Transducer
Power Input
Here you connect the guitar amp‘s loudspeaker output. Connector variant and pin confi gura-
tions follow industry standards: Unbalanced 1/4” Jack connector with the signal at the tip and
ground at the sleeve.
IMPORTANT INFORMATION:
As with any typical amp and cabinet cabling, it is critical to observe loudspeaker cable of
a minimum 1.5 mm
2
cross section. Guitar or line cables can lead to amplifi er damage! We
recommend to use cables with a maximum length of 3 meters/10 feet for lossless signal
transmission.
WARNING: Connecting Guitar Amps and the Transducer
Many guitar amps are not designed for sustained maximum level operation, and if run this
way, it can lead to overloads and power amp damage. At high levels, amps can produce high
frequency oscillations which can destroy output transformers. Moreover, this can cause
audible unwanted output transformer distortion. Such problems are not a result of Transducer
use, but reside within the guitar amp.
Even in situations where you might wish to push the guitar amp to its limit in conjunction
with the Transducer, you should always be sure to allow for ample power reserves to avoid
endangering the amp itself!
In the same way a guitar amp and box should never be run knobs full to the right, so should
you avoid running the Transducer this way. Therefore we strongly recommend that the guitar
amp should never be run at over 70% of its maximal signal level!
Look for the amp‘s “Sweet Spot” as you make adjustments to it. This is almost never in the
upper level output range. Where the amp‘s bass starts to sound “spongy” and somewhat
undifferentiated is the place where your master level control should be turned back.
The guitar amp output must be rated at 8 ohms! Only connect amplifi ers rated at a 100 W
maximum to maintain a further 100 W reserve for signal peaks. A guitar amp may be used
ONLY within its normal operating parameters. The Transducer may be loaded up to 200 W.
But please note that a 100 W amp at higher volumes, eventually combined with further effects,
produces peaks far above 100 W. Therefore we strongly recommend connecting amps rated at
a maximum of 100 W.
Speaker Thru
This output provides for a passthrough from guitar amp to speaker in order to allow for the
connection of an additional 4, 8 or 16-ohm cabinet. This setup makes it possible to have a
traditional amp and cabinet combination sound sent to the stage and at the same time, route
the Mic Level or Line Output for PA or recording.
At Speaker Thru the amp signal appears with a -8dB lowering of the original signal level. The
guitar amp therefore can be driven into saturation also at moderate levels.
Connector variant and connections follow industry standards: Unbalanced 1/4" Jack connector
with the signal at the tip and ground at the sleeve.
