Feedback amplifiers enjoy high stability and excellent power supply noise rejections. The low-noise low-distortion output faithfully reproduces even the most delicate nuances of the sound.
The power supply bypass capacitor can be minimal. The output pulse shape has been optimized to reduce electromagnetic interference, allowing a simple filter to suffice.
Every conceivable protection has been built in, allowing you to use the YDA174 with confidence.
Acoustic total-linear EQ is “total linear phase acoustic tuning technology” that compensates for the acoustic response of a specific chassis, not just in the frequency domain but also in the time domain.
This places movie dialogs in the center while positioning the sound effects not merely to left and right but also in front and behind,enveloping the listener.
Boosting the sub-harmonic of bass components and reconstructing mid and treble components lost in audio compressions adds perceptual depth.
The built-in voice cancellation effect allows casual karaoke enjoyment. Mic echo, reverb, and key control are possible.
・Overcurrent protection・Thermal protection・DC output protection
・Undervoltage lock out・Overvoltage protection・Pin matrix short protection
