Audio Splitters

Product Overview

Due to changes to transmission path faults in AS1670.1:2015 (clause 2.6e), there is a requirement to split the audio output of the individual emergency zone amplifiers into audio multiple feeds.

If the audio is required to be split at the panel, then there is a 4 way audio splitter (154-0280), with each audio feed capable of handling up to 100watts. The total audio power handled by the splitter is 250watts. Each audio feed is individually supervised and isolated. Up to 4 4 way splitters can be connected to each EV3000 amplifier (40W, 120W, 240W or 480W)

A power supply (154-0278) is required for every 10 4 way audio splitters.

If the audio is required to be split remote from the panel, then there is a 2 way remote audio splitter (4210-0143/111). The audio feeds can handle up to 60watts each, with a total of 120watts per splitter. Each audio feed is individually supervised and isolated, and passes the fault condition back to the EV3000 audio amplifier.

The 2 way Remote Audio Splitter is available as DIN mount or enclosed versions.
