EQ2 Mode: Each page will contain the same EQ parameter for all four bands. For ex-
ample, Page 2 will contain the frequency controls for all four bands. As
with EQ1 mode, there are three parameters: Q (bandwidth), center fre-
quency (in Hz), Gain (in dB), as well as ON/OFF selection of the particu-
lar band.
EQ BAND ON/OFF: The SW keys on Pages 1, 2, and 4 control the ON/OFF function for the
selected band. The band is active when these keys are illuminated.
Last used Frequency (Page 1): On Page 1, the last used frequencies of all four bands are displayed. In
addition, each band can be switched ON/OFF with its SW key.
FREQUENCY (Page 2): Center frequency (or, if SHLV is selected for the low or high frequency
band: turnover frequency) adjustment:
• EQHI: 20 Hz through 20 kHz, in 120 steps;
• EQHM; 20 Hz through 20 kHz, in 120 steps;
• EQLM; 20 Hz through 20 kHz, in 120 steps;
• EQLO; 20 Hz through 20 kHz. in 120 steps;
Note: In EQ2 mode, the last used frequency is displayed on PAGE 1. Adjustment
of the frequency controls is available on PAGE 2.
Q (Page 3): The Q (bandwidth) can be set to several discrete values. In addition, for
the low- and high-frequency bands, a shelving-type filter can be selected.
• EQHI, high-frequency: SHLV (shelving-type), or Q = 0.27 through
8.7, in 30 steps. The SW key is illuminated when in SHLV mode.
• EQHM, high-/mid-frequency: Q = 0.27 through 8.7, in 30 steps,
• EQLM, low-/mid-frequency: Q = 0.27 through 8.7, in 30 steps,
• EQLO, low-frequency: SHLV (shelving-type), or Q = 0.27 through
8.7, in 30 steps. The SW key is illuminated when in SHLV mode.
Notes: In EQ2 mode, the Q controls are only available on PAGE 3.
For EQHM and EQLM bands, Q can be selected between “constant-Q”
(ConQ) and “constant-range” (ConR) filter types, whereas for the EQHI
and EQLO bands, “shelving” (SHLV) or “constant-Q” can be selected.
The SW keys are illuminated when the bands are in constant-range or
shelving modes, respectively.
GAIN (Page 4): Boost/cut adjustment; ±18 dB in steps of 0.5 dB.
Note: In EQ2 mode, the gain controls are only available on PAGE 4.
