DS-15A Dynamics TFSJFT Introduction The DS-15A is a versatile biamplified two-way vented loudspeaker system. Applications The DS-15A is an ideal system for solo musicians and keyboard based groups providing a complete sound reinforcement solution in a single package. PA applications such as recitals, conferences, receptions, or any event that requires a system that is easy to use and transport, will benefit from the DS15A. Description The DS-15A incorporates a 150 W amplifier for the low frequency transducer and a 50 W amplifier for the high frequency driver. Both are protected against overvoltage, undervoltage, overloads, including shorts to the supplies, thermal runaway, and instantaneous temperature peaks. The DS-15A has a built-in two channel mixer with a microphone input and a line input with independent level controls. A master volume control is also provided.

F As per IEC 268-5 (1989), re. a two octave band centred at 500 Hz. Half space anechoic. B Average of one-third octave band measures. C There is currently no standard method of averaging the beamwidth with frequency characteristics into a single meaningful figure, which impedes comparisons across manufacturers and very often even product lines. This, our own, criterion weighs the -6 dB coverage angles from one-octave bands according to their contribution to speech intelligibility. One and one-third octave bands comply to ANSI S1.11-1986. The low frequency section utilizes a high efficiency 15" low frequency speaker with 3" voice coil. The high frequency section makes use of a 1" exit compression driver with 2" titanium diaphragm, coupled to a constant directivity horn. Full use of high pressure injection moulding techniques has achieved a mineral loaded polypropylene cabinet of a very high density with minimum vibration. An integral handle facilitates carrying. A rugged steel grill protects the cone speaker. Two M8 flying points on the top and bottom of the enclosure allow flying. An integral 35 mm socket can be used for tripod mounting. DS-15A Frequency Response Figure 1 shows the frequency response at 1 m of a unit radiating to a half space anechoic environment and driven by a swept sine wave signal (-18dBm input). Distortion Figure 2 shows the Second Harmonic Distortion (grey) and Third Harmonic Distortion (dotted) curves for a unit driven at 10% of its nominal power handling rating. Beamwidth Figure 3 shows the -3, -6 and -10 dB horizontal (solid) and vertical (dashed) beamwidth with frequency curves. -6 dB ones are shown with thicker traces for clarity. Axial Directivity Q(R θ) and D i Figure 4 shows the above characteristics with frequency. Thin continuous and dashed lines show partial horizontal and vertical, respectively, characteristics. Polar Response Figure 5 shows the one octave band horizontal (solid) and vertical (dashed) polars for the indicated frequencies. Full scale is 50 dB, 5 dB per division. NOTES. 1.Frequency response: referred to 1 m; low end obtained through the use of near field techniques; one-third octave smoothed for correlation with human hearing. 2.Harmonic distortion components are not plotted beyond 20 kHz; near-field techniques used. 3.Directivity characteristics plotted with respect to frequency are the average within the one-third octave bands of center frequencies noted by the marks at the bottom of the graphs, but are joined up for display purposes. All other characteristics plotted vs. frequency use 1/24th octave resolution. Regions of less than 1 dB below goal level and sharp notches may be ignored when calculating beamwidths. 4.Directivity factor and index were computed from two degree resolution vertical and horizontal polars using sinusoidal weighting. 5.Polars were acquired by placing the unit on a computer controlled turntable inside our anechoic chamber. Measurement distance was 4 m. TE/054-00 D.A.S. Audio, S.A. C/. Islas Baleares, 24 - 46988 Fuente del Jarro - Valencia, SPAIN Tel. 96 134 0525 - Tel. Intl. +34 96 134 0860 - Fax. 96 134 0607 - Fax.
