TS 400 – full-range vertical array cabinet
The TS 400 is a compact, powerful, and versatile loudspeaker system for mobile applications and fixed installations. It can be used either full-range or in active two-way systems for applications requiring subwoofers, where DYNACORD's PSD 215 and PSD 218 powered subwoofers make ideal companions. Vertical pattern control is essential if optimal sound quality and intelligibility are to be achieved in difficult acoustic environments. The TS 400 was designed to provide very even and smooth coverage over a very wide bandwidth by using spaced and filtered woofers as array elements.
The TS 400’s 2.5-way design places elements at both ends of the speaker column to maximize the distance between them, thereby ensuring that greater control over the low frequency range is retained. The MF- and HF-elements are placed in the middle of the column for a smooth transition between the different frequency areas and to achieve further control over the radiation pattern. Each group of elements has its own band-pass filter, to optimize the array’s performance and attenuation 90° off-axis whilst at the same time providing even coverage of the audience area front-to-rear, where the rate of attenuation is half that of an "unsteered” cluster. The directivity of the array is such as to ensure the SPL falls off by only 3 dB each time the distance doubles, compared with the 6 dB of a conventional two-way system.

PSD 215 / PSD 218 – powered subwoofers
The PSD 215 (1 x 15") and PSD 218 (1 x 18") are high-powered active subwoofers. Each is equipped with an integrated two-channel power amplifier and 24-bit one-into-three DSP controller boasting 48-bit double-precision internal resolution. These powered subwoofers therefore supply the ideal foundation for the uncomplicated construction of powered two-way systems, by eliminating the need for external controllers and power amplifiers.
The PSD 215 reconciles minimum size with maximum acoustic output. Largely responsible for this is a 15" Electro-Voice DVX3159 woofer specially developed for use in compact subwoofers. Its larger brother, the PSD 218, is equipped with an 18" Electro-Voice DVX3180 long-excursion chassis and delivers the performance demanded of 18" subwoofers in professional concert sound applications.

Both models are armed with a highly efficient dual-channel Class D amplifier with a nominal output of 2 x 1,000 watts RMS into 4 ohms for highest quality audio performance

PSE 215 / PSE 218 – passive subwoofers
The PSE 215 and PSE 218 are the passive versions of the PSD subs (i.e. the versions without integrated power amplifiers and DSP controllers) but they share the same dimensions, transducer configurations, and acoustic characteristics as their powered cousins. They therefore represent the ideal reinforcements for the active systems in larger venues.

Vertical array systems – system recommendations
Many high-performance systems can be created using the PSD 215 and PSD 218 powered subwoofers, the PSE 215 and PSE 218 passive extension subs, and the TS 400 vertical array cabinets. Optimized system presets are stored in the DSP engine of the PSD subwoofers.

DYNACORD's vertical array systems offer plug and play solutions that meet the requirements of a wide range of mobile applications and fixed installations, where their high sound pressure levels, outstanding audio quality, wide coverage patterns, and exemplary intelligibility – combined with what are in comparative terms extremely affordable prices – add up to make a powerful and convincing case.
