Functional Diagram

The functional diagram illustrates the signal processing path. Input signals, labeled IN L and IN R (maximum 4 Vpp), first pass through an Equalizer (EQ) with adjustable gain (-12dB to +12dB). The signal then proceeds through Routing, Mute, Channel EQ, Crossover, Limiter, Peak Limiter, Gain, Phase (0° or 180°), and Delay stages. These stages are applied independently to each of the four output channels (CH1, CH2, CH3, CH4). Each channel can be configured for stereo (L/R) or summed mono (L+R) routing. The processed signals are then sent to the outputs (OUT 1, OUT 2, OUT 3, OUT 4), with a maximum output level of 10 Vpp.

Description of Elements

The front panel features:

• (1) LCD display: For configuration and monitoring.
• (2) Rotary encoder: Responsible for parameter selection and changes.
• (3) Keys: Used to select the channel to be configured. Can be used within any menu. On the home screen, they change the selected channel.
• (4) ESC button: Used to go back to the previous parameter or menu.

The rear panel connections include:

• (5) Processor output channels: Connect to the amplifiers.
• (6) Input sensitivity adjustment: Range from 2 to 6 Vrms.
• (7) Signal inputs: Must be connected to the output of the player or mixer.
• (8) Power connector: Requires a 12Vdc supply. The REM IN terminal must be connected to the player's remote output, and the REM OUT terminal sends the remote signal to the amplifiers.
• (9) Bluetooth antenna: Available only for the Connect Line model.

Bluetooth Connection (Available only for Connect Line model)
