An LED meter monitors the master output before the 
zone selection. This signal is also present on the 
headphone connector below the output meter.
The Plena Easy Line Mixer has an input for 24 VDC 
backup power, but has no built in 24 VDC battery 
charger. However, Power Amplifiers from the Plena 
product range have a built in 24 VDC battery charger. 
A separate battery charger is, therefore, not required. 
The charger charges the battery with a 0.5 A constant 
current until the battery voltage reaches 27.4 VDC. The 
charger then switches over to constant voltage charging 
(also known as float charging).
Note
When using the unit with backup power of 24 V, 
make sure that the unit is always powered ON. 
When the unit is switched OFF, the batteries will 
be drained as this will be regarded as a power 
source. Consequently the unit will revert to 24 
VDC power from the 24 V input.
