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 M25 can also be remotely switched from Standby to On and vice-

versa using the 12V-trigger input on the back panel. When the M25 is

in the Standby mode, the Standby LED will be amber indicating the

Standby mode. For the 12V-trigger input to work, the M25 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 M25'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 M25 is activated the indicator

LED on the front panel will light.
