draws 45 watts of power from the utility mains during operation as a 2 channel
preamplifier. Additional channel demands increase the demand for line wattage by
approximately 15 watts per channel.
We have provided a high quality standard IEC AC power cord that fits into the IEC
320 line receptacle at the rear of the power supply / control chassis. This is the
power cord we use for all product evaluation. You may substitute an equivalent
“after market” power cord of your choosing; however, we strongly suggest that any
cord you select must carry all appropriate government certifications for your location.
Under no circumstances defeat the safety ground provided by the power cord. We
have provided internal isolation to help prevent ground loops. If ground loops exist
in your system which suggest to you that you might want to disconnect this earth
ground, please contact your dealer or the factory first. Be aware that some of the
internal noise filters of this product presume a good earth ground through the power
cord. Removing that ground may compromise system performance.
Do not plug in the power cord yet.

Place the components that comprise the XP-30 in the locations where you plan to
use them. They don't need a lot of ventilation, but a little is helpful.
On the rear of each control chassis are two identical DIN-25 sockets in parallel with
one another. You may connect either socket to the control chassis, as previously
indicated they are identical. The second socket provides daisy chain capability for
additional gain channels.
The DIN-25 connecting cables only communicate power, and control commands to
the gain stages. At no time does audio signal cross the DIN-25 umbilical cables.
Keeping each gain channel chassis 100% isolated from every other gain channel
chassis reduces channel cross-talk to a near theoretical minimum.
Connect the power supply / control chassis to the gain stages by the supplied DIN-
25 umbilical cables. They must be pressed firmly into the receptacles, keeping in
mind that the connector shell is trapezoidal, which keys the proper orientation.
Finger tighten the screws on either side of the connector shell. Do not use
excessive force, take care not to cross thread the screws.
Third
There are a total of seven inputs on each chassis. The first inputs are numbered 1-
5. Input 6 has been named “Pass-Thru” and is intended for use with a home theater
processor (see the later notes on use of input 6). Input 7 is the tape loop.
The XP-30 is shipped with shorting plugs on the input XLR connectors which
connection the (-) pin 3 input to the ground pin 1 input. Save these jumpers. They
are not only gold plated and thus valuable, but you will need them when you wish to
