INTRODUCTION: Thanks for purchasing Applied Research and Technology’s DJPRE II™, a high quality Phono preamp designed for your home and studio. It acts as an interface between your turntable and your audio recording system. The analog input capacitance can be switched between 100pf and 200pf to optimize your phono cartridge response. A switchable low cut filter removes turntable rumble while leaving the audio pristine.
• • Heavy duty extruded chassis Designed and developed in the USA
The Facts About Turntable Preamps Phonograph Records Have Three Basic Problems 1. It is physically impossible to press them with ridges that allow low frequencies to come out at the same reproduction level as mid and high frequencies. Bass compensation is therefore needed during playback. 2. Records produce a certain amount of hiss which is covered up in post-production by boosting the gain of the high frequencies before pressing. Counter-EQing during playback compensates for this. 3.
INSTALLATION and OPERATION: 1. Connect the AC adapter to the Power Input on the DJPRE II and plug the other end into an AC power outlet. If you are using the unit with a home stereo, see if your receiver or other component has a "switched" output, which will power the unit on and off with the rest of your system. 2. Connect the turntable leads to the Input connectors on the DJPRE II. 3. If the turntable has a separate ground wire, attach it to the Ground terminal on the DJPRE II to reduce hum. 4.
