Architects’ and Engineers’ Specifications
The power amplifier shall have a nominal output power of
160W 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 4
Ω
load at its rated output. It shall also have 25V,
50V, 70V and 100V constant-voltage outputs with like per-
formance. The unit shall be capable of being remotely turned
on from a stand-by mode, with a contact closure.
The amplifier shall have an active balanced input and an
unbalanced input. The balanced input connection shall be
made through barrier connectors. The unbalanced input shall
have a sensitivity switch on the rear panel to select between
a nominal input signal of 0dB or –20dB. This input shall be
wired, in parallel, to an unbalanced output connector.
Unbalanced connections shall be made through RCA connec-
tors. The unit shall be capable of being connected to two dif-
ferent input program sources. The balanced input shall be
programmable to completely exclude the unbalanced input
when its priority link is activated by a contact closure. The
inputs shall be equipped with a high-pass filter and a low-
pass filter having a response of 12dB/octave and fixed
300Hz and 7kHz, respectively. Each of these filters shall be
enabled by a switch on the rear panel. An overload condition
shall cause an auxiliary voltage of 18Vdc at 300mA to be
present at a pair of terminals on the rear panel.
The unit shall have on its front panel continuously variable
controls for the master volume as well as bass and treble
shelving filters. The shelving filters shall have a range of
±12dB with the frequency for the bass fixed at 100Hz and the
treble fixed at 10kHz. LED status indicators shall be provided
on the front panel to indicate power, stand-by mode, signal
present at the output terminals, peak signals near clipping
and an overload condition. The amplifier shall be a model
UP4161 manufactured by Mackie Industrial.
