INTRODUCTION
eCA120DN is a 2 x 60 WRMS @ 4Ω high efficiency (class D) stereo compact amplifier.
It features 2 x analogue audio inputs and 2 x Dante
TM
audio inputs, both with
selectable priority function (over the other input signal) as well as an auxiliary audio
output. Auto stand-by function (selectable) and fanless design (100% silent). It also
has a remote control volume port compatible with ECLER WPm wall-panel control
series. Universal external power supply included.
eCA120HZDN is a 120 WRMS @ 70V / 100V efficiency (class D) mono compact
amplifier for high impedance lines
, with the same features than eCA120DN.
KEY FEATURES
• 2 x 60 W RMS @ 4 Ω output (eCA120DN)
• 1 x 120W RMS @ 70V / 100V output (eCA120HZDN)
• 1 x auxiliary audio output (Euroblock connector), for connecting to a sub-
woofer unit e.g.
• 1 x unbalanced stereo input (LINE INPUT), with dual RCA connector and 3-in
Euroblock connector
• 2 x Dante™ audio input (DANTE INPUT), with RJ-45 connector
• Selectable PRIORITY FUNCTION with selectable priority signal: the analogue
audio input (LINE INPUT) can be selected as priority signal over the Dante™
audio input (DANTE INPUT), or vice versa.
• Priority release time adjustment (FAST / SLOW).
• Selectable AUTO STANDBY function: in the absence of an audio signal the
unit automatically goes into STANDBY mode, minimizing power
consumption.
• Gain adjust of audio inputs on front panel (trimmers)
• Local volume control by knob
• Remote volume control (RJ-45 connector.) via WPm wall-panel control series
(0-10 VDC).
• Lightweight, silent, high-performance amplifier (fan-free convection cooling)
External, universal power supply (included)

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.
