ACT1000

ATSC to QAM Transcoder

The Drake ACT1000 is designed to transcode one 8VSB/ATSC broadcast channel to a single
QAM output channel. It may also be used to translate or process a single QAM channel on
its original input channel assignment or to a different QAM output channel. Simplicity and
affordability are the end result of this new product from Drake that is in a card form factor
and integrates into Drake’s popular RMT150 chassis and is powered and controlled by the
PS151 power supply allowing up to 10 ACT1000’s to fit into 2 rack spaces (3.5”).

Drake’s ACT1000 is the logical choice for transcoding ATSC broadcast channels to QAM for
distribution on any RF cable type system where sufficient bandwidth is available and the
added cost of multiplexing two ATSC channels to one QAM channel is prohibitive.
Additionally, Drake’s ACT1000 system is the densest configuration currently available with
the ability to house 10 transcoders in 2 rack spaces.

Customers using Drake’s popular SCTx860 series satellite to QAM transcoders may mix and
match satellite and ATSC transcoders in the same chassis for maximum flexibility and cost
savings.
