Yamaha DXS18 DXS18/DXS15mkII/DXS12mkII Owners Manual - Page 2

Setup of Cardioid Mode Because directivity in the low frequency range is weak, the output sound from the subwoofer diffracts not only toward the audience but also to the stage in almost the same sound pressure. By using the Cardioid mode, bass to the audience is summed up and bass to the stage is canceled. This suppresses the bass volume on the stage, providing a greater allowance before howling, and provides more powerful bass for the audience. NOTE • Use the same model and input signal for the DXS. You can also use the units connected in daisy chain fashion with setting the OUTPUT jack to [THROUGH]. • To obtain the optimum Cardioid characteristics, locate the cabinet away from walls by more than 1.2 m. Two-unit, side-by-side placement Place the two DXS units facing in opposite directions. Set the CARDIOID switch of the DXS facing the audience to off, and that of the DXS facing the stage to on. Make sure that the other settings (LEVEL, POLARITY, X-OVER) of the units are set the same. From mixer From left DXS To right DXS To full-range *2 speaker *1 Off From mixer On *1 When a full-range speaker is connected subsequently. *2 When a full-range speaker is connected subsequently and the high pass filter in the full-range speaker is not used, set this to [HPF POST]. To full-range speaker Stage Audience To AC outlet Two-unit, vertically stacked placement You can also construct a system for Cardioid mode by vertically stacking two units. Set the CARDIOID switch of the DXS facing to the stage side to on. Make sure that the other settings (LEVEL, POLARITY, XOVER) of the units are set the same. CAUTION • When vertically stacking DXS units, make sure they are stable and not in danger of falling over. • Align the rubber feet of the upper DXS unit to the feet cups of the lower DXS. • When using vertically stacked DXS units, do not place any objects (such as full-range speakers or another DXS) on top of them or insert speaker poles.

Set the levels of the two DXS units facing the audience to the same. Set the level of the DXS unit facing to the stage approximately 6 dB greater than the DXS units facing the audience. From mixer From center DXS To center DXS Off Off From mixer Stage To AC outlet Audience From left DXS To right DXS On About Cardioid mode The distance between a speaker (A) facing to the audience sound source speaker and another speaker (B) facing to the stage is defined as d. A delay is applied to the sound from speaker B, equivalent to distance d. Waveform from A Stage side Reverse polarity delay Waveform from B d A B d Reverse polarity delay Audience side Sound is cancelled Sound is summed * This is the optimum state, in which the distance d is a quarter of the wavelength. Stage side Audience side The sound of each speaker is cancelled on the stage side and summed together on the audience side. The directional characteristics of this combination are represented in the polar pattern illustration at right. Since the form resembles a heart shape, it is called Cardioid mode. Directional characteristics Stage side Audience side PRECAUTIONS PLEASE READ CAREFULLY BEFORE PROCEEDING Please keep this manual in a safe place for future reference. WARNING Always follow the basic precautions listed below to avoid the possibility of serious injury or even death from electrical shock, short-circuiting, damages, fire or other hazards. These precautions include, but are not limited to, the following: Power supply/power cord • Do not place the power cord near heat sources such as heaters or radiators, and do not excessively bend or otherwise damage the cord, place heavy objects on it, or place it in a position where anyone could walk on, trip over, or roll anything over it. • Only use the voltage specified as correct for the device. The required voltage is printed on the name plate of the device. • Use only the supplied power cord/plug. If you intend to use the device in an area other than in the one you purchased, the included power cord may not be compatible. Please check with your Yamaha dealer. • Check the electric plug periodically and remove any dirt or dust which may have accumulated on it. • When setting up the device, make sure that the AC outlet you are using is easily accessible. If some trouble or malfunction occurs, immediately turn off the power switch and disconnect the plug from the outlet. Even when the power switch is turned off, as long as the power cord is not unplugged from the wall AC outlet, the device will not be disconnected from the power source. • Remove the electric plug from the outlet when the device is not to be used for extended periods of time, or during electrical storms. • Be sure to connect to an appropriate outlet with a protective grounding connection. Improper grounding can result in electrical shock, fire, or damage. Do not open • This device contains no user-serviceable parts.
