INTRODUCTION

Thank you for choosing Peachtree Audio! Please take the time to read this 

manual and visit www.peachtreeaudio.com to register your product. Your 

information will not be shared with anyone and we will only contact you with 

news  that  is  specifically  relevant  to  your  purchase!  If  you  have  additional 

questions or feedback please contact your reseller or Peachtree Audio directly.

The preDAC (short for preamplifier/Digital-to-Analog Converter) is designed 

to integrate a wide range of audio input sources including; phonograph, 

personal computer, Apple iOS device, streamer and other audio devices and 

drive a separate power amplifier like the Peachtree Audio amp500.

All Peachtree Audio products share a form follows function design philosophy 

with an emphasis on ease of use and sound quality. Other than the on/

standby button, the entire user interface is built around the concept of simply 

pressing a button to determine what you are listening to and turning a knob 

to determine how loud you are listening to it. Thats it! Inside, the preDAC is 

designed to provide the purest audio path between the input and the outputs. 

Analog inputs remain analog all of the way through the product to ensure that 

the original input signal is not altered or degraded in any significant way. All 

digital inputs are converted to analog internally utilizing ultra-premium quality 

digital-to-analog converters (DACs) so that they benefit from the best sound 

quality available today!

Each function of the preDAC has been specifically designed to provide the 

highest level of musicality and the lowest amount of noise regardless of the input 

source or the listening method. Each individual function provides a listening 

experience that compares favorably with dedicated audio components that 

perform a single function and often cost more than the entire preDAC!

The preDAC includes eight (four for the left channel and 4 for the right 

channel) 32-bit/384kHz DACs that are capable of accepting all of the major 

file formats currently available today including PCM up to 32-bit/384kHz and 

DSD up to 5.6MHz. This includes compressed audio, uncompressed audio, 

high-resolution audio and ultra-high resolution audio. Built around the DACs is 

an extensive, multi-point, regulated power supply that keeps them operating 

optimally and faithful to the input signal, providing the most natural sounding 

and musical experience available today. By utilizing four DACs per channel, 

the noise  floor is pushed  further away from the music allowing  it to come 

through with an unprecedented level of transparency.

The preDAC has very flexible input and configuration capability. It accepts 

input  from  a  computer,  digital  audio  devices,  analog  audio  devices,  iOS 

devices and even has a built-in phono preamplifier for connecting a turntable. 

The two analog inputs are user-configurable as: 2 standard analog inputs, a 

Home Theater Bypass (HTB) input + an analog input, an analog input + a
