Appendices

You turn on a CUE button in the EFFECT
PARAM screen, but it is automatically
defeated

❍ This is defeated automatically when you switch screens in the display. (→ p. 170)

When you recall a scene, it takes a
certain amount of time for the faders to
stop

❍ Could you have specified a fade time? (→ p. 143)

The panel LEDs or LCD display are too
dark / too bright

❍ This can be adjusted in the MISC SETUP screen. (→ p. 217)

Signal level of a specific frequency is
low

❍ Could the EQ gain be turned down excessively?

❍ Routing a signal through a GEQ or effect will delay it relative to other signals. If this signal is mixed with

the signal via a different signal path, a comb filtering effect will cause the level of a specific frequency
to be decreased.

Can’t control an external head amp
(AD8HR)

❍ Is the external head amp connected to the specified port?

❍ Is the audio output signal of the external head amp being input via an I/O card to SLOT 1–3?

❍ Is the input port of the external head amp set correctly?

❍ Could there be a problem with the cable that connects the LS9 and external head amp? Are you using

a D-sub 9-pin cross cable?

Can’t control the LS9 by LS9 Editor.

❍ Refer to LS9 Editor installation guide on our web site.

In the LCD display, there are some
black points (unlit) or white points
(always lit).

❍ Unfortunately, this is a common characteristic of TFT-LCDs and not a malfunction.
