Russound CAV6.6 - Manual (Page 86)

86
Adding A-BUS allows sub-zoning of the audio dis-
tribution of the CAV6.6 system. This configura-
tion demonstrates sub-zoning of the first zone
through the use of an A-BUS expansion hub.
Only the first four (1-4) CAV6.6 zones can be
expanded using the same numbered (1-4) A-BUS
Ready Sub-Zone ports.
Powering the A-BUS Ready Sub-Zones
The four A-BUS Ready Sub-Zone ports must be
powered by a Russound A-PS 24VDC 2.5A
power supply, which is plugged into the 24VDC
2.5A POWER INPUT jack on the rear of the
CAV6.6. This is only required when amplified
control modules are used without an A-BUS hub.
A-BUS Hub
The A-BUS Hub is used with A-BUS amplified
control modules to create additional audio sub-
zones and listening options. Using an A-H2 Hub
connected to a CAV6.6 A-BUS Ready Sub-Zone
port provides two additional A-BUS Sub-Zones.
The A-H2 requires a 24VDC 2.5A Power Supply
such as the Russound A-PS power supply. Mount
the A-H2 near the CAV6.6 and source equipment
using screws or hook and loop fastener.
CAT-5 Connections
The A-H2 Hub connects to the CAV6.6 A-BUS
Ready Sub-Zone Port using RJ-45 CAT-5 cables.
The cable connects from the CAV6.6 Sub-Zone
port to the Expansion Input port on the Hub,
then from the Hub keypad output to the RJ-45
wall plate.
Keypad Connections
The A-BUS A-KP2 amplified keypad and the
A-VC2 amplified volume control connect to the
Hub via the wall plate. Use the CAT-5 T568A RJ-
45 wiring configuration for these connections.
Multi-Source Mode Switch
The Multi-Source Mode switch is located on the
side of the A-KP2 keypad. It can be set to multi
or single source. When the switch is set to
"multi," it allows the selection of sources 1
through 4 on the CAV6.6. If "single" is selected,
the A-KP2 will not allow source selection from
the keypad, but will allow selections by IR
remote.
Speakers
The speakers for the A-BUS Ready Sub-Zone are
connected to the individual A-BUS amplified con-
trol modules. The speaker wire is connected to
the keypad using the screw terminal on the rear
of the keypad.
