To connect to a device, start the TK-Talkie App and tap the green arrow button.
This will scan to find nearby BLE devices.
If there are already device profiles saved to the app, you can tap the
select list to choose them.
Only nearby BLE (Bluetooth-Low-Energy) devices will be displayed.
Once the scan is complete, you will see the device profile screen.
Provide a name for the device profile. This does not rename the device,
it is merely used for you to keep your devices organized in your app.
Tap the drop-down device list. If your device is not listed, make
sure it is powered on and tap the refresh button next to the drop-down
Select your TK-Talkie from the drop-down.
Enter the device access code for your TK-Talkie. You should have
received this code with your order. (Once you have connected to
your TK-Talkie device you can change this. See Changing Your Device Access Code.)
Once all required fields are complete, the Connect button will be activated. Tap it to connect to your device.
If there is an error connecting, a message will be displayed (for example: device access code is incorrect.)
Once your device is connected, the Control Screen will be displayed.
Device Control Screen
The device control screen allows you to control all aspects of your TK-Talkie.
When connected, the app will request the CURRENT settings profile that is
active on your TK-Talkie. The control screens will be updated to reflect
Each tab of the control screen is outlined below.
The volume tab allows you to control the inputs and outputs your device uses
as well as input and output levels.
If you are using the microphone input, the microphone level
setting can be used to control how strong the input gain is for the
If you are using the line-in port for your microphone, the line-in
level will control the signal strength.
It is a good idea to use the microphone input with non-powered microphones
(for example the wired microphones that come with the Aker amp). Line-in is
best for powered microphones (for example a wireless microphone headset.)
You can select which input by tapping the microphone or line-in toggle at
the top of screen.
The headphones output and the line-out are always active (but have
different output level controls) so you don't need to select which output
you are using.
Headphones Volume - The output level when using the
headphone jack. If you are connecting to a powered amp (speaker) such as
the Aker, it's a good idea to using the Line-Out jack instead to avoid
feedback since the headphone out jack is powered, creating a really "hot"
signal to the amp.
Microphone Level - The micrphone input level. This
connection should be used for non-powered (typically wired) microphones
as this is an amplified signal. Connecting a powered microphone (such as
a wireless mic) could cause feedback issues if this level is set too high.
Line-Out Level - Controls the signal strength of the
outgoing signal. The line-out is typically connected to the line-on of a
powered speaker (such as an Aker), letting the amplifier handle the volume.
Line-In Level - Sets the incoming signal strength of
a microphone connected to the line-in jack. This is typically used with
powered inputs such as a wireless microphone.
Radio Noise Volume - Controls the volume level of the
background static noise that is present when speaking, adding to the
overall radio-like effect.
The voice tab allows you to control voice volume as well as trigger levels
for voice activation.
Voice Volume - Valid values are from 0 to 10. This is the output
level for the voice channel (your voice.)
Voice-On Level - For VA (Voice Activated) mode, this is the level
the microphone input must reach in order to turn the voice channel
on. The voice channel stays off when not speaking. This setting has
no effect when using PTT (Push-To-Talk) mode.
Voice-Off Level - Once the voice channel is activated, this is the
input level that be reached in order to automatically turn it off.
This setting has no effect when in PTT (Push-To-Talk) mode.
Voice-Off Delay (ms) - This is the amount of time to wait once the
Voice-Off Level has been reached before adding any sound effects and
turning off the voice channel. This prevents the voice channel from
accidentally turning off if you pause quickly while speaking. A value
of 250 to 350 milliseconds (ms) is generally a good setting for a
more natural speaking experience.
The Effects panel lets you control the Bitcrusher effects that are applied
to your voice as you speak, giving it a more digitized radio sound.
Two separate bitcrushers are used to help achieve this, and you can set
both the bits and sample rate to better suit your voice.
The lower you set the bits the more digitized your voice
will sound, but be careful setting the bits and rate too low in order to
The Sounds panel lets you choose sound effects and files as well as set
volume levels (where applicable.)
Startup - This is the sound file that is played when
your TK-Talkie is first turned on.
Background Loop - This is the background sound file
that plays while your TK-Talkie is on. The file will start over once
the end is reached.
PTT Button Click - The sound file to play with the PTT
(Push-To-Talk) button is pressed.
