TEL
A balanced isolating transformer input for a telephone line is
provided.
A
600-ahm
telephone
line
may
be
connected
to
the
TEL
terminals.
If
two-conductor
shielded
wire
is
used,
connect
the
shield
to
the
adjacent
GND
(ground)
terminal,
which
is
to
the left of the TEL terminals.
MIC BAL & MUSIC MUTE
A
low-impedance
balanced
microphone
can
be
connected
to
the
screw
terminals
marked
MIC
BAL.
Use
two-conductor
shielded
wire
and
connect
the
shield
to
the
adjacent
GND
terminal.
Connect
the
MUSIC
MUTE
terminals
to
the
switch
on
the
microphone
for
microphone
muting
of
the
music
channel.
MUSIC IN
A
wide
range
of
HI-Z
background
music
sources
can
be
con-
nected
to
the
TPU
amplifier.
Connect
the
source
to
either
the
MUSIC
RCA
jack
or
MUSIC
IN
screw
terminals.
TEL RING & CONTACT RING
The
night
ringer
can
be
activated
either
by
a
90V
ring
signal
or
from
a
dry
contact
closure.
To
activate
the
night
ringer
using
the
ring
signal,
connect
the
sig-
nal
to
the
TEL
RING
terminals.
To
activate
the
night
ringer
using
contact
closure,
connect
a
pair
of
normally-open
dry
contacts
(customer-supplied
and
installed
in
the
telephone
system)
to
the
CONTACT
RING
terminal
and
adjacent
GND
terminal.
RINGER TONE
As
shipped,
a
steady
ringing
tone
will
be
heard
as
long
as
the
dry
contacts
remain
closed.
To
produce
a
pulse
tone,
it
is
necessary
to
remove
the
cover
and
place
the
jumper
located
at
J1
in
the
P
(Off)
position.
WARNING
This procedure requires removal of the amplifier cover.
To avoid an electric shock hazard, do not perform this
procedure unless you are qualified to do so.
APHEX®
The
Aphex®
Aural
Exciter
circuit
is
controlled
by
the
on/off
switch
located
in
the
input
connections
bay.
When
the
switch
is
in
the
on
position,
the
harmonics
that
are
usually
lost
in
the
amplification
process
are
regenerated
and
added
to
the
audio
signal.
This
results
in
increased
presence
and
clarity,
increased
intelligibility,
greater
perceived
loudness
(without
adding
extra
power)
and
reduced
listener
fatigue.
BRIDGING JACKS
Two
TPU
amplifiers
may
be
bridged
together
to
double
the
num-
ber
of
inputs
and
outputs.
Connect
a
single-conductor
shielded
cable,
terminated
in
an
RCA
phono
plug
at
each
end,
between
the
BRIDGING
jacks
of
the
two
amplifiers.
The
cable
should
not
be
more
than
20
feet
in
length.
Output Connections
Output
connections
are
housed
in
the
connections
bay,
accessi-
ble
by
removing
the
right
hand
cover
panel
on
the
front
of
the
amplifier.
Loosen
the
hold
down
screws
on
the
panel
and
slide
the
panel
up
to
remove.
Knockouts
are
provided
on
the
panel
to
admit
wiring.
Be

to
replace
the
cover
and
secure
the
hold
down
screws
after
