MZC-88 Installation Instructions Page 17
HED-1.0 MASTHEAD AMPLIFIER
The HED-1.0 Masthead Amplifier provides remote connection for the AM and FM antennas used with the MZC-88. The HED-
1.0 can be located up to 100’ away from the MZC and other system components, reducing RF interference therby improving
reception and reducing noise. Lenghts longer than 100’ can be used, but expect reduction in tuner sensitivity in proportion
to cable length.

HED-1.0 Masthead Amplifier
1. FM/AM — One, F-type terminal connects to the FM/AM/75Ω terminal on a MZC-88 Rear Panel via RG6 coaxial cable.
FM and AM broadcast reception is output from this terminal and fed to the appropriate tuner section (AM or FM) inside
the MZC-88. Tuner 1 and Tuner 2 are both fed from this connection.
NOTE: The HED-1.0 is phantom powered via this terminal from the MZC, so the run of RG6 must be an unbroken run
with no splits or RF amplifiers.
2. FLANGE SCREW HOLES — Two, screw holes for mounting the HED-1.0 to a stud or wall surface.
3. AM ANTENNA TERMINAL — Two, spring clip terminals for connecting the included AM Loop Antenna. POLARITY:
non-critical.
4. FM ANTENNA TERMINAL — One, F-type terminal for connecting the included FM Dipole Antenna.
