If the SAC-2K does cause interference to radio or television reception, you can try to
correct the interference by using one or more of the following measures:
- Turn the television or radio antenna until the interference stops.
- Move the SAC-2K to one side or the other of the television or radio.
- Move the SAC-2K farther away from the television or radio
- Plugthe SAC-2K ACAdaptor into anoutlet on adifferentcircuit thanthetelevision
or radio.
- Consider installing a rooftop antenna with a coaxial lead-in between the antenna
and television set.

The Motorfaders
The Motor Faders of the SAC-2K are touch sensitive. The host software receives a signal
when a fader is touched. This way the controlled program can differentiate between an
automatedfadermovementanduserinteraction.Thevaluescalerangesfrom0-255,whichis
themaximumvalue.
The Rotary-Encoder
The Rotary Encoders have display rings with 31 red LED segments. These LEDs can be
addressed directly by the Host software. Using slow movements allows the values to be
changedinincrementsof1stepupanddown. Fast turns allowsmooth increases ordecreases
acrossthewholevaluespectrumwithonlyonecompleterotationoftheEncoder.Thisallows
useoftheEncoderin a potentiometerlikefashion.
Additionally, theEncoders have a Push-button function.This functionis usedby different
programsindifferentways.Thefollowingaresomeexamples:
1.)The resetting ofa parameter toits‘ default value(i.e. Pan =Center).
2.)Turningon/offofafunction(i.e.turningon/offE.Q.).
