XP-30 Owner’s Manual

The XP-30 is a modular preamplifier consisting of one control / power supply chassis and additional gain chassis, each containing the analog circuits of a single channel. The XP-30 is meant to typically be used as a two-channel product, but you can use the control chassis to serve up to six channels.

Each channel individually provides master and slave outputs. The relative level between the master and slave outputs of each channel is adjustable by a knob on the front panel of each individual gain chassis. If you have ever wanted to bi-amp your loudspeakers, you might appreciate that this feature allows easy use of different types of amplifiers for the low vs the high frequencies, adjusting the relative levels as needed. If you need big power and control on the bottom but want the sweet character of tubes on the top, you may wonder how you ever got along without this. Or why other companies don’t offer it.

It is even useful when the same types of amplifiers are used – typically without the full load on each amplifier the subjective balance still needs minor tweaking.

All connected gain chassis respond to the master level adjustment on the main control chassis through a completely new volume control covering a range of 100 dB in precise 1 dB steps.

Both outputs of each channel are offered as single-ended and balanced outputs having the same gain and impedance and both may be used simultaneously with no degradation.

There are five (5) regular inputs, a special home theater bypass input and tape input for those needing any side loops for recording or signal processing.

The control chassis also supports a mono function between the separate different analog stage chassis.

The power supply in the control chassis is large enough for somebody else’s power amplifier. It contains a pair of highly efficient, low-noise Plitron transformers in dual mono topologies, emi filtering, large capacitance reservoirs, and of course the isolation that comes with being in a different chassis from the analog gain stages.

Something else that was on Nelson’s wish list – the ability to drive an amplifier output stage by itself: Do you require a preamplifier deliver a fraction of a volt to the power amplifier or peaks in excess of 50
