Introducing Daptor Two
Simply plug Daptor Two into the
headset jack of any wireless phone
or notebook computer that accepts a
third party headset or earpiece. Send
and receive voice band or HD Voice
quality audio during regular calls, or
full bandwidth audio using third party
codec applications.
Daptor Two will provide the highest
quality connection possible between
your audio equipment and cellular
telephone. However, due to the
unpredictable nature of wireless
telephone service we cannot guarantee
excellent audio quality every time
Daptor Two is used. Audio quality
is still mostly dependent upon the
connection provided by your wireless
telephone service. As a general rule,
the better the cell phone signal, the
better your audio quality will be.
You should also keep in mind that
most wireless telephones have their
own level controls. The rst step in
setting levels should be adjusting your
phone volume control to obtain a clear,
healthy signal. You may then adjust the
gain on your other audio equipment to
ne tune the levels.

Setup
1. Connect the included CN113 cell
phone interface cable between the
<Wireless Phone Headset Jack>
of Daptor Two and the 3.5 mm
TRRS headset jack of your wireless
phone or notebook computer.
Note: Wireless phones generate substantial
radio frequency (RF) noise during a call which
can leak into your audio cables and equipment.
If you notice a problem with RF noise, be sure
to keep your wireless phone one to two feet
from your mixer and other audio equipment. It
is alsoimportant to keep the wireless adapter
cord away from any other audio cords.
2. Connect either <From Phone>
output to any Mic Level input
on your mixer or other audio
equipment. You may use either the
XLR output or 1/4" output, not both.
3. Connect the mixer’s Mix-Minus bus
or Aux Send output (this may be
labeled FX or Mon but any Aux bus
will work) to either <Line Input> on
Daptor Two. You may use either the
XLR input or 1/4" input, not both.
4. Whichever input channel that
Daptor Two's <From Phone>
output is connected to, turn the
corresponding Aux control to
minimum. All Aux controls for other
channels should be set for audio
sent to the phone line. Each Aux
Send bus is completely separate
from all other outputs, so these Aux
controls will not a󰀨ect what is heard
on the Main outputs or on any other
Aux buses.
Tip: Using anAux Send bus that is Pre-
Fader allows you to control the levels of
each channel to the main output without
a󰀨ecting what is sent to the phone line.

Setup
If your mixer does not have
an <Aux Send> bus, you can
use <Pan> controls with the Left
and Right outputs. Pan all the
microphones, etc. to the Left
output and pan the Caller to the
Right output. Then connect only
the <Left> output to the innkeeper
PBX <Send 1>. Or, you may use
an external Mix-Minus box that will
create this signal for you.
5. Your device will recognize Daptor
Two as a headset which will dis-
able the internal mic and speaker.
Connect a microphone and
headphones to your mixer or other
audio equipment. You are now able
to place or receive a call.
Wireless Phone Compatibility
Daptor Two emulates the electrical
characteristics of cell phone headsets
and should work with any wireless
phone that accepts generic third
party headsets. However, we cannot
guarantee that Daptor Two will work
with every wireless phone available.
With the increasing number of wireless
phones that now use non-standard
headset jacks, you may need to
separately purchase an adapter to
connect to our CN113 3.5mm TRRS
cable. These adapters are sometimes
provided with phones that do not use
standard headset jacks. If in doubt,
check with your phone manufacturer
for details about compatibility with
generic TRRS headset connections.

FAQs 5
Will Daptor Two work with my
model ____ cell phone?
Yes, as long as your wireless phone
has a 3.5 mm earpiece jack and
accepts a generic 3rd party earpiece
or headset.
What if my phone does not
have a 3.5 mm headset jack?
Many phone manufacturers provide
adapters that allow connection of a
3.5 mm plug. You can often nd these
adapters where you purchased your
phone or in electronics stores.
Can I send and receive audio
at the same time?
Yes. Daptor Two is capable of sending
and receiving audio at the same time.
Can I talk on my handheld
phone and record
the conversation using a
Daptor Two?
No, most phones detect the presence
of anything plugged into the headset
jack and immediately disable the
phones microphone and speaker.
Why is the audio so
loud/quiet?
The rst step in setting levels
should be adjusting your phone
volume control to obtain a clear,
healthy signal.
You may then adjust the gain on your
other audio equipment to ne tune
the levels.
