1. הקדמה און איבערview
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.

5. סעטאַפּ און ייַנמאָנטירונג
5.1 וויירינג קאַנעקשאַנז
Before making any connections, ensure the vehicle's battery is disconnected. Refer to the diagrams below for proper wiring.
מאַכט אַרייַנשרייַב:
- + 12 וו: Connect to the positive terminal of the car battery via an inline fuse (not included, but a fuse holder is provided).
- GND: Connect to a solid, unpainted metal point on the vehicle chassis. Ensure a good ground connection.
- REM (ווייַטקייט): Connect to the remote output of your head unit. If using high-level inputs with Auto-Turn-On, this connection may not be necessary.
רעדנער רעזולטאַט:
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-: פראָנט לינקס רעדנער
- FR+/FR-: פראָנט רעכט רעדנער
- RL+/RL-: דער הינטערשטער לינקער רעדנער
- RR+/RR-: הינטער רעכט רעדנער
- בריקעד מאָדע: 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.
אַרייַנשרייַב קאַנעקשאַנז:
- הויך-מדרגה אַרייַנשרייַב: 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 ampליפער.
5.2 ערשט סעטטינגס
- 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.
- X-OVER (קראָסאָוווער):
- פול: Full range audio (no filter).
- ה.פ. (הויך דורכגאַנג): Allows frequencies above 80 Hz to pass, typically used for full-range speakers to remove bass.
- LP (נידעריק פּאַס): 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:
- OFF: 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. אַפּערייטינג ינסטרוקטיאָנס
Once properly installed and configured, the ESX QUANTUM QS-FOUR amplifier operates automatically with your vehicle's audio system.
- מאַכט אויף / אַוועק: די 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 ampליפיער איז אַקטיוו.
- אַודיאָ פּלייבאַק: Play audio through your head unit as usual. The amplifier will provide enhanced power and clarity to your speakers.
- אַדזשאַסטינג באַנד: Control the overall system volume using your head unit. If distortion occurs at high volumes, slightly reduce the ampליפיער'ס געווינס סעטטינג.
- שוץ מאָדע: If the 'PROTECT' LED illuminates, the ampדער לייטווער איז אריין אין שוץ מאָדע צוליב א פראבלעם (למשל, קורץ קרייז, איבערהיצונג, נידעריגער וואָלומען)tage). Turn off your audio system and vehicle, then troubleshoot the cause before restarting.
