2. When powering up the MM 10AC subwoofer the following startup events occur and are indicated by the Limit LED 1 The LED flashes green and then yellow during power up 2 The LED turns solid green indicating the subwoofer is ready to reproduce audio CAUTION If the Limit LED turns red and stays solid red after powering up and the audio is muted the subwoofer has encountered a failure and may need to be serviced Contact Meyer Sound Technical Support CAUTION If the Limit LED turns solid red and the MM 10AC continues to output audio though at reduced levels the subwoofer s voltage may have dropped below 90 V AC When these con ditions are encountered operation of the subwoofer should cease and its power supply and cabling should be verified Limiting Yellow Limiting activity is indicated when the Limit LED turns yel low When engaged the limiter protects the subwoofer s driver and prevents signal peaks from causing excessive distortion in the subwoofer s amplifier thereby preserving headroom and maintaining smooth frequency responses at high levels When the level returns to normal below the lim iter s threshold the LED turns green and limiting ceases The MM 10AC performs within its acoustical specifications at normal temperatures when the Limit LED is green or if the LED turns yellow for two seconds or less and then returns to green for at least one second If the LED remains yellow for longer than th
