tvONE 1T-DA-564 – 1x4 DVI Distribution Amplifier with Audio

Product Overview

The tvONE 1T-DA-564 is a 1-input, 4-output DVI-D distribution amplifier that delivers a single DVI source to four simultaneous outputs with high-bandwidth signal amplification and equalization. Compliant with HDMI v1.3 specifications, it supports Deep Color (10-bit and 12-bit), Dolby TrueHD, Dolby Digital+, and DTS-HD Master Audio. A distinguishing feature of the 1T-DA-564 compared to simpler DVI DAs is its four analog stereo audio outputs and four S/PDIF coaxial digital audio outputs, enabling independent audio routing to each display location. EDID management ensures source compatibility with connected displays across all four outputs.

Product Description

The 1T-DA-564 is the audio-equipped model in tvONE's DVI DA series, designed for installations where audio must be distributed alongside the video signal to each display location. It handles DVI-D digital input and distributes it to four DVI-D outputs at up to 225 MHz bandwidth (2.25 Gbps), with built-in signal amplification and equalization to maintain signal integrity over long cable runs. HDMI v1.3 compliance means the unit processes Deep Color at 10-bit and 12-bit bit depths, and supports the newer lossless audio formats including Dolby TrueHD, Dolby Digital+, and DTS-HD Master Audio. At each output, a corresponding pair of analog stereo audio outputs and S/PDIF coaxial digital audio outputs are provided, so audio can be broken out and routed to speakers or amplifiers at each display location independently. An HDMI source can be connected using a standard HDMI-to-DVI cable adapter, making the unit compatible with modern HDMI source equipment. Front panel EDID switching selects the EDID reference from a connected priority display or from an internal resolution lookup table — avoiding source/display incompatibility across the four outputs. Multiple 1T-DA-564 units can be cascaded for larger distribution architectures. An optional 19-inch rack mounting kit accommodates single or dual unit rack installation.
