The MUX-2A-QAM 2 x ASI to QAM Multiplexer from Blonder Tongue will aggregate two ASI sources into one QAM output channel for delivery over a standard coaxial distribution network. It features a single QAM RF output in the 54 to 864 MHz range, and provides the capability to filter program streams and to assign major/minor or a single 4-digit channel number to each.

The MUX-2A-QAM also provides Emergency Alert System (EAS) program switching through a third ASI input and terminal block contacts. The EAS input source can be shared among multiple MUX-2A-QAM units by looping it from one to another unit without the need for external splitting and amplification.

Supports MPEG-2 transport stream tables: PAT, PMT, MGT, RRT, STT, and VCT
Re-maps duplicate PIDs, program numbers, and minor channel numbers
Allows sharing of the EAS input source among multiple units
User-defined major/minor or 4-digit CATV virtual channels
User-defined channel names
EAS input replaces up to 12 program streams
Supports PID filtering and PSIP re-assignment
Provides QAM 256 Output at 38.8 Mbps
Accepts ASI input as EAS input source
User-defined QAM Output Parameters
Maintains MPEG-2 mapping
