XP-30 Owner’s Manual

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.

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 operate an input with RCA (single-ended) connections. The XLR pins are numbered, but you’ll have to look close, maybe with a hand lens.

There are two sets of balanced and single ended outputs on each channel, designated “master” and “slave”. You may connect and use as many of these outputs as you wish without degradation of signal. Each output is derived from it’s own circuit element and is totally independent of any other outlet. On the XLR, pin 1 is ground, pin 2 is positive and pin 3 is negative.

The XP-30 also incorporates a “tape-loop” for those users who either record or wish to insert a processor loop as a side chain. Tape out communicates directly back to the input bus, bypassing the volume control. Tape out is always active, with one exception, where Tape Out is isolated from Tape Input to avoid a feedback loop.

The tape loop is only available from the remote control and is selected or deselected by a single keystroke of the “Tape” button on the hand remote. When tape is selected from the hand remote, the display on the power supply shows a lower case “t” on the right hand side of the display. When the letter “t” is showing, the tape input

is “selected” and all other inputs are “deselected”, regardless of any previous settings you may have chosen. Pressing the “Tape” button a second time, cancels the command.
