Designed to act as a pseudo-extension cord for crowded audio mixers, laptops, instruments, radios, or any other active audio source with limited I/O, the Laptop Sound Port 3 from Dsan is a passive, multi-input direct box that converts low-level or unbalanced signals to balanced mic-level signals. With the built-in 6' long 3.5mm TRS pigtail cable, you can connect directly to active audio sources, or use the onboard stereo 1/4" TRS, 3.5mm TRS, and RCA loop out inputs to expand the I/O of any device.
The LSP-3 includes a hefty, dedicated volume knob for controlling the overall levels of your entire signal chain. A switch provides selection of active channels (L, R, or L+R), while a separate switch activates a ground lift for eliminating unwanted hum from grounding loops. Two mono balanced XLR outputs send your signals out as duplicated or summed mic-level signals for input into mixers, interfaces, and live sound systems. The LSP-3 includes a zipper soft storage case capable of accommodating the long pigtail cable.
