UP 4000 Series
Power Amplifier
UP4161
AMPLIFIER
■
The UP4161 is designed for continuous duty in
speech, music, paging and sound reinforcement appli-
cations in churches, schools, offices, arenas, hotel
meeting rooms, convention centers, recreation facili-
ties and other venues demanding high performance,
flexible features and rugged dependability.
■
The UP4161 offers two discrete inputs with priority.
The main program input is actively balanced and termi-
nated 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 priori-
ty to the balanced input. Activation of the balanced
input priority turns on 18Vdc (300mA) power at a barri-
er connector on the rear panel, which may be used to
drive LEDs or relays. The unbalanced input features a
paralleled 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 4
Ω
and 25V, 50V, 70V and
100V constant voltage. The output stage is fully pro-
tected against permanent damage caused by overload-
ing, shorts and extreme temperatures.
■
The UP4161 will operate on either 115 or 230VAC,
50/60Hz, supplied by a detachable IEC power cord.
Insulated terminals to connect a backup 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, sig-
nal present at the output, peak and output overload.
■
Accessories include rack mounting ears.
