  Only use attachments/accessories specified by the manufacturer.

8.

  Use only with a cart, stand, tripod, bracket, or table specified by the

11.

 Exposure to extremely high noise levels may cause permanent hearing 

loss. Individuals vary considerably in susceptibility to noise-induced 

hearing loss, but nearly everyone will lose some hearing if exposed to 

sufficiently intense noise for a period of time. The U.S. Government’s 

Occupational Safety and Health Administration (OSHA) has specified 

the permissible noise level exposures shown in the following chart.

  According to OSHA, any exposure in excess of these permissible limits 

could result in some hearing loss. To ensure against potentially danger-

ous exposure to high sound pressure levels, it is recommended that all 

persons exposed to equipment capable of producing high sound pres-

sure levels use hearing protectors while the equipment is in operation. 

Ear plugs or protectors in the ear canals or over the ears must be worn 

when operating the equipment in order to prevent permanent hearing 

loss if exposure is in excess of the limits set forth here.

Introduction

Thank you for choosing the Mackie Hotwire EX12 

extension speaker cabinet for the Hotwire VT12 profes-
sional guitar amplifier. The EX12 is built from the finest 
materials and components available. The cabinet is 
carefully constructed and then covered with extremely 
tough fabric-backed vinyl. It contains a 12" Mackie 
custom-voiced neodymium speaker.

The Hotwire EX12 has a 1/4" phone plug input on 

the back of the cabinet for connecting it to the exter-
nal speaker jack on the back of the VT12, the perfect 
complement for extending the volume and sound of your 
VT12 guitar amplifier.

Input Plate

Connect the external speaker jack on the back of 

the VT12 (or the output of your amplifier rated up to 
100 watts into 4 ohms) to this 1/4" jack using a speaker 
cable.

Note:

 Do not use a guitar cord (shielded cable) to 

connect an amplifier to a speaker cabinet. Guitar cords 
are not designed to handle the higher currents provided 
by an amplifier.
