设计理念

 

The A48-ECO is designed for a wide range of electro-acoustic instruments and supports both 48V phantom power and external DC power supply operation.
Featuring an internal voltage-boosting circuit, it delivers increased dynamic headroom and enhanced overload handling capability, allowing it to
accommodate extremely high peak input levels without distortion.Combined with a selectable -15 dB PAD attenuation, it is well suited for
high-output instruments.
The built-in ground lift function effectively eliminates hum and background noise caused by ground loops. The THRU output allows simultaneous
connection to a stage amplifier, while the balanced XLR output supports long-distance signal transmission with minimal loss.
With clean sound quality, ultra-low distortion, and wide frequency response,the A48-ECO is an ideal signal interface solution for acoustic guitars, basses,keyboards, and other instruments in professional live sound and recording applications.
