DA12 Signal Distribution Amplifier
The DA12 is a dual-channel distribution amplifier for time code signals (IRIG-B, SMPTE, EBU).
A single time code input is amplified and distributed to twelve buffered outputs, so one central source can feed multiple displays and devices without the signal loss and reflections you get from T-taps. Standard 1U rack mount, AC power.

Frequently asked questions
How many outputs does the DA12 have?
Twelve. A rear selector chooses between one input driving all twelve outputs, or two inputs each driving their own bank of six.
What is the advantage of a DA12 over T-taps?
Every output is separately buffered and amplified, so each receiver gets a full-strength signal. T-taps split one signal and cause impedance mismatch, reflections and level loss, which gets worse with every receiver you add. For more than two or three receivers a distribution amplifier is the reliable answer. The two banks of six can be linked or kept separate with the rear selector.
Which impedance does the DA12 use?
The input and outputs are 50 Ω on BNC. A 75 Ω coaxial feed connects without difficulty, which is how the unit is normally used in a broadcast installation; for the cleanest signal Masterclock recommends terminating with 50 Ω. Send us your source type and signal level and we will confirm the gain setting for your installation.
What is the lead time for this product?
Standard lead time is 8-10 weeks from Masterclock USA. Daylight bv stocks the most common references in Ghent. Contact us for current availability and any rush options.
