the desired chase speed. The SPEED FADER will over ride a Tap Sync setting as soon as it is moved. The case speed is off when the Speed fader in the minimum position called Show Mode this can be over written with the Tap Sync button, simply move the speed fader up and back down to stop again. In this position the Step button can be used to go trough the programs steps one step at a time.
• The program should now be chasing to the desired speed set in 5.).
D. PLAYING A SCENE PROGRAM WITH AN AUDIO CHASE:
(Running the new recorded program above with an audio input chase or by simple tap­ping the top panel for the internal microphone.)
• Set the mode to Scenes by pushing the MODE SET button until the LED for the Scenes mode is lit.
• Turn ONthe Audio chase (if it is off) by pressing the AUDIObutton. The audio LED should be lit.
• Press the PAGE button until the page LED over the "3" is lit. This means we are select­ing scene programs between 25-36.
• Raise the SCENES CHANNEL 28 FADERto max. This selects the scene program to run. The light intensity of the program is controlled by this fader.
Starting the audio chase with the internal Microphone
The chase can be started by raising the AUDIO FADER to full and tapping the front panel each time it is tapped the program should move one step. If music is playing loud enough or other sounds are loud enough they will trigger the program to chase. By lowering the
AUDIO F
ADER the internal microphone will become less sensitive.
Starting the audio chase using the Audio input jack
First, turn down the AUDIO F
ADER. Then plug into the Audio INPUT JACK
a music source
like a tape deck or CD player. With the music playing, bring up the AUDIO F
ADER
. The audio input can be over driven and not chasing properly. So move the Audio fader up slowly to find the point where the scene program is chasing the audio evenly. The first setting should be good for changes of music on the same source, but an adjustment maybe needed for bigger changes in the music source.
