, After successfully saving, press C1 / C2to use the corresponding settings. Low noise is a perseverance Actual noise level of A70 Pro <0. 2uvrms @ G = L, <0. 8uvrms @ G = H Excellent performance at both high and low gain At an output voltage of 50mv, the A70 Pro achieves a far superior dynamic range of 106 3db. A Headphone Amp, also a Pr amp The A70 Pro drives headphones well, and it can also be used as a preamp. It has the same high performance as the headphone amp mode, with an RCA output impedance of only 50 and an XLR output impedance of only 100, allowing it to be used with a wide range of input impedance for various power amplifiers.
In addition, a full-featured remote control makes operation even easier. 1 2V Trigger A70 Pro has 12V Trigger input and output interfacewhich supports being triggered by other devices to switch on and off, and also supports actively triggering other devices to switch on and off synchronous.
