RELIABILITY IS EVERYTHING
The Australian Monitor KMa750... Compact, Well Featured and Sonically Superior.
The KMa750 offers the build quality, reliability and superior sound quality that Australian Monitor has
become renowned for around the world. The KMa750 features six individual, matched, precision
mosfet amplifiers rated at 125 watts at four ohms, in a compact 2 ru chassis. This unit also features
microprocessor controlled cooling and status indication. Channels three and four can be bridged to
deliver 300 watts at 8 ohms. An inbuilt subwoofer filter (120Hz) is included for this bridged output.
This filter can conveniently be engaged via a rear panel switch when required.
The convenience continues with the addition of the KMT750 which converts the outputs of the KMa750
to 100V, 70V or isolated 8 ohm outputs. The KMT750 includes 6 x transformers and a high pass filter for
each output to alleviate transformer saturation at the speakers. Simply connect all six outputs of the KMa to
the inputs of the KMT and then feed your speakers from the KMT750.
This convenient package is ideal for any installation or hire situation which calls for multi channel amplifiers
with superior sonic qualities and that famous Australian Monitor reliability. Examples of such applications
include nightclubs, hotels, function rooms /conference centres and soundscapes/surround sound.
