Kramer KIT-400 4K Auto-Switcher / Scaler Kit over Long Reach HDBaseT
Product Overview
The Kramer KIT-400 is a 4K auto-switcher/scaler kit for HDMI and VGA over long-reach HDBaseT, consisting of the KIT-400T transmitter/switcher and KIT-400R receiver/scaler for conference rooms and presentation spaces where a single-cable HDBaseT connection links the presenter table to the display. The transmitter accepts two local HDMI inputs, one local VGA input, and a remote HDMI input via the HDBaseT link, providing four total source connections with priority or last-connected auto-switching and Maestro room automation for automatic display power control. The receiver scales the selected signal to match the display's native resolution, up-scaling or down-scaling as required for reliable 4K and HD output. Power over Cable (PoC) allows only one unit to be externally powered — the other is powered through the HDBaseT cable, simplifying installation at the display end.
Product Description
The KIT-400T transmitter provides three local input connections — two HDMI and one VGA with dedicated 3.5mm audio jack — plus an additional remote HDMI input on the KIT-400R receiver, giving presenters four total source options controlled via dedicated front panel selector buttons per input or automated last-connected/priority switching. Maestro room automation powers the display on when a source is detected and off after a configurable idle period, eliminating manual display operation. The KIT-400R receiver includes a scaler that up- or down-scales the received signal to match the connected display's resolution, outputting up to 4K@60Hz (4:4:4) HDMI. Audio de-embedding on the receiver provides balanced stereo output for room audio systems, while an unbalanced stereo output is available on the transmitter side. Bidirectional RS-232 extension over the HDBaseT link allows serial device control between the transmitter and receiver ends. I-EDIDPro EDID processing on both units handles EDID communication between sources and the display reliably across the cable run. The HDBaseT connection extends up to 40m at 4K@60Hz (4:2:0) and further for lower HD resolutions, with PoC ensuring the display-end receiver needs no local power supply when the transmitter is powered.
Key Features
- 4-Input Auto-Switching — 2 local HDMI + 1 local VGA on the transmitter, plus 1 HDMI on the receiver; priority, last-connected, or manual switching.
- Maestro Room Automation — Auto powers display on/off based on source connection; configurable idle timeout.
- 4K Scaler at Receiver — KIT-400R up/down scales the received signal to the display's native resolution, up to 4K@60Hz (4:4:4).
- Long-Reach HDBaseT — Up to 40m at 4K@60Hz (4:2:0); further reach at 1080p60.
- Power over Cable (PoC) — Power only the transmitter or receiver; the other unit receives power through the HDBaseT cable.
- Audio De-Embedding — Balanced stereo audio output at the receiver for room audio systems.
- Bidirectional RS-232 Extension — Serial control of remote devices at either end of the HDBaseT link.
- HDCP 1.4 / 2.2 Compliant — Handles protected 4K content from premium HDMI sources.
- I-EDIDPro EDID Processing — Intelligent EDID management on both transmitter and receiver.

Frequently Asked Questions
Does the KIT-400 include both transmitter and receiver?
Yes. The KIT-400 is a complete kit including the KIT-400T transmitter/switcher and the KIT-400R receiver/scaler. Both units are required for a complete installation.
What cable type is required for the HDBaseT link?
The KIT-400 supports CAT6 or CAT7 solid-core UTP cable for the HDBaseT link, with a maximum run of 40m at 4K@60Hz (4:2:0) or up to 70m at 1080p60.
Does PoC mean only one power supply is needed?
Yes. With PoC enabled, you only need to power one unit (either transmitter or receiver). The other unit receives its power over the HDBaseT Cat cable, eliminating the need for a local power outlet at the display mounting location.
Can the KIT-400 be controlled by a room control system?
Yes. Ethernet and RS-232 control via Kramer Protocol 3000 allow integration with Kramer Control, Crestron, AMX, and third-party control systems for input selection, volume, and Maestro automation configuration.
