PRE 08

PRE 08 front

Introduction

PRE 08 is a high-performance pre-amplifier. That enables true premium sound quality with the use of J-Fet op-amp input stage. It features an advanced integrated feedback design only using the best components available. This technology allows ultra-low distortion across the audio band and superior audio quality.

The pre-amp is a straight forward design with two inputs and two outputs.

1 balanced XLR and 1 single ended RCA input with a 100 KOhm input impedance which is a perfect match for our line of DAC / RIAA. The output is 1 balanced XLR connectors and 1 single ended RCA with an output impedance of 75 Ohm. The volume control is based on Khozmo Acoustic type latter resitor attenuator.

Technology

The amplifier features a gain of 6dB which is a perfect match for our series of power amplifiers. This gain is also suitable for most modern power amplifiers.

The pre-amp has a switch on the front to select between single ended RCA or balanced XLR input. Due to the balanced design of the power stage, the single ended input are converted to a balanced signal at the input of the pre-amp.

The power supply is a CLC design as in most of our power supply’s. The use of a combination of capacitors and chokes ensures and extrime low noise supply. And prevent noise to radiate from the AMP (EMC). 

Backpanel input/output:

In use:

When turning on the pre-amplifier PRE08, using the power switch on the front panel. After a few seconds you will hear a click from the protection cercuit and the pre-amplifier will be ready to play. If the currently selected input has an active source connected, the pre-amplifier will start playing music. By turning the input selection switch, you can select any one of the inputs.

Connectivity (examples)

This page offers ‘suggested connectivity’. With so many products offerings a number of options, it is important to check the manual of the product you are connecting for the appropriate or optimum output connection and settings required to operate properly.

A perfect match for the pre-amplifier could be the Newontech DAC 08 Shown on the picture.
