Operating
At the front plate there is the power button to switch on and off the
‘PAM V2’. Using the knob at the right of the front plate labeled ‘GAIN’
you select the gain to 38dB, 48dB, 58dB or 68dB (
d
ezi
B
el).
The selected gain is indicated by the LEDs in the middle of the front.
Most MM pick-ups (
m
oving
m
agnet) need a gain of 38dB, while MC
systems (
m
oving
c
oil) usually require gains of 58dB or 68dB. Also avail-
able ‘high output MC’ systems mostly will work properly with 48dB
gain. Please try out individual setting for your pick-up.
A knob labeled ‘input imp.’ is to be found at the back of the ‘PAM V2’
for selecting the terminating resistance to your pick-up. Please select
carefully. It will effect high frequency response. Using MM systems se-
lect imp.=47k
W
. MC systems may need resistance ranging from
imp.=100
W
to 1k
W
.
In case of any other resistance or capacitance needed by your pick-up
please refer to
page 8
for further instructions how to set up the appropri-
ate values using the sockets labeled
C/Rext
.
The active structure of your ‘PAM V2’ is equipped with two DC voltage
servos that build up an internal second order subsonic filter with a cut off
frequency of 10Hz. This will protect the woofer from unnecessary stress
or damage due to subsonic frequencies caused by wavy vinyls or outer
noise.
Nowadays interested listeners experienced tonal differences in using dif-
ferent power cords. In order to increase the value of your ‘ART’ you
have the opportunity to use high performance power cords.
It is advisable to protect and decouple your ‘PAM V2’ form outer noise
as the unit will amplify a frequency of 20 Hz by a factor of e.g. 20,000
with gain selected to 68dB!
