10.14 Special (SPECIAL)

Gives access to 5 special functions which are steered by the SELECT keys 1 to 5. The current

state is signaled by the PAR LED. Here the function is directly switched off/on by the according

SELECT key, not via key 8.

SELECT 1: AES Sync for AES input 1 as sync source instead of the AES sync input at the D-

sub connector. Default: Off.

SELECT 2: Force sample rate for Mode2 microphones. This function can be switched off for

microphones that work according to an old AES42 standard. Default: On.

SELECT 3: Auto SRC. When this function is active, the SRC in an AES42 input is activated as

soon as a signal is applied, which is not sent by a Mode2 microphone. With auto SRC active,

the SRC cannot be switched manually. Default: On.

SELECT 4: Auto CP/SP. When this function is active, the transmission of control and sync

pulses depends on the microphone's properties. In this case, CP and SP cannot be switched

manually. Default: On.

SELECT 5: Display auto dark. When display auto dark is active, the display goes dark after a

couple of seconds without an entry on the front panel. Only the decimal points are still lit. In this

state, all buttons are locked and will only be unlocked by keeping a button pressed for a few

seconds. Default: Off

11. The Parameter Menu

11.1 General

After pressing the PAR button below the rotary encoder the DMC-842 enters the Parameter

menu. All eight PAR LEDs light up. Turning the encoder knob scrolls through the available op-

tions. After selecting the desired option press and hold the Select key of the channel where the

parameters shall be changed. Turning the encoder knob increases and decreases the current

parameter value.

All changes are stored automatically. With a second push on the PAR button the Parameter

menu is exit.

The Parameter menu grants direct access to settings which are usually handled comfortably by

the use of the included Windows software. Additionally it allows to change settings which might

become of importance in future revisions of the AES42 standard (including upcoming micro-

phones supporting these settings). But such changes would also be part of an update to the

Windows software. In short, the Parameter menu is not intended to be used daily, but as an

emergency function, giving access to all settings even without the use of a computer.

The Parameter menu includes a direct display only for the most important functions. The others

are configured by a combination of command byte and parameter byte, based on the table

found in the latest revision of the AES42 standard, and further information from the correspond-

ing microphone manufacturer. The DMC-842 and the Windows software provide functionality

based on the AES42 standard revision of 2006.

Note

: Microphones often do not support all the features defined in the standard. Settings per-

formed in the Parameter menu may not be carried out by the microphone, if the specific feature

is not supported. The supported features are shown in the Windows software.
