ViewHD SPDIF/TOSLINK Optical Digital Audio 4x4 True Matrix - Flexible

In this review of the ViewHD SPDIF/TOSLINK Optical Digital Audio 4x4 True Matrix, the bottom line is simple: it is the most flexible optical audio routing box available for small studios, home theaters, and AV integrators who need reliable, lossless switching. The unit is aimed at users who require any-input-to-any-output routing without signal degradation, and the single biggest reason to buy is its active IC switching that preserves audio fidelity while allowing four inputs to be sent to any combination of four outputs. Setup is straightforward and the included remote and universal 5V adapter make it ready for most installations.

Key Features

• True 4x4 matrix: Sends any of four optical/SPDIF inputs to any of the four outputs independently for complex routing in multi-room setups.
• Active IC switching: Uses electronic switching rather than mechanical relays to ensure consistent, lossless signal transfer and minimal wear over time.
• Enterprise grade construction: Full metal jacket housing provides durability and rack-ready feel for professional use.
• Remote control included: The supplied remote and user manual let users change routing without accessing the rack or behind-the-TV area.
• Supports long runs: Rated for output reach up to 30M and data rates up to 16Mbps, making it suitable for typical optical audio cabling distances.

Who It's For

The ViewHD 4x4 matrix is best for AV enthusiasts, small recording/project studios, and integrators who need flexible optical audio distribution without degrading multichannel content such as 5.1. It is a good fit where several sources must be shared to multiple rooms or devices, and where dependable, electronic switching is preferred over manual patching.

Users who only need a simple one-to-one converter, or those relying exclusively on analog or HDMI audio, should look elsewhere, since this unit is specialized for optical/SPDIF/TOSLINK digital distribution and lacks analog or HDMI breakout features.

Pros & Cons

Pros

• Reliable electronic switching that maintains sound quality and supports multichannel audio without distortion.
• Flexible routing allows any input to be sent to any combination of outputs for complex setups.
• Solid metal construction and included power adapter add to perceived long-term value and durability.

Cons

• Limited to optical/SPDIF/TOSLINK formats, so it is not a complete audio hub for systems needing analog or HDMI switching.
• No built-in display for routing status, requiring reliance on the remote or front panel indicators during setup.
