Burger King

The assignment

Since their design dictates to keep technical stuff out of sight, we need to keep a low profile in Burger King restaurants.

It's also quite straightforward, serving the same music at different volumes to two zones: one for the patrons in the restaurant and one for the employees in the kitchen.

The solution

This calls for in-ceiling speakers and a bare-bones distribution system. Music enters the bus using the tiny EAS-MTX-A dual RCA input module, and since we can run the music in mono in these types of setups, a single amplifier can do the rest.

The lone EAS-AMP-250D is set to dual-mono using the EAS Admin control software, connecting all speakers in the restaurant to what used to be the left channel and those in the kitchen to the right.

We now effectively have two audio zones. To get two volume zones as well, we simply assign a volume group to each of the two amplifier channels.

All that's left is to assign these two volume zones to two strips on an EAS-FX-V3 control panel. This minimalist in-wall touch surface lets employees adjust or mute the volume while withstanding the wear and tear from salt, grease, and ketchup. Probably.

Benefits

While being a simple setup, technically speaking, let's not forget the primary reason for choosing an EAS system: the sound. In between mouthfuls, guests can carry on conversations without competing with lousy audio, enjoying the sweet vibe of pleasant background music.

And while being a beautiful-sounding setup, audio-wise, let's not forget the other reasons for choosing an EAS system: it's cost-effective, quick to install, and simple to use.
