The Marmitek Connect TS21 is an optical (Toslink) digital audio switcher. You can connect two digital audio sources to its two Toslink inputs and route the selected source to a single Toslink digital output — with no signal delay or quality loss. It is designed for amplifiers that have too few digital audio inputs.

The unit supports the S/PDIF and Toslink standards and handles both uncompressed stereo LPCM and compressed multi-channel Dolby Digital and DTS signals. An improved 192 kHz sample rate ensures compatibility with high-resolution audio.

Key Features

• Switches two Toslink optical digital audio inputs to one Toslink optical digital output
• No signal delay or quality loss during switching
• Supports S/PDIF and Toslink standards
• Improved 192 kHz sample rate for high-resolution audio compatibility
• Supports uncompressed 2-channel LPCM audio signal
• Supports compressed 2-channel and multi-channel Dolby Digital and DTS audio signals

Product Benefits

• Adds two Toslink inputs to an amplifier that has only one, or none — without replacing any audio equipment
• Signal integrity is maintained at the output — switching produces no audible artefacts, delay, or degradation
• 192 kHz support means the switcher passes high-resolution audio formats without becoming a bottleneck in the signal chain
• Dolby Digital 5.1 and DTS 5.1 pass-through lets a single AV receiver handle surround-sound from two separate source devices
