6 channell system

I created a system with 6 Up2stream pro for a restaurant and provided sound for 6 different environments, all via wifi. The manager is very satisfied with the result: from a smartphone he is able to define what to play and where, having a flexible solution capable of grouping rooms and playing from different sources.

When you make the right adjustments, you achieve exceptional quality for the price

2.1 Plate Amp.

Sound quality
Easy to install and use.
Easy to setup speaker and room compensation with ACP Workbench.
Plenty of power/volume.

4Stream app can't search NAS to populate playlist - only searches local storage.

ACP Workstation - USB cable has to be disconnected to hear effects of changes.

Plate amp with active 2/3 way crossover (2CH).
This would allow most speakers to be upgraded.
