Channel Pair LED Indicators
The
CHANNEL PAIR LED | STATUS |
OFF | The channel pair is OFF. |
|
|
Solid Green | The channel pair is active and operating normally. |
|
|
Fast Red Blinking | Indicates a possible short circuit or low impedance condition. |
(Three Times Per Second) | Speaker wire strands that are touching at the speaker or the ampli- |
| fier's speaker terminals and/or a damaged speaker wire can cause |
| a short circuit. More than three pairs of 8 ohm speakers attached |
| to the same amplifier channel present the amplifier channel with a |
| low impedance. Both of these conditions will cause the LED indi- |
| cator to blink red very quickly. Eliminating the short circuit or con- |
| necting a proper speaker impedance load will enable the channel |
| pair to resume normal operation. |
|
|
Slow Red Blinking | Indicates the channel pair is overheating due to inadequate |
(Once Every Three Seconds) | ventilation. Providing proper airflow to the amplifier will |
| eliminate this problem (refer to page 15, figures 11 and 12 for |
| amplifier placement details). |
|
|
Solid Red | There is a damaged internal component in this channel pair |
| module. The amplifier should be returned to Niles for service. |
