5. Connecting and Powering the Unit
WARNING: All connections between the
MARLEY MKII
and other equipment must be
made when all units are turned off and completely powered down or unplugged.
Failing to do so may cause damage to the
MARLEY MKII
and/or other units.
Please refer to chapter 3, “Back Panel”.
Connect the analogue sources to the inputs (Figure 2, 10-11). The Bluetooth
®
connection
for control will be done after powering the unit.
If you want to use the
MARLEY MKII
as a preamplifier, connect the preamp outputs (Figure 2,
8) to the inputs of a power amplifier; otherwise connect the tape outputs (Figure 2, 9) to a
pair of inputs on an integrated amplifier or preamplifier.
Connect the trigger output (Figure 2, 16) of the
MARLEY MKII
to the trigger input of any
device accepting 12V
DC
which you want to power subsequently to the
MARLEY MKII
turn-on.
Connect the trigger input (Figure 2, 17) of the
MARLEY MKII
to the trigger output of any
device providing 5V
DC
to 12V
DC
which you want the
MARLEY MKII
to turn-on.
Connect the plug from the stock wall wart or from the
Van Der Graaf M
k
II
to the
MARLEY MKII
power input (Figure 2, 15) or from the
Van Der Graaf M
k
II
to the
MARLEY MKII
external power
input (Figure 2, 14).
Connect the wall wart or the
Van Der Graaf M
k
II
to a mains outlet. Both will automatically
accept any voltage from 90V
AC
to 265V
AC
.
Switch the
MARLEY MKII
on by pushing the front panel button (Figure 1, 7). If you’re using
the
Van Der Graaf M
k
II
, and you have set the power mode switch (Figure 2, 13) for
immediate operation, then the
MARLEY MKII
will switch on when activating the
Van Der
Graaf M
k
II
. Please see paragraph 7.5 for details.
NOTE: whenever the
MARLEY MKII
is used as a preamplifier, it is a good habit to switch
the power amplifier on after switching the
MARLEY MKII
on, and to switch the power
amplifier off before switching the
MARLEY MKII
off. This may be accomplished by
using the
MARLEY MKII
trigger output.
NOTE: it is possible to use a dedicated low noise power supply in place of the wall
wart, to increase the sonic performance M2Tech provides a device for this purpose,
the
Van Der Graaf M
k
II
. Should the user opt for use of a non-M2Tech power supply,
M2Tech reserves the right to void the
MARLEY MKII
warranty
