Connections

Before connecting the MACHINE HEAD switch the power off at all connected units.

The rear panel provides AES/EBU- and S/P-DIF-inputs and outputs. Any additional channel, status and user-bits are passed through unaltered, and the outputs can be used at the same time if required.

The MACHINE HEAD operates with 24 bit word width. It accepts 16 to 24 bit inputs and will create output signals according to the input resolution.

For synchronisation purposes WORDCLOCK IN and WORDCLOCK THROUGH BNC connectors are fitted with a switchable 75 Ohm termination.

MIDI IN and MIDI THROUGH connectors allow presets to be selected via MIDI program change commands.

For easy upgrade of future software releases, the rear panel offers RS-232 interface for PC and RS-422 interface for MAC.

Installing Updates:

Note: All presets will be lost after installing a new software version!

1.Connect your computer with the MACHINE HEAD via a serial port with a standard Z-modem cable.

RS-232 for PC and RS-422 for MAC.

2.Open a terminal program like “Hyperterminal” on PC and make the following adjustments:

Baud rate: 9600; Stop bit: 1; Parity: none; Data bit: 8;

Handshake: no; Transfer mode: ZMODEM

3.Switch on the MACHINE HEAD and depress both

PRESET UP and PRESET DOWN until the LC-display says “wait for Zmodem download“.

4.Load the update file into your terminal

program and send it to the MACHINE HEAD. The LC- display shows the progress of the download in kB.

5.After successfully installing the new software version the LC-display says “download valid”.

6.Switch the MACHINE HEAD off and on after 4 sec. The new software version number is displayed in the first INFO page (simultaneously depress STORE and APPLY; also refer to CONTROL ELEMENTS No. 9, INFO).

7.If an error occurred during download the LC-display says

“download failed”. The MACHINE HEAD now waits for a new download. Please check all adjustments on your terminal program and try again. If you are still un- successful contact your local dealer.
