IR and Power Connections
The K2 keypad can be connected
using either CAT-5 or shielded 4-
conductor, 22-gauge 2-twisted-pair
cable. The maximum recommended
cable length is 250 feet for either
type of cable. See page 15 for the
wiring color codes for both cables.
• When using shielded 22/4 cable,
use one twisted pair for power
and ground, and the other twist-
ed pair for status and IR signal.
Always leave the shield open at
the keypad end.
• When using CAT-5 cable, do not
connect the Orange/White and
Green/White to GND (ground) at
the K2 keypad.
Recommended Russound Cables
AW2260AB – shielded 4-conductor,
22 gauge 2-twisted-pair cable
AWCAT5 – 8-conductor, 24 gauge
CAT-5 cable
Speaker Connections
The amplifier and speaker terminals
connect to the K2’s internal relay for
muting a pair of speakers with the
Power key only. There is no speaker
volume control in the keypad.
