SPL Phonitor One D Headphone Monitoring Amplifier with 32-Bit DA Converter(並行輸入品)

• The Audiophile Headphone Amplifier with innovative Phonitor Matrix, 32-bit DA-converter and outstanding sound quality. For us the sound is always in the foreground. When it sounds good, we like to listen. To get such a sound, you need experience and technical finesse. We have incorporated both into the Series One.
• 32-Bit DA-Converter. The converter chip used is the Premium AK4490, a new generation of premium 32-bit DACs equipped with AKM’s Velvet Sound. This technology makes the finest details audible thanks to its low-distortion architecture. It supports sampling frequencies up to 768kHz PCM (16x CD resolution) and DSD (Direct Stream Digital) playback up to DSD4 or DSD256 (11.2 MHz) resolution. This qualifies the Phonitor One d for the currently highest resolution audio playback.
• Two Burr-Brown OPA 2134 SoundPlus operational amplifiers provide the pre-amplification. These are specially designed for audiophile circuits and are characterized by extremely low noise and minimal distortion of only 0.00008%. Thanks to a true FET stage, the OPA 2134 achieves a slew rate of 20V/?s, making it a high-speed operational amplifier. This has an immediate positive effect on the liveliness of the playback.
• The output stage of the headphone amplifier is designed as a push-pull amplifier in class AB mode. The bipolar transistors share the amplification of the positive and negative half-waves, which produces a higher gain and a higher output voltage than in Class A operation, where only one transistor amplifies both half-waves. The output stage transistors are thermally coupled and thus run particularly coherently, which contributes to a consistent and stable sound image.
• Two analog stereo inputs and one digital USB input can be connected to Phonitor One d. The computer, tablet or phone are preferably connected via USB. Other players such as a CD player, mixer, synthesizer or an analog tape machine / tape deck can be connected to the analog line inputs either balanced (TRS jacks) or unbalanced (RCA).
