Quad channel, precision analogue volume control equipped with the njw1195 controller, r202 offers 256 step, 0.5db volume control across four fully balanced channels'. '.strtoupper('i')t ensures ultra low distortion, accurate channel tracking, and smooth, high resolution volume adjustment'. '.strtoupper('m')atrix structured clean power supply design the headphone amplifier is powered by an lt8582 based high performance dual polarity boost supply, delivering ultra clean power with microvolt level ripple suppression through lc filtering, significantly enhancing dynamic load response'. '.strtoupper('t')he dac and op amps are powered by a matrix formed from tps61087 and tps61240 converters, followed by 7 ultra low noise ldos that independently power the digital, analogue, and clock sections'. '.strtoupper('t')his minimises noise density and lays a robust foundation for high fidelity audio output'. '.strtoupper('q')uad channel fully balanced headphone amplifier circuit built on a fully balanced dac architecture, the amplifier section uses four pieces opa1612 and two pieces of opa1662 op amps to form a true differential signal patch'. '.strtoupper('f')our ina1620 chips deliver quad channel balanced amplification with dual parallel design and four core balanced drive, ensuring precise full differential amplification of analogue signals for exceptional detail and dynamic response.
