The PSD 218 is a high-performance powered subwoofer designed to simplify creating active 2-way systems. They use an integrated 2-channel digital power amplifier with internal 24-bit 1-in-3 DSP controller to optimize the sound quality and protect the subwoofer and full range system used with it. Examples for such systems are combinations of PSD subwoofers with full-range D-Lite, Corus and VariLine and the new TS 400 array cabinet.
The PSD 218 with an 18" Electro-Voice DVX3180 long-excursion woofer delivers the performance demanded of 18" subwoofers in professional concert sound applications. It produces extended low frequency response from a compact enclosure with plenty of punch.
Both models use a highly efficient Class D technology amplifier a microprocessor-controlled switched-mode power supply to deliver 2 x 1,000 watts RMS into 4 ohms for highest quality audio performance All DYNACORD power amplifiers are capable of withstanding the most extreme rigors of touring, they are protected against overheating, overload, short circuit, back EMF and open-circuit operation as well as HF or DC at the output. Thermal stability is assured by an extremely quiet continuously variable speed fan. The units are also equipped with intelligent thermal limiters that track voice coil operating temperature that allow maximum output without failure. being any noticeable reduction in loudness. PROTECT and LIMIT LEDs indicate the current operating status of the power amplifiers.
The integrated 24-bit digital controller with internal 48-bit double-precision resolution exhibits a 1-into-3 topology: SUB channel, TOP channel and an additional DSP Out.
