Cautions
The unit must be disconnected from the AC power source before any work is done on it. Refer all servicing to
qualified service personnel.
The back plate can become hot to the touch. Do not block or cover the fan or the exhaust louvers from ventila-
tion. There must be a minimum of 4” of space behind the fan. Do not allow the airflow to be become blocked
by objects such as curtains or drapes, thermal building insulation, etc. It is recommended that the rear of the
DM™115 not be placed in a closed space or a space that has no fresh, cool airflow.
Be sure to keep the microphone away from the front of the speaker after connecting it to the input, and while
setting the microphone level, or very loud feedback will occur! Damage to the system is likely if this occurs!
DO NOT connect the inputs of the DM™115 to the output of a power amplifier. The inputs are meant to be driv-
en from a line-level strength signal.
DO NOT remove the protective metal grille.
WARNING!
The DM™115 is very efficient and powerful! This sound system can permanently damage hearing!
Use extreme care setting the overall maximum loudness!
The apparent sound level of the DM™115 can be deceiving due to its clear, clean sound output. The lack of distor-
tion or obvious distress can make the sound level seem much lower than it actually is. This system is capable of
SPL in excess of 124 dB at 1 M from the speaker!
Connecting AC Power To The DM™115
The DM™115 comes with an 6-foot IEC connection AC power cord. If you are using an extension cord or power
strip with this powered speaker, make sure it is of good quality and of a sufficient current capacity to maintain
safety and maximize the power output capability of the DM™115. For maximum undistorted output, do not
connect any other device to the same extension cord that the DM™115 is connected to. Do not exceed the rated
current capacity of the extension cord with the sum total of all units connected to it.
When first plugging in the AC cord, make sure the power switch is in the Off position, and then turn it On only
once the power cord has been connected. Built-in muting will engage when the proper sequence of steps is tak-
en.
