A Lifetime Of Enjoyment; Normal Use; What You Can Check If There Is No Sound - Gamut D200i User Manual

A lifetime of enjoyment

So far, our oldest ampli ers from 1982 still work in professional recording studios, often doing
their job 16 or 24 hours a day. So we expect our GamuT ampli ers to do likewise.
A more likely cause for change would be your wish to upgrade in some years time. Here our
modular approach serves to keep the upgrade cost low, and you avoid sell¬ing with a loss on
the second hand market.
The cabinet should last a lifetime, and the GamuT Logo is engraved down into the surface; wearing
the text out will be quite di cult.
Apart from being good economy, this long term approach is also better for the environment.
Most parts of the cabinet are made of aluminium, which is easy to recycle.
All parts are screwed together to enable easy disassembly. Your grandchildren will be pleased
with your choice.

Normal use

When you switch on, the blue light in the front will light up to con rm you have mains power on.
One second later two small clicks can be heard from inside the ampli er, they con rm, that the
ampli er has connected the loudspeakers using the output relay.
One second later still, there will be two clicks in the loudspeakers.
These clicks are your con rmation 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.
What you can check if you there is no 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 ampli er.
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 D200. Use only the special spare fuse in the fuse holder.
For 230-240 Volt Mains use sand lled 6.3 Ampere slow blow fuse type marked T6.3AH
For 115-120 Volt Mains use sand lled 10 Ampere slow blow fuse type marked T10AH
If the fuse blows again you must consult your dealer, the ampli er is most likely defective, and it
can not repair it self, so changing fuses many times will not help, it could even make things worse!
