AV Infrastructure Products
AV infrastructure products form the technical foundation for professional conference rooms and presentation systems: HDMI switchers and matrices, HDBaseT extenders (HDMI over CAT cable, up to 100 m), signal amplifiers, scalers and room control systems (Crestron, AMX). HDBaseT (specified by HDABT Alliance) transmits uncompressed 4K HDMI + Ethernet + RS232 + PoH (Power over HDBaseT) over a single Cat.6A cable – ideal for larger room installation distances. Crestron Home and AMX provide programmable room control (lighting, shading, AV, air conditioning) via touchpanel.

Frequently Asked Questions
▶ What is HDBaseT and why is it better than long HDMI cables? HDMI cables without amplifier have a maximum reach of 10–15 m (active up to 30 m). HDBaseT transmits 4K HDMI uncompressed over standard Cat.6A cable up to 100 m (HDBaseT 2.0: up to 70 m at 4K/60Hz). Advantages: cost-effective cabling, Ethernet + control signals + PoH in the same cable, professionally standardised (ANSI/SCTE 126). |
▶ What are AV matrices? An AV matrix (crosspoint switch) is a switcher that allows multiple input sources (e.g. 4 PCs, 2 laptops) to be switched to multiple outputs (e.g. 3 monitors, 2 projectors) in any combination. Each input can be routed to any output. Use: conference rooms with multiple presentation stations and displays, control rooms, broadcasting. |
▶ Is a room control system worthwhile for small conference rooms? For rooms with up to 2 AV sources and 1 display: simple HDMI switchers are sufficient. From 3+ sources and automatic control (blinds, projector, conference system at the touch of a button): room control systems (Crestron, AMX) are worthwhile – typically from 5,000–10,000 EUR installation cost. Simpler alternatives (Extron TouchLink, Crestron TSW) start below 3,000 EUR. |
