NAD T975 Power Switch/Standby Led, Protection Led, Soft Clipping Light, Front Panel Controls

FRONT PANEL CONTROLS

1. POWER SWITCH/STANDBY LED

Press this button to switch the amplifier on or off. The Power LED located just above the power button and Protection LEDs (see Protection LED below) will light up. After a few seconds, the Protection LEDs will switch from red to blue, indicating that the amplifier is ready for use.

The T975 can also be remotely switched from Standby to On and vice- versa using the 12V-trigger input on the back panel. When the T975 is in the Standby mode, the Standby LED will be amber indicating the Standby mode. For the 12V-trigger input to work, the T975 must first be turned on by means of the front panel Power Switch, and the switch must be left in this position. Using the 12V-trigger source component, switch its 12V-trigger output to on and off. The T975's trigger input will now follow the source component's 12V-trigger output. Ensure that the Auto Trigger switch on the back panel is in the ON position and that the 12V-trigger input is connected properly.

2. PROTECTION LED

The Protection LEDs turn red for about 3 seconds, every time the amplifier is switched on. After a few seconds they will turn blue and the amplifier is ready for operation.

These LEDs turn red when one or more of the internal seven amplifiers go into protect mode, but the other amplifiers will continue to function as shown by their blue LEDs so it is likely you will still hear sound.

When the amplifier is switched off from normal operation by means of the front panel power switch, or to Standby via the rear panel trigger source, the Protection LEDs will light up red and will fade out in a couple of seconds..

NOTE: If you see a Protection LED turn red, turn off the amplifier immediately using the front panel Power Switch. Check if all speaker wires are connected correctly and that none of the wires are damaged, causing a short circuit. Another cause may be excessive heat build-up inside the amplifier. Make sure there is adequate ventilation around the amplifier and that none of its ventilation slots, top or bottom, are blocked. After the amplifier has cooled down it will function normally again.

In case one or more of the Protection LEDs remains red despite the checks mentioned above, turn the amplifier off by means of the front panel Power Switch and consult your NAD dealer.

3. SOFT CLIPPING LIGHT

When the Soft Clipping circuit of the T975 is activated the indicator LED on the front panel will light.
