Product description
- T'ang-ku-la Module The T'ang-ku-la Module uses a new three-stage feedback circuit. Further reducing noise and high frequency distortion, making the dynamic range rise to an unmatched 147dB new realm. The new technology greatly reduces heat generation, thus greatly improving reliability, extending electronic component life, and reducing thermal noise.
- Expandable inputs The A70 Pro has one set of balanced XLR and one set of single-ended RCA inputs. But with the Ext90 input expansion, you get a total of four balanced XLR and two single-ended RCA inputs.
- Relay volume control A70 Pro uses relays and resistor networks to form R2R volume control module, which provides precise volume control, long service life, and will not deviate even at low volume.
- A Headphone Amp, also a Preamp 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.
