Amate Electroacústica,s.l.
2. X-12C
The X-12C cabinet is ideal for a multitude of applications. It includes 750W bi-
amplification for the mid range woofer, 250W for the high range compression driver
and digital signal control by DSP. The manufacturer presets FACTORY, NEARFIELD,
SPEECH, MONITOR, and XOVER make it easy, flexible and user-friendly.
In terms of its electro-acoustic qualities, the coaxial transducer gives a totally
symmetrical response free of null zones from polar lobbing effect. It comprises a 12"
woofer with a 3" voice coil and a compression driver with 3" voice coil and titanium
diaphragm.
The result is a clean, high quality sound whether for nearfield listening or at full power
in larger sites.
Thanks to its wedge shape it can be used as an onstage monitor, obtaining stable,
homogeneous response and coverage.
The upper and lower surfaces incorporate a pole mount socket for a standard 35mm
tripod, which at the same time allows for the use of a hanging support (see
accessories).

2.1. Technical description

The X-12C cabinet comes with DSP control, full range sound delivery thanks to its
direct radiation coaxial transducer and acoustic bass reflex cabinet. As a full range
system, its response is 58-18kHz (+/- 3dB) with a usable bandwidth between 50Hz-
20kHz (-10dB).
It has 1000W continuous amplification (750W + 250W), thermal protection, anti-short
circuit protection at the output, maximum power limiters for each channel, and
protection against overvoltage. The DSP includes 5 presets which can be selected
either accessing the cabinet's rear control panel or via the computer with RJ45
connection for the RS485 bus. The FACTORY preset gives a maximum flat response
in free field conditions; NEARFIELD has +3dB in high and low frequencies, -3dB in
mid range for medium volume, close range listening; SPEECH has -9dB bass, -6dB
high for voice use with a microphone; MONITOR gives a flat response in half space
(floor position); XOVER has a high pass filter at 100Hz for bass frequency back up
(subwoofer).
The X-12C is connected using the XLR balanced connector. Mains supply is through
PowerCon at 230V.
Built in birch plywood, which has a high resistance to vibrations and humidity.
Varnished finish and optional (by order) textured water-based acrylic resin black paint
which is totally ecological. The front face is protected by a 1.5 mm thick steel grille
with acoustically transparent grey cloth.
Wedge shape. Height 56cm, width 41cm, depth 40.1cm. As onstage monitor, the
front baffle is oriented at 35º from vertical.
