The SBU is a battery operated USB Digital to Analog, and Digital to Digital converter,
headphone amp and line stage preamp all built into one compact chassis measuring
only 5" dia 5.5" long*. It has a USB input, SPDIF output via RCA jack and an AES/EBU
output via XLR jack. Its internal DAC supports up to 16-bit and 48kHz. We put a battery
pack in it so that those of you who are on the go can enjoy computer music using
headphones without looking for an ac outlet or having a separate battery pack. At
home, use the SBU to drive a pair of active speakers or a power amp with the computer
as source. A line level RCA input or a 1/8" mini jack is an available option so that
you can connect the CD player, MP3 player, iPod of your choice.
It comes with a standard power supply to charge the battery. It can also run on A/C
when the battery runs low. A full battery charge will run the SBU up to 20 hours.**
When powered via battery, the audio background is a lot "blacker." The result is
more low-level details and an improvement in dynamics and soundstage. Prepare to
be amazed at how good 16/44 digitally recorded music can sound through the SBU.
The ABS enclosure of the SBU is a major advantage if you want to take it on the road.
It can take serious physical handling that no other audiophile components can. Just
stick it in your bag, backpack or briefcase, hook up to your computer and headphones,
and you can enjoy your favorite music and movies. The SBU will also conserve power
from your laptop so it will last longer. At 20 hours running time, it will out last
any laptop in the market today.
