AMPLIFIER AM4060 Integrated Mixer/Amplifier AM4060 Architects' and Engineers' Specifications The integrated mixer/amplifier shall have a nominal output power of at least 60W RMS. 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. It shall have a power switch on the front panel. The unit shall have a constantimpedance output to drive a 4Ω load at its rated output. It shall also have 25V, 50V, 70V and 100V constant-voltage outputs with like performance. Inputs to the unit shall include: at least four actively balanced microphone; two unbalanced, stereo Aux; and an unbalanced signal processing return. Outputs shall include: at least two unbalanced Tape (auxiliary) jacks with a common, continuously variable level control; and one signal processing send. Balanced connections shall be made through XLR connectors and unbalanced connections through RCA connectors. Microphone Input 1 shall have adjustable sensitivity between mic and line, selected by a switch on the rear panel. This input shall also be programmable to completely exclude or attenuate all other inputs when its priority link is activated by either a contact closure or a VOX circuit, with a continuously adjustable threshold. The XLR connector for Input 1 shall be wired, in parallel, to a barrier strip on the rear panel. Microphone inputs 2-4 shall have a 24V phantom powering circuit that can be disabled with a switch on the rear panel. These inputs shall be equipped with a high-pass filter and a low-pass filter having a response of 12dB/octave and fixed -3db points at 300Hz and 7kHz, respectively. Each of these filters shall be enabled by a switch on the rear panel. Additionally, these inputs shall be programmable to completely exclude or attenuate all other inputs except for microphone input. Two auxiliary voltage outputs shall be provided on the rear panel to drive accessory relays and LEDs. The relay output shall deliver +18Vdc at 300mA. Voltage shall go high when any microphone priority function is active. The unit shall have, on its front panel, continuously variable controls for each microphone input, an auxiliary input selector switch, a master volume control, as well as bass and treble shelving filter controls. The shelving filters shall have a range of ±12dB, with the frequency for the bass fixed at 100Hz and the treble fixed at 10kHz. LED status indicators shall be provided on the front panel to indicate power, signal present at the output terminals, peak signals near clipping and an overload condition. The integrated mixer/amplifier shall be a model AM4060, manufactured by Mackie Industrial.

New material, produc- tion methods, and design refinements are introduced into existing products without notice as a routine expression of that philosophy. For this reason, any current Mackie Industrial product may differ in some respect from its published description, but will always equal or exceed the original design specifications unless otherwise stated. ©1999-2001 Mackie Designs Inc.
