pass TM X2.2 Owner’s Manual Aug 10, 2006 X2.
Introduction The X2.2 is an ultra high quality non-remote linestage audio preamplifier with internal power supply. It combines a completely new circuit topology with traditional construction representing thirty five years of preamplifier design. This preamplifier flows from a commitment to create the best sounding product: a simple circuit with the most natural sonic characteristics. Derived from US Patent # 5,376,899, the X2.
Setup The preamplifier has four sets of input connections, both singleended and balanced output connections, and a separate tape loop. The preamplifier’s voltage and current rating are indicated by affixed tag on the bottom of the preamplifier. It will indicate either 240 volts, 220 volts, 120 volts, or 100 volts. A 0.5 amp 3AG slow blow fuse is provided with 100-120 volt units, and a 0.25 amp slow blow fuse is provided with 220-240 volt units.
the front panel. Input 5 (TAPE IN) is deliberately not available through the tape output connection. The tape input is designated for use with a tape recorder if you have one, and we have arranged that it will not place its output on the tape out, which will prevent you from accidentally creating a feedback connection with your tape machine.
control buttons, indicated by up arrows (^) and down (v) arrows. Above the volume controls are two vertical arrays of 4 LEDs each. This indicator is likely different from what you are accustomed to. We think you will appreciate how easy it is to read from a distance. The left most LED array is decade and the right most array is range. Associated with the volume control is one additional light and a function control button labeled as “MUTE”.
assuring precise level steps and high common-mode rejection in balanced circuits. Wayne Colburn’s exceptional volume control, in conjunction with the unique LED display, gives the user the ability to replicate volume levels with absolute accuracy in steps of roughly 3dB. Product Philosophy 1) Circuit simplicity and a minimum number of components is a key element. The fewer parts in series with the signal path, the better.
the total mismatch to about .1%, for a common-mode rejection of approximately -60 dB. The input system of the preamplifier will exhibit full common-mode noise rejection with passive balanced sources, where the negative input is connected to ground at the source through the appropriate source impedance. This allows adaptation of unbalanced sources to balanced operation with passive cable connections in a manner that achieves the noise rejection of active balanced sources.

Warranty Information Please check with the factory-authorized distributor in the country you are purchasing this product for specific warranty information. All Pass Laboratories products purchased from an authorized Pass Laboratories dealer in North America are covered by a transferable, limited 3-year warranty. This warrantee includes all parts and labor charges incurred at the repair facility in addition to return shipping to the domestic customer, exclusive of subsequent damages.
For your protection please read the following: Water and moisture: Electrical devices should not be used near water ( as per example, near a bathtub, washbasin, kitchen sink, laundry tub, wet basement or swimming pool ). Care should be taken such that objects do not have the opportunity to fall, and that liquid is never spilled onto or into the device enclosure through openings.
