DBX DBX F900A (YOM: ?) (S#: TBD) GOOD (7-8)

FEATURES: DBX F900A MAINFRAME WITH 8 MODULES. THE UNIT WAS TESTED TO ONLY POWER ON, WE ARE UNABLE TO TEST FURTHER. SOLD AS IS.

INCLUDES:

2 DBX902 DE-ESSER MODULES
2 DBX 903 COMPRESSOR/ LIMITER MODULES
4 DBX 904 GATE MODULE
THE 900 SERIES IS A MODULAR SIGNAL PROCESSING SYSTEM THAT ELIMINATES REDUNDANT PACKAGING, SAVES RACK SPACE AND PROVIDES EXCEPTIONAL FLEXIBILITY AND SERVICEABILITY. THE F900A MAINFRAME CAN ACCOMMODATE UP TO 9 MODULES. SOME OF THE MANY APPLICATIONS OF THE 900 SERIES PRODUCTS INCLUDE: MUSIC PRODUCTION AND SOUND REINFORCEMENT, TV AND RADIO PRODUCTION, MOBILE AND THEATRICAL PRODUCTION AND DISC MASTERING.

THE F900A IS THE FOUNDATION FOR CREATING A CUSTOMIZED “AUDIO TOOLBOX.” IT HOLDS UP TO 9 DBX 900 SERIES MODULES IN A 3U RACK SPACE. STANDARD BARRIER STRIPS PROVIDE ACCESS TO ALL INPUT AND OUTPUT CONNECTIONS. TO ENSURE RELIABILITY AND CONSISTENT PERFORMANCE UNDER THE MOST DEMANDING CONDITIONS, ALL INTERNAL CONNECTIONS TO MODULES ARE MADE VIA DOUBLE-SIDED, GOLD, BIFURCATED CONTACTS.

THE INDUSTRY STANDARD 902 DE-ESSER’S UNIQUE FEATURES MAKE IT POSSIBLE TO ACHIEVE THE DESIRED AMOUNT OF DE-ESSING, REGARDLESS OF VARIATIONS IN SIGNAL LEVEL. USING PATENTED DBX SIBILANCE DETECTION CIRCUITRY, THE 902 COMPARES THE RMS ENERGY OF SIGNALS ABOVE AND BELOW A SPECIFIED CROSSOVER POINT TO PRECISELY DETECT UNDESIRABLE SIBILANCE.

FEATURES OF THE 902:

GAIN REDUCTION ADJUSTABLE FROM 0 TO -20 DB
TWO GAIN REDUCTION MODES (BROADBAND AND HF ONLY)
NO NEED TO SET A THRESHOLD FOR DE-ESSING
TWO 902 MODULES MAY BE STRAPPED TOGETHER FOR STEREO OPERATION
HARDWIRE BYPASS SWITCH
EQUIVALENT TO THE STAND-ALONE DBX 160XT, THE 903’S FEATURES MAKE IT POSSIBLE TO ACHIEVE LARGE AMOUNTS OF COMPRESSION WITHOUT UNDESIRABLE SIDE EFFECTS. THE 903 USES PATENTED, TRUE RMS DETECTION TO PROVIDE AUDIBLY SUPERIOR COMPRESSION AND LIMITING. THE 903 ALSO USES DBX’S PATENTED OVEREASY® SOFT-KNEE THRESHOLD FOR A SMOOTH ONSET OF COMPRESSION. REAR PANEL ACCESS TO THE THE RMS DETECTOR ALLOWS THE COMPRESSOR TO BE TRIGGERED BY SIGNALS OTHER THAN THE AUDIO INPUT. NEGATIVE COMPRESSION RATIOS ARE ALSO AVAILABLE FOR SPECIAL EFFECTS.

FEATURES OF THE 903:

TWO OR MORE 903 MODULES MAY BE STRAPPED TOGETHER FOR STEREO OR MULTICHANNEL OPERATION
CONTINUOUSLY VARIABLE COMPRESSION RATIO FROM 1:1 THROUGH °:1 TO -1:1
INFINITY+™ (NEGATIVE) COMPRESSION
EXPANDED SCALE LED METERING
EXTERNAL DETECTOR INPUT
HARDWIRE BYPASS SWITCH
THE 904 IS AN EXPANDER GATE USING DBX’S OVEREASY® ACTION FOR A SMOOTH ONSET OF GATING. ATTENUATION LIMIT, ATTACK AND RELEASE RATES AND THRESHOLD ARE ALL ADJUSTABLE. THIS POPULAR GATE ALSO FEATURES PROGRAMMED LATCH MODE WHICH MUTES A CHANNEL UNTIL AN ABOVE THRESHOLD SIGNAL IS PRESENT. IT THEN LATCHES OPEN UNTIL RESET. THE 904 IS A VERY FAST VOLTAGE CONTROLLED BELOW THRESHOLD DOWNWARD EXPANDER. IT SENSES THE LEVEL OF AN INPUT OR KEYING SIGNAL AND DETERMINES WHETHER THE LEVEL IS BELOW THRESHOLD. IF IT IS, THE SIGNAL GETS ATTENUATED; IF NOT IT PASSES AT UNITY (0 DB) GAIN. THE AMOUNT OF SIGNAL ATTENUATION IS A FUNCTION OF ITS OWN LEVEL AND THE 904’S ATTENUATION, LIMIT, RATIO, AND THRESHOLD SETTINGS.

FEATURES OF THE 904:

TWO MODULES CAN BE STRAPPED TOGETHER FOR STEREO OPERATION
KEY INPUT FOR FREQUENCY-TAILORED GATING OR GATING OF ONE INSTRUMENT BY ANOTHER
ADJUSTABLE 0 TO 60 DB ATTENUATION
PROGRAMMED LATCH MODE
VARIABLE ATTACK AND RELEASE TIME
HARDWIRE BYPASS SWITCH
