Front Panel Desccription

9 FUNCTION SELECT control

This control allows access to each function of the Xpression

™

. These functions include:

Global Delay Chorus MIDI Channels Mixer

Reverb Pitch Shift Title Edit MIDI Dump/Load HUSH

Tremolo Rotary Speaker Controller Assig Factory Restore Compressor

Phaser Copy Remote Control EQ Flanger

Speaker Sim Program Changes Config Select

10 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.

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.
