Audio Authority 2800 Series HD-IP: Digital Video via Ethernet

Introduction

Thank you for purchasing the 2800 Series HD-IP™ distribution system from Audio Authority®. The 2800 Series transmits HDMI® signals from one source over a dedicated Gigabit network via Cat 5e/6 cables, achieving distances far greater than possible with standard HDMI cables. Ultra high speed GbE (Gigabit Ethernet) preserves high quality 720p or 1080p video content. This manual covers one-to-one and one-to-many configurations.

HDMI Technology and the HD-IP Advantage

Standard HDMI devices transmit video and audio using TMDS (Transition Minimized Differential Signaling), designed for short cable runs. TMDS has limitations with longer cables, where high frequency signals can degrade, causing timing errors and blank screens due to differences in internal wire lengths.

HD-IP technology overcomes TMDS limitations using Ethernet standards, enabling reliable cable runs up to 250 feet and beyond, simplifying signal distribution, and ensuring robust signal integrity. Transmitting HDMI signals over IP networks redefines HDMI video distribution possibilities. Compliant with HDCP 2.0 specifications, this technology supports 128-bit AES encryption, overcoming traditional key verification limits for large systems while maintaining full HDCP compliance. Audio Authority's Gigabit infrastructure ensures picture quality virtually indistinguishable from the source, suitable for diverse applications.

Applications

The HD-IP system is designed for HDMI extension (point-to-point) or as a distribution system via a dedicated network (single source).

HDMI Extension

In point-to-point applications, the transmitter can connect directly to the receiver for distances up to 250 ft. (75m) using Cat 6 cable. Cat 5 cable can also be used, with range varying by quality. A GbE network switch can enhance range in a Cat 6 path.

Basic HDMI Extension Diagram:

A SOURCE device is connected via HDMI to the Model 2801 Transmitter (TX). A CAT 6 CABLE (up to 250 ft.) connects the transmitter to the Model 2811 Receiver (RX). The receiver is connected via HDMI to a TV. Power supply connections are not shown in this diagram.

Configuration Details: HDMI cables connect source and display equipment to the 2801 Transmitter and 2811 Receiver, respectively. A Cat 5 or 6 UTP cable connects the 2801 to the 2811. For best performance over longer distances, use properly terminated Cat 6 cables, adhering to EIA 568A or 568B standards. Always verify correct cable pairing with a network tester. Ensure DIP switches on the 2801 and 2811 are in the DOWN position.

Using the IR Pathway

IR signals can be passed from a 2811 Receiver back to the 2801 Transmitter to control the source equipment. Most 3rd party IR receivers are compatible when used with a connecting block. Environmental conditions like bright lighting or nearby electronics may affect IR receiver performance.

IR Connection Setup:

1. With power disconnected from the 2811 Receiver, connect your IR receiver and its power supply to a standard 12V IR connecting block. Connect a MONO 3.5mm cable from the emitter output of the connecting block to the 2811's 3.5mm IR port. The IR connection uses a 3.5mm jack where the Tip is the signal (+), and the Sleeve is for 12V.
2. With power disconnected from the 2801 Transmitter, connect a standard IR emitter to the 2801's IR 3.5mm IR port.

Note: The 2800 system may not be compatible with all IR equipment.

Distribution Network

In distribution applications, a single transmitter (or multiple) can connect to several receivers up to 250 ft. (75m) using Cat 6 cable. Cat 5 cable may also be used, with range varying by quality. A Gigabit Ethernet (GbE) switch is used to distribute video signals.

Single Transmitter Network

The 2800 system can distribute a single source signal to multiple displays on the same network using a standard Gigabit Ethernet switch (GbE). A managed switch is not required. The number of displays is limited by the available ports on the GbE switch.

Single Transmitter HDMI Network Diagram:

A SINGLE SOURCE is connected via HDMI to a 2801 Transmitter (TX). A CAT 5e/6 cable connects the TX to a GbE SWITCH. Multiple 2811 Receivers (RX) are connected via CAT 5e/6 cables to GbE SWITCH units, which then connect to TVs. Power supply connections are not shown in this diagram.

Configuration Details: HDMI cables connect source and display equipment to the 2801 Transmitter and 2811 Receivers. Cat 5e/6 cables connect the 2801 and 2811s to the GbE switch. GbE switches can be cascaded for larger systems or future expansion. Properly terminated Cat 6 cables are recommended for longer distances. All UTP cables should be terminated to EIA 568A or 568B standards. Verify correct pairing with a network cable tester. Ensure DIP switches on the 2801 and 2811s are in the DOWN position.

IR Pathway: IR signals can be passed from 2811 Receivers back to the 2801 Transmitter to control the source equipment. Compatibility with 3rd party IR receivers and potential interference from environmental factors are noted.

Troubleshooting

• Poor image quality: Use high quality 720p or 1080p content. Compressed video from some sources can cause poor quality. The 2800 Series requires no adjustment.
• Intermittent signal dropout: Ensure the 2800 Series is not on a network with other traffic, especially internet access. Verify all 2801 transmitters are set to a unique "channel". Keep AC wiring at least two feet away from 2800 Series network cables.
• No surround sound (multi-channel audio): The system does not support multi-channel digital audio. Adjust the source to output 2-channel PCM digital audio.
• No picture:
  • Check HDMI cable connections at input and output ports for looseness.
  • Ensure 2801 and 2811 units are connected to live AC outlets and check power indicators.
  • Use a network cable tester to confirm Cat 5e/6 cable termination and RJ-45 connector security. Check for cable defects.
  • Connect the display directly to the source using the HDMI cable from the 2801 end, then test with the 2811 connection cable. If an image appears, the display, source, and HDMI cables are likely not the issue.
  • If no picture persists, test with a short, known good HDMI cable and set the source resolution to 720p or 1080p. Reconnect the 2800 Series, ensuring the source resolution matches the test.

Considerations for Getting the Best Results

• Dedicated network: The 2800 Series is designed for a dedicated Gigabit Ethernet network, separate from general network traffic.
• Resolution tracking: Supports 720p and 1080p. For mixed displays, set the source to the lowest common resolution or use separate sources for different resolutions.
• Source resolution and video/sound quality: Source material quality significantly impacts output. Consider low-resolution or compressed video from some providers.
• Display devices: Perceived image quality depends on the quality of the TVs or projectors used.
• Distance: Long distances require premium Cat 6 cables. Use network switches to extend runs.
• Source and TV connection cables: Use short, high-quality HDMI cables with good strain relief.
• Interference: Nearby electrical devices (e.g., older monitors) can emit electromagnetic fields that affect signal quality.
