❍ This is defeated automatically when you switch screens in the display. (→ p. 170)
❍ Could you have specified a fade time? (→ p. 143)
❍ This can be adjusted in the MISC SETUP screen. (→ p. 217)
❍ 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.
❍ 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?
❍ Refer to LS9 Editor installation guide on our web site.

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