3.4. Pre/Post¶
If your guitar amp has an effects loop, it is sometimes desirable to put certain effects such as drive or compression before the preamp, and other effects such as delay and reverb after the preamp. This can be referred to as a Pre/Post setup, or the four-cable method (4CM).
Pre/Post Mode allows you to setup a variety of Presets at the Pre or Post position of your amp’s signal path.
Fig. 3.6 A Pre-post or 4-cable method guitar amp configuration.¶
Set your H9’s Global Routing Configuration to use Pre/Post from the System Menu.
Connect your guitar to H9 Input 1.
Connect H9 Output 1 to your guitar amp’s preamp input.
Connect your guitar amp’s effects send to H9 Input 2.
Connect H9 Output 2 to your guitar amp’s effects return.
Use Select Mode and Load a Preset to be used for the Pre Path, such as the Aggravate Algorithm.
Press the Parameters Button and turn the Big Knob until you locate the Routing Parameter in the General parameters. Set this parameter to “Pre”, and save the Preset.

Load another Preset to be used for the Post Path, such as the Digital Delay Algorithm.
Press the Parameters Button and turn the Big Knob until you locate the Routing Parameter in the General parameters. Set this parameter to “Post”, and save the Preset.

When you load either of these Presets, the Aggravate Preset will be output to the Pre Path, and the Digital Delay Preset will be output to the Post Path.
