ARCS
®
II
The ARCS
®
II is exclusively bi-amplified by the L-ACOUSTICS
®
LA8 amplified controller.
To cable L-ACOUSTICS
®
2-way active enclosures with the LA8, three options are available:
Option A:
 Connect a DO cable (DO.7, DO10 or DO25) to the PA-COM
®
connector of the LA8 and use the DOFILL-LA8 to
split the audio signals into two channel pairs, CH(A) and CH(B), each one feeding one ARCS
®
II enclosure.
Option B:
 Use an SP cable (SP5, SP10 or SP25) to connect one enclosure to one of the two SpeakON
®
connectors of the LA8.
Option C:
 Connect a DO cable (DO.7, DO10 or DO25) to the PA-COM
®
connector of the LA8 and use the DO3WFILL to
split the audio signals into one channel pair, feeding one ARCS
®
II enclosure, and two single channels, each one feeding
one SB28 subwoofer.
This cabling scheme needs a dedicated custom preset.
Two additional enclosures can be connected in parallel with each of the first ones, by using SP cables (SP.7, SP5, SP10
or SP25).
PA-COM
®
standard
Using cable other than specified in this document to connect a 2-way active enclosure via the PA-COM
®
connector of the LA8 may lead to speaker damage. Refer to the LA8 PACOM CABLES technical bulletin.
Maximum of 6 ARCS
®
II enclosures per LA8
3 ARCS
®
II enclosures can be connected in parallel to each pair of output channels on the LA8 (1/2 and 3/4).
Impedance load
8 Ω for 1 enclosure; 4 Ω for 2 enclosures in parallel; 2.7 Ω for 3 enclosures in parallel.
