|The compact and lightweight DS4 is designed to amplify fiddles, ukuleles, mandolins, guitars, and any other acoustic instrument. It comes equipped with two custom made 8" coaxial speakers and 50 watts of power. The DS4 offers transparent tone regardless of what preamp system is being used. The DS4 is now available online and in retailers worldwide.
The master section of the DS4 includes a master volume control, a DSP effects controller to select from 16 different effects, and a three way toggle switch to allow the users to assign the effect to either channel or both. The rear panel comes complete with separate effects send and return jacks, an effects footswitch jack, a line out, a direct out, a RCA Tape/CD input and Tape/CD level controller.
Channel one includes a dual XLR and 1/4" input with phantom power, volume control, and bass and treble EQ controls. In addition to the features on channel one, channel two also features a notch filter to help control feedback during performances and a shape on/off toggle to cut the mid frequencies and increase the high and low frequencies.
