Introducing THAT-1
Connect THAT-1 between your
telephone and handset for quick
access to audio in and out of the
telephone. The THAT-1 is used by
radio stations to record and play
sound bytes, and by computer and
telephone companies to demonstrate
their computer voice services using a
powered speaker.
Play (Line In)
This is a line level input for signals
that you want to send down the phone
line. This jack can be connected to an
audio output such as the line output
from a computer or mixer, or the
headphone output from your music
player, laptop, phone, etc
Record (From Phone)
This is a variable mic level output from
the telephone.This jack provides a
mix of both sides of the conversation.
In other words, whatever you send
down the phone line will come back
on this jack mixed with the audio from
the other side of the call. This is not
adjustable.

Getting Connected
THAT-1 connects between the handset and the base of your telephone. Follow
these simple steps:
1. Unplug the modular handset cord from your telephone base.
2. Using the black handset jumper cord that we have provided, connect the
<Phone> jack of THAT-1 to the handset jack on your telephone base.
3. Plug your handset cord, and handset, into the <Handset> jack on THAT-1.
4. Using the supplied adapter cable…
A. Take the left channel from a 1/8" mini stereo headphone or line output jack
and attach it to the <Line In> RCA jack on THAT-1, or…
B. Connect the <From Phone> output jack to a mic level input on your
recording device.
5. Use the Handset/Line In button to choose your operation (see page 4).
Note: Not for use with telephones that have a keypad in the handset.

Operation
Handset/ Line In Button
The Handset / Line In button selects
which signal will be sent down the
phone line; the handset microphone,
or the line input jack.
Record (Position: Out)
Use the handset to speak and listen
as you normally would. The sound
that you hear on the handset is always
available on the <From Phone>
output jack.
Play (Position: In)
The handset mic is disconnected and
the line input is connected to send
audio signals down the line.
You can also use the Handset / Line
In button to turn o󰀨 the handset mic
if you are listening to the line output
signal over a loudspeaker. This
will prevent feedback between the
handset microphone and loudspeaker.
In any case you can always listen over
the handset receiver.
If a conict arises it will typically be
on the line input side. If you attempt
to send voice band signals down the
line input jack and the distant party
complains that the level is too loud
or severely distorted (clipping), try to
lower the transmit signal on your audio
equipment.

Note: Not all telephones are built alike so we
cannot guarantee THAT-1 will work with every
handset design available. We designed the
interface to work with most popular designs.

I have been using my THAT-1
for recording and it works
great but when I try to
send audio down the line it
won’t work.
Several things could be causing this
problem: First you must send a line
level signal into the <Line In> jack
on THAT-1. Second, make sure the
gray button is in the 'In' position.
This disables the handset mic and
enables the audio input. Third, the
phone you are using must have an
“electret” type mic in the handset. Not
all phones are the same and THAT-1
is only compatible for sending audio
with phones that have this microphone
type. You may want to consider our
THAT-2 which has a three position
switch to allow you to use it with
virtually any telephone.
FAQs
Can I get an adapter that will
allow me to connect THAT-
1 to the wall jack instead of
the phone?
No, your THAT-1 doesn’t replace
your phone,, but works in conjunction
with it. You will need to plug it in
between the telephone base and the
telephone handset.
Can I use THAT-1 with my
speakerphone?
You cannot use the speakerphone
function on your telephone and
THAT-1 at the same time. THAT-1
accesses the audio through the
handset cord. With the speakerphone
turned on, most telephones disable
the handset connection. Typically
there is no audio going through the
handset connection at the time.
