5. Nastavitev in namestitev

5.1 Žične povezave

Za pravilno ožičenje sledite tem korakom:

  1. Power (+BAT): Connect the +BAT terminal to the vehicle's positive battery terminal using a fuse (not included) close to the battery.
  2. Ozemljitev (GND): Connect the GND terminal to a clean, solid chassis ground point in the vehicle.
  3. Oddaljeni vhod (REM IN): Connect the REM IN terminal to the remote output of your head unit or ignition switch. This signal turns the DSP on and off.
  4. Audio Inputs (A, B): Connect your head unit's RCA outputs to the DSP's Input A and Input B.
  5. Audio Outputs (1, 2, 3, 4): Connect the DSP's RCA outputs (1-4) to the inputs of your amposvežilci.
  6. Remote Output Sequencer (AMP S1, S2, S3): These outputs provide sequential triggering for external amplifiers or other accessories. Connect these to the remote input terminals of your amposvežilci.

5.2 Sequencer Feature

The DSP 2.4X includes a built-in sequencer feature that allows for sequential activation and deactivation of connected devices, such as amplifiers, via the remote trigger connection (REM). This helps prevent turn-on/turn-off thumps and protects your audio system components.

  • The sequencer has three outputs (S1, S2, S3).
  • These outputs are activated and deactivated sequentially based on the REM IN signal.
  • The triggering interval between each output can be set from 0s to 4s.
  • If the interval is set to 0s, all three outputs will activate/deactivate simultaneously after a 3-second delay from the REM IN signal change.
  • Use cables of at least 20 AWG for remote signal connections.

6. Navodila za uporabo

The DSP 2.4X is controlled via its LCD display and main control knob.

6.1 Osnovna navigacija

  • Main Control Knob: Rotate to navigate menus and adjust values. Press to select an option or confirm a setting.
  • LCD zaslon: Shows current menu, settings, and values.

6.2 Input and Output Management

  • Vhodni kanali: The DSP 2.4X has two audio inputs (A and B).
  • Izhodni kanali: It features four independent output channels.
  • Izbira vira: For each output, you can select the audio source from Input A, Input B, or a combination of A + B.
  • Output Select / Hold to Mute: Use the dedicated buttons to select outputs for adjustment or hold to mute.

6.3 Izenačitev

  • grafični izenačevalnik: A 15-band graphic equalizer is integrated. You can manually tune it or select from 12 preset options: Flat, Loudness, Bass Boost, Mid Bass, Treble Boost, Powerful, Electronic, Rock, Hip Hop, Pop, Vocal, and Pancadão.
  • Parametrični izenačevalnik: Features one input and one output parametric equalizer. This allows for fine adjustments with gain control, specific frequency setting, and adjustable equalizer bandwidth.

6.4 Digital Crossover

The digital crossover allows precise frequency distribution to different speakers.

  • Configure high-pass, low-pass, and band-pass filters for each output channel independently.
  • Adjust filter slopes and types (e.g., Butterworth, Linkwitz-Riley).

6.5 Drugi nadzorni mehanizmi

  • Omejevalnik: Protects speakers from over-excursion by limiting the output signal level.
  • Alignment (Delay): Adjust time alignment for each output channel to ensure all sound waves reach the listener simultaneously.
  • Fazna inverzija: Invert the phase of individual output channels to correct acoustic cancellations.
  • Generator zvoka: Built-in audio generator for system testing and tuning.
