1
Ethernet LAN Connection -
Plug The
Director into a 10BaseT network here. The in
-
ternal web server allows remote control of all
channels, signal processing and source selec
-
tion. See the section on Internet Connectivity
and Control for detailed information.
2
Ethernet Triggered LED -
When this LED
is on, the unit is being “triggered” via the
Ethernet and the 12 volt mini jacks are active
and powered for turning on some components.
3
Bypass Switch and LED -
For diagnostics
only. This button disables all the Ethernet
control and forces all channels on. If there is
a problem with the home automation system
and you really need music, this is quite useful.
4
Ground Lift Switch -
Be safe, use this switch
instead of a “cheater” plug. The switch selects
the isolation between the audio ground and
the AC earth ground. In normal operation,
the switch should be in the Ground position.
If there is AC hum, try the other two settings.
For safety, the chassis is always connected to
earth ground regardless of the switch setting.
5
Bus Inputs 1 and 2 -
These inputs provide
two distribution busses for sending a common
signal to multiple zones. The bus input switch
on each amplifier zone, or the ethernet con
-
trol, selects which input is playing in that
specific zone. For Bus 1, the second pair of
jacks can be used to daisy chain to another
multi-zone amplifier.
6
Local Inputs -
Any standard line level au
-
dio signal may be connected to these inputs.
As the name implies, this source will be
available only in a particular zone and only
if switched to local via the ethernet control
or the zone switch.
7
Input Gain Control -
Use a screwdriver to
adjust this level control for the input sensi
-
tivity of the zone. In general, you want the
gains turned down, counterclockwise, and
the pre-amp level running stronger for best
signal to noise.
8
Source Select Switches -
The “Bus 1/Net”
setting allows the source to be selected via
ethernet commands and the browser inter
-
face or come from “Bus 1” in the absence
of a ethernet connection. If the switch is
in “Bus 2” or “Local”, the audio signal
will come from that source and can not be
changed by ethernet commands.
