Using the 3-Band Equalizer (688 only)
The CL-12 adds 3-band EQ to the 688. EQ is only available when sample rate
is 48.048 kHz or less, and it is only available for adjustment when CL-12 is
connected.
• LF is a fi xed 100 Hz EQ by default, with +/- 12 dB gain adjustment. The de-
fault may be altered via settings in the EQ submenu.
• MID provides variable EQ frequency adjustment over 400 Hz – 6k range
with +/- 12 dB gain adjustment.
• HF is a fi xed 10 kHz EQ by default, with +/- 12 dB gain adjustment. The

EQ LEDs
Above the SEL button for each input, the EQ LED illuminates blue when any of
the LF, MID, or HF are set to non-zero gain, giving a quick global indication that
some form of

to the input(s).
If a selected input
has LF applied, the
LF LED illuminates
orange.
If a selected input
has MF applied, the
MID LED illuminates
yellow, and if a
selected input has HF
applied, the HF LED
illuminates green.
