AM4060
Integrated Mixer/Amplifier
AM 4000 Series
I The AM4060 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.
I 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.
Features
I 4 Lo-Z, XLR Microphone Inputs
I 2 Stereo Auxiliary Inputs
I 60 Watt RMS, Convection Cooled
I 4Ω - 25V - 50V - 70V - 100V Outputs
I Switched 24V Phantom and H-P/L-P Filters
I 2 Tape/Aux Outputs with Level Trim
I Signal Processing Loop
I Output modes include 4Ω 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 temperatures. The AM4060
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.
I 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.
I Accessories include an easily installed chime.
I This Mackie Industrial product is covered by an
exclusive, one-time, NO FAULT repair policy in addition
to a five year limited warranty.

Architects’ and Engineers’ Specifications
100Hz and the treble fixed at 10kHz. LED status indicators
The integrated mixer/amplifier shall have a nominal out-
put 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 constant-
impedance output to drive a 4Ω load at its rated output. It
shall also have 25V, 50V, 70V and 100V constant-voltage out-
puts with like performance.
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.
Inputs to the unit shall include: at least four actively bal-
anced microphone; two unbalanced, stereo Aux; and an
unbalanced signal processing return. Outputs shall include:
at least two unbalanced Tape (auxiliary) jacks with a com-
mon, continuously variable level control; and one signal pro-
cessing 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 continu-
ously 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 com-
pletely exclude or attenuate all other inputs except for micro-
phone input.
Two auxiliary voltage outputs shall be provided on the
rear panel to drive accessory relays and LEDs. The relay out-
put 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 vari-
able 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

Mackie Designs continually engages in research related to product improvement. 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
