4.0 – Amplification and Audio
The X3-SP and X3-DFSP both include a highly advanced 64-bit DSP processing card to
handle all crossover points, system EQ, gain and delay settings, which are accessed by
means of preset programs that are factory installed into the unit. This DSP card feeds a
Class-D amplifier package (2 channel for the X3-DFSP, and 3-channel for the X3-SP)
providing ample power to drive your loudspeakers to their full potential. The amplifier and
DSP combination also provides full limiting and remote monitoring. Both the X3-SP and
X3-DFSP also include a drive unit test system to provide a quick on-site drive unit electrical
status report.
4.1 - Audio Inputs
The loudspeakers are supplied with female XLR input connectors, and male XLR link
output connectors. Both of these connectors are wired pin 1 screen, pin 2 positive, pin 3
negative. The X3-SP and X3-DFSP loudspeakers can accept both analog and digital
AES/EBU inputs. The factory default setting is analog – see later in this manual for details
on selecting digital input.
