| 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 |
Prewired to PC Board for additional protection. Leave connector cover closed on RCA jacks that are not used. |
| 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 D: Highly efficient circuit topology which helps the amplifier develop a lot of power in a compact heatsink. |
| Output Device Technology |
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 |
Robust premium grade MOSFET Pulse Width Modulation power supply allows the amplifier to produce efficient power without taxing the electrical system. |
| Output Connections |
Waterproof connectors designed to provide a secure moisture-resistant connection, ensuring reliable signal transmission and preventing corrosion or damage in environments exposed to water or humidity. |
| Connection Type |
Waterproof connectors designed to provide a secure moisture-resistant connection, ensuring reliable signal transmission and preventing corrosion or damage in environments exposed to water or humidity. |
