EAW DX810 instruction manual BUS a and B Trim, Record Out, DX10e Expansion Panel, IEC AC Socket

TRIM

This rotary analog control is used to trim the gain of the input signal for optimum signal-to-noise ratio in the preamp stage. For mic-level signals, it provides from 0 to +60 dB of gain. For line-level signals, it provides from –30 dB to +30 dB of gain. Unity (0 dB) is at the center position. This control accepts a maximum input signal of +18 dBu before clipping (at unity gain).

PHANTOM POWER

These switches apply phantom power (+48 VDC) to pins 2 and 3 of the selected mic input connectors. Put the PHANTOM POWER switch in the UP position for an individual channel when using a condenser microphone.

BUS A/B INPUTS

These analog inputs accept balanced line-level signals and route the signal to the internal A and B buses. These inputs may serve as additional zone inputs for program devices. There is no DSP processing on these inputs.

BUS A and B TRIM

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. The outputs can be used to provide logic for external indicators for a number of internal settings and conditions. They can also control switching to external devices. The function of each logic input and output can be programmed via software to suit individual applications. In addition, logic output 11 is dedicated to the "System OK" function. See page 8 for the Logic I/O pinouts.

REMOTE BUS

This 3-pin Phoenix-type connector can be used to attach optional remote controls to the DX810. Several remote controls can be connected to each other in a daisy-chain fashion to extend the remote control functionality of the DX810.

COMM PORT

These rotary analog controls are used to trim the gain of the inputs to the A and B buses. This trim control provides from –20 dB to +20 dB of gain, with unity (0 dB) at the center-detent position.

DIRECT OUTPUTS

This 15-pin D-Sub connector supplies an analog, unbalanced line-level signal from each of the eight program inputs, post-preamp and pre-processing. Use these outputs to connect to another mixing console for additional zone coverage, a telephone system for music-on-hold, or a multi-track recorder. See page 7 for the Direct Output pinouts.

RECORD Out

These RCA connectors supply unbalanced line-level signals from the A and B outputs. Use these outputs to connect to the inputs of a recorder. They can also act as additional line-level outputs to connect to an external power amplifier. The signals are the same as the main outputs.

This is identical to the COMM PORT on the front panel. Use this to connect to an RS-232 serial port on a personal computer or third-party controller (i.e., show controller) for external control of the DX810.

DX10e Expansion Panel

The DX10e provides eight additional independent balanced output mixes, (C-J).

24 VDC POWER

The DX810 can be powered using a 24 VDC power supply. This can serve as the primary power supply for the DX810, or as a backup supply in case of an AC power failure. The DX810 seamlessly switches to the backup supply if there’s a power loss. When both AC power and 24 VDC power are connected, the AC power is used and no current is drawn from the DC supply.

IEC AC Socket

Connect the supplied AC linecord to the IEC AC socket.
