The Acoustasonic^TM Junior DSP is a portable, well built and easy-to-use combo amp designed for natural-sounding reproduction of electric-acoustic guitar and vocals. The onboard DSP effects and XLR output add extra versatility to an already-great formula. Its two 40-watt power sections drive two 8" drivers and a high-frequency tweeter; the instrument and microphone channels each contain individual EQ controls, phase switches for feedback reduction, effects select and effects level. Patented String Dynamics^TM control tames harsh treble notes, and feedback notch control solves most feedback problems. XLR mic input supplies phantom power, and the professional XLR line output with level control and ground lift allows perfect direct input to any mixer. DSP effects include reverb, delay, chorus, Vibratone and more; all optimized especially for acoustic performers. Other features include tilt-back legs, distinctive Brown/Wheat cosmetic treatment, and optional two-button footswitch that allows effects switching for each channel.
