EAW DX810 Using Inputs, Using the BUS a and B Inputs, Software Updates, Bus a and B Input Trim

Bus A and B Input Trim

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. Then adjust the TRIM control up or down to attain a balance within the total mix at the A and B outputs.

Accessing the Digital Signal Processors

The DX810 has five powerful floating-point 32-bit digital signal processors (DSPs) to implement the digital audio processing functions. Access the processing windows by clicking on their buttons in the Button Section, or double-clicking on the DSP name in the Input Proc or Output Proc windows.

USING INPUTS 1-8

Connect the microphones or program sources to Inputs 1-8. Examples of program sources include a CD player, tape deck, tuner, satellite feed, TV audio, jukebox, or other audio source. Each input has a separate Phoenix-type connector for a mic or line- level input.

TRIM

Use the TRIM control to adjust the gain of the input preamp stage according to the level of the input signal. Refer to the “Quick-Start” section (Set the Levels) for instructions on how to set the TRIM controls.

LEVEL

The up/down arrow buttons on each channel are used to adjust the mix level for each channel going to the A and B outputs (use the on-screen faders for outputs C-J). Use these to fine tune the mix or relative loudness of each input signal that is connected to the DX810.

When adjusting these buttons, the channel meter indicates the gain of the channel relative to the maximum gain of +10 dB. After 5 seconds, the meter reverts back to indicating the actual input signal level of the channel. This metering is pre-EQ and pre-LEVEL control.

Unity gain is indicated when the –10 and –7 dB LEDs are both lit on the meter (or “U” on-screen).

EQ

Each Input 1-8 has a 3-band shelving EQ with a parametric mid. This is adjustable from the PC only. It provides 15 dB of boost or cut with user selectable corner and center frequencies (LO: 20 Hz-500 Hz; MID: 20 Hz-20 kHz HI: 500 Hz-20 kHz).

USING THE BUS A AND B INPUTS

These inputs provide a direct analog connection to the BUS A and B buses. These input points are post- DSP and post-D/A converter, and accept a balanced analog line-level signal. Use these to connect an additional program source to a zone, or to connect the Zone A and B outputs from another DX810.

TRIM

Use the TRIM control to adjust the signal level at the BUS A and B inputs. Typically, this control would be set to the center detent position (unity gain). However, it can be adjusted up or down by 20 dB to achieve a balance between the signal at the BUS A and B inputs, and the signal on the internal A and B buses.
