Fig. 1: Amplifier Control Panel (ACP)
General functionality:
Pressing the "Menu" button activates the Amplifier Control Panel; additional presses cycle through the
available functions. If no input is made for 30 seconds, the current setting is saved and the menu is
exited. The control panel then switches to standby mode (status LED remains active, gain display is
dimmed).
Gain & Clipping indicator
a
The LED display shows the current gain
value (in the image below: 3 Volts) and
serves as a visual reference during
adjustment.
Two lit LEDs indicate an intermediate
value (e.g. 3 V and 4 V = 3.5 V).
If one or two LEDs light up red, the input
signal is overdriven and the gain should be
reduced.
For more information, see page 19, point 7.
