Unpacking
Please read this guide before you start using the GamuT D3. Remove the cables from the carton if
included, and carefully unpack the D3 from the protective plastic packing.
Mains power
The GamuT D3 can be connected to mains power using an IEC mains cable. A more expensive
mains cable may in some cases improve the sound quality.
Switch it on using the switch situated under the bottom plate beneath the front right corner. The
blue light on the front will light up.
Inputs
The GamuT D3 features 5 inputs; 4 phono inputs labelled
MM/MC, Tuner, Tape
, and
HTH
, and
also one XLR input labelled
CD L & R in
on the rear panel. They all have gold-plated RCA/phono
sockets or gold-plated XLR sockets. The input selector switch is not in the signal path; it just feeds
DC to the high-quality NEC relays placed near the input sockets to keep the signal path short.
The input impedance is 20kOhm for the RCA inputs. This works well with most quality signal
sources with a normal output impedance. If a MM/MC option is fitted, the MM/MC RCA input has a
plug-in board with loading resistors, 47kOhm standard.
The XLR input sockets are electronically balanced, with 40kOhm balanced. Both Pin 2 and Pin 3
are 20kOhm referring to Pin 1.
If you have not purchased the optional MM/MC board, this input functions as an auxiliary input for
normal signals.
You can use the balanced input for any balanced signal source such as a CD player or DAC. Your
can also use it with a pair of RCA female/XLR male adapters for unbalanced sources.
Remote control (optional)
The remote volume can always be activated regardless of input. To use the remote to select inputs
and to use the mute function, you must use the left knob on the D3 to select REMOTE.
There are three remote control unit options:
1. GamuT RC1 plastic silver amp/CD-player remote unit (standard from September 2004)
2. GamuT RC2 aluminium silver amp/CD-player remote (optional)
3. Marantz RC3200 programmable remote with touch-screen (optional)
There are two ways of selecting inputs with the Marantz RC3200 remote: You can press AMP, and
then use the left or right cursors to switch between the inputs. Alternatively, you can press the input
button you want twice.
The Marantz RC3200 remote does not have an MM/MC button. Press the VCR button twice
instead, or use the left cursor to step until you reach MM/MC. With Marantz software or directly via
the RC3200 menus, you can customize the buttons to your preferred size, text and number. Please
see the RC3200 user manual for further details.
To adjust the level with the remote, use VOL up and down on the left side of the remote.
Press mute on the remote to mute all inputs, press again to resume play.
