This full-range Class D amplifier is made for stronger speaker builds, louder mids and highs, and systems that need more headroom than a basic 4 channel can give. With four channels and serious stereo or bridged output, it makes a lot of sense for customers building aggressive daily systems, pro-audio-style speaker setups, or compact installs that still need real power. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"766\" data-end=\"1331\"\u003eOne of the best things about the HL 1200.4 is the flexibility. The page shows a 1 ohm version and a 2 ohm version, and this listing specifically includes that selectable output impedance option. On the 1 ohm version, it is rated at 4 x 300 watts RMS at 1 ohm and 4 x 200 watts RMS at 2 ohms at 12.6V, with even higher output at 14.4V. That means this amp can be used in a wide range of stronger speaker systems where you want more output per channel or more bridged power without giving up the simplicity of a 4 channel design. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"1333\" data-end=\"1841\"\u003eStetsom also keeps the tuning simple and practical. The HL 1200.4 includes fixed 90 Hz high-pass and low-pass crossovers, plus +12 dB bass boost on the low-pass side. The frequency response is listed at 10 Hz to 26 kHz, with greater than 90 dB signal-to-noise ratio and less than 0.3% THD. In real-world terms, that gives you a powerful full-range amp that still has the basic controls needed for speaker duty, mids and highs, or bridged applications in the right setup. \u003cspan

flexibility, and enough power to wake up a serious speaker system, the Stetsom HL 1200.4 is the kind of amp worth building around. \u003cspan class=\"\"
