Figure 5: DSP architecture
5.2.4 Amplifier section
The LA8 amplifier section uses a Class D technology supporting the wide dynamic range encountered in live audio
productions. The 4 channels can deliver up to 4 x 1800 Watts into 4 ohms yielding power matching for all L-
ACOUSTICS
®
loudspeaker systems.
The auto-sensing SMPS (Switched Mode Power Supply) offers better stability by associating two symmetrical power
supplies. The power supply architecture optimizes the power resources distribution with respect to each amplifier
output channel requirements.
5.2.5 Speaker output
The LA8 features two 4-point SpeakON
®
connectors and one 8-point CA-COM
®
connector for loudspeaker outputs.
The 8-point CA-COM
®
connector on the LA8 is fully compatible with all 8-point L-ACOUSTICS PA-
COM
®
cables EXCEPT for the DO2W, DOFILL and DOSUB cables.
Refer to LA8 PACOM CABLES Technical bulletin [3.4] for more details.
