• No power to the amplifier: The amplifier is not plugged into the power receptacle. Make sure power cord is
plugged into a properly working AC power outlet.

• No power to the amplifier: Main fuse is blown.
IMPORtAnt!
Always disconnect unit from the AC Mains before checking AC mains fuse section. The AC Mains fuse,
should not generally blow unless a malfunction has occurred. The fuse must be replaced only with the exact
type and rating of the fuse originally supplied and specified. If the fuse has been replaced but blows again
within a short time, disconnect all power immediately and contact your dealer for support.
• Input signal is not present or is at a very low input level; Check subwoofer level settings at the preamp or
processor.
• Volume control is turned down: turn the SDA-1700 front-mounted volume control clock-wise.
• Crossover control is set too low: Raise the crossover frequency by rotating the crossover control clock-wise.
• Output connections are shorted: Check for shorts in the loudspeaker cables.
• Amplifier is in thermal protection: Refer to the "Cooling Requirements" section of this manual. Look for
ventilation restrictions and/or high ambient temperature.
