Yamaha DSR Series Active Loudspeakers

Review by Stacy Zemon

The Yamaha DSR series comes in several configurations: a choice of three two-way, full-range cabinets: the DSR112, DSR115, and DSR215; and an optional subwoofer, the DSR118W.

Being powered speakers (with parallel inputs), you can devise any configuration, but my review focuses on the DSR115 full range cabs and the DSR118W subwoofers.

While the cabinets are not light weight, neither are they ship anchors, owing to their well-balanced design and ergonomically-placed handles.

Hookup and operation are straightforward. On the DSR115, you plug the XLR or 1/4″ cable into the cab’s input. An XLR Thru jack is also included for daisy-chaining speakers together from a single signal source.

The back panel functions are simple to operate. There’s a single-level control with a center detent to put you right at a calibrated +4dBu line level. You can also switch in a handy boost circuit if you’re plugging a mic directly into the cab.

Three additional functions, each with its own dedicated switch, perform the following: 1) disable the front LED; 2) activate the high-pass filter (for eliminating stage rumble and wind noise); and 3) activate D-Contour—Yamaha’s multiband dynamic processor that monitors and adjusts the output levels. The power outlet and heavy-duty rocker on/off switch are safely located on another part of the cab, further down.

The DSR118W’s hookup scheme is only slightly different. There’s no 1/4″ input, but there are left and right XLR In and Thru jacks. The Front LED Disable switch and Level control are present, along with a Normal/Inverted Polarity switch (that you’ll sometimes see referred to erroneously as a “phase” switch on other gear).
