Crescendo duo
Two-Channel Microphone Preamplier with
V Technology
The Crescendo features a fully balanced signal flow. The input stage uses duo
pairs of matched PNP Transistors (Dierential Input Transistors) for extremely
low noise and a very high common mode rejection.
Both input stages have six th generation V SPL SUPRA Operation Ampliers
each.
The transformerless design of the input/output stages guarantees highly linear
amplifying.
The output stages operate as current ampliers and therefore provide Class-A
operation with more than 6mA quiescent current.
Start up
Read the security advices on page .
Make sure that the selected mains voltage of the Crescendo is according to duo
the mains voltage of your region.
Make sure that the mains switch on the rear of the Crescendo duo is set to O
(O = O / ON = I).
Connect the supplied power cord to the Crescendo and an appropriate duo
mains socket outlet.
If the supplied power cord does not match your mains socket outlet, please contact your dealer.
Please connect the outputs of the Crescendo to the inputs of your audio duo
interface or mixing console.
Connect your microphones to the inputs and of the Crescendo with duo
high-quality microphone cables.
Microphone cables not included in the scope of delivery.
Switch on mains on the rear of the Crescendo (On = I).duo

The phantom power required for condenser microphones can be activated with
the V switch.
If phantom power is on, the V LED lights up blue.
IMPORTANT:
Use phantom power only for condenser microphones. For all other microphone types – especially
ribbon micorphones – switch o the phantom power!
Use the Mic Gain switch to adjust the preamplication gain in dB steps.to
The Output Gain controls the output level from - to + dB.
With the OUTPUT switch the signal can be completely switched o.
The polarity of a microphone signal can be inversed (°) with the Polarity
Inversal switch.
The High Pass switch activates a high pass lter with dB per ocatve at Hz.
If the input signal is too hot, switch on PAD. This reduces the level by dB.
You can make the VU Meters less sensitive by activating the VU-dB switch.
