SF-3 Factory-installed SIPs
fHP= 30 Hz (27 kΩ SIP resistor in J2)
fLP= 250 Hz (22 kΩ SIP resistor in J6)
SF-3 Factory Switch Settings
Switches 1 through 6 and Switch 10 OFF: Default setting for SF-3
Switches 7 & 8 ON: Low-pass filter off (“cinema” setting)
Switch 9 OFF: LF flat
When shipped from the factory, the DIP switch settings should be set as follows:
SF-3 Recommended Amplifier Settings
Clip limiters ON (both channels)
High-pass filter OFF (both channels)
Operating mode: Stereo or Bridge mode, as the application requires
