MB Quart Premium Pro 4-Channel Amplifiers
The MB Quart Premium Pro 4-Channel Amplifiers series including the PA1-400.4, PA1-800.4, and PA1-2400.4 delivers high-performance, efficient audio amplification for cars, UTVs, and aftermarket sound systems. Each amplifier is engineered with a low-noise preamplifier circuit to minimize source noise and produce clean, detailed sound. Featuring tiffany-style nickel-plated RCA inputs and high-level inputs, these amps integrate seamlessly with OEM or aftermarket systems. Flexible four-channel operation allows for standard or bridged mono configurations while switched HPF/FULL/LPF crossovers provide precise control over signal routing. Built with full-range Class D topology and a PWM MOSFET power supply, the amplifiers deliver maximum output efficiently while minimizing heat. Durable extruded aluminum heat sinks with built-in fans on higher-power models maintain stable operation at low impedance, and heavy-duty nickel-plated terminals ensure secure, corrosion-resistant connections. Advanced three-stage LED protection circuitry monitors thermal, overload, DC, and speaker short conditions, protecting both the amplifier and connected components. Available in multiple power levels 400W, 800W, and 2400W, this series meets a wide range of audio performance needs.
Features
- Low Noise Preamplifier Circuit: Engineered pre-amplifier stage reduces incoming noise from source units and dramatically improves sound quality
- RCA Inputs: 2 pair tiffany style nickel-plated RCA jacks create an efficient connection that is corrosion-resistant
- High Level Inputs: Easily tie into OEM audio systems that do not offer RCA output to maximize after market amplifier power
- Operation Mode: Four channel operation: Flexible installation allows this amplifier to run in four channel or bridged mono mode
- Crossover Type: Switched HPF / FULL / LPF: Complete control of amplifier signal, essential when using two or more amplifiers
- Class / Topology: Full Range Class D: Highly efficient circuit topology which helps the amplifier develop a lot of power in a very small heatsink
- Output Device Technology: PWM MOSFET Power Supply: Stable power through the PC board with minimal heat generation
- Heat Sink: Extruded aluminum heat sink quickly dissipates heat to allow the amplifier to run lower impedance for longer duration
- Power Supply: MOSFET Pulse Width Modulation power supply that allows the amplifier to produce efficient power without taxing the electrical system
- Output Connections: Heavy duty output terminals allows for secure connection so electrical signal can pass into wiring and resist corrosion
- Connection Type: Nickel plated corrosion resistant connections
- LED System Protection Circuitry Diagnostics: Three-stage protection circuits: Monitor thermal, overload, DC, and speaker short protection with lighted indicators on the amplifier end panel
