The ARCS

WIDE/FOCUS and the SB18m can be amplified by the LA4 or the

LA8 amplified controller.

Option A:

Connect a DO cable (DO.7, DO10 or DO25) to the PA-COM

connector of the LA8 and use the DOSUB-LA8 to

split the audio signals into four channels, each one feeding one similar enclosure. With various enclosure types, for

example 2 ARCS WIDE FOCUS and 2 SB18m, this cabling scheme needs a dedicated custom preset.

Option B:

Connect an SP cable (SP.7, SP5, SP10 or SP25) to one of the SpeakON

connectors of the LA8, and use the SP-Y1

One additional similar enclosure can be connected in parallel with each of the first ones, by using SP cables.

Using cable other than specified in this document to connect a subwoofer via the PA-COM

WIDE/FOCUS or SB18m).

8 Ω for 1 enclosure, 4 Ω for 2 enclosures in parallel (ARCS

WIDE/FOCUS or SB18m).
