Features
Diplex, input and output modules, return path module
The AC1500 amplifier is delivered according to the specifications defined in the
ordering code.
Optional return path operation needs plug-in diplex filters
(Figure 4, positions 4 and 10). The available diplex filter types are CXF065
(65/85 MHz), CXF085 (85/105 MHz) and CXF204 (204/258 MHz). It is also
possible to order the amplifier without diplex filters.
Input and output modules are passive plug-ins used to control the outputs – see
tables 1, 2 and 3. During amplifier adjustment the plug-in unit positions for input
and output modules must be equipped at least with the 0 dB modules.

AC6110 0 dB input module, no bypass 0 dB not used
AC6124 Two-way splitter, bypass in use -4 dB -7 dB *)
AC6113 2/12 dB tap, bypass in use -12 dB -5 dB *)
AC6115 1/16 dB tap, bypass in use -16 dB -4 dB *)

Output module 2 usage is similar to Output module 1.
Installed output module 2 controls how amplifier bypass / output 3 port is
configured. When output module 2 slot is equipped with AC6120 module, this
port is input bypass port. When output module 2 slot is equipped with a tap or
splitter module, this port is output 3 port.
AC1500 has return amplifier built in on the motherboard. For upgrading return
path there is no need to change return amplifier, but only diplex filters and the
