Powered Subwoofer ARC SUB 8 2 WARRANTY IMPORTANT SERVICE NOTES: When testing the ARC Series amplifier, a load must always be connected to the output terminals , whether the woofer, or a 4 to 8 ohm resis- tive load. All AC powered test instruments (meters, oscilloscopes, etc.) must have a floating ground, i.e. be connected to an isolation transformer.
