The sensor for the remote control is positioned beneath the glass plate in the front of the
amplifier; for an impeccable function of the sensor it is essential to keep the glass plate clear
of objects or immediately adjacent shelves etc. on top of the amplifier.
To change batteries, please unscrew the remote control at its back side, pull out the battery
compartment and replace the empty batteries by two new ones of the type AA according to
the illustration in the compartment. Please push the battery compartment completely back
into the remote control until the cover can be closed again easily.
>Used batteries are not to be thrown into household waste but be disposed at special waste
utilisation plants or collecting points according to the possibilities of the country in question.<
Adjustments :
The input selector switches the inputs. The selected input is indicated from top through the
glass plate at the rim of the selector switch.
By pushing the button "on-off" the preamplifier is connected to the power supply via relays,
the red LED turns off and the LED is on.
The button "mute" clears the inputs and outputs, the button is locked for the first two minutes
after switching the preamplifier on.
To protect the power amplifiers and loudspeakers, the DC-offset at the outputs is measured
andswitches off the outputs when a certain level is exceeded.
The level controls allow the separate gain-adjustment of the lineamplier for each channel in
0,5 dB-steps between 4...12 dB.
The optional phonoboard allows the adjustment of the input sensitivity in three stages:
1= 2mV / 47k Ohm, 2= 1mV / 600 Ohm, 3= 0,5mV / 600 Ohm
Different impedances and sensitivities are possible by resoldering the correlated resistors.
Setup :
First all needed inputs and outputs should be plugged in, and the preamp connected to the
power supply before this is connected to the mains. Be careful not to create a short circuit,
because a (lasting) short circuit can lead to damages in the preamplifier.
In order to connect the preamplifier to the mains, the power supply has to be plugged into a
mains-socket or a multiple plug with double poled power switch.
The mains-plug of the powercord has a red mark at one side, the pole of this side should be
connected to the phase of the mains to get the best sound quality.
The LED at the front panel of the power supply starts to glow when the power supply of the
preamplifier is connected to the mains. The power supply needs a minimum of current when
the preamplifier is switched off, only the micro-controller of the preamplifier is still under
current.
