Product Description:
Guitar amplifiers with a tube power amp are very popular but have the problem of having to be turned up to very
loud volumes in order to achieve that sound of power stage distortion we all love. The Guitar Genius allows to
drive the power stage of a tube amp to the maximum whilst still playing at suitable volume levels for at home, or
even silently using headphones or in-ear monitoring. The integrated Loadbox in the Genius Box exactly
reproduces the impedance of a 4x12 speaker cabinet and is more than just a simple load resistance. This is
crucial for the sound of the driven tube power stage. Optionally, the speaker cabinet can also be connected to
the Loadbox. It is then supplied with approximately 40% of the emitted tube amplifier signal with 12 different
switchable volume levels. The amplifier signal can be picked up from two transformer-balanced outputs on the
Guitar Genius via a speaker simulation of a 4x12 speaker cabinet with four switchable characteristics. The
"Line-Out" on the front panel is for direct connection to the "Aux-In" on the Fischer Amps In Ear Amp.
This way the guitar amplifier can be recorded or used for practice silently or at reduced volume. The guitar
setup on stage can also be operated at reduced volume or silently using the in-ear monitoring.
The combination of Fischer Amps In Ear Amp and the Guitar Genius allows to mix the guitar signal from the
amplifier with the "Stereo/Mono-In Ear Mix" or with a backing track for practice purposes. The Guitar Genius
has an additional XLR headphones out so that the Fischer Amps Guitar In Ear Cable can be used for the guitar
signal and the Stereo In Ear Mix.

- Page 3 Transformer-separated line-out for speaker simulator signal, for instance, for connection to an optional Fischer Amps In Ear Amp. This gives you the option of mixing the speaker-simulated guitar signal from the amp with the In Ear mix or a backing track on the "In Ear Amp". The output level depends on the output of the connected amplifier and stands at –16dB.
- Page 4 Operating Controls and Connections on the Back Panel (1 ) Input for the Amp Signal Connect this Guitar Genius input to the speaker output on your guitar amp. The Guitar Genius is equivalent to an impedance of 8 ohms, therefore you should ideally use the 8 ohm output on your amp or set the impedance switch on the amp to 8 ohms.
- Page 5 XLR Line-Out Transformer-balanced XLR line-out for the speaker simulation amp signal for connecting to professional audio equipment. The output impedance is 600 ohms, the output level depends on the output of the connected amplifier and stands at –10dBV. The output levels can be taken from the table in the technical data for the Guitar Genius (see page 6).
