Know before you buy
Yes, the dual-channel design is specifically built for this. You can blend two different sources—like a piezo pickup and a condenser mic—to get a more natural, full-bodied sound, especially for upright bass.
Yes, Channel B features 48V phantom power, which is necessary for running professional condenser microphones directly into the preamp.
The notch filter is a critical tool for live acoustic performance. It allows you to surgically target and cut the specific frequency causing feedback, letting you play at higher volumes without the unwanted howling or ringing common with acoustic instruments.
Absolutely. The balanced XLR output includes a built-in speaker simulator, which helps smooth out the harsh high-end frequencies often associated with direct-in acoustic signals, making it sound more like a miked-up cabinet.
The effects loop is flexible and can be set to either serial or parallel operation. This allows you to integrate your external pedals exactly how you need them, whether you want to process the entire signal or blend in effects like reverb or delay.
Yes, the preamp features high-impedance inputs (10 Mohms) designed to handle a wide range of pickup types, including passive, active, and piezo systems, ensuring you get the correct signal level and frequency response.
