5. Nastavení a instalace

5.1 Zapojení kabeláže

Pro správné zapojení postupujte podle těchto kroků:

1. Power (+BAT): Connect the +BAT terminal to the vehicle's positive battery terminal using a fuse (not included) close to the battery.
2. Zem (GND): Connect the GND terminal to a clean, solid chassis ground point in the vehicle.
3. Vzdálený vstup (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 ampzáchranáři.
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 ampzáchranáři.

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. Návod k obsluze

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

6.1 Základní navigace

• Hlavní ovládací knoflík: Rotate to navigate menus and adjust values. Press to select an option or confirm a setting.
• LCD displej: Shows current menu, settings, and values.

6.2 Input and Output Management

• Vstupní kanály: The DSP 2.4X has two audio inputs (A and B).
• Výstupní kanály: It features four independent output channels.
• Výběr zdroje: 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 Vyrovnání

• Grafický ekvalizér: 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.
• Parametrický ekvalizér: 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 Other Controls

• omezovač: 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.
• Inverze fáze: Invert the phase of individual output channels to correct acoustic cancellations.
• Zvukový generátor: Built-in audio generator for system testing and tuning.

7. Údržba

The PRV AUDIO DSP 2.4X requires minimal maintenance.

• Čištění: K čištění vnější strany jednotky používejte měkký, suchý hadřík. Nepoužívejte agresivní chemikálie ani abrazivní čisticí prostředky.
• Spojení: Pravidelně kontrolujte všechna kabelová připojení, abyste se ujistili, že jsou bezpečná a bez koroze.
• Větrání: Ujistěte se, že větrací otvory nejsou zablokované, aby bylo možné správné odvádění tepla.
