Overview
Housed in a 1RU enclosure, this excellent design incorporates two inputs
and six outputs. All inputs and outputs consist of a balanced 3 pin XLR
and dual RCA sockets. Both input and output XLR’s can be switch select-
ed for either balanced microphone or balanced line levels.
Each input can be selected either on or off to any output via the front
panel DIP switches. Level controls are provided for both inputs and all
outputs. Individual LED VU meters are provided for each input. The ver-
satility of the design allows for both inputs to accept either microphone,
balanced line or auxiliary source signals to be fed to any output at either
microphone, balanced line or auxiliary level. This allows great flexibility
to the system designer. Ideal for routing common signals to six different
zones or outputs in large installations, or for recording applications such
as media press conferences and courtrooms. The system can also be pow-
ered from 24V DC in battery backup situations.

DIP Switch Setup
The DIP switches on the front panel are used to
route inputs 1 and 2 to all 6 outputs.
Figure 1 shows the DIP switches related to outputs
1 and 2.
In this example:
Switch 1 will route input 1 to output 1
Switch 2 will route input 2 to output 1
Switch 3 will route input 1 to output 2
Switch 4 will route input 2 to output 2
Any configuration can be used. ie inputs 1 and 2
can be routed to outputs 1 and 2 simultaneously.
Figure 2 shows the configuration for outputs 1 and
2 plus the DIP switch associated with these out-
puts.
This DIP switch allows each of the 6 outputs to be
configured as either balanced microphone or bal-
anced line level signal.
In this example DIP switch 1 will set output 2 to
either XLR balanced or RCA balanced line level.
DIP switch 4 will set output 2 to either XLR bal-
anced or RCA balanced line level.
Figure 3 shows the configuration for all the DIP
switches on the rear of the unit. Switches 2 and 3
have no connection.
Power
The unit can be powered from a 24V DC source for
use in battery backup installations. Connection is
via 2.1mm DC socket..
