MB Quart Formula series compact four channel car audio amplifier featuring innovative sound quality and power technology. The FA2-400.4 is a 400 watt bridgeable car audio amplifier. Formula amplifiers feature DC Sensing to allow any amplifier to be easy integrated into an OEM system by simply adapting a RCA cable from the source unit.
| Low Noise Preamplifier Circuit |
Q-Stasis Pre Amplifier Stage: Maximum low voltage signal from the source unit comes into the amplifier circuit with minimal distortion. |
|---|---|
| RCA Inputs |
Nickel Plated: High temperature impact resistant nickel-plated RCA inputs that allow for secure connections and is erosion resistant. |
| High Level Inputs |
DC SIGNAL SENSE: The DC SIGNAL SENSE switch will allow the amp to turn on when a signal is received on the RCA inputs, so an amplifier remote turn on wire is not needed to turn on the amplifier. This feature can also be turned off. |
| Operation Mode |
4 channel operation mode allows either stereo or mono bridged operation. |
| Crossover Type |
Variable electronic crossovers allow for complete control of the sound. |
| Electronic Equalizer |
Control of amplifier output with on-board electronic crossover to tailor specific frequencies to speakers and subwoofers. Check specifications for specific frequencies for this amplifier. |
| Class / Topology |
Class Q1 (Class D): MB Quart’s Class Q1 offers the efficiency of today’s D-Class with increased engineering to focus on sound quality from the power supply through the output devices, the FLUID-FETS. |
| Output Device Technology |
FLUID-FETS: MB Quart output devices, FLUID-FETS are painstakingly selected for their ability to efficiently produce power and mimic the sound quality of the highest end home amplifiers. |
| Heat Sink |
Heavy duty heat-sink efficiently moves heat from the MOSFET where it can be cooled. |
| Power Supply |
Rugged MOSFET Pulse Width Modulation power supply: Allows amplifier to product efficient power without taxing the vehicle electrical system. |
| Output Connections |
Heavy duty connections allow for secure electrical signal to pass into wiring and resist erosion which will add longevity to the amplifier. |
| Connection Type |
Secure connection for all power, ground and speaker connections. |
| LED System Protection Circuitry Diagnostics |
Monitor overload and speaker short protection with illuminated indicators on the amplifier end panel. |
| Auto Turn-On |
DC SIGNAL SENSE: The DC SIGNAL SENSE switch will allow the amp to turn on when a signal is received on the RCA inputs, so an amplifier remote turn on wire is not needed to turn on the amplifier. This feature can also be turned off. |
