SOUNDCRAFT 40 CH GB4 (YOM: ?) (S#: RW5693SM050724) AVERAGE FOR AGE (6-7)

FEATURES: SOUNDCRAFT GB4 40X8 MIXER FOR SALE. NO CASE. ALTHOUGH LARGELY CONVENTIONAL IN LAYOUT, THE GB4 DOES HAVE SOME UNIQUE MECHANICAL FEATURES. THE RUGGED STEEL CHASSIS HAS A SLOPING REAR CONNECTOR PANEL SO THAT IT IS EASIER TO CONFIGURE FROM THE FRONT OF THE DESK, WHILE THE INTEGRAL POWER SUPPLY HAS A LINK OPTION FOR AN EXTERNAL BACK-UP PSU.

FOUR MUTE GROUPS ALLOW SEVERAL CHANNELS TO BE MUTED SIMULTANEOUSLY, WHILE ANOTHER UNIQUE FACILITY IS THE LIMITER ON A SET OF DEDICATED RECORD OUTPUTS THAT MAKES IT EASIER TO CREATE A STEREO RECORDING OF THE MIX.

THE CONSOLE ALSO FEATURES AN OUTPUT MATRIX WITH SEVEN FEEDS TO FOUR OUTPUTS, BEING FED FROM THE GROUP BUSSES AND MAIN L, R AND C (MONO) OUTPUTS.

THE GB4 OFFERS A COMPREHENSIVE SET OF FUNCTIONS AND FACILITIES IN A SMALL AND COST-EFFECTIVE FOOTPRINT, AND DELIVERS THE HIGH PERFORMANCE AND RELIABILITY YOU WOULD EXPECT FROM A SOUNDCRAFT PRODUCT.
