Number One Active Subwoofer Module, 250W Max.

With the perfect equipment and workmanship for active subwoofer systems of the highest quality. The filters operate perfectly, for the subwoofer as well as the high-pass filter and a combination of systems of the highest quality is possible without any difficulties. Active subwoofer module, 250W

High-power active module with extensive equipment: 24dB subsonic filter, var. low-pass filter: 50-150Hz (18dB), semiparametric bass boost (var. 30-50Hz midrange with boost up to 6dB, continuously adjustable), continuously adjustable phase control 0-180° for uncompromising room adjustment and set-up adjustment, var. high-pass filter: 50-150Hz (12dB) for equalizing the bass frequencies of the satellite amplifier and the satellite speaker, ground lift switch of the studio technology against hum interference, and various protective circuits (short circuit, overheating and DC voltage overload). The great power can also perfectly drive enormous bass speakers with a diameter of up to 46cm, the sound and the workmanship are absolutely convincing. The high-quality active high-pass filter of the SAM-2 with versatile adjustments can conveniently be used as a bass relief of the main speakers and for optimising the sound. However, a regulated preamplifier output (Pre Out) is required for this. This kind of output is partly present at high-quality separable full amplifiers (Pre Out/Main In) or automatically provided by preamplifier/power amplifier combination or when using mixers.
