What? Me read a manual?
Before you begin, please make sure you read the
Safety Instructions on page 2 and Getting Started
on page 4.
Your new Mackie TH-18s powered subwoofers
are designed to set up quickly and operate easily.
We know it’s often seen as a sign of weakness to
read a manual, along with asking for directions
when lost, but we hope you will read the rest of the
manual, at least while nobody is looking.
It is important to keep your receipt in a
safe place, and not a bad idea to write your
product information below for future reference
(i.e., insurance claims, tech support, return
authorization, etc.).
Don’t forget to visit our website at www.mackie.com
for more information about this and other Mackie products.
Subwoofer 1 Subwoofer 2
Please write the serial number for your TH-18s here
(or for both TH-18s’s if you have two) for future reference (i.e.,
insurance claims, tech support, return authorization, etc.):
