MB Quart QA1-1500.1D Q-Series 1500 watt mono-block subwoofer amplifier with a through-glass top design and red LED accent lighting. Bass remote included. Low Noise Preamplifier Circuit Q-Stasis Pre Amplifier Stage: The highly engineered Q-Stasis pre-amplifier stage reduces incoming noise from source units dramatically improving sound quality. RCA Inputs 1 pair of nickel-plated RCAs that allow for secure connections and is corrosion resistant. Operation Mode Mono operation: Designed to power 1 subwoofer or subwoofer system. Optimized input circuit to work with the QA1-900.6DSP for seamless integration. Crossover Type 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 amplifer provide high performance output. Output Device Technology MB Quart output devices, FLUID-FETS are painstakingly selected for their ability to efficiently produce power and provide high level of sound quality. Heat Sink Extruded aluminum heat sink that is machined to it final shape allows the amplifer to run lower impedance for longer duration. Power Supply Q-series amplifiers use a 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. Bass Remote Included Included: Wired Bass Remote allows adjustments to gain level to be made from the control mounted anywhere in the vehicle.
