BALANCED INPUT - UNBALANCED OUTPUT
THE INPUTS
The inputs feature gold plated XLR-type
connectors. They are situated on the rear of
the unit and marked numeric (1 ... 4) and
according to their channel (Left, Right).
The polarity of the inputs meets AES 14-1992:
1 = ground, 2 = (+) phase, 3 = (-) phase
The input impedance is 10 kohms.
To avoid hum loops, signal ground can be
removed from each input by pulling jumpers
inside the unit.
Refer to: The Earth / Grounding Concept !
HINT
When feeding unbalanced signals to the
balanced inputs, pin 3 of the corresponing XLR
input must be tied to ground (pin 1).
THE DIFFERENTIAL AMPLIFIERS
The differentiation of the input signal is made
with a special electronic
integrated narrow-tolerance components for
highest available common mode rejection.
OPTION
As an option the unit may be equipped with
high quality ZFT = Zero-Field-Transformers in
its inputs. The technical data of these
transformers exceed IRT recommendations.
THE AMPLIFIERS
The input signals are fed to separate amplifier
branches. To match all possible operational
conditions, gain can be adjusted separately for
each output on the front panel.
Gain adjustment in the range from -24 ... +3 dB
is provided by a multiturn trimpot.
THE OUTPUTS
The outputs are equipped with gold plated
cinch connectors and situated on the rear
panel. They are marked numeric (1 ... 4),
colored and according to their channel (Left -
white, Right - red).
circuitry with
Additionally the unit disposes gold plated
output connectors on the front panel which are
connected in parallel to the rear connectors.
They are marked numeric and according to
their channel.
Output impedance is approx. 30 ohms.
