| Proposition 65 Notice | WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov |
| 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 | 5 Channel 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. |
| Bass Remote Included | Included on mono and 5 channel amplifiers. This allows the driver to make subtle changes to the bass response of the audio system from the seated listening position. |
| 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. |
