Features & Benefits
| Compatible Vehicle Fitment | Universal |
|---|---|
| Ultra-Low EMI Design | Shielded inductors are used in the BG series for increased sound quality that produces ultra-low EMI. |
| Mass-Loaded Heat Sink | The mass-loaded extruded aluminum heat sink results in better thermal management and output performance. |
| High-End Preamplifier Circuit | Accepts a wider range of input signals. |
| RCA Inputs | Nickel-plated RCA jacks create an efficient connection that are corrosion-resistant. |
| High Tolerance Output Device | BRUTUS BG amplifiers have MOSFETS designed for high output power and fast thermal dissipation through a SMT process that produces ultra-low EMI. |
| High Level Inputs | Easily tie into OEM audio systems that do not offer RCA output to maximize after-market amplifier power. |
| Operation Mode | 4 channel operation mode allows either stereo or mono bridged operation. |
| Clean Board Construction | 4-layer PCB design, using a thinner substrate, improves heat dissipation and enhances performance stability. |
| Class / Topology | BG amplifiers feature a Class-D chipset, making them more efficient and allowing for a wide frequency range. |
| Power Supply | Dual toroidal transformers paired with a high-frequency PWM drive results in higher power capacity compared to other transformer designs. This whole system is protected by a current overload limiter. |
| Delayed Turn-On Function | Ensures compatibility with a wide range of source units to eliminate any unwanted turn-on/off noises like hisses and pops. |
| Connection Type | Secure molded connection terminal for all Power, Ground and Speaker connections. Angled for ease of access while creating a clean wire mangement profile. |
| Stylized Badging | Switch between full constant blue LED lights, VU Meter mode, or full off. When switched to VU Meter mode, the amplifier’s logo reflects the audio level, making it useful for gain adjustment. |
| Triple Protection Circuits | Over/under voltage, short circuit, and thermal protection circuits give you peace of mind that your investment (audio system and vehicle) will be protected under nearly every circumstance. |
| Auto Turn-On | The DC SIGNAL SENSE switch will allow the amplifier to turn on when a signal is received on the high level inputs. An amplifier remote turn on wire is not needed to power on the amplifier. This feature can also be turned off. |
