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.
