Connector and Indicator Descriptions

CH 1 INPUT, CH 2 INPUT: balanced female XLR’s. If not using the DataPort for inputs, these are where you connect the line-level audio inputs to the DSP-4.

They are electronically balanced with an input impedance of 8.3k Ohms. If used in an unbalanced configuration, the input impedance is 3.7k Ohms. Input sensitivity is software

CH 1 OUTPUT, CH 2 OUTPUT: pseudo-balanced male XLR’s. These outputs provide post-DSP (processed) signal from the DSP-4 for downstream devices (amplifiers, mon- itoring busses, daisy-chaining the processed signal to a second amplifier). When using with non-DataPort amplifi- ers, these outputs should be connected to your amplifier’s input connectors.

selectable.

SIGNAL indicator: This green LED illuminates when the DSP-4 detects an input signal on either channel. Dual brightness levels indi- cate signal level. At -40dB fs, it will light dimly; at - 20dB fs it will light brightly.

RS-232: DB-9 female jack. Use for serial cable connec- tion between the DSP-4 and the computer. Connection is required only for setup and real-time control of the module. Connection need not be maintained for use.

POWER indicator: This blue LED illuminates when the module has power properly applied.

Chassis Lance: Use this lance to secure accessory power cord (if used) with a wire tie.

EXTERNAL POWER: 2.5mm barrel connector- Center (+), Outer(-), 15 VDC, 300 mA. Use if your amplifier does not supply the required operating volt- age from its DataPort.

DATAPORT: This is the “input” DataPort. If using with QSC DataPort prod- ucts that supply audio inputs or provide amplifier control & monitoring, this is where they are con- nected. If using this DataPort for audio inputs, do not apply input signal to the XLR inputs.

DATAPORT (unlabeled): This is the “output” DataPort. If the DSP-4 is directly mounted on a 2-RU, 2 channel QSC DataPort equipped ampli- fier, this connector plugs into the amplifier’s DataPort con- nector.

If used with 3-RU, 4-, or 8- channel QSC DataPort equipped amplifiers, the DSP- 4 module will need to be remotely mounted and a male-female DataPort cable used to interconnect the amp & module.

If used with a non-DataPort amp (QSC or other), this con- nector will not be used.
