More about AV Tuners

Often times it can be useful to have a tuner in your AV installation. Not all displays can tune TV channels; video projectors and monitors do not have built-in TV tuners to receive off-air or cable TV signals. Tuners can also be used to monitor live camera feeds or over the air broadcasts. Presentation room switchers often need a dedicated tuner that can be routed to displays on demand. Contemporary Research has established a reputation for bringing superior tuner technology to the AV market.
