AudioControl Altitude A600.4 Four-Channel Amplifier for Premium Sound Systems

Full Feature List

• High/Low Input Modes:High-level inputs are for connecting to speaker-level signals
• such as those from an OEM (factory) head unit.Low-level inputs are designed for connecting to line-level sources
• like aftermarket head units with RCA outputs. This versatility allows the A600.4 to work in a wide variety of audio systems.GTO™ Signal Sense:This feature detects the presence of an audio signal. It allows the amplifier to automatically turn on when an audio signal is detected
• eliminating the need for a remote turn-on lead. This is especially helpful in custom installations where the head unit doesn’t have a dedicated turn-on wire.Linkwitz-Riley Crossovers:The A600.4 uses Linkwitz-Riley crossovers
• a popular choice in audio systems. These crossovers ensure smooth frequency transitions and minimize distortion at the crossover points. The adjustable crossover allows you to control which frequencies are sent to your speakers or subwoofers for optimal performance.Start-Stop Compliant:The A600.4 is Start-Stop Compliant
• meaning it is designed to handle the power cycling that occurs in vehicles with start-stop systems (which automatically turn off the engine when stopped to save fuel). This ensures the amplifier works reliably even in cars with such systems.High Power Output in a Sleek Chassis:Despite delivering substantial power (75W per channel at 4 ohms
• 100W at 2 ohms)
• the A600.4 is housed in a compact and sleek chassis
• making it easy to install in tight spaces while maintaining a high level of performance.ParaBASS® Low Frequency Contouring:ParaBASS® allows you to adjust the low-frequency response in your system
• improving the bass response to suit your listening preferences. It's designed to enhance the bass without distorting the rest of the frequency range.Valet Mode Option:The Valet Mode is a security feature that restricts the power of the amplifier
• ensuring the audio system is limited (often used for situations where you might want to limit power for valet parking or other controlled scenarios). This helps protect your system from misuse or tampering.Optional Remote Level Control (ACR-1):The ACR-1 is a remote control that allows you to adjust the amplifier's output level remotely. This is especially useful when you need to make real-time adjustments to the volume without having to reach for the amp itself.EV Compliant up to 17V:The amplifier is EV (Electrical Vehicle) compliant
• meaning it can handle up to 17V input
• which is important for modern cars with higher voltage electrical systems. This ensures the amplifier can operate correctly even in vehicles with such systems.
