Send Bypass The SendBypass parameter allows you to set the bypass behavior of the pre- gain path (everything between the Guitar Input and the Insert Send jack) when the front panel Bypass button is pressed. The choices are:

Disabled: Bypass has no effect on the pre-gain path.

Bypass: An internal relay bypasses the pre-gain path with an analog "straight wire" between the Guitar Input and the Send jack. (This is the default setting.)

Insert Mute: Bypass bypasses the pre-gain path with an analog "straight wire" between the Guitar Input and the Send jack.

Insert Mute mutes the pre-gain path after the Send and bypasses the Insert Return jacks. This allows the Insert button to be used as a preamp bypass when the MPX G2 is connected to a guitar amp input and its effects loop.

Insert For maximum flexibility when connecting other gear to the G2 via the Insert Send and Return jacks, three Insert Modes are provided: FX Loop, Mix and Parallel.

FX Loop allows gear to be connected in series between the pre-gain and post- gain paths. This is the most useful setting when the MPX G2 is used with a guitar amp that has an effects loop, when an external processor is connected to the MPX G2, or whenthe MPX G2 is used as a stand alone preamp with effects. This is the default setting.

In this mode, signals inserted into the MPX G2 rear panel Return jack(s) are passed through a level control, a selectable analog speaker simulator, and then routed (via 24-bit A/D converters) into the post-gain DSP path. In the MPX G2 Effect Order or Routing Map display (Edit mode), the return signal is inserted immediately after the Gain block (G in the display).

Mix mode allows the return jacks to be used as an analog line mixer. This mode is provided for applications when you want to have additional, unprocessed audio mixed with the outputs of the MPX G2. For example, you would use this mode to Insert the output of a CD or DAT player so you can play along with headphones. Signals inserted into the MPX G2 rear panel Return jack(s) pass through the level control and are mixed with the main and headphone outputs of the MPX G2. Note that when this mode is selected, the Return signals are not processed by the MPX G2.

Parallel mode allows gear to be connected in parallel between the pre- and post- gain paths. Use this mode if you want to convert a serial guitar amp effects loop into a parallel loop. The parallel signal path provided by this mode allows the dry analog guitar signal to pass directly to the power amp without running through any converters. Note that when using a parallel effects loop, the Post: Mix parameter (Edit mode) should be set to 100% wet. Signals inserted into the MPX G2 rear panel Return jack(s) are passed through the level control and selectable speaker simulator, then split in parallel — through the post-gain DSP path and mixed with the main and headphone outputs.
