AKD7756-HF
AK7756 Hands Free Evaluation Rev.0
GENERAL DESCRIPTION
AKD7756-HF is a Hands-free evaluation kit for the AK7756 which is an audio processor with PCM
interface, EEPROM interface, mono voice audio CODEC and microphone pre-amplifier. A speaker
amplifier is integrated in this evaluation kit for easy evaluation of Hands-free function by connecting
external microphones and speaker units. It is possible to access to the AKD7756-HF via USB interface,
and adjustment of voice quality and noise attenuation level can be made with Windows GUI applications.
An external Flash Memory for DSP programming is integrated into this kit enabling a stand-alone
operation. In addition, an easy connection to a mobile phone is provided by integrated Blue Tooth module
for evaluations.

<Bluetooth Pairing>
• Power on the AKD7756-HF.
• Push and hold the HOOK button on front panel of the AKD7756-HF for more than seven seconds. When releasing
the button, LED of the status2 is ON and the AKD7756-HF becomes Bluetooth pairing wait state.
• Set a mobile phone into Bluetooth search state.
• Search result is displayed.
• Select [Free2move WA] from the search result and register it.
• Enter [0000] when password is required.
• Bluetooth registration complete message will be displayed.
• Select the registered machine and connect them when power-on the AKD7754-HF next time.
The peripheral search flow will not be the same way, depending on a mobile phone. (ex. A password for mobile
phone may be required) Please refer to the usage manual of the mobile phone for details.
<Call & Disconnect>
Receive: When hear the ring tone, push the HOOK button on front panel of the AKD7756-HF
Transmit: Push the HOOK button on front panel of the AKD7756-HF after making a call by mobile phone.
Disconnect: Push the HOOK button on front panel of the AKD7756-HF.
<Note>
The built-in Bluetooth module can register three mobile phones at a maximum. The fourth mobile phone can not be
registered when it already has three registered mobile phones. In this case, all registered mobiles should be
unregistered once to register the fourth mobile. The built-in Bluetooth module can be initialized by pressing the
HOOK button and BE-RST button in front panel of the AKD7756-HF for more than five seconds to cancel
registered mobiles.

■ Noise Canceller
The noise canceller sets optional noise attenuation for 6 divided voice bands.
This noise cancel adjustment is made with the real time NC parameter adjustment function of GUI software as shown
in the following diagram.
Sensitivity Adjustment
When it is high, sensitivity decreases,
and stability improves.
When it is low, sensitivity improves,
and stability decreases.
The noise attenuation of each band
is adjusted. Unit = [dB]
GAIN0= Lowest frequency band
GAIN5= Highest frequency band
Figure 6. Control S/W [NC Tune] tab screen
■ Parameter Adjustment
Set the parameters in CRAM to adjust Hands Free setting.
In this instruction manual, CRAM addresses are expressed as C (xx). Address = 4Ch is shown below as an example.
Example:
C(4Ch)
CRAM Address 4Ch
A corresponding example to the CRAM file is shown below.
