6.2 Kabelverbindungen
Refer to the diagram below for typical wiring connections.

Bild: Draufsicht view of the RECOIL REQ7 equalizer, illustrating the various input and output connections for a car audio system.
- Power (RED wire): Connect to a fused +12V constant power source from the vehicle's battery.
- Ground (BLACK wire): Connect to a clean, solid chassis ground point in the vehicle. Ensure good metal-to-metal contact.
- Remote (BLUE wire): Connect to the remote turn-on output of your head unit or other switched +12V source. This turns the equalizer on/off with your audio system.
- Audioeingänge:
- RCA Inputs (MAIN IN / AUX IN): Schließen Sie RCA-Kabel von den Vor-/Unterbuchsen Ihres Autoradios an.amp outputs to the MAIN IN. Use AUX IN for additional RCA sources.
- High Level Inputs (HI INPUT): If your head unit does not have RCA outputs, connect the speaker wires directly to the HI INPUT terminals.
- Audio Outputs (FRONT OUT / REAR OUT / SUB OUT): Connect RCA cables from these outputs to the corresponding inputs on your external amplifizierer.
7. Bedienungsanleitung
7.1 Erstes Einschalten
- After completing all wiring, reconnect the vehicle's negative battery terminal.
- Turn on your head unit. The REQ7 should power on automatically via the remote wire.
- Start with all EQ bands at their center (flat) position, master volume low, and subwoofer level low.
7.2 Anpassen der Audioeinstellungen
- Quellenauswahl: Verwenden Sie die AUX S/W switch to toggle between the MAIN IN (RCA from head unit) and AUX IN (front panel 3.5mm or rear RCA auxiliary inputs).
- Master-Lautstärke: Erhöhen Sie langsam die VOLUMEN Stellen Sie den Regler auf eine angenehme Hörlautstärke ein.
- Subwoofer-Pegel: Passen Sie die UNTEREBENE knob to blend the subwoofer output with the main speakers.
- FADER Control: Verwenden Sie die FADER knob to balance the sound between the front and rear speakers.
- Ausgleich: Passen Sie die individuelle EQ-Band controls (50Hz, 125Hz, 315Hz, 750Hz, 2.2KHz, 6kHz, 16kHz) to fine-tune the audio frequency response to your preference. Increase (+) to boost a frequency, decrease (-) to cut it.
- Tiefpassfilter: Verwenden Sie die TIEFPASSFREQUENZ switch on the rear panel to select the desired crossover point (60Hz or 90Hz) for the subwoofer output. This ensures only low frequencies are sent to the subwoofer.
8. Wartung
