Specifications 

 
Specifications are for units in Dual Mode driving both channels into 8-
ohm loads, (26 dB = 20 times voltage gain) and operating from 120 
VAC, unless otherwise specified.  
 

“Standard 1 kHz Power" refers to maximum average power in watts at 
1 kHz with 0.1% THD. 

“Full Bandwidth Power" refers to maximum average power in watts 
from 20 Hz to 20 kHz with 0.1% THD.
