Running in

Speaker drivers contain moving parts. It is recognised to be good practice to run in new speakers prior to 
normal use for improved bass extension, sweeter highs and a smoother performance overall. This process is 
also referred to as 'breaking in' or 'burning in'.

We recommend a run-in period of at least 12 hours (or overnight); ideally longer. 

Having observed the warnings on page 3 of the manual, connect an audio playback device (CD, MP3 player, 
etc.) to THE BOULDER speaker(s). Place the playback device in loop mode and play dynamic music through 
THE BOULDERs at a 

moderate

 level; enough to drive (move) the speaker diaphragm a reasonable amount.

Power

THE BOULDER voltage is factory set. Options are:

220-240v

110-110v

100v

An arrow on the voltage setting label (see p. 6) indicates the voltage setting of THE BOULDER.
IMPORTANT: ensure THE BOULDER is set to the correct voltage for your region. Voltage settings must be 
set by the factory and cannot be switched by the user. If THE BOULDER is set to the incorrect voltage for 
your region contact Unity Audio. DO NOT power it up!

Fuse replacement

The fuse is located on the rear of  THE BOULDER in the fuse holder between the power switch and IEC mains
input socket [Image A]. Remove the mains lead. Prise out the fuse holder by placing a small slotted 
screwdriver into the slot located on the underside and near the front of the fuse holder [Image B]. Carefully but
firmly pull the fuse holder outwards. Replace the fuse {see 'Specifications' (p.9) for fuse type.}. Push the fuse 
holder back into position.

Clean the cabinet with a soft, lint-free cloth. The use of solvents or abrasive cleaners should be avoided.
