About the Peachtree Audio Shift

Dave Bar

Add more punch to your portable

The Peachtree Audio Shift plugs into your smartphone or portable music player's digital output to restore the punch and clarity your tunes deserve. This pocket-sized powerhouse combines a high-performance digital-to-analog converter (DAC), high-current headphone amplifier, and a robust rechargeable battery to deliver the power you need to pump out bigger, bolder sound — no matter where you are. Be prepared to hear your music with greater bass impact and low-frequency extension, along with more dynamic, detailed sound. And the same battery that powers the Shift can also charge an attached iPhone® or iPod® so the music can keep on coming for a long time.

Peachtree Audio's powerful-yet-portable Shift will make your music and your headphones come alive with sparkling clear sound.

Add more punch to your portable

The Peachtree Audio Shift plugs into your smartphone or portable music player's digital output to restore the punch and clarity your tunes deserve. This pocket-sized powerhouse combines a high-performance digital-to-analog converter (DAC), high-current headphone amplifier, and a robust rechargeable battery to deliver the power you need to pump out bigger, bolder sound — no matter where you are. Be prepared to hear your music with greater bass impact and low-frequency extension, along with more dynamic, detailed sound. And the same battery that powers the Shift can also charge an attached iPhone® or iPod® so the music can keep on coming for a long time.

A high-res audio champ

Along with all the sonic benefits the Shift provides for your compressed and CD-quality music files, it also has another trick up its sleeve — it decodes high-resolution PCM data streams of up to 32-bit/384kHz resolution, and DSD audio sources at 2.8MHz/5.6MHz, so you can enjoy better-than-CD audio quality. If you download high-res music files from HDtracks and other audiophile sources, the Shift makes sure you'll hear them in all their glory.

Outstanding sound from your PC, too

When you're not traveling, the Shift's asynchronous USB input and included adapter cable are ready to give your computer music a big boost. Just plug it into a USB port on your PC to bypass the sound card inside your computer — a noisy environment prone to producing poor sound quality. Your tunes will be output as fantastic-sounding analog audio signals ready for playback through your headphones, or even your home stereo or a pair of amplified desktop speakers using an optional stereo mini-to-mini or mini-to-RCA adapter.

Product Research

Features

Four Products In One: Peachtree Audio houses four products in one in the small and portable chassis of the Shift. It can be used as an external DAC, headphone amplifier, preamplifier, and USB charger.

  • It employs a 32-bit/384kHz asynchronous DAC for high resolution processing of PCM & DSD from computers, smartphones, and tablets.
  • Used as a headphone amplifier, it is capable of driving almost all high impedance and low efficiency headphones.
  • The Shift can even be used as a preamp for connection to a Hi-Fi system with a 103dB signal-to-noise ratio at its output.
  • Its internal rechargeable battery generates enough power for 7-8 hours of play time an doubles as a 5V/1A charger for your iOS device.

32-Bit/384kHz DAC: The Peachtree Shift employs a 32-bit/384kHz ESS SABRE32 DAC that will make 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. Shift uses 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 music files.

Compatible Audio Signals: The Peachtree Shift supports PCM (16-32bit/44.1-384kHz) & DSD (2.8/5.6MHz) audio signals.

  • PCM: 16, 24 and 32-bit @ 44.1, 48, 88.2, 96, 176.4, 192, 352.8 and 384kHz
  • DSD: 2.8 and 5.6 MHz

Dual USB Ports: The Peachtree Audio Shift is equipped with a USB (type-A) port for select Apple iOS devices and a miniUSB (type-B) port for Windows PC, Mac computers, and select Android smartphone/tablets. The Shift is designed to completely bypass the DAC on your smartphone, tablet, or computer and provide exceptional sound quality.

  • USB (type-A) Port: Use the Shift's USB (type-A) port to connect the following Apple iOS devices -  iPhone touch (5th gen), iPhone 5C/5S, iPhone 6/6+, and iPhone 6S/6S+. A Lightning-to-USB cable is included.
  • miniUSB (type-B) Port: Works Use the unit's miniUSB (type-B) port to connect your Apple Mac OS X 10.6.4 and later or Microsoft Windows XP and later with the included miniUSB-to-USB cable. The unit's miniUSB (type-B) port also works with Android devices that support USB OTG (On-The-Go) and USB Audio Class 2.0 (cable included).

Note: To playback music files from a Windows PC, you will need to download and install the driver from www.peachtreeaudio.com/support/usb-drivers.html.

Headphone Amp: The Peachtree Shift's headphone amplifier is an ultra-low-noise design that can power practically any headphone, from sensitive in-ear monitors to power-hungry over-the-ear models. The Shift features a 3.5mm headphone jack for its headphone amp. 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, the 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 internal components.

Preamp Mode: The Shift features a line-output mode switch so it can used as a USB DAC & preamp in your Hi-Fi system. Simply connect your personal computer to the Shift and let it provide the analog audio output to your system. You'll need a stereo minijack cable or a 3.5mm-to-stereo RCA adapter (both sold separately) to connect the Shift to an available line-level analog input on your Hi-Fi system.

High & Low Gain Switch: The Peachtree Audio 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). The Shift supports headphone output levels (@1kHz) of 230mW into 16Ω, 136mW into 32Ω, and 65mW into 300Ω.

Variable or Fixed Output: The 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.

Compact Aluminum Chassis: The Peachtree Shift's small, lightweight chassis is constructed of aluminum and finished with premium leather. The bottom of shift even includes rubber pads to add protection and stability when it is placed on a desk or table.

Rechargeable Battery: The Peachtree Shift features a high-capacity internal lithium-ion battery pack that can last up to 8 hours on a single charge. The unit's miniUSB port and included cable allow you to charge the battery from a 3rd party USB/AC adapter (sold separately) or a free USB port on your computer.  It takes approximately 4 hours to full charge the Shift's battery pack.

USB Charger: The Shift's built-in batter pack, USB ports, and included cables can also be used to "top-off" and charge your Apple iOS or Android device's battery in about 2 hours. Make sure the Shift's internal battery has a full charge and your Apple iOS or Android device's battery has more than a 50% charge when using the Shift as a USB charger.

You say:"plugs into your smartphone or portable music player's digital output." iPad, for instance, has no digital out. How then?

Just use USB adaptor cable...plug one end to your iPad and the other USB end into the Shift. I use $400 AKG headphones with my Shift and the sound is incredible.

Daniel You connect the Apple adapter that comes with the peachtree to the apple iPad . Then connect your headphones to the peachtree.Make sure both units are on charged and settings are adjusted to your satis faction. Go to music and play your music library, playlist etc as well as your radio, games movies youtube, Apple ,Pandora, Spotify,TuneIn etc. The side switches on the Peachtree are difficult to see clearly and it usually only takes one position out of place to prevent you from hearing anything.However once it is set properly, the same is absolutely amazing and will really enjoy them, Hope this was helpful .Enjoy your new portable DAC AMP Steven M Stoller MD

Hi Daniel, I bought the Peachtree Audio Shift in February this year. The connector on the IPad that the Peachtree would use would be the same connector (called the Lightning connector) that you use to charge the iPad. There is a cable that has the Lightning connector on one end that would go into the iPad and the other USB end would go into the Peachtree Audio Shift. Hope this helps. Best, Vijay
