Reference - tone
The reference tone can be set for three different levels on the Dip-switches S3 and S4 on the
main board (see page 11). By changing a jumper on the board of the display, two different
reference-tone systems can be chosen:
•• Adjustable reference-tone. With this system, the level of the reference tone can be
adjusted by the master potentiometers. For this reason, two LEDs light up in the display. One
indicates the level for which the tone is set (three are possible) and one to control the fine
tuning when adjusting. When in reference mode, the step between two LEDs is 0,2 db, which
allows the adjustment with highest precision.
±
0 is when the LED on position 0 on the
display is lit up.
•• Calibrated refernce-tone. In that mode the reference tone is fix and can not be adjusted
by the master potentiometers. The left channel is identifiable by a short (2 milliseconds)
interruption of the signal in about two seconds interval.
The display
Two ballistics can be set over the DIP-switch S1. For applications in digital surrounding, we
recommend the use of the fast ballistic of 1ms attack time. This eliminates the need of having
to create an artificial headroom by low-level mixing. The factory setting is 1ms.
The switches are located close to the connector J4, which is photographically illustrated on
page 11.
The display is set to show always the outgoing signal also when monitoring the return signal
on the headphone.
To change this to have the display following the "PHONE"-switch an intervention of our
distributor or ourself is needed.
To access the dip switches on the board you proceed as described hereafter:
1. Switch off the unit.
2. Unscrew both screws, securing the cover (Attention, these screws could fall off and
get lost) and open it. The switches S1 and S4 are located below the connector J4
underneath the flat cable. Switch S3 is easily accessible below the DC-Converter
U46.
3. If needed disconnect the flat cable.
4. Switch to the desired setting.
5. Connect the cable again, close the cover and secure it with the two screws.
6. Switch on the unit.
