HME DM5 Quick Reference Installation Manual

These instructions are for mounting the DM5 Microphone in a speaker post
or menu board. The installation will take approximately 20 minutes.

Tools/Equipment Required

• General tools: screwdrivers, cutters, pliers, wire strippers, etc.
• Soldering iron and solder
• Crimp caps or shrink tubing with heat gun
• Serrated knife
• Audio Cable and Acoustic Foam (both not included)

INSTALLATION PROCEDURE

CAUTION: Remove power from the audio system before beginning.
Typical DM5 Microphone installation involves placement of the microphone
in its molded foam enclosure and mounting it inside the upper compartment of the speaker post, con-
necting it to the microphone/speaker cable wires from the drive-thru audio system, and filling the empty
space behind the unit with acoustic foam (not provided). If the DM5 is mounted in a small area, its mold-
ed foam enclosure may need to be compressed in order to close the compartment. Follow these instruc-
tions to install the DM5 in a typical speaker post. Installation in the microphone compartment of a menu
board is similar to installation in a speaker post.
• Open the speaker post and remove any existing equipment,
foam or debris. If there is an existing microphone, dis-
connect it from the audio system's microphone cable and
remove it.
• Remove the small portion of the provided foam microphone
enclosure, resulting in the two pieces of foam shown in
Figure 2.
• Insert the DM5 Microphone cable through the hole in the
foam enclosure, and place the microphone into the hole as
shown in Figure 2.
• Insert the removed piece of foam back into the hole in the
foam enclosure, as shown in Figure 2, to fit snugly against
the back of the microphone.
• Using a serrated knife, trim the foam enclosure, so it is ¼
to ½ inch larger than the upper speaker post compartment, vertically and horizontally, for a com-
pressed fit. Retain the foam pieces to add to acoustic foam to fill the speaker post compartment, if
needed.
• Place the foam windscreen in front of the microphone, positioning it so it will cover the inside of the
speaker grill, as shown in Figure 3.
• Place the microphone, in its foam enclosure, into the upper compartment of the speaker post, so the
front of the foam windscreen is flush against the metal, centered on the grill, as shown in Figure 3.
• Splice the audio system's microphone cable wires (new or existing) to the wires of the cable extending
from the back of the DM5, according to the audio system wiring diagram. Solder the connection,
and then cover the splice with shrink tubing or crimp caps.
