The Marmitek Connect DA21 is a digital-to-analogue audio converter that accepts either an optical Toslink or a coaxial RCA digital input and outputs a stereo left/right analogue signal. It is designed for setups where an amplifier or audio system has too few — or no — digital audio inputs.

The unit uses a Wolfson DAC and supports an improved 192 kHz sample rate for high-fidelity sound reproduction. A front-panel switch selects between the Coaxial and Optical digital inputs.

Key Features

• Converts optical (Toslink) or coaxial (RCA) digital audio input to stereo L/R analogue output
• Wolfson DAC (Digital-to-Analogue Converter) for accurate sound reproduction
• Improved 192 kHz sample rate for high-quality audio output
• Front-panel selector switch to choose between Coaxial and Optical input
• Supports uncompressed digital stereo signals (2CH LPCM)
• Supports 16-bit or 24-bit depth; sample frequencies: 8, 32, 44.1, 48, 96, 176.4, and 192 kHz

Product Benefits

• Adds a stereo analogue output to any digital audio source, solving the common problem of amplifiers with no free digital input
• The Wolfson DAC delivers clean analogue conversion without the artefacts associated with lower-quality DAC chips
• 192 kHz support ensures the converter is compatible with high-resolution audio sources, not just standard CD-quality signals
• A single front-panel switch makes input selection immediate — no menus or remote control required
