5.1 వైరింగ్ కనెక్షన్లు

Follow these steps for proper wiring:

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

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. ఆపరేటింగ్ సూచనలు

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

6.1 ప్రాథమిక నావిగేషన్

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

6.2 Input and Output Management

• ఇన్‌పుట్ ఛానెల్‌లు: The DSP 2.4X has two audio inputs (A and B).
• అవుట్‌పుట్ ఛానెల్‌లు: It features four independent output channels.
• మూలం ఎంపిక: 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 సమీకరణ

• గ్రాఫిక్ ఈక్వలైజర్: 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.
• పారామెట్రిక్ ఈక్వలైజర్: 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

• పరిమితి: 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.
• దశ విలోమం: Invert the phase of individual output channels to correct acoustic cancellations.
• ఆడియో జనరేటర్: Built-in audio generator for system testing and tuning.

7. నిర్వహణ

The PRV AUDIO DSP 2.4X requires minimal maintenance.

• శుభ్రపరచడం: Use a soft, dry cloth to clean the exterior of the unit. Do not use harsh chemicals or abrasive cleaners.
