Levels

Selecting "Levels" and pushing the encoder enters the submenu.

Turning the encoder one detent to the right and back toggles between

channel A and B.

Pushing the encoder exits the submenu.

In the "Levels screen" the following values are displayed as bar graphs

and/or as numeric values:

Input gain/Temperature of the device

In the first line:

- the input gain setting of the respective channel is displayed as the

numeric value in dB

- the temperature of either the amplifier or the power supply

(whichever value is higher).

Input

Input signal level as bar graph and the numeric value is displayed in

dBu. The small vertical mark [A] represents the threshold of input level

where an input overload occurs (red OVL LED). The colon [B] acts as a

peak hold for 1 s.

Headr. (Headroom)

The bar graph shows the relationship between modulation and gain

reduction (GR). The small vertical mark [A] indicates the gain reduction

threshold (0 dB headroom), the colon [B] acts as a peak hold for 1 s. The

gain reduction (GR) LED (yellow) indicates a gain reduction of more than

3 dB.

Impedance Z

The impedance of the loudspeaker(s) presented to the output of the D6,

displayed only as a numeric value in ohms. The value is measured with

the actual output signal and may therefore vary with its spectral

content. The measurement range reaches from 0 ohms (short circuit) to

255 ohms (open loop, I = 0, Z ⇒ ∞). When the signal is too low the

maximum of 255 ohms is displayed.

Power

The actual output power, displayed as bar graph and as a numeric

value in watts, the colon [B] acts as a peak hold for 1 s.
