R-09HR Ver.3.0

WAVE/MP3 Recorder

Q.What is IARC (Isolated Adaptive Recording Circuit)?

A.The quality of a recording is determined by the recorder's internal analog circuit. In order to deliver consistently high-quality sound, the R-09HR uses a high-fidelity analog IARC (isolated adaptive recording circuit), the design of which incorporates Roland know-how to the fullest possible extent. The IARC optimizes the input audio signals for the input level of the unit's internal A/D converter, and also reduces the residual noise level and delivers an expansive dynamic range by splitting the power source for the analog circuit and the digital circuit.
