Music is a “Dynamic and Transient” condi-
tion and the power requirements fluctuate 
up and down over time with the audio sig-
nal. Therefore, under most listening condi-
tions the 15Amp/120 Volt version will be all 
that is required for the majority of domes-
tic audio/video systems. 
 
If more power is required, then a 14B - 20 
Amp version is also available. You must 
have a minimum of 12 Gauge household 
electrical wire and a dedicated 20 Amp 
wall plug in order to utilize this feature. 
The other option available is to wire for a 
240 Volt 10 Amp service and use the 230 
Volt 10 Amp European model. 
Maximum continuous output power with both channels driven can only be realized 
on a 120 Volt 20 Amp or 230 Volt 10 Amp version of the 14B ST 
Note: Continuous 2 channel power is limited by specific circuit breaker limitations.
