XP-30 Owner’s Manual

Additional channels beyond the normal two may require a different fuse value, please contact the factory for your specific application.

The input frequency rating of the power-supply is presumed 50-

60 Hz in all instances. Some individuals may wish to use a power regeneration apparatus, and slightly higher lines frequency is presumed acceptable. The preamplifier typically 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.
