AudioControl Altitude A1100.5 Five-Channel Amplifier for Superior Audio Systems

The AudioControl Altitude A1100.5 is a cutting-edge five-channel amplifier designed to deliver exceptional audio quality and versatility for premium home theatre and audio setups. Engineered for enthusiasts who demand superior performance, this amplifier ensures every note, dialogue, and effect is heard with stunning clarity and depth.

Key Features:

High/Low Input Modes:
High-Level Input Mode allows you to connect the amplifier to a factory radio or any source that doesn't have RCA outputs, using speaker-level inputs.
Low-Level Input Mode is for connecting the amplifier to a system with an RCA output (e.g., an aftermarket head unit), which typically provides a cleaner, more powerful signal for optimal sound quality.

GTO™ Signal Sense:
GTO (Greater Than Output) Signal Sense is an automatic turn-on technology. It senses the incoming signal from the head unit and automatically powers the amplifier on and off. This eliminates the need for a separate remote turn-on wire, simplifying the installation.

Linkwitz-Riley Crossovers:
The Linkwitz-Riley crossover design is a sophisticated filter used to separate the frequencies for different channels (like separating bass for a subwoofer and higher frequencies for midrange/tweeters). It ensures smoother transitions between frequency bands, reducing distortion and improving overall sound clarity. The A1100.5 likely offers both high-pass and low-pass filters, allowing for more precise frequency management.

Start-Stop Compliant:
This feature ensures that the amplifier is compatible with modern vehicles that use start-stop technology (where the engine turns off at idle to save fuel). The A1100.5 can handle the power demands and electrical fluctuations that may occur when the engine stops and starts, ensuring stable performance without noise or shutdown issues.

High Power Output in a Sleek Chassis:
Despite the compact design, the A1100.5 delivers high power output (up to 1100 watts) with efficient Class D technology. Class D amps are much smaller and lighter than older technologies (like Class AB) and are highly efficient, converting more power into output and generating less heat.

ParaBASS® Low Frequency Contouring:
ParaBASS® is a proprietary AudioControl feature that allows users to adjust and enhance low-frequency output (bass). This is especially useful for fine-tuning subwoofer performance and adding more control to the bass without overdriving the system.

Valet Mode Option:
Valet Mode limits the amplifier's power or functionality when enabled, which can be useful when handing your car over to someone (like a valet) to prevent misuse or damage. It ensures the amp can’t be cranked up too high, protecting your system while maintaining control.

Optional Remote Level Control (ACR-1):
The ACR-1 remote level control is an optional accessory that allows you to adjust the bass output from the front of the vehicle while driving. This is especially useful when you want to fine-tune the subwoofer level without needing to reach for the head unit or amplifier.

EV Compliant up to 17V:
The amplifier is EV (Electric Vehicle) compliant, meaning it can operate efficiently in electric and hybrid vehicles, which may have higher-than-normal voltage levels. The 17V tolerance ensures that the A1100.5 can handle power from these vehicles without issues, making it a good choice for modern cars, especially electric ones.
