Master Audio
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 UBX hanging support (see accessories).

2.1. Technical description

The X12CE and X15CE cabinets come with DSP control, full range sound delivery
thanks to their direct radiation coaxial transducer and acoustic bass reflex cabinet. As
a full range system, its response is 58Hz-18kHz (+/- 3dB) with a usable bandwidth
between 50Hz-20kHz (-10dB) for X-12CE and 53Hz-18kHz (+/- 3 dB) with a usable
bandwidth between 45Hz-20kHz (-10dB) for X-15CE.
They have 1000W continuous amplification (800W + 200W), thermal protection,
output short circuit protection, 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 Ethernet
connection. The FACTORY preset gives a maximum flat response in free field
conditions; NEARFIELD has -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 X12CE and X15CE cabinets are connected using the XLR balanced connector.
Mains supply is through PowerCon at 230V.
They are built in birch plywood, which has a high resistance to vibrations and
humidity with black Polyurea paint finish. The front face is protected by a 1.5 mm
thick steel grille with acoustically transparent grey cloth.
Wedge shape. As onstage monitor, the front baffle is oriented at 35º from vertical.
They include one in-built lateral handle for an easy and comfortable transport.
