The array of 128 high precision Thin Film Resistors closely resembles the discrete DAC used in the Cayin N7 DAP. \u003c\/p\u003e\n\u003cp\u003eDual amplifiers in parallel provide high output balanced power. The two amplifiers operate in parallel to provide 160mW @ 32 ohms in single-ended output and 400mW @ 32 ohms for the balanced output.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDiscrete Volume Control\u003c\/strong\u003e\u003cbr\u003eThe 1-Bit DAC design is very demanding of the input signal, and we recommend that you provide the maximum possible digital output volume from your mobile device to get the best signal from RU7. Cayin's specially developed low noise, low power consumption 100 step volume control offers precise control over a wide volume range to power a range of sensitive and harder to drive IEMs and headphones.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDual PCB Design Minimizes Interference\u003c\/strong\u003e\u003cbr\u003eRU7 uses a similar design to its predecessor, RU6, with two 6 layer PCB boards, separating digital and analog functions of the device. The two layers safeguard signal integrity and keep noise from the reference clock and DSP from bleeding into the amplification circuit.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eLow Power Consumption and High Compatibility\u003c\/strong\u003e\u003cbr\u003eDiscrete resistor network DACs have low power consumption compared to other integrated DAC designs, and minimize power drain from the mobile source. Combine the DAC design with a carefully designed amplification circuit and RU7 manages a low 100mA power drain.
