TOA IP-450D Amplifier
TOA's versatile IP Series Dual Channel Power Amplifiers offer high quality
sound output that is ideally suited for such professional audio system applications
as halls, hotel ballrooms and sports stadiums. Specially designed for compact
proportions and lighter weight, these pro-use amplifiers feature proven power
amplification circuitry that ensures outstanding reliability.When connected
to a 4 ohm load, the ruggedly constructed IP-600D
delivers 600W of sound output per channel (IP-450D: 450W, IP-300D:
300W). Stereo, Parallel or Bridged operation can be selected by way of a rear
panel-mounted mode selection switch.
Slimly designed for easy installation in standard 19” equipment racks,
these 2-unit-high amplifiers feature rugged steel chassis construction and a
solid black finish. Their attractive black zinc diecast front panels feature
a large, centrally positioned power switch surrounded by recessable input level
control knobs. Designed to prevent accidental setting changes, these knobs must
first be pressed to raise them above the front panel surface for input level
adjustment. LED indicators provide instantly recognizable readout of operating
conditions such as signal presence, clipping, protection circuit activation
and level control bypass.
Quiet, ballbearing-loaded, variable-speed fans ensure efficient cooling. Removable
front panel dust filters simplify maintenance. Front panel-mounted carrying
handles can be easily detached when installed in door-equipped racks. Optional
output transformers are available for high impedance applications.
The TOA IP Series Amplifiers are backed with a five year warranty.
