Compatibility
The xpressor 500 is a module to be installed into an API 500 se-
ries compatible rack frame (not included). It needs the power
supply and the audio connectors provided by this frame and
does not function stand alone.
The current consumption is 125 milliamperes at +/- 16 volts
DC. This is actually more than many other 500 series modules
consume as a result of the discrete class-A design of the xpres-
sor 500’s audio path.
Most API 500 compatible racks will meet this requirement
without problems, but there might be a limitation of how
many units can be installed in a single rack. In case of doubt
please check with the manufacturer of your specic rack.
Installation
Just follow these easy steps to install the xpressor 500 module:
1. Switch your API 500 series compatible rack o and discon-
nect the power cable from mains.
2. Insert the module into two free slots of your rack. Make sure
both PCB connectors match with the rack connectors.
3. Gently push the module in place - do not use any extensive
force here!
4. Tighten the front panel with four screws provided by your
rack manufacturer.
5. Connect your XLR audio cables (see page 6 for more info)
and apply power to your rack.
And this is already it. Have lots of fun with your xpressor 500!
