1. Įvadas ir pabaigaview
The ESX QUANTUM QS-FOUR is an ultra-compact 4-channel Class D amplifier designed to significantly upgrade your car audio system. This powerful yet miniature 4-channel version measures only 90 x 35 x 80 mm, making it one of the smallest amplifiers in its class. It delivers an impressive 4 x 60 Watts RMS, providing substantial power to factory or aftermarket speakers.
The QS-FOUR features exceptionally low distortion (THD+N < 0.007% at 5W/RMS) and high efficiency (up to 90%), ensuring clear and dynamic sound reproduction. Its compact size allows for flexible installation, often directly behind the dashboard, making it an ideal plug-and-play solution for vehicles. The amplifier's low current draw (5-10 Amps) means it can often utilize existing factory power cables. Additionally, the QS-FOUR includes low-level outputs for connecting active subwoofers or larger monoblock amplifiers, offering expandability for enhanced bass.
2. Saugos informacija
- Prieš pradėdami bet kokius montavimo darbus, visada atjunkite automobilio akumuliatorių, kad išvengtumėte trumpųjų jungimų ir pažeidimų.
- Professional installation is recommended. Incorrect wiring can cause serious damage to the ampgelbėtojas, transporto priemonė ar asmens sužalojimas.
- Ensure all wiring is properly insulated and secured to prevent short circuits and vibrations.
- Neįdiekite amplifier in locations exposed to moisture, excessive heat, or direct sunlight.
- Maitinimo ir garsiakalbių jungtims naudokite tinkamo skersmens laidus, kaip nurodyta įrengimo skyriuje.
- Protect all power cables with an inline fuse located close to the battery.
- Venkite dėti amplifier where it could obstruct vehicle controls or safety devices.

5.1 Laidų jungtys
Before making any connections, ensure the vehicle's battery is disconnected. Refer to the diagrams below for proper wiring.
Maitinimo įvestis:
- + 12 V: Connect to the positive terminal of the car battery via an inline fuse (not included, but a fuse holder is provided).
- BND: Connect to a solid, unpainted metal point on the vehicle chassis. Ensure a good ground connection.
- REM (nuotolinis): Connect to the remote output of your head unit. If using high-level inputs with Auto-Turn-On, this connection may not be necessary.
Garsiakalbio išvestis:
Connect your speakers to the designated terminals. Ensure correct polarity (positive to positive, negative to negative). The amplifier supports 4-channel stereo or 2-channel bridged operation.
- FL+/FL-: Priekinis kairysis garsiakalbis
- FR+/FR-: Priekinis dešinysis garsiakalbis
- RL+/RL-: Galinis kairysis garsiakalbis
- RR+/RR-: Galinis dešinysis garsiakalbis
- Tiltas režimas: For 2-channel operation, connect the positive of the left speaker to FL+ and the negative to FR-. For the right speaker, connect positive to RL+ and negative to RR-. Refer to the manual for specific bridging instructions.
Įvesties jungtys:
- Aukšto lygio įvestis: Use the provided harness to connect to your head unit's speaker outputs. The EPS (Error Protection System) ensures compatibility with various factory systems.
- RCA Line-Out: Use the RCA cables to connect to an active subwoofer or another ampgyvesnis.
5.2 Pradiniai nustatymai
- Level Input (Gain): Start with the gain knobs set to minimum (MIN). Gradually increase the gain until the sound is clear and distortion-free at your desired listening volume. Avoid setting the gain too high, as this can introduce distortion.
- KRISTOMOSIOS DALYS (kryžminis filtras):
- PILNAS: Full range audio (no filter).
- HP (aukšto dažnio): Allows frequencies above 80 Hz to pass, typically used for full-range speakers to remove bass.
- LP (žemo dažnio dažnis): Allows frequencies below 80 Hz to pass, typically used for subwoofers (though this amplifier is not primarily for subwoofers, it can be used for mid-bass applications).
- AUTO TURN-ON:
- IŠJUNGTA: Amplifier turns on via the REM wire.
- VOX: Amplifier turns on when an audio signal is detected (signal sensing).
- DC: Amplifier turns on when a DC offset is detected on the high-level inputs (common with factory head units).
6. Naudojimo instrukcijos
Once properly installed and configured, the ESX QUANTUM QS-FOUR amplifier operates automatically with your vehicle's audio system.
- Maitinimo įjungimas/išjungimas: The amplifier will power on and off with your head unit, depending on the selected AUTO TURN-ON mode (REM, VOX, or DC). The 'POWER' LED on the rear panel will illuminate when the ampkeltuvas aktyvus.
- Garso atkūrimas: Play audio through your head unit as usual. The amplifier will provide enhanced power and clarity to your speakers.
- Garso reguliavimas: Control the overall system volume using your head unit. If distortion occurs at high volumes, slightly reduce the amplifier stiprinimo nustatymas.
- Apsaugos režimas: If the 'PROTECT' LED illuminates, the ampLizatorius įsijungė į apsaugos režimą dėl problemos (pvz., trumpojo jungimo, perkaitimo, žemos įtampos)tage). Turn off your audio system and vehicle, then troubleshoot the cause before restarting.
7. Priežiūra
- Valymas: Valymui naudokite minkštą, sausą šluostę ampišorę. Nenaudokite stiprių cheminių medžiagų ar abrazyvinių valiklių.
