The Lanzar Heritage amplifier series, encompassing models HTG 214/224/234/244/254/264 (2-channel) and HTG 414/424/434 (4-channel), represents a range of American-crafted, high-performance car audio amplifiers designed for uncompromised musical service. These amplifiers incorporate the latest technology, including a DC to DC Switching Power Supply, which provides ample headroom for demanding audio peaks and dynamic ranges found in modern recordings.
Function Description:
The Lanzar Heritage amplifiers are designed to boost audio signals from a head unit or other signal source to power speakers in a car audio system. They offer versatile configuration options, including stereo, bridged mode, and tri-mode system applications, allowing users to tailor their sound system to specific needs, whether it's powering full-range speakers, subwoofers, or a combination in a tri-amp setup. The amplifiers feature built-in crossovers (high pass and low pass filters) to direct appropriate frequency ranges to different speakers, optimizing sound quality and protecting speakers from unwanted frequencies. A bass boost circuit with remote control provides enhanced low-frequency response.
