Part 6: Editing Effects

[50]— EQ (CONFIGURATIONS 4 AND 5 ONLY)

The stereo shelving EQ provides bass and treble boost to the entire output of the QS — not just the Effect Sends — and is only available in Configuration 4 (Reverb+EQ) and Configuration 5 (Overdrive+Lezlie). So if you push the EQ button while in Configurations 1, 2, or 3, you’ll get the message “NOT IN CONFIG”.

There are four EQ parameters:

1)Low Frequency (range: 30Hz to 180Hz)

2)Low Frequency Gain (0dB to +12dB)

3)High Frequency (3kHz to 10kHz)

4)High Frequency Boost (0dB to +9dB).

LO EQ FREQUENCY

Range of Settings: 30Hz to 180Hz Page 1

This parameter determines the cutoff frequency of the Lo EQ. Changing it will have no audible effect unless Lo EQ Gain (see below) is set above 0dB. When that happens, then all frequencies below and including this selection will be boosted.

LO EQ GAIN

Range of Settings: 0dB to +12dB Page 2

This parameter controls the amount of boost that will be applied to the frequencies selected by the Lo EQ Frequency setting (see just above).

HI EQ FREQUENCY

Range of Settings: 3kHz to 10kHz Page 3

This control adjusts the cutoff frequency of the Hi EQ. Changing it will have no audible effect unless Hi EQ Gain (see just below) is set above 0dB. When that happens, then all frequencies above and including this selection will be boosted.

HI EQ GAIN

Range of Settings: 0dB to +9dB Page 4

This determines how much boost will be applied to the range of frequencies selected by the Hi EQ Frequency parameter (see just above).
