An
output
cable, made
up
with
connectors,
and
an
input
connector
are supplied
with
each
AM-1 manu-
factured. When ordering the
transformer
remember
to
specify
which
instrument
it
is
to
be
used
with
,
so
that
the proper
connector
can
be
provided at the
amplifier
end
of
the cable. When making
up
cables
for
connect-
ing
to
the
input
and
to
the
output,
use
Cannon brand
audio connectors
type
XLR-3-11C
or
XL-3-11C,
or
equ ivalent. Coaxi
al
cab I e
sh
ou
Id
be
used, preferably
of
short
length and
of
the low-noise variety
(Amphenol
RG/U
type
21
-537 or 21-541). Figure
111-8B
indicates
that
the center
conductor
of
the
output
cable should
be
wired
to
pin 2 and the shield
wired
to
pin
1. A BNC
connector
should
be
installed at the
amplifier
end
of
the cable.
Note
the resonance peak
at
the high frequency end
of
the
transformer
response curve (Figure 111-9A).
If
the
input
signal
has
frequency components in this range
the ampl
ifier
may
b~
prematurely overloaded
by
them,
particularly
at high signal or gain levels.
If
high
frequency signal components
cause
such problems the
operator
may consider
prefiltering
the signal or chang-
ing the source impedance
to
flatten
the response curve
in this range.
CAUTION:
Be
careful
to
avoid
applying
a signal
to
the
primary
such
that
will
cause
insulation breakdown
of
the secondary or damage
to
the
input
circuit
of
the
amplifier.
CAUTION:
Avoid
passing excessive
dc
current
through
the
primary
of
this transformer. More than
200
/lA
will
nagnetize the core. Core magnetization
will
cause
thE
transformer
to
saturate prematurely
for
one
polarity
f
ac
signal, resulting in
distortion
of
high
level signals, md a magnetized
transformer
is
usually
111-7
noisy and
microphonic,
causing
low
level
distortion
as
well.
See
paragraph (4)
for
a discussion
of
this
distortion
and a procedure
for
degaussing the trans-
former.
Do
not
measure winding resistance with
an
ohmmeter;
ohmmeter
current
is
sufficient
to
magne-
tize
the
core.
