User manual ELECTRO-VOICE DC40 DATASHEET

[. . . ] Input channels 1-4 are designed to either be used as lowZ balance microphone or line level inputs. The combination connector on inputs 1-4 permits use of either XLR or ¼" input connectors. A signal appearing at either input 1 will automatically mute the other channels unless the mute function is defeated via a switch on the rear panel. [. . . ] A signal appearing at either input 1 will automatically mute the other channels unless the mute function is defeated via a switch on the rear panel. Inputs 5 and 6 are for auxiliary line-level sources such as tape or CD players. Mono or stereo signals may be applied to inputs 5 or 6. The left and right components of a stereo signal can be applied to the dual RCA phono jacks of these inputs and mixed together to drive the built-in monaural power amplifier. A rear panel paging input with gain control is provided for the paging output of a telephone system. An audio signal appearing at this input automatically mutes all other inputs. A preamplifier output jack and power amplifier input jack permit the mixed output to be fed to an external signal processor (graphic EQ or compressor), and then returned to the built-in amplifier. Separate bass and treble equalization controls shall be provided. The mixer amplifier shall meet the following performance criteria: output power shall be 60 watts; total harmonic distortion shall be less than 1% at 1 kHz; frequency response shall be within ±3 dB from 50 Hz to 15 kHz; input impedance shall be 600-ohms (balanced inputs) or 47 kW (unbalanced inputs); nominal load impedance shall be 4-, 8- or 16-ohms for voice-coil-connected loudspeakers, 25, 70. 7 or 100-volt nominal transformer windings for the constantvoltage output. In addition to a preamplifier output/power amplifier input link, there shall also be a line-level balanced XLR output. The mixer amplifier shall operate from either a standard 120 V ac 50/60 Hz or a 24V dc power source , and measure 13. 3 cm (5. 2 in. ) high x 48. 0 cm (18. 9 in. ) wide x 32. 0 cm (12. 6 in. ) deep. The net weight shall be 8. 5 kg (19. 0 lb). The mixer amplifier shall be the ElectroVoice ® Model MA-606.
