One K8 distribution leg can be run a total length of 200 meters no matter how many devices are connected
along the way.

How much delay is in the K8 system?
K8 has a total through delay of 1/2 ms. Adding K8 output devices adds no delay to the signal path
because all K8 devices, except for distribution amplifiers, are passive.
If a single K8 If a single K8 If a single K8 If a single K8 device fails does the whole system go with it? device fails does the whole system go with it? device fails does the whole system go with it? device fails does the whole system go with it?
No. K8 devices are passive and a single failure will not destructively affect any other device on the system.

How do I control K8 devices?
The K8 system is a single cable solution for both audio and control. A K+H terminal protocol is available
for connecting a PC. The control system protocol is also openly published for use with Stardraw, AMX,
Crestron and other control systems.
Do K8 devices need to have addresses assigned to them?
Do K8 devices need to have addresses assigned to them? Do K8 devices need to have addresses assigned to them? Do K8 devices need to have addresses assigned to them?
No, it is not required to make address assignments to K8 devices. Because all 16 channels of audio are
present everywhere on the bus all the time it is not necessary to specify an audio destination address. At
the factory all devices are assigned an address based on their serial number for control and monitoring
purposes. This ensures that no address conflicts will happen on the control bus when first connecting the
system. Control addresses may be changed and text names may be assigned to K8 devices using the
control protocols.
Can K8 be used in a star topology? Can K8 be used in a star topology? Can K8 be used in a star topology? Can K8 be used in a star topology?
K8 can be implemented in either a daisy-chain, star or hybrid topologies. Star topologies are accomplished
using active K8 distribution amplifiers (available 2008) to drive each leg of the star.

K+H offers bridging interface boxes to map EtherSound channels onto the K8 distribution system.

EtherSound is best utilized when high audio channel counts are required and when interfacing between
K+H and other manufacturer’s EtherSound enabled gear. K8 can operate as a stand-alone technology in
smaller systems. In larger EtherSound systems, K8 operates as distribution branches off the core
EtherSound trunk where only 16 audio channels are adequate.
