| Description: |
The Chapter Couplet features a proprietary “ WMT” Class D amplifier Technology with new Zero Ripple, high frequency power supply. This groundbreaking technology uses four synchronous magnetic switching output stages, utilizing multiphase spread techniques, that give an effective switching frequency of 800Khz ( 4x Fsw ) and lower noise than any Linear PSU.
