How to Use the Grundig CD 301 Link

1. Locate the "LINK" 5-pin DIN socket on the back panel.
2. Use a 5-pin DIN to 5-pin DIN cable to connect to a compatible Grundig amplifier (e.g., Grundig A-9000, V-9000, R-35).
3. Once linked, the amplifier’s remote control can operate the CD player.
4. Without a Grundig amp, the Link port is unused — the player works fully via front panel buttons.

2. The Optical "Link" (Toslink Connection)

The Grundig CD 301 was technically advanced for its era, featuring a digital optical output (Toslink). In the 1980s, this was the "link" to the future—a way to bypass the player's internal DAC and send raw digital data to an external, higher-quality converter.

How to use the CD 301’s optical link:

• The Problem: The optical output is a square Toslink port (JIS F05). Modern DACs use 3.5mm mini-Toslink or round RCA-ish Toslink.
• The Solution: You need a "Toslink to Toslink" cable with square ends. Alternatively, you can buy a "Toslink to Mini-Toslink" adapter.
• Why use it? The internal TDA1541 DAC is lovely, but upgrading to a modern external DAC (like a Schiit Modi or Topping E30) via the optical link can dramatically lower the noise floor and tighten the bass response of this vintage unit.
