Opsætningsvejledning
Før installation
- Plan your wiring layout carefully.
- Sørg for, at køretøjets batteri er frakoblet.
- Choose a mounting location that is dry, well-ventilated, and secure. Avoid mounting on carpet or in areas prone to vibration.
Ledningsforbindelser
The Quantum QB2150 amplifier features direct-connect integrated terminals for power, ground, remote, and speaker outputs. Refer to the image below for a visual representation of the amplifier's layout.
Billede: Top-down view of the Quantum QB2150 Beta Series 2 Channel Stereo Ampløfter, showcasing its heat sink fins, the Quantum Audio logo, and the input/output terminals on the side. The terminals include power, ground, remote, RCA inputs, and speaker outputs, along with fuse holders.
- Strømtilslutning (+12V): Connect a suitable gauge power cable (e.g., 8 AWG or 4 AWG depending on total system power) from the amplifier's +12V terminal directly to the positive terminal of the vehicle's battery. Install an in-line fuse holder within 18 inches (45 cm) of the battery.
- Jordforbindelse (GND): Connect a power cable of the same gauge as the +12V cable from the amplifier's GND terminal to a clean, unpainted metal point on the vehicle's chassis. Ensure a good electrical connection.
- Fjerntænding (REM): Connect a small gauge wire (e.g., 18 AWG) from the ampFjernbetjeningens REM-terminal til fjernbetjeningens tændingsudgang på din hovedenhed. Denne ledning tænder amptænd og sluk for støjrelæet med din hovedenhed.
- RCA-indgang: Connect RCA cables from the pre-amp outputs of your head unit to the RCA input jacks on the amplivligere.
- Højttaler output: Tilslut dine højttalere til amplifier's speaker output terminals. For stereo operation, connect one speaker to each channel. For bridged mono operation, refer to the amplifier's specific bridging instructions (typically using the positive terminal of one channel and the negative terminal of the other). Ensure correct polarity.
- Installation af sikringer: Insert the specified ATC 20 amp fuse into the amplifier's fuse holder.
Operation
Indledende opstart
- Når alle tilslutninger er foretaget og verificeret, skal køretøjets negative batteripol tilsluttes igen.
- Tænd din hovedenhed. ampApparatet skal tændes, hvilket indikeres af en lysende strøm-LED.
- Start med amplifier's gain control set to minimum.
- Play a familiar audio track at a moderate volume level on your head unit.
- Langsomt øge amplifier's gain control until the desired volume is achieved without distortion. Do not set the gain too high, as this can cause clipping and damage to speakers.
Justering af indstillinger
- Gain Control: Passer til amptransformerens indgangsfølsomhed i forhold til udgangsvolumentage of your head unit. Adjust for clean, undistorted sound.
- Bass Boost (45Hz, 0-12dB): Allows for an increase in bass output at 45Hz. Use sparingly to avoid distortion.
- Subsonic Filter (15-55Hz): (If applicable for specific configurations) Filters out extremely low frequencies that are inaudible and can waste amplifier power or damage subwoofers.
Opretholdelse
- Behold ampRengøring af apparatet er ren og fri for støv. Brug en blød, tør klud til rengøring.
- Sørg for tilstrækkelig ventilation omkring amplifier to prevent overheating. Do not block the heat sink fins.
- Kontrollér regelmæssigt alle ledningsforbindelser for tæthed og korrosion.
- Hvis amplifier's protection circuit activates (indicated by a protection LED), turn off the system, identify and resolve the issue, then restart.
Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Ingen strøm / ingen lyd | Sprunget sikring, dårlig strøm-/jordforbindelse, intet fjernsignal. | Check amplifier fuse, battery fuse, power and ground wires. Verify remote wire connection to head unit. |
| Forvrænget lyd | Gain set too high, poor speaker connection, damaged speaker, low input signal. | Reduce gain. Check speaker wiring for shorts or loose connections. Inspect speakers for damage. Ensure head unit output is clean. |
| AmpOverophedning af væske | Utilstrækkelig ventilation, for lav impedans, langvarig høj lydstyrke. | Sørg for god luftgennemstrømning omkring ampKontroller højttalerimpedansen. Reducer lydstyrken eller lad ampvarmebeholder til afkøling. |
| Beskyttelses-LED tændt | Short circuit in speaker wiring, amplifier overheating, DC offset. | Check all speaker wires for shorts to ground or each other. Allow amplifier to cool. Disconnect RCA inputs to check for DC offset from head unit. |
| Motorstøj / Hylen | Dårlig jordforbindelse, RCA-kabler for tæt på strømledninger, defekte RCA-kabler. | Forbedr jordforbindelsen. Omled RCA-kablerne væk fra strømledningerne. Prøv andre RCA-kabler. |
