 signals.

- Electronic Input Impedance (Nominal):

10 k ohms unbalanced

20 k ohms balanced line level

2.4 k ohms balanced mic level

- 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.
