OPERATION ORBAN MODEL 8700i
When this field is highlighted, press the Enter button to toggle between coarse and
fine adjustment. In PC Remote, drag the slider of the control with the mouse to set
the delay coarsely, use the Page Up and Page Down keys for intermediate incre-
ments, and use the mouse wheel to fine-tune the delay in one-sample adjustment
increments.
Maximum available delay is approximately 13 seconds.
See the documentation provided with your HD Radio exciter for more in-
formation on setting the delay correctly.
You can adjust the diversity delay time via the 8700i’s API. See page 2-54.
St. / Mono (“HD Output Stereo / Mono Mode”) determines if the digital-channel
output will be fed by the normal stereo output of the HD processing chain or by a
mono feed from the HD processing chain’s left channel, right channel, or sum of left
and right channels. In all cases, the signal appears on both the left and right chan-
nels of the analog and digital outputs.
The 8700i does not set the AES3 stereo / mono status bits to reflect the
setting of this control. The AES3 status bits appearing at the HD output
are always set “stereo” even when the two audio channels carry identical
mono signals.
HD Bandwidth sets the audio bandwidth of the HD output from 15 to 20 kHz in
1 kHz steps.
The user should carefully test the codec in use to ascertain if lowering the
