Speck Electronics Xtramix - Manual (Page 17)

The following chart represents the DC voltages available at the 6 pin
connector on the Model PS3-1.5 Power Supply.
In order to install the Xtramix in a 19" equipment rack, it will be
necessary to attach the two rack mount adapters to the main chassis of
the Xtramix. Each rack mount adapter is attached to the main chassis of
the mixer with (3) 6-32 x 3/16" Phillips machine screws.
Using a Phillips screwdriver, remove the (6) screws installed on both
sides of the mixer. Position the adapters so the side with the small round
holes match the threaded holes on the sides of the Xtramix, and the side
with the oval shaped holes are towards the front panel of the mixer.
Attach the rack mount adapters to the left and right sides of the chassis
with the (6) screws and tighten.
Before any attempt is made to operate the mixer, it would be a good idea
to set all the mixers controls to their neutral positions. This gives you a
reference point to work from when adjusting controls and switches.
All volume controls including effects sends, effects returns, and master
level controls should be set to their full counter-clockwise setting. All
pan controls should be set centered. All pushbutton switches on the
front and rear panel should be set to the out position.
When any future reference is made to the controls or switches of the
Xtramix, is will be assumed that they have been set to their neutral
positions.
