The PSM300 inherits the uncompromising sound quality of the PSM1000/900 professional in-ear monitor systems, which have gained overwhelming support in the professional field. Audio is processed in 24-bit digital format for extremely high-resolution sound quality, and wireless transmission with no latency is achieved by employing FM analog transmission. Shure's proprietary ARC (Audio Reference Companding) is used for audio compression. The compression ratio is changed according to the audio level, resulting in high fidelity and clarity comparable to that of wired systems.
