Normal use

When you switch on, the blue light in the front will light up to confirm you have mains power on.

One second later two small clicks can be heard from inside the amplifier, they confirm, that the amplifier

has connected the loudspeakers using the output relay.

One second later still, there will be two clicks in the loudspeakers.

These clicks are your confirmation that the protection system have found everything to be OK.

The input signal can now pass through to the loudspeakers.

Each channel has its own protection circuit, so the click from one channel may arrive delayed compared

to the other channel.

DO NOT

Do not switch the amplifier on, then off, then on again quickly. The blue light must disappear

completely, before you switch on again

Only switch on and off using the power switch

Unplugging the mains cables, while they carry current will corrode and damage the surface of the metal

of the mains plugs and sockets. This can cause reduced sound quality and electrical fires.

The mains switches have special metals in the contact points selected for handling high in-rush currents,

as well as to break large currents. Plugs and sockets are not made of such metals.

What you can check if you do not get sound

Is there light on the front panel? If not, have you plugged in the mains cable correctly? Is the fuse

broken? Check both in the plug and on the back panel of the amplifier.

Do you have mains power on? Check the mains socket by plugging in another working unit

Only change a blown fuse once, and use the spare slow blow fuse located in the mains socket on the

back panel of GamuT M250. Use only the special spare fuse in the fuse holder.

For 230-240 Volt Mains use sand-filled 5 Ampere slow blow fuse type marked T5A

For 115-120 Volt Mains use sand-filled 10 Ampere slow blow fuse type marked T10A

If the fuse blows again you must consult your dealer, the amplifier is most likely defective, and it can not

repair it self, so changing fuses many times will not help.

Changing the fuse more than once can increase the repair price, and you can cause a fire or a deadly

electrical shock.

These sand-filled types can break up to 1000 Ampere current, a normal slow blow fuse can only break

35 Ampere, so it may not stop the current!

If you have light on the front panel and only one channel is playing sound, then take its input cable, and

put it into the quiet channel.

If it still is quiet, then unplug the loudspeaker cable from the OK channel, and use it on the quiet channel.

If it still refuses to play sound, it is likely to be defective. Call your dealer.
