sOTM sDP-1000EX DAC/Preamplifier
sDP-1000EX from sOTM Audio is a high-end D/A converter and pre-amplifier with a USB audio function which supports DSD playback and has a battery power supply.
USB audio uses an asynchronous mode to connect the digital audio source device such as a PC. It can playback a 32 bit/192KHz PCM signal (maximum) and DSD signal. In addition, the sound quality from the input source can be improved by the specially designed high performance clock and 32 bit up-sampler circuit.
All audio circuit parts including the DAC and preamplifier volume control are fully balanced circuits. Not a single coupling capacitor is used in the audio signal path.
It has two battery packs installed, with one battery providing power whilst the other charges and switches between these functions automatically, so there is no additional work needed once it’s connected to a power supply for charging the battery. The sDP-1000EX will work continuously via battery power only.
