TK-Talkie App v1.x

The TK-Talkie App allows you to control your BLE-enabled TK-Talkie and allows you to easily customize your setup.

You can even create multiple settings profiles and easily switch between them, allowing you to use your TK-Talkie for a variety of costumes.

Connecting to a TK-Talkie

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.

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 these settings.

Each tab of the control screen is outlined below.

Volume

The volume tab allows you to control the inputs and outputs your device uses as well as input and output levels.

For example:

  • If you are using the microphone input, the microphone level setting can be used to control how strong the input gain is for the microphone.
  • 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.

Voice

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.

Effects

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 avoid feedback.

Sounds

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.
Please see the notes about sound files format.

EQ

The EQ panel allows you to further dial-in the perfect sound for your voice.

When enabled, the Equalizer is a 5-band graphic equalizer with the following bands (from left to right):

  • 115Hz (Bass)
  • 330Hz (Mid-Bass)
  • 990Hz (Mid)
  • 3kHz (Mid-Treble)
  • 9.9kHz (Treble)
The "classic" sound involves more mid band and less treble. Pushing the treble bands up too high can cause feedback.

Saving Configurations

After modifying a configuration, you can save it to the same or a new configuration by clicking the Save button.

You can also change the description of the configuration settings.

In addition, you can change the access code to your device by providing a new code.

Changing the Device Access Code

To change the device access code, click the Save button while editing a profile and enter a new access code.

Device Manager

The Device Manager allows you to add, remove or connect to different TK-Talkie devices.

Device Configrations Manager

The Device Configurations Manager allows you to manage settings configurations on the currently connected device.

To access the Device Configurations Manager, tap the cog icon next to the current profile name.

The currently loaded configuration will be marked with an asterisk (*)

The default profile that is loaded when the TK-Talkie starts will be marked by a solid star.

Sound File Format

The sound files used by TK-Talkie must be in .WAV format. They can be mono or stereo but should be 16-bit at 44,100Khz.

The SD card reader expects the files to be in old-school 8.3 format and all UPPERCASE. That is, the file name can have up to 8 characters and the extension has 3. For example: SOUNDFIL.WAV
