to make the product to monitor a digital signal endlessly precisely. This was the development concept of "DAHP-100". The know-how of the digital->analog conversion that it is developed by the development of many DA converters. Then, the know-how of the pure analog amplifier including HPA-20. The technology which Glasstone Ltd. accumulated so far is fully thrown, and it is the digital monitor headphones amplifier which made it go together. AK4397 made in Japan is adopted in the chip for the digital-to-analogue conversion. Until it reached details, it was optimized, and the digital-to-analogue conversion of the high precision which is not below when it is superior to a simple substance DA converter was realized . The circuit which has strong driving force is adopted with being a miniature in the amplifier circuit. (the combination of OP275+MOS-FET) Though bias electric current is being adjusted to the saving energy type which holds a fever, it has enough driving force, and headphones such as HD650 can take a drive easily, too. The digital volume that it was built in by a DAC chip is adopted for the level adjustment. An analog line output circuit can be used even if it is provided with it and (imbalance RCA) and DAC with the level adjustment function are taken, too. A sampling frequency copes with it to 192KHz, and it can monitor every digital audio signal. (linear PCM form)
