Power Amplifier
UP4121
AMPLIFIER
■ The UP4121 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.
■ The UP4121 offers two discrete inputs with priority.
The main program input is actively balanced and terminated to a barrier strip connection on the rear panel.
The second input is unbalanced, and terminated to a
single RCA connector. A contact closure will give priority to the balanced input. 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
parallel 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.
■ Output modes include 4Ω and 25V, 50V, 70V and
100V constant voltage. The output stage is fully protected against permanent damage caused by overloading, shorts and extreme temperatures.
■ The UP4121 will operate on either 115 or 230VAC,
50/60Hz, supplied by a detachable IEC power cord.
Insulated terminals to connect a back up 24Vdc battery
are provided on the rear panel. Switchover to DC is
automatic. A programmable stand-by mode allows the
amplifier to be turned on remotely with a contact closure.
■ The front panel provides a master volume control
and controls for the bass and treble shelving filters.
The control knobs can be easily removed for security
and the recessed shafts covered with inserts supplied
with the unit. LEDs indicate power, stand-by mode, signal present at the output, peak and output overload.
■ Accessories include rack mounting ears.
■ All products from Mackie Industrial are covered by
our exclusive, one-time, NO FAULT repair policy in
addition to a five year limited warranty.
