Crown Macro-Tech 12000i เพาเวอร์แอมป์ เครื่องขยายเสียง Power Amplifier
This two-channel amplifier from Crown features onboard signal processing and a built-in network connection.
Product Description
The Crown Macro-Tech 12000i power amplifier is a solid-state two-channel model with a switch-mode universal power supply. The outputs are usable as dual or bridged-mono modes of operation. The bridged-mono mode bridges the outputs to provide increased output voltage. The Crown Macro-Tech i Series offers amazing power, light weight and ease of use for touring sound applications. The series includes onboard analog signal processing and a built-in network connection.
