User manual MACKIE UP4161 DATASHEET

[. . . ] Activation of the balanced input priority turns on 18Vdc (300mA) power at a barrier connector on the rear panel, which may be used to drive LEDs or relays. The unbalanced input features a paralleled output and 0/­20dB sensitivity switch. 12dB/octave Bass and Treble shelving equalization with up to 12dB of boost or cut at 100Hz and 10kHz can be applied to the output signal.

It shall operate on 115VAC or 230VAC at either 50Hz or 60Hz and have its source power supplied by a detachable IEC power cord. In addition, the unit shall be capable of being directly powered by a 24Vdc source such as storage batteries. The unit shall have a constant-impedance output to drive a 4 load at its rated output. It shall also have 25V, 50V, 70V and 100V constant-voltage outputs with like performance. The unit shall be capable of being remotely turned on from a stand-by mode, with a contact closure. The amplifier shall have an active balanced input and an unbalanced input. The balanced input connection shall be made through barrier connectors. The unbalanced input shall have a sensitivity switch on the rear panel to select between a nominal input signal of 0dB or ­20dB. [. . . ] LED status indicators shall be provided on the front panel to indicate power, stand-by mode, signal present at the output terminals, peak signals near clipping and an overload condition. The amplifier shall be a model UP4161 manufactured by Mackie Industrial.
