and speakers. The gain control toggles between two settings, offset
from one another by 10 dB. The high gain selects +10 dB and the
low selects 0 dB as the maximum volume (step 64) setting. We
suggest that you let your ears determine which setting conveys the
most sonic benefit in your system. Hi gain may be appropriate for
sources that output less than 2 volts rms single ended and 4 volts
rms balanced. When hi gain is selected the vacuum fluorescent front
panel display will indicate this choice by displaying an * next to the
volume setting. Low gain is the default setting.
The electronic volume control allows greater than 70 dB range and is
driven by a micro-controller that reads the optical encoder serving as
a front panel volume control. In this manner tracking of the volume
of 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. Wayne Colburn’s
exceptional volume control in conjunction with the fluorescent
display give the user ability to replicate volume levels with absolute
accuracy in steps of roughly 1 dB.
The remote control uses a multi-button direct access architecture.
This remote is designed to operate several pieces of Pass Labs
electronics, not all of the functions available on this remote will be
applicable to your Pass Laboratories XP-10.
The Remote control operation is, or should be very intuitive in
operation; we have attempted to make it’s operation as familiar
as possible. Where applicable the remote mirrors the front panel
controls.
Power, tape and ext. amp on (external amplifier turn-on) have no
reality with the XP-10. these specific control functions have no effect
on this product.
MUTE: pressing mute once will quiet the pre-amplifier outputs,
pressing mute a second time will return you to the previous volume
control setting
INPUT SELECTION: Pressing. 1,2,3,4,5 will immediately move the
input selection to that input selection, volume and balance settings
will not be disturbed.
BALANCE: Pressing balance left (<) or balance right (>) will
increase the level in the left or right speaker, depending upon which
button is pushed.
VOLUME: Pressing the increase (^) button or the decrease (v)
button will shift the volume setting 1dB, holding a button down will
increase or decrease the level until such time as you either release
pressure on the button or reach the limits of the volume control.
