Installation

Floor monitor

When using the DYNACORD AXM 12A as a floor monitor, make sure to:

• Place the speaker on a level, stable surface that is solid and secure.

• Route cables so that performers, production crew and audience members will not trip
over the cables. Secure cables with wire ties or tape whenever possible.

Tripod

The AXM 12A loudspeaker includes a 35 mm (1-3/8 in) stand mount to allow mounting on
tripod stands or above a subwoofer. Make sure to:

• Check the specifications of the speaker stand to be certain it is capable of supporting the
weight of the speaker.

• Check that the speaker stand is placed on a flat, stable surface and be sure to fully
extend the legs of the stand. Do not try to make the stand “taller” and compromise its
structural integrity.

• Route cables and position the stand so that performers, production crew and audience
members will not trip over the stand or cables and pull the speaker system over. Secure
cables with wire ties or tape whenever possible.

• Do not attempt to suspend more than one speaker on a stand designed for a single
speaker.

• Unless you are confident that you can safely handle lifting the weight of the speaker onto
the stand, ask another person to help you place it.

Connection

Mains input (MAINS IN)

The device receives its power supply via the MAINS IN socket. Only the provided power cord
may be used. Connect the device only to a mains network, which corresponds to the
requirements indicated on the type plate.
The power switch allows for switching the power ON or OFF. The LCD screen lights up when
the power is turned ON.

Audio inputs

Caution!

High sound level

Before making any connections or disconnections, make sure to set the corresponding level

controls in the fully counterclockwise position -∞.

5.2.1

Microphone/line input

Electronically balanced INPUT 1/2 MIC/LINE for the connection of a line level signal source
(such as mixer etc.) or a microphone. Phantom power can be enabled (see menu item
Phantom 1 or 2 in section Menu, page 12) if a condenser microphone is being used.
Establishing a connection is possible via TRS or XLR-type plugs. Whenever possible, balanced
signal feed is always preferable to guard against potential noise or HF-interference.

Aux input

Stereo unbalanced RCA type INPUT 3 AUX IN for connecting sources such as CD players or
MP3 players. See menu item MIX OUT link in section Menu, page 12 how this input can be
used.

Audio outputs

Thru output

5.3.2

The THRU output socket is connected in parallel to INPUT 1, it is used for “carrying through”
the pre-fader input signal to additional powered loudspeaker or subwoofer.

Mix output

The post-fader audio signals of INPUT 1, INPUT 2 and INPUT 3 are mixed and passed to MIX
OUT. The ratio of the input signals changes when the level controls INPUT 1, 2 or 3 are
adjusted. This feature allows the loudspeaker to act as a basic three-channel mixer that can
send the mix to another loudspeaker via the MIX OUT socket.
This output is laid out in GND-SENSING technology, a special pin assignment of the output
socket, offering all advantages of the balanced signal transmission, but lets you also connect
monaural plugs without a problem.
