Hi Garry,
You would need the PA270 at the very least. Are the speakers limited to a minimum wattage tap of 75?

When sizing amps for distributed 70v systems, the amp wattage must be at least the sum of the utilized taps at the speaker. Safely, it should be the sum of the max tap of all speakers connected. In your case, 6 x 75w = 450 watt amp or risk damaging the amp if clipped. Keith • 12/17/2019, 2:17:43 PM What are the dimensions of the unit?

Customer Service • 12/17/2019, 2:17:43 PM
Hi Nick:
We have three 70 Volt Amp/Pre-amp/Mixers...
The PA 270; 240 watts, PA 150; 120 Watts and PA 90 is 60 watts.
To calculate the wattage you are looking for you multiple the speakers by the tap setting you select on the speakers.
20 speakers x 10 watts = 200 watts + 20% (200 x 20% = 40) = 240 watts.
This is a link to a handy calculator:

The PA 270 would work perfect for these 20 speakers set to 10 watts. Note you do not need to set all speakers at the same value. You could set 4 of the speakers to 15 watts (to play louder in comparison to those set at 10 watts) and set 4 others to 5 watts to balance out the system. These will at a lower level compared to the 10 watt and of course the 15 watt speakers. The rule of thumb is the total wattage of the speakers should be a maximum of 80% of the available wattage from the amplifier. You can also daisy chain our PA series amp/mixers for higher total power.
So the PA 270 work for you at with each speaker set at 10 watts. The PA 150 would work for your 20 speakers at 5 watt power tap per each.
Also checkout our 70V MVC Mono 70 Watt Volume controls (100, 50 and 25 Watt) with unique Pass through capability for daisy chain installation.
