Audio Control A1500.1 ALTITUDE MONOBLOCK AMPLIFIER

The AudioControl A1500.1 Altitude Monoblock Amplifier is a high‑performance, 1‑channel Class D powerplant engineered for serious subwoofer duty in premium builds, delivering substantial current with refined thermal management. Its sleek anodized matte grey aluminum chassis concentrates power where it counts, while a feature set aimed at enthusiasts provides precise control and protection.

• Output power at 4Ω / 2Ω / 1.33Ω: 600W x 1 @ 4Ω; 1200W x 1 @ 2Ω; 1500W x 1 @ 1.33Ω. In real terms, this provides strong, clean bass with headroom for dynamic music passages and demanding subwoofer loads without clipping at typical car power levels.
• High‑efficiency Class D with PWM modulator: The PWM‑driven design minimizes heat and maximizes efficiency, letting the amp sustain high output in tight automotive environments while reducing overall cooling demands.
• Anodized matte grey aluminum chassis: The rugged housing aids thermal dissipation and corrosion resistance while maintaining a sleek, low‑profile appearance in a modern install.
• ParaBASS Low Frequency Contouring: Fine‑tune the bass response to taste or room in a stereo/sub setup, balancing punch and extension to suit your vehicle's acoustics.
• Valet Mode: When activated, limits maximum volume to 25% to protect sensitive speakers and prevent unintended damage during daily driving.
• Spike Mode: Enables wiring three 4Ω subwoofers at 1.33Ω, increasing total bass potential while designed to run cool at maximum output for extended periods.
• Start‑Stop compliant and EV up to 17V: Ready for modern vehicle electrical systems, maintaining performance in start‑stop and electric vehicle environments.
• GTO Signal Sense: Integrated signal sensing for responsive on/off and input behavior aligned with your source signal.
• Linkwitz‑Riley Crossovers and Subsonic/Low‑Pass controls: Offers clean, predictable frequency separation; Subsonic Filter is variable, and Low Pass range is 60 Hz to 120 Hz for precise sub integration.
• Optional Remote Level Control (ACR‑1): Gives you convenient adjustment of bass levels from a preferred dash or seating position.
• Inputs: Preamp inputs (2) and Line‑Level inputs up to 6 V, with Speaker‑Level inputs up to 20 V, enabling flexible integration with factory radios and aftermarket head units.
• Dimensions & weight: 12.5" W x 6.7" D x 2.1" H; 7.15 lbs, a compact footprint for a high‑power monoblock that fits a wide range of vehicles.
• Performance specs: S/N 103 dBA; THD+N < 0.11%, indicating low noise and distortion at rated power for clear, tight bass with minimal coloration.

In a premium install, the A1500.1 excels as the powerhouse behind a dedicated subwoofer system or multi‑sub array, pairing well with AudioControl’s PNW speakers and Space or Spike subwoofers. Its ParaBASS shaping, precise Linkwitz‑Riley crossovers, and robust protection features yield a controlled, high‑fidelity bass foundation while Start‑Stop/EV compatibility and Valet Mode protect both your system and your driving experience. Optional remote control and Spike Mode provide additional tuning and power flexibility for extended, high‑energy bass in long drives or audiophile builds.
