OPTIMOD-FM DIGITAL
A momentary pulse of voltage will switch most functions except as noted.
• Preset Name: switches that preset on the air. Any factory or user preset
may be recalled via the control interface.
• Input: Analog: selects the analog inputs.
• Input: Digital: selects the digital input. No J.17 de-emphasis is applied to
the digital input.
• Input: Digital+J.17: selects the digital input and applies J.17 de-emphasis to
the digital input.
• Bypass: switches the Bypass Test Mode on the air.
• Tone: switches a Tone Test on the air.
• Exit Test: If a test mode (Tone or Bypass) is switched on the air,
reverts to the normal operating mode using the previous processing preset.
• Stereo: switches the 8500S's stereo encoder on using normal double side-
band modulation of the stereo subchannel.
• SSB:. switches the 8500S's stereo encoder on using compatible single side-
band/vestigial sideband modulation of the stereo subchannel. See SSB Ste-
reo Encoder Operation on page 3-10.
• Mono From Left, Mono From Right, or Mono From Sum: switches the
8500S's stereo encoder off, using the Left, Right, or Sum (L+R) respectively,
as the program source.
• MOD Reduction 1, or MOD Reduction 2: reduces the program modula-
tion by the percentage programmed in the Input/output screen. When volt-
age is removed, these functions are deactivated.
• Reset Clock To Hour
• Reset to Midnight
• Monitor Mute is a non-latching function that mutes the analog output if
it has been programmed to emit the monitor signal (in the I
O 1 screen).
UTPUT
• Analog Out Delay In: Activates the diversity delay for the analog output
if it is configured to emit the output of the analog FM processing chain (see
page 3-67).
• Digital Out 1 Delay In: Activates the diversity delay for Digital Output #1
(Analog, Digital #1, Digital #2, Composite) if it is configured to emit the
output of the analog FM processing chain (see page 3-67). There is also a
