Calibrate

NOTICE:

Ensure that all components of the system are wired and working
correctly before executing the calibration!

Selecting "Calibrate Now" enters the submenu "Calib. Load
Monitoring" and the following message will be given as a precautionary
measure:

Selecting "Calibrate" starts the calibration procedure while the progress
of the procedure is displayed. It can be canceled/interrupted and
restarted at any time by pushing the encoder during the procedure.

After a successful calibration the reference values are displayed and
"Ok" appears in the bottom line of the calibration screen.

Confirm to get back to the Load Monitoring menu.

If the calibration was not successful a respective error message will be
displayed. Also refer to section 2.6.2 System Check, Load and Input
Monitoring on page 28.

Reset of Load Monitoring errors

To reset error indications either:
- Power Off/On on the device or remotely.
- Switch Load Monitoring Off/On on the device or remotely.

Freq. Generator               off

Frequency Generator

Each amplifier channel is equipped with an independent signal
generator offering pink noise or a sine wave signal.

Frequency Generator 

A

Back 

 Mode   off

Level 

 -42.0dBu

Frequency                1000Hz

The generator can be used to check the connected loudspeakers or to
identify room resonances, for example. The generator is inserted in the
signal path after the delay and before the loudspeaker equalization.
The test tone will sum with any input signal present.

Frequency Generators

are used by

Load Monitoring

Ok

As a precautionary measure the frequency generator will always be off
(Mode = off) after the D6 is powered on. The frequency generator
provides the Pilot Signals for the "Load Monitoring" function. When
using "Load Monitoring" the frequency generator function is not
available and a message is given as shown in the graphic opposite.

Mode

Selecting "Mode" and pushing the encoder allows the following settings:

off:

generator off.

Sine:

sine wave generator (indicated as " " on the main screen).

Pink:

pink noise generator (indicated as " " on the main screen).

Level

Level of the frequency generator in dBu covering a 63.5 dB range from
–57.5 dB to +6 dB in 0.5 dB steps. The level value corresponds to the
level at the controller signal input. The actual output voltage depends on
the channel input gain, the frequency dependent gain of the selected
loudspeaker configuration and EQ settings if used.

Frequency

Frequency adjustable in the range of 10 Hz to 20 kHz in 1 Hz steps.
