The Delay page allows users to independently set
the delays for the speaker system (Subwoofer and
Speaker Out). This delay is summed with the delays
from the Routing pages of Subwoofer and Speaker
Out. The COARSE and FINE controls allow users to
change the delay in larger and smaller steps.

Notes: The delay control does not affect the XLR
DSP out. Delay for this output line can only be
managed through the K-Framework dedicated
controls.

8.6 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:

The KMT21 is powered by a 2-channel digital amplifier with 2000 W output power per channel (EIAJ test).

The KMT21’s amplifier functions, including crossovers, equalization, phase response, and driver protection,
are controlled by an on-board DSP processor.

KMT series amplifiers are 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 with a tripping point at 35A. 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).
