H9 User Guide Setting Levels

Setting Levels

The H9’s input and output levels can be adjusted to optimize performance in most setups but inputs are optimized for instrument level. There are some important distinctions between setting input and output levels.

Input level is adjusted for best audio performance. For example, the H9 may be connected to a guitar with low level pickups and the guitar signal will not be ‘hot’ enough and the H9 will sound noisy. In this case you’ll want to increase the H9’s input level (input gain).

It’s important to note that if you add gain with the input level control, the output gain will be automatically cut to preserve unity gain through the stompbox.

Output level is a bit of a different story. It is sometimes desirable to adjust the level of a given

Effect/Preset. For example, an effect like Rotary can have wide swells of amplitude and, depending on a given Preset’s parameter settings, you may find it too quiet or too loud. This is a consequence of the effect and not a question of level matching to best fit in a setup. For this reason, Output Level settings can be tweaked and saved with the Preset.

Setting Output Level

To set output level:

Press and hold the Left Footswitch - the Preset will now be Active.

After holding for 2 seconds, the display will show [OUT+0] (default value).

Continue holding the Left Footswitch while turning the Knob to adjust output level from -12 dB [OUT-12] to +12 dB [OUT+12] in 1 dB increments.

Release the Footswitch - the Preset will return to its previous Active or Bypassed state.

Note: Preset output levels must be saved even if there are no other changes to the preset or the output level will revert to its previous setting the next time the Preset is loaded. In other words, if you want the adjusted output level to ‘stick’, you must re-save the Preset.

Setting Input Level/Peak and Signal LEDs

Adjust the H9’s input level for best audio performance. The red Peak LED indicates that the input signal level is close to clipping. Occasional flashing is OK. If the Peak LED is lit solidly, reduce the input level either by reducing the signal level fed to the H9 or by setting the H9’s input gain to a lower value. The green Signal Present LED shows signal present (40dB below clipping). Input Level is the same for all presets, and is found on the System Menu.

Press and hold the HOTKNOB button and Right Footswitch simultaneously for a few seconds to enter System Mode.

Turn the Knob until [UTILITY] is displayed.

Momentarily press the HOTKNOB button.

Turn the Knob until [INGAIN] is displayed.

Momentarily press the HOTKNOB button.

Turn the Knob to adjust the gain between 0dB and +18dB.

Press and hold the HOTKNOB button and Right Footswitch simultaneously for a few seconds to exit System Mode.

Input and Output Swell

The expression pedal can be used to give a volume swell, either before or after the effect.

This can be enabled either globally, meaning it is active all the time, or on a preset by preset basis. You might want to use it before the effect to disconnect or reduce the input, and listen to the effect die away, whereas after the effect it can be used as a volume control or to perform fadeouts. This swell is normally used for expression purposes, and only reduces the volume - it does not boost it.

You may want to disable any pedal or HOTKNOB parameter settings if you are using swell.

This will be done automatically if using Global Swell.

To set the Swell value globally, see System Mode. If a Global Swell is active, the option of selecting it for presets will not be available.

Note that in Pre/Post and Wet/Dry Routing modes, Swell only affects the Wet channel.

Input and Output Swell are not active when the unit is Bypassed. The Swell values are reset to maximum when a new preset is loaded.

Enabling/disabling Input Swell

Press and hold the Left Footswitch as described above. The display will show the

Output Level.

Press the HOTKNOB once. The display will show ISW.OFF (default) or ISW.ON.

Turn the Knob to set it to ON or OFF as desired.

Release the Footswitch - the Preset will return to its previous Active or Bypassed state.

Remember to save the preset, or the change will be lost.

Enabling/disabling Output Swell

Press and hold the Left Footswitch as described above. The display will show the

Output Level.

Press the encoder until the display shows OSW.OFF (default) or OSW.ON.

Turn the encoder to set it to ON or OFF as desired.

Release the Footswitch - the Preset will return to its previous Active or Bypassed state.

Remember to save the preset, or the change will be lost.
