Gamut D200i - Initial Setup and Connections; Unpacking the Amplifier; Connecting Input Cables; Amplifier Warming Up Period

Unpacking
Open the inner box, remove the 2 top blue foam parts
Lift the amplier up and place it on its feet. Be careful not to damage the gold plated connectors
on the rear panel. Keep the box and the blue foam, it is specially made to protect the amplier well,
and you may need it some day, when you move or if you want to upgrade the amplier.
Connecting the input cables
The main inputs are the two 3-pin XLR sockets. They are electronically balanced, and they will
therefore reduce hum pickup in the input cables. So the best choice of cable is a balanced
XLR cable, coming from a balanced output on your preamplier.
In case you have a preamplier with only RCA outputs, you can use the RCA inputs. Remember to
plug in the two XLR Terminator plugs, when you use the RCA inputs. They connect the negative
input to ground, making sure that the input is not “oating” with the risk of noise or oscilliation
comming in to the amplier circuits.
You release the XLR connector by pressing on the release button next to the XLR socket, and
pulling the XLR plug out at the same time. Do not pull on the cable, only on the plug.
The XLR connector: always connect Pin 1 (the ground) rst and disconnect it last. This way,
XLR connectors can be plugged and unplugged while the amplier is switched on.
However, some DC from the preamplier may still cause loud clicks, so it is recommended to
wait 10 seconds and then switch the power amplier on as the last precaution. If you use a tube
preamplier, please wait several minutes the rst time you use it. Always switch o the power
amplier rst before switching o your preamplier or any source. Always remember to turn down
the volume before switching on of o the poweramplier, if you fail to do so, the output relays
will ware down faster.
DO NOT CONNECT LOUDSPEAKER WIRES OR OTHER HIGH VOLTAGE CABLE TO THE INPUTS.
Warming up
The GamuT power amplier will play sound a few seconds after you turn it on. However, please
allow minimum 30 minutes before you start serious listening, as the sound quality will slowly
improve, because all the parts need to reach their optimum operating temperature.
You may also note a slight improvement in the rst months of use. This is caused by the
capacitors, which do improve with use.
A CD player in repeat mode can speed up the process while you are not at home.
Do not play too loud.
After this break-in period is over, simply switch the GamuT on when you get home, and it will be
ready to perform at its best after dinner.
