Hold down the D
meter indicates an average of 10 dB gain reduction.
The procedure does not apply to the 8500S's stand-alone stereo encoder
mode. In this mode, the level indicated on the screen during this step is
the r.m.s. level (in dBFS) of a 50 Hz input tone that produces 100% peak
modulation at the 8500S's composite output when the 8500S's C

10. Configure the analog outputs.
A) Set analog output feed.
a) Press the Next button.
b) Turn the knob to choose FM, FM+Delay, Monitor, or HD.
The HD selection will only be available if your unit is an 8500S/HD
B) Set analog output to be flat or pre-emphasized.
a) Press the Next button.
b) [Skip this step if you will not be using the analog left/right outputs.]
Turn the knob to choose P
If you will use the analog output to drive a stereo encoder, P
the best performance because the stereo encoder that receives the ana-
log output does not have to restore the pre-emphasis. However, if you
cannot defeat the pre-emphasis in your stereo encoder, or if you will use
the analog output for monitoring, set the output F
If you are sending the analog output of the 8500S through a digital link
that uses lossy compression (like MPEG, APT-X, or Dolby), set the output
.
F Lossy codecs cannot handle pre-emphasized signals.

11. Configure the digital outputs
A) Assign sources to Digital Outputs #1 and #2.
The instructions in this step 11 assume that your unit is an 8500S/HD and
that you are using Digital Output #2 to drive your analog FM transmitter
and Digital Output #1 to drive the HD input of your transmission system.
a) Press the Next button.
b) Turn the knob to assign FM or FM+D

c) Press the Next button.
d) Turn the knob to assign HD as the source driving Digital Ouput #1.
If your unit is an 8500S/FM, HD will not be available as an option. In this
case, you may wish to configure Digital Output #1 as a second FM output
to drive a standby exciter (by choosing FM or FM+D
