POSITIONING AND FITTING
eCA120DN / eCA120HZDN is suitable for installation on a wall or under a surface
(table, shelf, cupboard, etc.), thanks to its design and layout of its connectors, controls
and LED indicator lights. Along with the optional 1UHRMKIT accessory (not included),
it is also possible to install the unit in a standard 19” rack (1RU height).
This unit is intended for users with low technical expertise, for this reason, all input
gain controls are accessible by means of an adjustment turnscrew, except for the
output level adjustments, controlled with classic rotary knobs, easily accessible from
the front panel.
Thanks to its low consumption and heat dissipation the eCA120DN / eCA120HZDN
does not require forced cooling, however, it must be prevented from installing the unit
in dusty environments with extreme temperature and/or humidity conditions.
The unit must be away from noise and interference sources (voltage variators, electric
engines, etc.) as well as mains cables.
CONNECTING
The amplifier is powered by alternating current through its external power source: 100240 VAC and 50-60 Hz.
The atmosphere should be as dry and dust free as possible. Do not expose the unit to
rain or water splashes. Do not place liquid containers or incandescent objects like
candles on top of the unit.
Should any work or connection / disconnection task be done, always
disconnect the unit from the mains supply. There are no elements that can
be manipulated by the user inside the unit.
To avoid buzzing, do not allow the power cable to intertwine with the shielded cables
that transport the audio signal.

Dante™ audio inputs
eCA120DN / eCA120HZDN allows the reception of 2 Dante™ audio signals via Ethernet
by means of an RJ-45 connector. Routing of Dante™ audio signals trough the Ethernet
network is achieved thanks to the Dante ™ Controller software. To learn more, check the
developer’s documentation:
www.audinate.com/products/software/dante-controller?lang=es"
Make sure that the front panel switch (INPUT SELECT) is in DANTE position, and then
adjust the DANTE input gain with the front panel trimmer (DANTE INPUT) until the
input audio signal is appropriate.
Analogue audio inputs
eCA120DN / eCA120HZDN input channel only supports stereo line signals (or two mono
signals). It has an unbalanced stereo connection with dual RCA connector and 3-pin
Euroblock connector (LINE IN). This input is designed to support -6dBV to 0dBV signals,
given that the rotary volume control of the front panel provides an extra +6dB of gain at
its maximum position.
This audio input can receive signals from CD players, radio tuners, mixing consoles,
media players, audio outputs of computers and tablets, etc..
LINE IN connections are linked, so that when you use one of them as an audio signal
input for your unit, you can use the other to send that signal to another unit or external
equipment.
Audio output connections
eCA120DN:
The powered output (OUT L y R) uses a Euroblock connector.
The connection cable that connects the eCA120DN connectors and the speakers should
be good quality, with a suitable cross section and as short as possible.
Keep in mind that, minimum nominal impedance for each cannel is 4Ω. For a proper
performance, the unit must not work under lower impedance than previously specified,
under no circumstances.

Page 7
eCA120HZDN:
The powered output (OUTPUT) uses a Euroblock connector with a common terminal
(0V), a terminal for a 70V line and another terminal for a 100V line. Always use the
common terminal and, depending on the type of speaker in the system, one of the two
others, 70 / 100V, to feed the loudspeaker line.
The connection cable that connects the eCA120HZDN connectors and the speakers
should be good quality, with a suitable cross section and as short as possible.
The OUTPUT provides a powered version of the mono-converted input signal.
Remember that the total power used by the speakers connected to the eCA120HZDN
output should not exceed the maximum power it can provide.
In addition, eCA120DN and eCA120HZDN feature an aux audio output (AUX OUTPUT)
with Euroblock connector. This stereo audio signal is identical to the powered signal,
but with LINE level. Perfect to connect an additional audio system like a self-powered
sub-woofer for bass reinforcement.
Remote control port
The RJ-45 (REMOTE) connector allows to connect a WPmVOL-type wall control panel
(or another model of the WPm series) to adjust the overall output volume. The
connection is made with a standard CAT5/CAT6 cable between the WPm wall panel and
the REMOTE connector of the eCA120DN / eCA120HZDN.
OPERATION AND USAGE
Start up
Start up the eCA120DN / eCA120HZDN by connecting the equipment to an external
power source to which the DC IN 24V connector of the amplifier has already been
connected. The LED indicator ON/STBY immediately lights up on the front panel. We
recommend you turn on all the devices in the following order: sound sources, mixer,
equalisers, active filters and processors and, finally power amplifiers. Powering off
should be done by following the exact reverse sequence. Following this order, the
introduced noise due to turning on or switching off the devices will not affect those
further on in the chain and will be inaudible.

Page 8
Once turned on, the front volume control (VOLUME) and the controller connected to
the REMOTE VOLUME port (if any) may be used to set the output volume of the signal
powered by the unit.
To select the audio input signal, use the switch located at the front panel (INPUT
SELECT).
Priority function
When the priority function (PRIO MODE) is activated, one of the input signals will
have priority over the other, that is to say, when signal presence is detected in the
priority input (signal level exceeds the threshold) the input signal selected with
INPUT SELECT switch will be attenuated.
For instance, if priority function is activated (PRIO MODE in ON position) and the
selected audio signal is Dante™ (INPUT SELECT in DANTE position), the priority audio
signal will be the analogue input.
The priority mode allows adjusting the attenuated signal recovery time (PRIO
RELEASE TIME), by means of a switch FAST / SLOW located at the rear panel.

Auto-standby function
The AUTO STANDBY function (idle or low consumption mode) means you can install the
eCA120DN / eCA120HZDN in inaccessible places and leave the device connected to the
mains power supply permanently because when no signal is detected, it automatically
goes into standby mode, saving energy.
To enable the AUTO STANDBY mode, the switch labelled "AUTO STBY" on the rear
panel has to be in the ON position. When it is enabled and after 2 minutes or more
without any audio signal at the audio input of the device (or a very weak signal, lower
than the activation threshold), the eCA120DN / eCA120HZDN will automatically switch
into standby mode, lighting up the red ON/STBY LED located on the front panel of the
device. When a valid audio signal is detected in any of the inputs, the amplifier leaves
standby mode and starts operating normally again and the ON/STBY LED goes green.
When enabling the AUTO STANDBY mode with the front panel switch (ON position),
one of the 2 following assumptions may occur:
a) There is NO audio signal in the inputs. Result: the amplifier immediately goes
into AUTO STANDBY mode.
b) There is an audio signal in the inputs. Result: the amplifier stays active.
LED indicators
• SP: The signal presence or SP LED indicator shows that there is a signal in the
amplifier input. This lights up when the input level reaches the established
detection threshold.
• CLIP: The saturation (or cut off) CLIP LED indicator comes on when the signal
delivered to the speakers is close to the amplifier's clipping or saturation level.
Input signals should be set to ensure the CLIP indicators never stay on, but that they
do so at most to the beat of the lowest sound frequencies. Otherwise the powered
signal will be distorted with low quality and low intelligibility.
Note: If the input signal is too high, the CLIP indicator lighting up very frequently
over a short time interval (a few seconds), the amplifier may go into protection
mode, being muted to return to normal operation in a short time.
• ON/STBY: The green light comes on when the equipment is in normal operating
mode and it goes red when it is in standby or low consumption mode (STANDBY).

o
LINE IN: analogue audio input
o DANTE: Dante™ audio input
• PRIO MODE: turns ON/OFF the priority function.
• PRIO RELEASE TIME: sets the attenuated signal (program audio) recovery time
(FAST / SLOW recovery).
• AUTO STBY: turns ON/OFF the AUTO STANDBY function. When the function is on,
the eCA120DN / eCA120HZDN will automatically go into STANDBY or low
consumption mode in the absence of audio signals in its inputs.
CLEANING

which may damage the prints. Clean using a dry cloth. Under no circumstances allow
water to enter any of the orifices in the equipment.
