FUNCTIONAL DIAGRAM
DESCRIPTION OF ELEMENTS
HOW TO PERFORM THE WIRELESS LINK?
It is necessary to leave a DSP4 as Master and the other as Slave to establish a Bluetooth link.
After that, press the LINK key on both devices to associate one with the other. That’s it! Shortly, the Slave unit receives the signal via Bluetooth from the Master, and the Master can receive the signal via RCA or Bluetooth.
- LCD display for setup and monitoring
- Rotary encoder responsible for selecting and changing parameters
- Use these keys to select the channel to configured. If kept pressed, it mutes the selected channel
- Player Mode – Bluetooth audio mode. Just connect the smartphone via Bluetooth
Master Mode – It sends the signal via Bluetooth to another DSP4
Slave Mode – It receives the signal via Bluetooth from another DSP4 - Use ESC to return to parameter or previous menu
- Processor output channels, connect to amplifiers
- Input sensitivity adjustment (MIN 6Vrms/MAX 1Vrms)
- Signal inputs shall be connected to the player or table output
- Bluetooth audio antenna
- The power supply connector shall be powered with 12Vdc. The REM needs to be connected to player’s remote, and REM OUT is sent to amplifiers
- Configuration Bluetooth antenna
BLUETOOTH INTERFACE
- It is possible to set the Expert Electronics processors via Smartphone or Tablet using a didactic and intuitive interface. It makes the system alignment easier, which can be done in front of the system and in real time.
- The “Expert DSP STARX” app can be downloaded free from Google Play Store or Apple Store.

PAIRING
APP CONTROL | iOS AND ANDROID
- Download the app at Google Play Store or Apple Store.
Enable Smartphone Bluetooth.- Enable Smartphone location.
- Open the Expert DSP STARX app and it will display the processor model to be connected.
