Bogen TPU-60B User Manual

Speakers
Speaker systems can be connected directly to the speaker out-
put terminals. The amplifier provides outputs at |6-ohm, 25VCT,
25V, and 70V, and is shipped for use with unbalanced systems.
_
Connect
one
lead
to
the
terminal
corresponding
to
the
imped-
ance of the speaker system and the other to the COM and GND
terminals on the output terminal strip.
Far balanced systems, remove the link between COM and GND.
Additional Power Amplifier
An external power amplifier can be used with the TPU amplifier.
You must modify the output circuitry of the telephone amplifier
by adding a resistor network, as illustrated below. Connect a
patch
cord
to
the
high-level/high-impedance
input
of
the
boost-
er amplifier.

Operation
Power
Plug
the
amplifier
line
cord
into
a
suitable
outlet.
The
POWER
LED
will
illuminate
once
power
is
applied
to
the
amplifier.
The
unit
remains
in
a
power
standby
condition
after
power
is
applied.
PEAK LEVEL
The
PEAK
LEVEL
LED
will
illuminate
if
the
amplifier
is
driven
into
clipping.
Adjust
the
output
level
of
MIC
VOLUME,

Controls
APHEX®
The
APHEX®
control
on
the
front
panel
adjusts
the
mix
of
the
Aphex
effect
with
the
audio
signal.
Clockwise
rotation
of
the
control
maximizes
the
effect.
Counterclockwise
rotation
mini-
mizes
the
effect.
To
turn
the
Aphex
circuit
on
or
off,
use
the
slide
switch
located
in
the
connections
bay
(See
INPUT
CONNECTIONS).
Treble & Bass
The
BASS
control
provides
+/-9dB
of
boost
and
cut
at
100Hz.
The
TREBLE
control
provides
+/-9dB
of
boost
and
cut
at
|OKHz.
Rotate
controls
clockwise
to
boost
and
counterclockwise
to
eut.
TEL INPUT
VOX (Voice-Operated) SENS
The
VOX
SENSitivity
control
should
be
set
so
that
only
the
desired
signal
is
above
the
threshold
level,
while
noise
or
unwanted
signal
is
below
it.
When
an
input
signal
(such
as
voice)
is
detected,
the
music
channel
will
be
muted.
To
adjust
the
sensitivity
of
this
circuit:
|.
Rotate
the
control
fully
clockwise.
While
making
a
page
announcement
and
talking
at
a
low
level,
the
sound
should
not
be
choppy
nor
missing
parts
of
words.
if
it
is
choppy,
or
if
intelligibility
is
poor,
rotate
the
control
counterclockwise
to
the
point
where
the
sound
is
clear
and
crisp
(but
not
to
the
maximum
counterclockwise
position).

If
the
background
music
shuts
down
when

This
control
differs
from
the

terminals
which
mute
background
music
during
a
microphone
page
(See
Input
Connections).
The
fully
counterclockwise
position
results
in maximum
muting.
The
fully
clockwise
position
results
in
minimum
muting.
