Mackie AM4060 Brochure

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.
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.
