Feeding only 300W to a RMU208

Luis Bejarano ·
Currently facing a situation where I have a PM4500 and must power 3 RMU208 on single channel mono which would give me 300W for each channel since this speaker is 8ohm, I could wire them parallel to lower the resistance to 4ohm on a pair of RMU208 but the client requires Left Right and Center channels independently. Will I loose significant power if I give this speaker only its long term power requirement? Power Handling, long-term continuous Bose extended-lifecycle test⁴: 300 W

Hi Thomas, Thanks for answering so fast, If I understand correctly the PM4500 will provide me with 300w RMS for each mono channel and would be loosing 3dB on each RMU208.

Hi Luis, the power handling numbers in the TDS are stated using a noise signal with 6dB crest factor. In order to achieve this power, you need an amplifier with 600 watts of RMS power. If you can only supply 300 watts, the max SPL numbers from the TDS would have to be reduced by 3dB. Any further questions, let us know. best rgds, Thomas

Powermatch amplifier, remote overload

Luis Bejarano ·
Scenario: Ex1280 + PM8500N controlling 8 zones on 50V high impedance mode. CS Remote 2.2 made layout to control all 8 zones, 5 people share the same remote on their phones (1 iPhone, 4 android) and additionally its installed with remote client 2.2 on 2 windows PC's. Bug: The remote completely stops working, not control or feedback from the volume levels. You can still go online to the amplifier with CSD but the CS remote will show the amplifier as offline. To fix this you have to close all...

Hello Luis, Thank you for reaching out to us. Is it possible for you to share the CSD and CPZ files? Are all devices, including PC, have this issue? When does it happen, like, when all devices are controlling at the same time, in idle after x time, ..... Hope you can provide us more information. BR Arno
