1 Introduction
The DYNACORD powered A-Line series includes three
models: a 12-inch, two-way full-range; a 15-inch, two-way
full-range; and a perfectly matching 18-inch subwoofer. All
three models feature solid 15-mm plywood enclosures that
combine durability with low weight. A high-quality black
paint finish and steel grille offer road-ready ruggedness
and a professional appearance. The full-range models are
equipped with a 12-inch EVS-12K woofer (A 112A), a 15-
inch EVS-15K (A 115A) and provide an 1.5” titanium dia-
phragm compression driver radiating into a 90 x 50-degree
(H x V) high-frequency waveguide. Both of the cabinets
provide an asymmetrical footprint with a 60-degree moni-
tor angle allowing for alternative use as a powered floor
monitor.
The onboard power modules of A 112A and A 115A com-
bine lightweight Class-D dual-channel power amplifiers
(biamping) with a total of 500 W dynamic peak power,
along with the digital signal processing for crossover (24
dB/octave slope), EQ and advanced digital speaker protec-
tion. The linearization of transfer function in both cabinets
is provided by state-of-the-art FIR filter technology.
The operating and connector panels are designed for intu-
itive operation and versatile connectivity. The 2-channel
mixer section offers a XLR/TRS combo connector Line 1,
stereo RCA sockets and a level control in the Input 1 chan-
nel, and a second XLR/TRS combo connector Line 2 which
is switchable for microphone or line sensitivity in channel
Input 2. For daisy-chaining to other devices, there is a XLR
link output available which can be set to provide either the
Line 1 or the mix signal.
In the Master section we find the overall Volume control,
along with a switch for selecting the dedicated EQ setting
for either Main or Monitor operation. A second switch ac-
tivates a high-pass filter when using the full-range cabinets
in combination with a powered subwoofer (A 118A).
The powered subwoofer A 118A features a similar power
module with 400 W peak power, Master Volume control, a
phase-inversion switch, a XLR/TRS combo input connec-
tor, and a XLR link output socket.
Setting up a small - yet very powerful - system turns out to
be a piece of cake when combining with DYNACORD CMS
mixing consoles (e.g. CMS 600-3). They are the perfect fit
and offer a broad range of advanced features in concert
sound quality.
1.1 Scope of Delivery, Unpacking and
Inspection

1 MAINS SWITCH (POWER)
Mains switch for switching the unit’s pow-
er on or off. The switch lights after turning
the power on. If the switch does not light
when powered on with the mains cord
correctly connected and mains voltage
present, please contact your local dealer.
2 M
AINS CONNECTOR (MAINS IN)
The device receives its power sup-
ply via the MAINS IN connector.
Only the provided power cord may
be used. Connect the device only
to a mains network, which corre-
sponds to the requirements indi-
cated on the type plate.
3 I
NPUT CONNECTOR FOR AUDIO SIGNAL (LINE 1/INPUT)
Electronically balanced input for the con-
nection of a line level signal source, such as
mixer, signal processor, etc. 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.
4 O
UTPUT CONNECTOR FOR AUDIO SIGNAL (LINK OUTPUT)
This output socket is for the connection of
an additional powered loudspeaker or sub-
woofer. The output signal is electronically
balanced with a maximum level of +18 dBu.
Output impedance is 150 ohms.
For the A 112A or A 115A, the output signal
is based on the selection made at the signal
source selection switch SELECT.
5 L
IMIT INDICATOR (LIMIT)
The LIMIT indicator signals the device is operating at
the internal power amp’s limit. Frequent blinking of
the LED is acceptable, since the incorporated DSP
clip limiter prevents distortion. Continuous lighting indi-
cates that you have to be aware of degradation in the out-
putted sound. In that case, the input level has to be
reduced. The LIMIT LED also lights if the output level is re-
duced because of high amplifier temperature.
6 V
OLUME LEVEL CONTROL (VOLUME)
Level control for adjusting the volume of the
loudspeaker. The level control affects the
power amp’s overall amplification. VOLUME
control does not affect the level of the LINK
OUTPUT connector.
7 P
OLARITY SWITCH (PHASE)
Select 0° if the signal polarity should not be
inverted. Select 180° to change the signal
polarity by 180°.
8 I
NPUT CONNECTOR FOR AUDIO SIGNAL (INPUT 2) WITH SENSI-
TIVY SELECTION SWITCH (MIC/LINE 2)
Electronically balanced input for the
connection of a line level signal
source (such as mixer, signal proces-
sor, etc.) or a dynamic microphone.
Establishing a connection is possible
via TRS or XLR-type plugs. Whenever
possible, balanced signal feed is al-
ways preferable to guard against potential noise or HF-in-
terference.
MIC/LINE 2 switch
Use the MIC/LINE 2 switch for switching between micro-
phone (+40 dB) or line (0 dB) input sensitivity. When de-
pressed, it activates a microphone preamp for use with
dynamic microphones. A pen or paperclip is needed to de-
press the switch to MIC mode.
CAUTION: Do not plug a line level signal into INPUT 2
when MIC/LINE 2 is in the MIC position.
HINT: There is no phantom power available at the
INPUT 2 connector, so powering a condenser
microphone is not possible.
9 AUX
CONNECTOR FOR AUDIO SIGNAL (AUX L/R)
Stereo unbalanced RCA inputs AUX L/R
for connecting sources such as CD play-
ers or MP3 players. Both RCA inputs are
summed and can be controlled with IN-
PUT 1 LEVEL. The inputs can be used simultaneously with
the XLR/TRS LINE 1 connector.
10 S
IGNAL SOURCE SELECTION SWITCH (SELECT)
Use the SELECT switch for selecting the out-
put signal of the LINK OUTPUT connector.
LINE 1
LINE 1 allows the pre-fader signal from LINE 1 input to
pass to LINK OUTPUT (see illustration 2-1). The LINK OUT-
PUT signal level is not affected by the setting of the
INPUT 1 LEVEL control. The signal from AUX L/R is not
passed to LINK OUTPUT in this switch position.
Illustration 2-1: Signal flow LINE 1
A 112A | A 115A | A 118A

MIX
The post-fader audio signals of INPUT 1 (LINE 1 and AUX)
and INPUT 2 are mixed and passed to LINK OUTPUT (see
illustration 2-2). The ratio of the input signals changes
when the level controls INPUT 1 and INPUT 2 are turned.
MIX allows the loudspeaker to act as a basic two-channel
mixer that can send the mix to another loudspeaker via the
LINK OUTPUT connector.
11 S
PEAKER MODE SELECTION SWITCH (MAIN/MONITOR)
Select MONITOR to activate optimized sig-
nal processing for floor monitoring appli-
cations. MAIN works best for music
playback and applications that require enhanced bass and
treble.
12 S
ELECTION SWITCH FOR MAIN MODE (FULL RANGE/LO-
CUT)
If the speaker is used as a full-range sys-
tem, select FULL RANGE. If a subwoofer
without a low-cut signal output is used,
i.e. the identical audio signal is used for
the A 112A/A 115A and the subwoofer,
select LO-CUT for activating the internal 100 Hz low-cut fil-
ter of the A 112A/A 115A. If the A 112A/A 115A is connect-
ed to the HI-OUT output of a subwoofer with integrated
low-cut filter, select FULL RANGE to avoid having the two
low-cut filters of the subwoofer and A 112A/A 115A in se-
ries.
The setting LO-CUT can also be used for delay applica-
tions, when a high bass level is not necessary.
13 INPUT 1
LEVEL CONTROL (LEVEL)
Level control for adjusting the amplification
of the signal at the LINE 1 and AUX L/R input.
14 INPUT 2
LEVEL CONTROL (LEVEL)
Level control for adjusting the amplification
of the signal at the INPUT 2 input.
2.2 Power Amplifier and Cooling
This is a powered loudspeaker with a very high efficient
amplifier module and as a result does not overheat. The
temperature of the amplifier module is monitored. In the
rare event it does get too hot, it will automatically shut
down to protect itself. Once the temperature has returned
to within the operating range, the amplifier will turn back
on. This may happen when the speaker is operated in very
high ambient temperatures and the enclosure is exposed
to direct sunlight. Always ensure adequate cooling and ap-
propriate shade to keep the ambient temperature around
the speaker within the specified operating temperature
range.
CAUTION: The rear panel of the amplifier module
serves as a heat sink for the power ampli-
fier. Certain parts may be hot during opera-
tion.
2.3 Quickstart
This section outlines setup and operation of two A 112A
connected to a DYNACORD CMS mixer.
CAUTION: After system installation is complete, power
on the mixing console first and position the
master faders at the lowest setting before
powering on the A 112A. Use the output fad-
ers to establish the desired volume setting.
Otherwise, switching and power-on noise or
the high level audio signal of an inadver-
tently playing audio source could result in
high acoustic outputs, which in some cases
might lead to hearing damage.
1. Place the A 112A, mounted on pole-mount stands to
the left and to the right. The lower edges of the
speaker systems should be approximately at a height
of 1.8 meters to provide sufficient coverage and to
prevent that listeners nearby are subject to extreme
sound levels.
2. Using suitable XLR-type cables connect the Master
Outputs of your mixing console, e.g. DYNACORD
CMS 1000, to LINE 1 of the left or right A 112A. Posi-
tion the master faders on the mixer to the minimum
setting. Now, turn on the mixer.
3. Connect the A 112A to the mains outlet using the
supplied mains cord. Plug the connector into the
MAINS IN socket. Use the POWER switch to power-up
the A 112A.
4. Set the LEVEL and VOLUME controls of the A 112A to
0dB.
5. Select FULL RANGE and MAIN to operate the speak-
ers as a main PA system.
6. Connect a audio source, e.g. CD player, to a line level
input of the mixer, e.g. CMS 1000. Set all rotary con-
