(12) INPUT LEVEL meter:
These LEDs provide visual indication of the peak level of the input signal. 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.
(13) INPUT LEVEL control:
This control adjusts the unit's gain to match the signal level at the input of the
Intellifex LTD. The gain can be adjusted from -12dB to +12dB. Use the INPUT
LEVEL meter to determine the setting of this control.
(14) CLIP L.E.D.:
This L.E.D. is part of the output section and, when lit, indicates that the final analog
output is being overdriven because the Effects Level, Direct level, and Output Level
control are set too high. If this occurs, reduce these levels until this L.E.D. does not
light.
(15) OUTPUT LEVEL control:
This control is used to adjust the output level of the unit and may be adjusted from
zero signal to a small amount of gain.
(16) REFERENCE LEVEL switch:
This switch determines the output range of the unit and may be set at either -10dB
or +4dB. When using professional studio equipment providing a nominal input level
of +4dB, it is recommended that the +4 setting on the Intellifex LTD be used for
best results. If connecting the Intellifex LTD to a high sensitivity input, such as the
input to a guitar amp, the -10 setting should be used.
