Introduction
About the GPM-216™
Congratulations on your purchase of the GPM-216. When performing, the GPM-216 will improve the way
you hear yourself and other musicians. Plug your instruments and microphones into the front-panel audio
inputs, and the audio is digitized. It is distributed as audio data streams over a network using standard
Ethernet cables. The unit has an easy to use interface to control your individual mix of local and networked
audio sources using front panel controls and an LCD screen. It has front-panel output connectors for
headphones or earbuds, and line outs on the back for powered wedges or other audio gear. Send/Return
loops allow musicians to patch in external effects or EQ for their overall mix, or apply them to their own
input channels.
The GPM-216 enables bands to have a private, peer-to-peer (or, more accurately, musician-to-musician)
network, independent from the house sound system. Each musician creates their own individual monitor
mix exactly the way they want it. The GPM-216 provides a way for musicians to mix and monitor network
signals on a rack-mountable piece of hardware through earbuds, headphones or speakers.
Peer-to-Peer/Musician-to-Musician Monitoring Architecture
Using the Glyph Monitor system on stage is dramatically different than using a traditional monitoring
setup because it does not require a dedicated monitor mixing board or engineer. Its design implements a
peer-to-peer architecture, where all the units connect to one another, instead of connecting to a central
mixer. Signals from performers are split at each performer's unit, sending to both the monitoring network
and the front of house (FOH) mixing board. Each performer’s unit contains the basic functions of a mixing
board (mic pre, gain, volume, pan, mute, phase reverse).
