Ouput power :
@600 ohm = 29mW
@300 ohm = 56mW
@150 ohm = 104mW
@64 ohm = 211mW
@32 ohm = 346mW
@16 ohm = 500mW
- Max Output level = 5.3Vrms (for best performance)
- full power bandwidth limit @ Vout - 7vpp and Rload - 500ohm = 12.2 MHz (rhesus) or depends on opamp installed (zenith)
- power consumption : +-150mA
3 gain selectable :
1st gain for input level more than 2vrms (max 2.5Vrms)
2nd gain for input level 1.5vrms
3rd gain for input level less than 1vrms
