POSITIONING AND FITTING

WARNING: Non-compliance with the instructions or neglecting warnings may cause malfunction or even damage the unit:

1. Avoid turning on the device without the speakers connected to its outputs and without having previously set the volume/gain controls to minimum level.
2. Always use shielded cables to make connections between devices.
3. In an amplifier, avoid placing the speaker output cables close to other signal cables (micro, line…). This may cause the system to oscillate, damaging the amplifier and speakers.

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 doesnot 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

8.1 Mains connection
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.
8.2 DANTE™ audio inputs
eCA120DN / eCA120HZDN allows the reception of 2 DANTE™/AES67 audio signals via Ethernet by means of an RJ-45 connector. Routing of DANTE™/AES67 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
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.
8.3 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.
8.4 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 4 . For a proper performance, the unit must not work under lower impedance than previously specified, under no circumstances.
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 subwoofer for bass reinforcement.
8.5 Remote control port
The RJ-45 (REMOTE VOLUME) connector allows to connect a WpaVOL-type wall control panel (or another model of the Wpa series) to adjust the overall output volume. The connection is made with a standard CAT5/CAT6 cable between the Wpa wall panel and the REMOTE connector of the eCA120DN / eCA120HZDN.

OPERATION AND USAGE

9.1 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.
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).
9.2 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™/AES67 (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.
9.3 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 intoAUTO STANDBY mode.
b) There is an audio signal in the inputs. Result: the amplifier stays active.

9.4 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).

9.5 Setup switches

• INPUT SELECT: selects the audio input (program audio)
  • LINE IN: analogue audio input
  • DANTE: DANTE™/AES67 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

eCA120DN / eCA120HZDN must not be cleaned with solvents or abrasive substances which may damage the prints. Clean using a dry cloth. Under no circumstances allow water to enter any of the orifices in the equipment.
