    You only need the bias if it is an Electret mic
    The PR781 employs a Heil PR dynamic mic element . . . You do not need bias on

    Steve is correct.
    In fact, If you are using the 1/4-inch balanced connector, the Mic bias makes no difference, because no bias is applied to the 6600's 1/4-inch balanced connector, only to the 1/8-inch "pseudo-balanced" connector.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
