BYPASS button/led
When lit, the effects are bypassed and only the input signal is passed to the Xpression
™
outputs.
11
INPUT LEVEL meter
These LEDs provide visual indication of the peak level of the input signal when the
preset number and title are displayed. For the optimal signal-to-noise ratio, it is best to
adjust the input level so that the last LED (0dB) is rarely lit. This will guard against the
possibility of overdriving the unit.
These LEDs also display the final digital mixer output levels when any other functions
are displayed. This will help you to guard against clipping the output of the mixer at the
digital-to-analog converter.
12
INPUT LEVEL control
This control adjusts the unit’s gain to match the signal level at the input of the
Xpression
™
. Use the INPUT LEVEL meter to determine the setting of this control.
13
OUTPUT LEVEL control and CLIP LED
This control is used to adjust the overall output level of the unit.
The CLIP L.E.D. is part of the output section and, when lit, indicates that the final analog
output is being overdriven due to the Effects Level, Direct Level and Output Level being
set too high. If this should occur, reduce these levels until the L.E.D. does not light.
14
REFERENCE LEVEL switch
This switch adjusts the output range of the unit and may be set at either -10dB or +4dB.
When using the Xpression
™
with professional studio equipment providing a nominal
input level of +4dB, it is recommended that the +4 setting is used for best results. If the
Xpression
™
is to be connected to a high sensitivity input, such as the input to a guitar
amp, the -10 setting should be used.
