Installation
Voltage Selection
Before connecting the PQ to the mains, make sure that the voltage selection corresponds
to the values of your local power grid (230 or 115 volts) Inside the power connector, to the
right, next to the on/off switch, there is an opening that displays the voltage selected. If
the voltage indicated does not correspond to the one required, change it by following this
procedure:
Open the power connector lid with a small screwdriver (use the tiny slots on the right hand
side). Use the screwdriver to lever the red fuse holder from above until you can grab it.
Take the fuse holder out and replace the fuse with one corresponding to the local power
gridspecifications.Youcanfindtheadequatevaluesontherearoftheunitoronpage12
of this user‘s manual. Turn the fuse holder around 180 degrees and place it back again.
When you close the lid again, you should see the correct voltage displayed in the opening

or emanates heat. Avoid exposure to heat, moisture, dust, and vibrations. Do not install
the PQ close to any power amps or digital processors. Instead, install it in a fully „analog
rack” where any interferences can be avoided (Word Clock, SMPTE, MIDI etc.).
The unit should be powered off before connecting or disconnecting any cables or equip-
ment to it.
Use the On/Off switch on the rear panel to turn the unit on or off. The illuminated red LED
in the middle of the front panel indicates the unit‘s operating status. The On/Off switch
was placed on the rear panel to avoid any emissions due to voltage-carrying conductors
running across the unit and affecting sound. When powering on or off, there‘s no need
