniConfig on macOS or Windows.
The HA5-Plus suits a range of production environments including edit suites, on-set monitoring, and live events where HDMI sources must feed SDI infrastructures. It supports fractional-to-integer frame rate conversion to match project frame rates and preserves audio sync when embedding analog inputs. The compact footprint and locking power connector make it practical for behind-monitor mounting or on-camera rig use.
Installation is straightforward – connect HDMI and SDI cables, power the unit using the included universal power supply, and configure EDID or audio routing via AJA MiniConfig when necessary. The build includes a locking DC connector and optional P-TAP power cable support for battery use. A five-year warranty backs the product for professional deployments.
In summary, the HA5-Plus provides a compact, reliable bridge between HDMI sources and SDI infrastructures with DSLR progressive support, audio embedding options, and USB-configurable EDID and frame rate handling. Its feature set is optimized for producers, engineers, and technicians who need dependable HDMI-to-SDI conversion in mixed-signal workflows. The unit’s small size, universal power supply, and robust audio/video handling make it a practical tool for permanent and mobile installations.
