Impulse® 12D

SPECIFICATIONS

INPUT CONNECTIONS: Input 1: One combo female XLR/ 1/4” phone jack providing balanced operation, with switch-selectable mic- or line-level sensitivity.

One 3-conductor balanced Euro-style jack connector

Input 2: One combo female XLR/ 1/4” phone jack providing balanced operation, with switch-selectable mic- or line-level sensitivity.

Two RCA phono-type jacks, which are buffered and mixed to monophonic for a summed signal. These are NOT a stereo input, as the Impulse® 12D is a single full-range sound source.

OUTPUT CONNECTIONS: One male XLR balanced output, one ¼” TRS balanced phone-type jack, one 3-conductor balanced Euro-style jack connector.

CABINET MATERIAL: Injection-molded polypropylene with internal ribbing and bracing, and with textured finish. Molded material is dark gray, as is the metal grille. Available in a white version as well.

MOUNTING: Subwoofer pole-mounting or speaker stand via molded-in pole mount, flying via Versamount™70+, and 4 rubber feet for floor or stage use.
