XD-2 Features
Front Panel
1
INSTRUMENT button
Push this button in when directly connecting a guitar or other direct instru-
ment. It adjusts the input impedance of the 1/4" TRS/TS input so you can
plug an instrument directly into the XD-2. It does not affect the XLR input.
2
High-Pass Filter button
This button inserts a high-pass fi lter in the digital signal path (before the
adjustable DSP section). You also have the option to enable a low-pass fi lter
using the XD-2 software. The high-pass and low-pass fi lter corner frequen-
cies can be adjusted in the software (see page 41).

Input Meter LEDs
Each channel has three LEDs which indicate the digital signal strength as
follows. (They also fl ash briefl y/hypnotically during power-up).
Green (-30) lights when a signal is present. These show that your input
sources are passing signals into the XD-2.
Yellow (0) lights when a nice average signal level is reached. Turn up the
GAIN knobs until these LEDs blink frequently or continuously.
Red (OL) lights as a warning when the signal levels are too high and are
about to overload. Turn down the GAIN knobs until these do not light at
all, or only blink occasionally during the highest peaks. If the red LEDs
blink frequently or continuously, you run the risk of causing digital clipping
(arrrgghhh). See page 66 for more details about these Meter LEDs.
