8.5 AUDIO INPUT CONNECTOR WIRING

The Audio section includes parallel LINK, which
allows users to distribute an audio signal to multiple
units. Up to 30 different modules can be connected
in parallel on the same balanced line (with a source
output impedance of 600 ohm).
CH 1 Line Input (female, balanced XLR) is wired in
parallel to CH1 Line Parallel Out (male, balanced
XLR). To create your own audio cables, please use
the following wiring diagrams:

8.7 AMPLIFICATION AND PROTECTION CIRCUITRY

The KMR33 is powered by a 2-channel digital amplifier with 2 x 125W @4Ω output power per channel
(EIAJ test).
The KRM33's amplifier functions, including crossovers, equalization and phase response are
controlled by an on-board DSP processor.
KRM33's amplifier is equipped with several protection circuits to prevent damage. Two independent
audio limiters – Clip Limiter and Average Power Limiter – protect the internal circuitry against
overload. A Peak Current Shut Down protects the output stage. If tripped, Peak Current Shut Down
will reset after 2 seconds. A Temperature Protection Limiter also ensures the output stage stays
below a temperature of 85° C (approximate temperature of output power device).
