reference
output
clock
for
external
subcarrier
gener-
ators
like
RDS.
This
is a

signal
with 0
to
+5V
transition
occurring
at
the
pilot
zero
crossing.
• Overshoot
Control
Limiter
limits
overshoot
to
less
than
0.5dB
with
minimum

provides
an

Inputs
The
left
and
right
analog
inputs
are on
XLR-type
female
connectors
on the
rear
panel.
Input
impedance is
greater
than
lOOkQ;
balanced
and
symmetrical.
Inputs can
accommodate
from
0 to
+15dBu
for
100%
modulation.
(OdBu
=
0.775Vrms).
Level
control
of the
analog
inputs
is
via the
screwdriver-adjustable
Left
and
Right Drive
controls,
located
on
the

as

bar
graph
(5

1
10%).
100% is
the
threshold
of
the
built-in

100%
on
this
