- Page 2 LED or LCD display. Very few people are involved in the production of this product. I supervise all phases of the construction, and I test each pre-amplifier myself. If you have questions, comments, or problems, please feel free to contact me directly.
- Page 3 100-120 volt units, and a 0.25 amp slow-blow fuse is provided with 220-240 volt units. The frequency rating of the X0.2 power supply is 50 to 60 Hz. This pre-amplifier typically draws 30 watts during operation. Please verify that the input power rating as indicated on your unit is consistent with that supplied in your area before attempting hook up.
- Page 4 We have provided a standard IEC AC power cord that fits into the IEC line receptacle at the rear of the pre-amplifier power chassis. The pre-amplifier is equipped for operation with an earth ground provided by the user’s AC outlet.
- Page 5 There are a total of five inputs, a separate tape loop and two outputs on each of the pre-amplifier chassis. One chassis is exclusively dedicated to right channel and the other exclusively left channel. Balanced inputs and outputs are via XLR connectors. Single- ended inputs and outputs are via RCA connectors.

Page 6: Description Of Operation
Pass Labs product. The two front panel mode switches move the pre-amplifier and its display through 9 different functions. From virtual left to virtual... - Page 7 The up arrow toggles to a straight through function with neither attenuation nor gain. This function is useful in that it allows the pre-amplifier to function as a unity buffer for use with components that best function with their own volume controls, such as surround processors.
- Page 8 The electronic volume control allows greater than 70 dB range and is driven by a micro-controller that reads the optical encoder which serves as a front panel volume control. In this manner tracking of the volume for the two balanced channels is possible with accuracy unavailable on any ordinary volume control, assuring precise level steps and high common mode rejection in balanced circuits.
- Page 9 In this case we have been able to keep the total mismatch to about .1%, for a common mode rejection of greater than -60 dB. The input system of the pre-amplifier 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.
