Auto Adjust
Some pickups show a pretty high level tolerance between the left and right channel. In this
case the 100 is equipped with an automatic level adjust function. This function measures
the channel difference and automatically adjusts it. This requires that your record player is
configured correctly.
PLEASE NOTICE:
During the Auto Adjust measurement the unit will set up the technically
optimal input amplification. You can change this setting, if another input amplification
sounds better to you.
How to approach:
Select a moderate volume, household noise level at maximum.
Put the test record on your record player. Now lower the pickup on the record. The preamp
requires a 1kHz sine wave stereo signal. As soon as you hear the measurement signal,
activate the measurement by pushing the
AUTO ADJUST switch key
(22)
up for
approximately 2 seconds.
During the measurement process the
AUTO ADJ ON LED (12)
will flash.
After incorrectly finishing the adjust process the
AUTO ADJ ON LED (12)
will stop flashing
and the
AUTO ADJ OFF LED (12)
will illuminate.
After correctly finishing the adjust process the
AUTO ADJ ON LED (12)
will stop flashing
and will illuminate constantly.
In case of incorrectly finishing you should check your record player if the right track was
selected, the connectors for any errors and the properties of the 100 preamp.
After correctly finishing the adjust process you will be able to deactivate it by pushing the
AUTO ADJUST switch key (22)
down. Pushing up the
AUTO ADJUST switch key (22)
will
activate the function any time.
Defaults
To recover factory settings the 100 preamp offers the option to load the default parameters.
All adjustments will be deleted, including the Auto Adjust.
With a combination of keys on the front panel similar to the activation of the volume control
the default parameters can be loaded:
1.
Use the
POWER switch (23)
to switch the 100 into standby mode.
2.
Now, simultaneously, you have to pull down the
DIM / VU-Meter switch key (19),
AUTO
ADJUST switch key (22)
and the
ADC switch key (21).
Hold these three keys
simultaneously while you now switch on the 100 preamp with the
POWER switch (23)
.
After correctly loaded default parameters, the settings are as followed:
•
Load:
75
Ω
/ 120pF
•
Gain:
66dB / 46dB
•
Output:
0dB
•
Subsonic:
ON
•
Variable:
OFF
•
VU-Meter:
Mono
•
DIM:
maximum brightness
•
ADC:
OFF
•
Auto Adjust:
OFF
Previous Auto Adjust parameters will be deleted by loading the default parameters and
need to be calibrated again.
ERRORDISPLAY
Since the 100 Phono preamp is not equipped with a classic display, the
POWER LED (24)
will indicate any errors by
flashing. Should an error occur, the 100 preamp will switch itself into standby mode.
In case of a flashing
POWER LED (24)
in any color we ask you to switch of the unit and disconnect it from the power
grid. After approximately 10 seconds try again to switch on the 100 preamp. If there is still any error, please contact
your authorized dealer.
