EQ Compressor

The EQ Compressor algorithm is a multi-featured parametric equalizer coupled with a dynamic, intuitive compressor, offering a premium tone shaping tool for a variety of instrumentation.

The EQ section includes two completely parametric bands along with low shelf and high shelf filters for easy manipulation of your tone (be sure to check out the graphical EQ curve in H9 Control).

The unique compressor section can be placed before or after the EQ for maximum flexibility with a single control, enabling you to emphasise, harness, and control the parts of your sound you want to shine through a mix. EQ Compressor also features up to 12 dB of boost at the output to push an amp to awesomeness for your soul tearing solos

Requirements:

All H9 algorithms require an H9 stompbox to function.
To demo or purchase any algorithm, please download the the H9 Control app.

Important: To have access to all algorithms and functionality, please make sure to download the latest version of H9 Control and also update the firmware on your H9(s). Click here for Update Instructions.

EQ Compressor Algorithm Controls
Gain 1 [GAIN1]
The gain of the first parametric filter. Provides 12dB of boost or 18dB of attenuation.
Frequency 1 [FREQ1]
The center frequency of the first parametric filter. The frequency ranges from 30Hz to 1500Hz.
Width 1 [WIDTH1]
Controls the bandwidth of the 1st parametric filter. A value of 10 represents a larger bandwidth while a value of 1 represents a narrower bandwidth.
Gain 2 [GAIN2]
The gain for the 2nd parametric filter. Provides 12dB of boost or 18dB of attenuation.
Frequency 2 [FREQ2]
The center frequency of the first parametric band. The frequency ranges from 1000Hz to 9999Hz.
Width 2 [WIDTH2]
Controls the bandwidth of the 2nd parametric filter. A value of 10 represents a larger bandwidth while a value of 1 represents a narrower bandwidth.
Bass [BASS]
Controls the gain on the Low Frequency Shelving Filter which is centered around 400Hz with a slope of 8dB/Octave. You can boost the lows by 12 dB or cut by 12dB.
Treble [TREBLE]
The gain on the High Frequency Shelving Filter which is centered around 1800Hz with a slope of 8dB/Octave. You can boost the highs by 12 dB or cut by 12dB.
Compressor [COMP]
The amount of compression applied to the signal. The values to the left half of the knob will affect the Pre - EQ compression, increasing the amount of compression as you move it counter clockwise. The values to the right half of the knob will affect the Post -EQ compression, increasing the amount of compression as you move it clockwise. The compressor is specially designed to vary the numerous parameters of a typical compressor such as the ratio, attack, release and the makeup gain to keep the overall loudness consistent.
Trim [TRIM]
Controls the level at the output of the signal path. Provides 12dB of boost or 12dB of attenuation. The algorithm is designed to “gracefully” clip if there is too much gain inside the EQ. The red overload LED on the H9 Pedal will light up in this case.
Output Level
At 0 the output level is unaffected. Increase the output level of the effect by up to 20 dB or lower by 30 dB.
TEMPO ON / TEMPO OFF
Tempo is turned ON/OFF on the H9 by simultaneously pressing the Right Footswitch and the PRESETS button. With Tempo OFF, tapping can be used to adjust delay parameter values (displayed as milliseconds or Hz). With Tempo ON, tempo is in BPM.
Active
Turn effect on or off..
HotSwitch
The Middle Footswitch can be programmed to act on the loaded Preset as a programmable controller allowing the user to switch between the normal Preset parameter values and a programmed, alternate set of parameter values. It’s like having two Presets in one.
TAP
If Tempo is ON, the display indicates the current tempo in BPM (30 to 500 BPM) while tapping and the Tap LED will blink at the BPM rate. If Tempo is OFF, the display indicates the parameter value (milliseconds for most algorithms).
