Audio Control A1100.5 ALTITUDE 5-CHANNEL AMPLIFIER

The AudioControl A1100.5 Altitude 5-channel amplifier is a high-efficiency multi-channel powerhouse designed for performance-focused installs in modern vehicles. Its anodized matte grey aluminum chassis and advanced power electronics deliver clean, capable output with smart protections.

• Power outputs: 90W x 4 @ 4Ω and 400W x 1 @ 4Ω; 125W x 4 @ 2Ω and 600W x 1 @ 2Ω. These figures let you run a four-channel front stage while dedicating a single channel to a sub, or push a high‑current sub at 2Ω for serious bass headroom.
• Valet Mode: Limits maximum volume to 25% when activated, helping prevent unintended loud bursts in parked or unattended vehicles.
• EV and Start-Stop compatibility: Start-Stop systems and electric vehicles are supported, with up to 17V EV compliance, ensuring consistent performance in modern vehicles.
• ParaBASS® low-frequency contouring: Built-in bass shaping to refine low-end response and tailor bass performance to the install environment.
• Inputs and source flexibility: 6 Preamp Inputs and 6 Line-Level Inputs (6V max) plus 20V max for Speaker-Level Inputs, enabling easy integration of diverse source signals and high-level inputs.
• Advanced power electronics: PWM modulator with HEXFET Power MOSFETs, premium toroidal transformer, low ESR capacitors, and 500V Class X2 capacitors with self-healing properties provide efficient, reliable power delivery and protection; the design also includes high‑efficiency ferrite core inductors and a high‑performance PWM driver IC with protection.
• Protection and tuning features: High/Low Input Modes, Linkwitz-Riley crossovers (X-Over Off by default), Subsonic Filter (variable), and optional Remote Level Control (ACR-1) for convenient on-dash adjustment.
• Physical specs and build: 14" W x 6.7" D x 2.1" H, 7.95 lbs, designed with an anodized chassis for thermal dissipation and a sleek profile suitable for under-seat or trunk installations.
• In the box: A1100.5, Manual, Warranty.

The A1100.5 is tailored for multi-amp systems that demand clean, efficient power with precise bass control and flexible input options. It suits builds where a four‑channel front stage is paired with a dedicated sub, or where a single high-current channel is required for low-impedance subs, all while maintaining thermal stability and EV compatibility in modern vehicles.
