Transducer
All three Transducer level controls infl uence output levels. Therefore it is important to under-
stand their existing mutual effects and the overall results. These controls have been designed
purposefully with a percentage scaling, as one structured in dB is in fact not possible. The
input signal itself – coming from the guitar amp – is a power signal that is no longer measur-
able or depictable in dB. Thus a “0dB” input level is not defi nable, and thus other levels
may not be derived from it. Because this reference point is lacking, it is also impossible to
construct subsequent controls in dB scaling.
1. As an initial setting, move the Speaker Action, Miking Level and Output Gain controls to
50%.
2. In order to provide the following peripherals with proper levels, adjust the Outupt Gain*
control appropriately.
3. For desired adjustments to the Transducer sound you have available the four toggle switch
options provided by Speaker Action and Miking Level controls.
With a more limited Speaker Action a signal will sound cleaner and have more defi nition.
A higher Speaker Action offers stronger compression and more overtones which begin to
introduce light speaker cone distortion.
A limited Miking Level provides both more highs and refi nement in overtones with some-
what reduced mids. As Miking Level is increased, the signal thickens. Mids and bass are
compressed and moved to the foreground.
4. You can adjust overall level controls that are effected by Speaker Action and Miking Level
with the Output Gain* control.
*: The Output Gain control functions only with the Line Outputs. If you are routing from the
Mic Level Output, use the control in your following mic preamp to adjust the overall level.
It is important to consider added power amp distortion, as it is the basis for the Transducer‘s
concept with its ability to process up to a 200 Watt, 8 ohm cabinet-amplifi ed signal. Avoid too
much mental separation in what should be your integrated Transducer level control thinking,
as just with past situations that employed traditional guitar amp and cabinets, you must
consider the interaction with a guitar amp – and here especially in relation to the preamp
and master gain. This is really the only way you can achieve the effects you‘re looking for (in
particular, the distortion from pre and power amps).
Please pay attention to the instructions for connecting guitar amps to the Transducer on
page 11!
Setting Examples for Clean, Crunch and Lead Sounds
Just as you would choose a cabinet matching your amp you can use the settings of the
following presets. Our presets correspond to the respective amps and provide a fi rst orienta-
tion for your individual settings.
Speaker Action and Miking Level controls determine both the basic sound and leveling; indi-
vidual experimentation is always required here. The Transducer delivers a full bandwidth
signal from 20 Hz to 20 kHz, so we recommend to create the basic sound without further EQ
processing fi rst. Once you have found your sound you can go ahead with any desired effects.
WARNING
If an amplifi er is connected and the Signal LED illuminates though a signal is not present or
too much noise from the amp is not the reason, the lighted LED can indicate a high frequency
resonance of the amp.
In this case turn down the master volume of the amp until the LED goes out. High frequency
resonances can overload and damage the guitar amp!
Such problems are not a result of Transducer use, but reside within the guitar amp.
