Blonder Tongue QTM-HD-4 QAM Transcoder Module - High Definition...

An integrated satellite selector switch allows operator to select any of the QPSK/8PSK inputs from up to 4 different satellites without the need for a separate external multiswitch. The 4 RF QAM output channels can be grouped in any 42 MHz-wide span, for example grouped consecutively in a 24 MHz-wide span, or grouped as two pairs of adjoining RF channels each 12 MHz wide, or any other possible combination of 4x 6 MHz-wide channels placed in a 42 MHz-wide span.
The QTM-HD-4-NPU functions the same as the QTM-HD-4, but with a “Null Packet” feature that allows adding/removing null packets to/from the input stream.
The QTM-HD-4/NPU may be monitored and controlled via GUI-based web pages from any computer either locally or via the internet.
