The GPM-216 lets musicians create their own individual monitor mix, exactly
the way they want it, on stage or in the studio. Musicians plug instruments and
microphones into the front-panel audio inputs, where the signals are digitized
and distributed to other units 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.
Peer-to-peer/musician-to-musician 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 GPM, 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), eliminating the need for a monitor
mixing board.

Cool, huh?

GPM-216 in a live sound environment
Each musician carries a GPM-216 with them to the
gig and sets it up with their gear on stage. The unit
acts as a console for mixing each musician’s
monitor. Here’s how it’s connected:
• Musicians connect instruments to the front-panel
analog inputs, which can accommodate sources
such as vocal mics, instrument mics, direct guitar,
keyboard or bass signals.
• “Loop through” outputs are connected to the
FOH mixing board. The signals delivered to the
FOH console are unaffected by the GPM-216. It is
essentially a cable split.
• Musicians connect the main outputs to their
monitor of choice, which could be headphones,
earbuds or amplifiers driving traditional wedges.
• GPM-216 units are connected together via
standard CAT5 Ethernet cable through an
Ethernet 100 switch.
Signals from everyone in the band are seen as
"inputs" on every unit. Musicians mix local and
incoming sources, and broadcast their own sources
onto the network for others to mix. Musicians
simply select a source via a front panel selector
button, and can quickly change volume, pan, mute
and solo for that source. It is designed for easy
readout with an LCD screen for identifying names
of sources, placement in the stereo spectrum and
status of mute or solo. All of the controls and the
screen are well lit for stage use.
