This system provides background music and paging for 2 primary zones in a restaurant, bar, or retail store, using these requirements:
This can be accomplished with:
All of the DSP required for paging, distributed background music selection, stereo to mono mix, equalization, and Level control is included in the HAL3s. Each of the six outputs drives one speaker, so each output has a limiter. Three Zone Processors are used in Halogen: one for the Bar Left channel, one for the Bar Right channel, and one for the Restaurant and Restrooms Mono channel. 3-band tone controls are provided for each of these areas. The DR3 Level controls are linked to both left and right Zone Processor levels.
The manager has access to source and volume controls from the web browser in a laptop, tablet or smartphone. The additional restroom zone volumes can be adjusted here without the expense of another wall remote control.
Alternative System #1: An all-mono system with 3 audio inputs. This could eliminate the need for the RAD6 depending on equipment placement. Mono operation would remove one Zone Processor in Halogen. The Line-Plus Inputs can make a mono signal into the HAL3s using the unbalanced left and right signals from consumer audio equipment (RCA connections).
Alternative System #2: Two more zones. There are two leftover HAL3s outputs that can provide future expansion (line outputs 5 and 6). Additional zones can be created for the kitchen, an outdoor patio, or subwoofers in the bar. The subwoofers would require inserting 2-way crossovers in the processing map, a very easy process.
The system has two stereo source inputs:
