Đặc điểm nổi bật của Đầu Ayre Acoustics CD Player CX-7
Thông số kỹ thuật
Đánh giá chi tiết
+ Multi-Stage Digital Filter: Sophisticated multi-stage digital filter system. First filter "upsamples" to 176.4kHz at 24 bits. Second filter "oversamples" to 1.4112MHz at 24 bits.
+ Dual Selectable Digital Filter Algorithms: User selectable choice of time-optimized or frequency-optimized filter algorithms.
+ Segmented Architecture DAC: Upper 6 bits are converted with a PCM architecture. Lower 18 bits are converted with a 5-level Sigma-Delta architecture operating at 11.2896MHz.
+ Differential Current-Output DAC: Sophisticated DAC allows use of dedicated differential zero-feedback current-to-voltage converters.
+ Zero-Feedback Analog Circuitry: Hallmark of Ayre designs said to ensure correct time-domain performance.
+ DC-Coupled Analog Circuitry: DC-coupled analog circuitry with no servos ensures perfect group-delay response at the lowest audio frequencies.
+ Balanced Audio Outputs: True differential balanced circuitry maximizes sonic performance. Single-ended outputs also included for legacy equipment.
+ Digital Audio Output: AES/EBU balanced digital output features transformer coupling for total ground isolation.
