SHIFT is a USB Digital-to-Analog Converter (DAC) and headphone amplifier housed in a small and portable chassis roughly the size of a deck of playing cards. It is designed to completely bypass the headphone output on your smartphone, tablet or personal computer and provide exceptional sound quality - wherever you happen to be listening. The built-in battery pack provides up to eight hours of playback on a single charge so shift is a perfect travel companion - whether you are commuting to work on a train or taking a flight to visit friends and family. The built-in headphone amplifier powers everything from in-ear monitors to “difficult-to-drive” over the ear designs, and everything in between.
SHIFT is designed to be used in several listening situations. Its small size, light weight and real leather exterior lend itself to being a portable device. However, shift can also be connected directly to the USB port on a personal computer to drive your headphones or interface with your powered speakers in a desktop “computer audio” system. The sound quality improvement over using your computer’s headphone output is immediately noticeable! The bottom of shift even includes rubber pads to add protection and stability when it is placed on a desk or table. In addition, whenever shift is plugged into a USB port on your computer it is charging its internal battery pack so it will be ready to hit the road again whenever you are. Finally, shift features a line-output mode switch so it can used as a USB DAC in your Hi-Fi system. Simply connect your personal computer to the shift and let it provide the analog audio output to your system. We think you will be impressed by how great the shift sounds even when compared against much more expensive dedicated DACs!
The Peachtree SHIFT's headphone amplifier is an ultra-low-noise design that can power any headphone - from sensitive in-ear monitors to power-hungry over- the-ear models. With shift’s dedicated amplifier driving your headphones, you’ll be able to hear your music with superior transparency, imaging, detail and bass response. To help achieve this level of performance, each subsystem within shift’s multi-layer circuit board has been designed to operate with the lowest overall noise floor and distortion, in addition to extensive use of noise isolation techniques to minimize interaction between subsystems.
SHIFT’s 32-bit/384kHz ESS SABRE32 DAC will make all of your music sound great from lossy compressed files to lossless uncompressed files and everything else in-between. It is compatible with high-resolution music files all the way up to and including 32-bit/384kHz PCM and 5.6MHz Direct Stream Digital (aka double-rate DSD or DSD128)!shift is an asynchronous design featuring two internal clocks that minimize jitter from the source device at all sampling rates. shift also includes an extensive power supply circuit design with multiple stages of regulation and ESS’s patented Hyperstream Modulator and Minimum Phase filters to create natural, lifelike sound from all of your digital files.
SHIFT uses a microprocessor driven analog volume control that works with the volume buttons and sliders on your smartphone, tablet or personal computer. The variable output mode on shift is ideal when connected to headphones or powered speakers that don’t include their own volume control. The fixed output mode turns shift into a high-performance USB DAC for your Hi-Fi system. Simply connect a 3.5mm-to-stereo RCA adaptor from the shift’s output and feed any available line-level analog input.
SHIFT also includes a convenient output level switch to tailor the volume control for high-sensitivity headphones (most in-ear types) and low-efficiency headphones (most over/on-ear types).
shift features a high capacity internal lithium-ion battery pack so it can run for up to eight hours without draining the battery inside your connected device. In addition, shift can trickle charge a connected iOS device. Push the power switch to the "on and charging" setting (battery icon) and it will start to top up your connected iOS device. It could be the difference between a functioning phone or not at the end of a long trip!
Shift works with Android devices that support USB OTG (On-The-Go) and USB Audio Class 2.0. Not all devices are compatible.
