18 GR2 User Guide
Application Example 1 – Two Room Bar or Restaurant
Here, stereo zone 1 feeds the lounge, the area used for several activities
including background music, customer jukebox play, big screen TV or video,
and live entertainment such as solo or duo musicians, karaoke, comedy or
quiz night. Mono zone 2 provides background music to the restaurant, or can be
switched to follow the entertainment in the lounge particularly if a big event
combines both rooms into one. Paging announcements can be made to either
or both zones, for example calling a party to their table. The 6 mic/line channels
cater for the dedicated paging mic, an MC and two live performance mics, while
inputs 4 and 5 are configured as an additional music source, in this case the
remote karaoke machine. This provides a 4 mic / 4 stereo music source system.
Mic 1 is used for paging. Mic priority works with the MC mic 2 providing a
means of turning off the two performance mics, for example during quiz night.
The aux output is used to drive a sub bass speaker in the lounge. It is
configured with a mono mix of the zone 1 music selection and routed through
the built-in 100Hz crossover. The fire alarm provides a switch to mute the music,
and keep the paging channel live. The GR2 can also accept a pre-recorded
evacuation message. Wall plates provide local level and source selection control
in both zones. The choice of Phoenix screw terminal or standard audio
connectors is an advantage here. For a small, quick installation it may be more
convenient to use standard cables to connect the sources and amps using RCA
phono, and a paging mic using a standard XLR lead.
The configuration switch settings for this example are shown below. In this
case, the mic priority function is enabled, mic 1 used for paging enabled to both
zones, music 4 source configured, music 1 priority selected for the jukebox in
zone 1 with long release time active, remote wall plate control for each zone,
music plus mics selected for performance zone 1, music only for BGM to zone
2, and the aux output set to follow zone 1 with filter for the sub bass speaker.
