DX810 – 15
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.
Using the Digital Signal Processors
The DX810 has five powerful floating-point 32-bit
digital signal processors (DSPs) to implement the
digital audio processing functions.
Input 3-Band Shelving EQ With Parametric
Mid-Range Control
Output 5-Band Parametric EQ
Output 31-Band 1/3 Octave Graphic EQ
Input/Output Compressor
Input Gate
Output Delay
Crossover
Plug-Ins
A number of software plug-ins will be available to
download to the DX810 via the COMM PORT
connection to a PC. Plug-ins can be used along
with the EQs and compressor described above.

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).
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.
Use the DIRECT OUTPUTS to connect a continuous
music source (e.g., satellite feed, prerecorded back-
ground music, or multi-disc CD player). This may connect
to a telephone system music-on-hold input. It may
provide a feed to a multi-track recorder (for recording), or
a mixing console (for additional zone coverage).
