ONNECTIONS
Guitar Inputs - The GSP-2101 Artist provides two jacks to choose from when connecting your
guitar. One on the front, and one one the back (see diagrams 2-4 & 2-5 ). They are identical
except that the front input jack takes priority over the rear input jack (i.e. when you use the
front jack, the rear jack becomes inactive). The rear jack is provided for those who "hard-wire"
their equipment into racks and prefer to run their cables behind the equipment instead of the
across the front.

2101 Outputs - The GSP-2101 Artist includes both balanced 1/4" and XLR outputs (see dia-
gram 2-5). The 1/4" outputs are commonly used to feed a guitar amp(s), and the XLRs are usally
connected to a mixing console (in both live and recording studio situations). Be sure to keep
levels low to avoid possible speaker damage when making these audio connections.

1/4" vs. XLR Outputs - These outputs are identical except, the Active Speaker Compensator
circuit only effects the XLR outputs. This allows a player to run an amp set-up on stage, while
simultaneously sending signal to a mixing console using the Active Speaker Compensator.

FX Loop - The GSP-2101 Artist provides a programmable line level mono send/stereo return
FX loop (see diagram 2-5). This allows you to insert additional processing into the 2101's signal
path. The signal leaves the box after the Preamp and EQ circuits, and returns just before the
A/D convertors for the digital processing (see Block Diagram ). Although the A/D converters
usually only receive a mono signal from the analog section, the FX Loop Returns can be used for
either mono (left jack only) or stereo applications (both jacks).

How the FX Loop Return’s signals combine with the original signal can be defined and stored
into each Program, using the following settings:
into each Program, using the following settings:
Bypass - The FX Loop Returns are off, and completely ignored.
Summed - The FX Loop Returns are summed together with the original signal using a
50:50 ratio.
No Sum - If plugs are connected to the FX Loop Return jack(s), they are the primary
signal source. If there is no signal present at these jacks, you don't hear anything from
the GSP-2101 Artist. When the jacks aren't used, No Sum behaves the same as the FX
Loop Bypass setting.

Every Program in the 2101 has the FX Loop set to bypass, so you will need to turn the loop on in
each Program that requires the external processing. See Editing Effects on pg. 13 for information
concerning parameter editing.

Active Speaker Compensator- The GSP-2101 Artist includes special circuitry before the XLR
and Headphone outputs that simulates the sound of microphoned guitar cabinets. The Active
Speaker Compensator is engaged when the button next to the XLR out jacks is pressed in. This
circuit is extremely useful for recording studio applications, or connecting the 2101 directly to
the mixing console in live applications. Guitar speakers are not flat, full frequency transducers.
The Active Speaker Compensator simulates the frequency response and behavior of a common
4 x 12 Cabinet, giving you true guitar speaker sound without extra baggage!

Phantom Power - The GSP-2101 Artist has no need for Phantom Power supplied by mixing
consoles. If your console doesn't allow you turn off Phantom Power to individual channels, don't
worry, the 2101 will survive. However, with all equipment exposed to Phantom Power, you
should always engage the Phantom Power AFTER all audio connections are completed.
