Unpacking; Connecting The Input Cables; Warming Up - Gamut D200i User Manual

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.
