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.
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.
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.
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.
Boost/cut adjustment; ±18 dB in steps of 0.5 dB.
Note: In EQ2 mode, the gain controls are only available on PAGE 4.
