Description

PRE-EQ4

THE PREQ4 IS AN “ALL IN ONE” CHANNEL STRIP THAT UPDATES THE PREQ3 MODULE AND FITS INTO THE STANDARD 500VPR RACK. UP TO 65 DB OF EXTREMELY CLEAN GAIN IS AVAILABLE TO HANDLE LOW OUTPUT RIBBON MICS AND/OR VERY QUIET SOUND RECORDINGS FOR FOLEY/FILM APPLICATIONS THAT REQUIRE HIGH GAIN WITH A LOW NOISE FLOOR.

THE PREQ4 FRONT PANEL STARTS WITH SEPARATE +48-VOLT PHANTOM POWER ON/OFF SWITCH AND PHASE REVERSE (POLARITY) SWITCHES. NEXT IS A SWITCHABLE -20 DB ATTENUATOR PAD THAT IS PLACED IN THE CIRCUIT JUST BEFORE THE INPUT TRANSFORMER TO AVOID SATURATION UNNECESSARILY WITH AN EXCESSIVELY, “HOT” MICROPHONE SIGNAL. ADJACENT TO THE PAD SWITCH IS THE HIGH PASS FILTER IN/OUT SWITCH. THE HIGH PASS FILTER HAS A VERY GENTLE SLOPE STARTING AT 160 HZ AND IS -3 DB DOWN AT 70 HZ. ALL FOUR OF THESE SWITCHES—THE 48-VOLT PHANTOM, PHASE REVERSE, -20 DB PAD AND HIGH PASS FILTER ALL HAVE LEDS TO CONFIRM THEIR STATUS.
