The Ultrasound DS4 delivers 50 Watts of unmatched acoustic tone, in a lightweight combo package. The DS4 is a 50 watt, 2 x 8" acoustic guitar combo amp. Two instrument channels feature phantom-powered microphone inputs along with volume and active EQ for each channel. Other features include a studio quality DI, Effects Loop, and an additional Aux. Input for Tape/CD, drum machine, etc. To further enhance the DS4, the onboard 24-bit digital effects processor produces studio quality reverbs, delays, and chorus effects, which can be routed to either or both channels.

CHANNEL-1 is designed for both MIC level (XLR) or Instrument level (1/4") signals. The 1/4" TRS (Tip/Ring/Sleeve) input jack is suited for equipment such as high impedance microphones, keyboards, and drum machines. It accepts both balanced and unbalanced inputs. (Channel-1 is designed as a generic "flat response" channel that is suitable for any acoustic instrument level or microphone signal.)

CHANNEL-2 is designed primarily for acoustic guitar and is equipped with an 18dB cut NOTCH FILTER that is used to control resonant feedback and a mid-cut SHAPE CIRCUIT to eliminate mid range “quack” from your guitar or pickup.
