AVPro Edge 8x4 ConferX Auto Switching Matrix w/ HDBaseT Inputs and Outputs.  Microphone, Volume and Line Level Audio

Product Overview

The AVPro Edge AC-CX-84 ConferX 8x4 Auto Switching Matrix is a conference room AV switcher engineered specifically for multi-source, multi-display meeting environments. With eight HDBaseT inputs and four HDBaseT outputs, it handles video distribution over category cabling throughout a room or across a floor while integrating microphone input, volume control, and line-level audio in a single rack unit. Auto-switching detects active sources and selects them without manual intervention — a practical feature in conference rooms where presenters connect laptops, cameras, or wireless receivers interchangeably. The ConferX line is designed for corporate meeting room matrix switching with HDBaseT, addressing the full signal chain from the collaboration table to the display wall.

Product Description

The AC-CX-84 operates as the central hub of an 8-source, 4-display conference room system, receiving signals from up to eight HDBaseT transmitters — whether wall plates, table boxes, or wireless receivers — and distributing them to four independent HDBaseT output zones. Because all inputs and outputs are HDBaseT, the matrix eliminates the need for separate HDMI extender pairs; cabling runs are handled by single category cable connections to transmitters and receivers at each end point.

Audio integration goes beyond standard matrix switchers. The ConferX accepts microphone-level signals, manages volume control at the matrix level, and handles line-level audio — covering the audio signal chain for conference rooms that do not require a separate DSP or audio mixer for basic microphone and program audio management. This makes the AC-CX-84 appropriate for medium-sized meeting rooms, training centers, and huddle spaces where a separate audio DSP would increase cost and complexity.

Auto-switching logic monitors input activity and selects the highest-priority active source automatically, reducing the need for user interaction during meetings. Integrators can configure switching priority and behavior through the control interface, adapting the system to room-specific workflows. The unit is rack-mountable and designed for permanent installation in AV equipment racks.

Key Features

• 8x4 HDBaseT Matrix — Eight HDBaseT inputs and four HDBaseT outputs for all-category-cable AV distribution in conference environments.
• Auto-Switching — Automatically selects the active source based on priority logic, reducing presenter interaction and speeding up meeting starts.
• Microphone Input — Accepts microphone-level audio directly, eliminating the need for a separate mic preamp in standard conference room deployments.
• Volume Control — On-board volume management for de-embedded audio outputs, controllable via the web interface or control system commands.
• Line-Level Audio Integration — Handles line-level audio sources alongside microphone and program audio in a single unit.
• HDBaseT I/O Throughout — All inputs and outputs use HDBaseT, simplifying wiring by using a single category cable per endpoint rather than separate HDMI and extender components.
• Rack-Mountable Design — Standard rack form factor for installation in AV equipment rooms, closets, or under-table enclosures.
• Commercial AV Build Quality — Designed for continuous operation in commercial conference and collaboration environments.

Typical Applications

• Corporate conference rooms with eight presentation inputs (laptops, cameras, wireless receivers) routed to four display outputs
• Training centers and classrooms with multiple instructor and student input stations distributed to main and secondary screens
• Boardrooms requiring auto-switching between presenter inputs with integrated microphone and audio management
• Huddle spaces and collaboration rooms scaled to four display zones with shared category cable infrastructure
• Multi-room meeting suites where a single matrix serves up to four independent room displays from a shared source pool
• Government and legal conference facilities requiring reliable, zero-interaction source selection during proceedings

Frequently Asked Questions

What types of devices connect to the HDBaseT inputs?

Any HDBaseT transmitter compatible with the ConferX ecosystem can connect to the inputs — including AVPro Edge wall plate transmitters, table box transmitters, and wireless presentation receivers with HDBaseT outputs. The transmitters handle the HDMI-to-HDBaseT conversion at the source end so the matrix receives a single category cable per input.

How does auto-switching prioritize inputs?

The ConferX auto-switching logic detects active HPD (Hot Plug Detect) signals on the inputs. Integrators can configure the priority order through the control interface, so the most recently connected or highest-priority source takes the active output. This prevents the system from switching away from a presenter mid-meeting when another input becomes active.

Can the microphone input be routed independently from the video signal?

Yes. The microphone and line-level audio inputs are managed separately from the video routing, allowing audio to be sent to outputs independently of the source selected for video. This supports scenarios such as a room microphone that should be consistently routed to all displays regardless of which video source is active.

Is the AC-CX-84 compatible with third-party control systems?

Yes. The ConferX matrix supports RS-232 and LAN control for integration with Crestron, Control4, AMX, and other major control platforms. Contact AVPro Edge or Creation Networks for current driver availability.

What is the maximum cable run length for the HDBaseT outputs?

HDBaseT supports up to 100 meters on Cat6 or Cat6A for 1080p and up to 70 meters for 4K content depending on the paired receiver. Consult the compatible AVPro Edge HDBaseT receiver specifications for exact distance ratings at your target resolution.

Does this unit replace a separate audio DSP for a standard conference room?

For many standard conference room deployments, the AC-CX-84 can handle microphone input, volume control, and line-level audio routing without a separate DSP. For rooms requiring acoustic echo cancellation, complex mixing, or VoIP audio integration, a dedicated DSP would still be recommended alongside this matrix.
