Technolink TC-781 Eight Input Line Level Stereo Source Selector

In this review the Technolink TC-781 is judged as a simple, reliable way to add multiple analog sources to a stereo with only one free input. It is aimed at listeners with several line-level components or a new phono preamp who need a compact, passive selector rather than another powered switcher. The single biggest reason to buy is obvious: it adds eight stereo inputs without requiring power while keeping signal paths passive and shielded, so source switching remains straightforward and transparent.

Key Features

• Eight stereo inputs: Lets a user connect up to eight line-level source pairs and switch them into a single stereo input without rewiring.
• Vinyl stick-on labeling sheet: Supplied labels make it easy to identify and remember which inputs control specific components and reduce confusion when swapping sources.
• Gold-plated RCA connectors: All connectors are gold-plated to improve contact reliability and reduce corrosion over time for consistent signal transfer.
• Sturdy metal case: The metal enclosure shields internal circuits from interference and noise, keeping the passive switching quiet in most home setups.
• Passive, no power required: The selector requires no external power, eliminating hum from power supplies and simplifying placement.

Who It's For

The TC-781 suits people with multiple analog players - CD players, tape decks, streamers with analog outputs, and a phono preamp - who need a single, trustworthy device to manage those sources. Audiophiles who prefer a passive signal path and minimal electronics in the signal chain will appreciate the simplicity and noise-shielding metal case.

Those who need remote control, digital switching, or built-in amplification should look elsewhere; the TC-781 is a manual, passive selector without remote, tone controls, or powered buffering. It is best paired with quality components and a good grounding scheme to avoid hum with turntables.

Pros & Cons

Pros

• Provides eight stereo inputs in a compact footprint for flexible source management.
• Gold-plated RCA jacks and metal case deliver reliable connections and good shielding against interference.
• Passive design means no power supply noise and very simple installation.
• Included stick-on labels make setup and daily use more convenient.

Cons

• Passive switching offers no active buffering, so it will not amplify or restore signal level if that is needed.
• Manual front-panel switching lacks remote control or digital integration for modern smart systems.
