Masterclock's predecessor company - Clark and Associates - was founded by William (Bill) Clark in
1986 to build automation systems for the Radio & TV industries. Masterclock itself was
incorporated as an entity in 1994. Starting with a two person operation in the proverbial home
garage it has grown into a successful enterprise doing multi-million dollars in business throughout
the world.
The company's first product was the TCR100 time code reader card developed in 1986 to
synchronize IBM personal computers in Radio & TV broadcast networks automation systems. Over
the years Masterclock has introduced an array of products to meet the demand of customers
engaged in many different types of activities where correct and accurate time is critical; they are
among the world's most demanding and time sensitive users. These products now include digital
and analog clocks, time and frequency standards, devices to synchronize computers, networks and
many other systems where accurate time is required.
Open Standards
We adhere to open worldwide standards such as Network Time Protocol (NTP), PoE standard IEEE
802.3af, and IRIG / SMPTE / EBU time codes for the distribution of time and date information. Many
other companies use closed distribution standards thus locking the end user into proprietary
hardware and systems.
Made in USA
In order to maintain and control quality all of our products are engineered, designed and built in St
Charles (suburban St Louis), Missouri, USA.
Markets Served
Network / computer synchronization and time, power and utilities, Broadcasting and
communications, Government and Military, Commercial / Industrial Public Safety / 911 dispatch
centers

Product Value
Masterclock has established a reputation for reliability and good product value. All products are
carefully and conservatively designed for many years of use. Our products and systems are
modularized and "unbundled" allowing customers to buy just those parts or components that are
needed.
