6 – DX810 OUTPUTS A/B These 3-pin Phoenix-type connectors supply a balanced line-level signal from OUTPUTS A and B . LOGIC I/O This 25-pin D-Sub connector provides 10 logic control inputs and 10 logic control outputs (open-collector). These inputs can be used to control a wide variety of DX810 functions via external switching.
DX810 – 7 3. INST ALLA TION CONNECTIONS Connecting Balanced Sources Use high-quality three-conductor cable for balanced connections, such as Star Quad by Belden, Canare, or Mogami, etc. The better the shield, the better the audio signal is protected from induced EMI and RFI.
8 – DX810 Connecting the LOGIC I/O This is a 25-pin D-Sub connector . There are 10 programmable logic inputs and 10 programmable log ic outputs. In addition, there is an 11th fixed logic output to indicate "System OK." They are all active- low circuits.

10 – DX810 Bus A and B Input T rim There is no metering after the BUS A and B input TRIM controls. These controls must be adjusted by ear . Start the program source playback for all sources connected to the BUS A or BUS B input. Slowly increase the TRIM control to the center position (12 o ’ clock), which is unity gain.
DX810 – 11 USING THE DIRECT OUTPUTS The DIRECT OUTPUTS provide an unbalanced line- level signal from each of the 8 Input channels. This signal comes from the output of the preamplifier stage on each input channel, prior to the A/D converter and subsequent digital signal processing.
12 – DX810 The logic functions assigned to each individual logic input and output are configured using the DX- 810-PC application. In addition, each logic input and output can be assigned a descriptive name (up to 32 characters) for easier identification within the PC application.
DX810 – 13 Preset Active A logic output can indicate when a particular preset is active. Force On A logic output can indicate when a particular input or group is being forced on. Priority active A logic output can indicate when a particular input or group force-on priority is active.
14 – DX810 CONNECTING A PC Use a standard DB9 (male/female) computer cable to connect a PC to the DX810. The DX-810-PC application uses COM1 on the PC by default. Y ou can select a different COM port by clicking on Advanced in the top menu bar and selecting Configure COM Ports .
DX810 – 15 TOP SECTION The T op Section includes the Menu bar , the Active Logic Input and Output indicators, and Preset, On Line, and Panel Lock controls. Menu Bar The following menus are available in the Menu bar at the top of the screen: File Open (Ctrl+O) Opens a previously saved session.
16 – DX810 Firmware Upgrade This allows you to select an OS upgrade file to upload to the DX810 as they become available. Click Select File in the Firmware Upgrade window and the Select OS Upgrade File dialog box opens. Browse to the location of the OS upgrade file (with a .
DX810 – 17 Note: When changing presets, the faders change position quickly on-screen, but the audio actually ramps according to the Ramp T ime setting. Set Powerup Preset Select this to open the Powerup Preset Selection window . When None (last state) is selected, the DX810 returns to its state when it was last turned off.
18 – DX810 Output EQ This toggles the Output EQ window open and closed. It duplicates the function of the Output EQ button in the Button Section. Compressor This toggles the Compressor window open and closed. It duplicates the function of the Compress button in the Button Section.
DX810 – 19 Button Section The Button Section includes the assignment buttons (Force Ctrl, Logic In, Logic Out, Groups, Input Proc, Out Proc, Mute Ind) and the DSP buttons (Combine, Input EQ, Output EQ, Compress, Gate, Delay , X-Over). Assignments Force Ctrl Click this button to open the Force Control window .
20 – DX810 Logic Out Click this button to open the Logic Output window . Make the following settings and assignments in the Logic Output window: Name: Enter a name for each Logic Output, up to 32 characters. Function: Select one of 10 different functions in this drop-down box.
DX810 – 21 Mute Ind Click this button to view the Active Mute Groups indicator in the upper left corner of the screen. If a group mute button is active, the associated indicator lights up in the Active Mute Group indicator . Remotes Click this button to open the Remote Mapping window .
22 – DX810 3. Combining only affects crosspoints and outputs that are assigned to control groups (see rule 1). Any crosspoint or output that is part of a combination, but is not assigned to a control group, will be muted when the combination is inactive, and audible when the combination is active.
DX810 – 23 is created, activated, and then deactivated. That is when the combine rules take effect. Assign Combinations Now we ’ ll create the combination to allow the inputs for rooms A and B to be heard in both A and B outputs when C1 is active.
24 – DX810 Output EQ Click this button to view the Output EQ controls. Click the output letter buttons ( A-J ) to select an output after the Output EQ window is open.
DX810 – 25 • Ratio: This determines the c hang e in output level. It i s a function of the ch ange in input level (at full compre ssion), onc e the threshold ha s been fully exc eeded. It is calibrat ed in decibels, with a range fr om 1.0:1 (off) to 20:1.
26 – DX810 reflected in the Crosspoint Matrix Section by “ blanking out ” all but the top row of crosspoints for the linked crossover outputs. Note that only contiguous outputs may be linked to create a crossover . Linking outputs together for the crossover automatically links those outputs in Output EQ processors.
DX810 – 27 INPUT SECTION This section includes the eight input faders along with their associated bargraph input level meters, Select and Mute buttons, and name box. The fader adjusts the mix level from the input to the output selected in the Crosspoint Matrix Section (indicated by the highlighted row).
28 – DX810 Click the letter button when a processing window is showing (except Gate and Input EQ) to adjust the processing options for that output. Use the box to the right of the Output Section to enter a name for the output (e.g., Main Left, Control R), using up to 32 characters.
