Mackie AM 4000 Series AM4160 Specifications

AM 4000 Series

Integrated Mixer/Amplifier

AM4160

AMPLIFIER

■

The AM4160 is designed for continuous duty

in speech, music, paging and sound reinforcement

applications in churches, schools, offices, arenas, hotel

meeting rooms, convention centers, recreation facilities

and other venues demanding high performance, flexible

features and rugged dependability.

■

Four microphone inputs are actively balanced, have

XLR connectors, and can be programmed to interrupt or

attenuate the line level inputs. Microphone inputs 2-4

feature switched 24V phantom power and switched

high-pass and low-pass filters. Microphone Input 1 can

be switched to line level, set to have priority over all

inputs, and can be activated by either VOX with an

adjustable threshold or a contact closure. Activation of

any microphone override provides 18Vdc (300mA) at a

barrier connector on the rear panel, which may be used

to drive LEDs or relays. Two unbalanced, stereo Aux

inputs are internally summed to mono and selected by

a switch on the front panel. Two unbalanced Tape (auxil-

iary) line level outputs with a level control and an 

unbalanced signal processing loop are also provided.

All are terminated to RCA connectors. 

■

Output modes include 4

Ω and 25V, 50V, 70V and

100V constant voltage. The smart output stage is fully

protected against permanent damage caused by over-

loading, shorts and extreme temperature. The AM4160

will operate on either 115 or 230VAC, 50/60Hz sup-

plied by a detachable IEC power cord. Insulated termi-

nals to connect a backup 24Vdc battery are provided 

on the rear panel. Switchover to DC is automatic.

■

The front panel provides level controls for each 

Mic, selected Aux and Master volume, as well as the

Bass and Treble shelving filters. The control knobs can

be easily removed for security, and their recessed

shafts covered with inserts supplied with the unit. LEDs

indicate power, signal present at the output, peak and

output overload. 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.

■

Accessories include an easily installed chime card.

■

This Mackie Industrial product is covered by an

exclusive, one-time, NO FAULT repair policy in addition

to a five year limited warranty.
