Glyph GPM-216

• Musicians connect instruments to the analog inputs, which can accommodate sources such as vocal
mics, instrument mics, direct guitar, keyboard or bass signals. It can also handle the output from a
mixer, or output from guitar/bass amps.
• The "loop through" outputs on the back of the unit are connected to the FOH mixing board. This can
be done through the existing stage snake head. The signals delivered to the FOH console are
unaffected by the GPM-216. It is essentially a cable split.
• Musicians connect the main outputs of the GPM-216 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 GPM-216. Musicians mix local and
incoming sources, and broadcast their own sources onto the network for others to mix. Musicians 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.
About GPM-216 Modes - Setup and Performance
Setup Mode
The front panel has controls for mixing incoming sources to create a personal monitor mix. It also has
controls for programming the unit in advance of the performance. This is called Setup Mode. Setup Mode
allows a user to change parameters that will remain more or less the same during performance. During
setup mode, the GPM-216 does not transmit local sources to the network. Examples of Setup Mode
parameters would be:
• Unit name
• CPU usage
• Save diagnostics info
• Mixer software version
• Source name
• Stereo/mono source transmit
• Source channel number
• Phase reverse (polarity)
• Phantom power
• Network configuration
Performance Mode
Most of the time the GPM-216 will be used in Performance Mode. While in this mode, the user can make
changes to each source while performing. Examples of Performance Mode parameters would be:
• Volume
• Mute
• Solo
• Pan
• Instrument Tuner
