CLKTCD12 Analog Digital Timecode Clock SMPTE IRIG-B
The CLKTCD12 was a timecode-driven clock (IRIG-B, SMPTE, EBU) in a 12-inch format.
LEGACY
Still supported for software and repairs.
This model is no longer in production. We recommend as modern alternative:
View the alternative: CLDTCD12 →This model has been retired. For new timecode installations of a similar size, Daylight bv recommends the current TCDS range (TCDS24, TCDS26 or TCDS44) as a direct replacement, depending on your exact viewing distance and digit-size requirements.

Frequently asked questions
Is the CLKTCD12 still available?
No, retired. For timecode-driven clocks in a similar size, refer to the TCDS range: TCDS24 (5.8 cm) or TCDS44 (10.2 cm) depending on your viewing distance.
What is a good replacement?
For a one-to-one replacement in an existing installation, consult Daylight bv to determine the right TCDS variant based on colour, viewing distance and case-shape requirements.
What if the CLKTCD12 still works?
A working unit can stay in service. In case of failure: contact Daylight bv for diagnosis and replacement advice.
Why order from Daylight bv rather than directly from Masterclock?
Daylight bv has been the authorised Masterclock distributor since 2014. You get invoicing in EUR with Belgian VAT, local support in Dutch, French or English, on-site service by prior arrangement and no complications with customs or US imports.
