| 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 with hex screw terminals that allow for secure connections and is erosion resistant. |
| High Level Inputs |
See Auto-Sense Feature. |
| Operation Mode |
2 / 4 Channel |
| 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 SQ: Multi-channel amplifiers utilize the unique MB Quart Class SQ topology. Matched with Q-Stasis the sonic accuracy and clarity exceeds standard Class D amplifiers. |
| 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 |
Aluminum: Quickly dissipates heat to allow the amplifier to run lower impedance for longer duration. |
| Power Supply |
Rugged MOSFET Pulse Width Modulation power supply: Allows amplifier to produce 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 |

| 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. |
