How do I…
Build a 70V or 100V line
Each zone of 70V or 100V speakers is one line, wired as a chain from where its cable enters; choose its cable and voltage, and add a subwoofer to it.
Where to find it: the Cabling tab › Groups › its line, such as 70V-A, or a speaker's Properties › Cabling › Line
A new landscape speaker starts at 70V (100V in a European workspace), and any passive speaker does once you choose 70V in its Power; see set a speaker to powered or 70V. Speakers connected into one zone are one line — a Cable group at their rack or panel — and the next zone is the next line: 70V-A, 70V-B. To move a speaker to another line, connect it into that zone or disconnect it from its own; unlike keypads and fire alarm devices, a line has no New group.
How a line is wired
The line's cable enters one speaker, its entry: the one a conduit reaches, otherwise the speaker placed first — never a subwoofer. From there each speaker's cable comes from its neighbour toward the entry, so an entry in the middle of a zone makes two branches. Each piece is its own cable with its own Cable ID and length, and each speaker's cable card shows the piece that reaches it: "→ LS-2", or its rack's or panel's Number for the entry.
- In the Cabling tab's Groups, click the line under its rack or panel. It opens in place, says where the cable enters and lists every piece, such as "R-1 → LS-1 · 16/2".
- Its cable is 16/2 (2×1.5 mm² in a European workspace) unless you choose another. Past about 300 ft (90 m) on that cable, the line takes the heavier 14/2 (2×2.5 mm²) on its own.
- For a 100-volt line, the European norm, click 100V. The line becomes 100V-A and its speakers read LS/100V-1. 70V switches it back.
From the drawing: select a speaker, and its Cabling shows its Line. Click the line's name to select every speaker on it; Properties then shows the same line settings as Groups.
Until a zone's line is stored — on a drawing from before lines were zones — the zone shows in red in Groups and under Totals, and a version cannot be saved: connect or disconnect one of its speakers and the line is stored.
Chain-placed from a speaker on a line, or connected to one, a speaker takes that line's voltage. A speaker whose voltage differs from the rest of its zone is warned, with a button that sets it and puts it on the zone's line. Past your company's limit the line is marked in red: split its zone to start another line.
A subwoofer on the line
- A 70V subwoofer is a member like any other, on the line's two conductors.
- An 8Ω subwoofer needs a pair of its own. Chain-place it into the zone, or connect it, and it branches off the speaker before it: every piece from the rack or panel to that speaker becomes four-conductor (16/4, or 14/4), and the subwoofer's own piece and the next speakers stay two-conductor (16/2). Disconnect it and it runs to its rack or panel again.
Switching the voltage never changes an 8Ω subwoofer.
