4 Input 4K HDMI + Analog Audio over HDBaseT Card (F 32)

The Kramer DTAxr-IN4-F32 is a four-channel twisted-pair receiver card designed for VS-3232 Series Modular Multi-Format Digital Matrix Switchers. It brings four extended-reach HDBaseT signals from the line into the chassis, combining 4K60 4:2:0 HDMI video with selectable embedded or de-embedded analog audio. The same card also transports bidirectional RS-232, Ethernet, and IR, giving the matrix access to multiple signal and control functions through one integrated input-card design.

Ideal Use Cases

This model is intended for systems built around a VS-3232 Series modular matrix switcher. It is particularly relevant when the chassis must receive four HDBaseT feeds while preserving video, analog audio, network, and control capabilities. Its four-channel configuration can support matrix designs that need several extended-reach inputs without separating video reception from the associated control and communication signals.

• Expanding a compatible VS-3232 chassis with four HDBaseT input channels.
• Receiving 4K60 4:2:0 HDMI signals over extended-reach twisted-pair connections.
• Integrating selectable embedded or de-embedded analog audio with matrix inputs.
• Carrying RS-232, Ethernet, and IR alongside the incoming HDMI signals.

Why Choose This Model

The DTAxr-IN4-F32 consolidates several signal types into one receiver card. Each installation gains four incoming HDBaseT channels rather than a single-channel interface, while the card’s selectable audio handling accommodates systems that need either embedded audio or de-embedded analog audio. Bidirectional RS-232 further supports communication between the line and chassis, while Ethernet and IR transport keep network and infrared functions associated with the same input architecture.

This combination is useful when the matrix must do more than accept video. Instead of treating HDMI, analog audio, serial control, Ethernet, and IR as unrelated functions, the card receives them through a unified HDBaseT-based design developed for the VS-3232 platform.

Installation and Integration

The DTAxr-IN4-F32 is an input card for the VS-3232 Series Modular Multi-Format Digital Matrix Switchers. It operates as the chassis-side receiver for four extended-reach HDBaseT lines. During system planning, the card should be matched with the compatible matrix chassis and the required line-side HDBaseT equipment. The source information does not specify that a chassis, transmitter, cable, or accessory is included with this SKU.

Integration should account for every transported function required on each line. The incoming signal design can include 4K60 4:2:0 HDMI, selectable embedded or de-embedded analog audio, RS-232, Ethernet, and IR. The RS-232 path is bidirectional, allowing serial communication in both directions. All received functions are passed from the line into the matrix chassis, providing a clearly defined role within the modular signal chain.

Performance Highlights

The card supports 4K video at a 60 Hz refresh rate using 4:2:0 chroma sampling. Its stated bandwidth is 10.2 Gbps. Four channels are available on a single card, enabling the compatible matrix to receive four extended-reach HDBaseT signals at once. These published capabilities define the model’s video performance without relying on unspecified HDMI-version, HDCP, HDR, or distance claims.

Audio flexibility is another central capability. Analog audio can be selected in embedded or de-embedded form, allowing the input configuration to reflect the audio path required by the connected system. RS-232, Ethernet, and IR support add control and communication transport to the core video and audio functions.

What Makes It Different

The distinguishing feature of the DTAxr-IN4-F32 is the breadth of functions provided across a four-channel receiver card. It is not described only as a 4K HDMI input card: it also incorporates analog audio selection and HDBaseT transport for serial control, Ethernet, and IR. That combination gives each compatible VS-3232 installation a coordinated way to move incoming media and supporting signals from the HDBaseT line to the chassis.

Its extended-reach HDBaseT role also separates it from a direct local HDMI input design. The card is purpose-built to terminate four twisted-pair HDBaseT feeds inside the modular matrix environment while retaining the associated audio and control capabilities identified for the product.

Final Assessment

The Kramer DTAxr-IN4-F32 is a specialized expansion choice for a VS-3232 Series matrix that requires four extended-reach HDBaseT inputs. It combines 4K60 4:2:0 HDMI performance at 10.2 Gbps with selectable embedded or de-embedded analog audio, bidirectional RS-232, Ethernet, and IR. For a compatible modular matrix system, its value lies in bringing those functions together on one four-channel receiver card with a defined line-to-chassis signal path.
