Using Figure 1 as a reference, follow these steps to install the product.
Step 1
A cut out in the wall will need to be made prior to installation. The cutout needs to be large enough to securely fit an Old
Work Bracket such as the Carlon SC200RR (drywall mounting) or a Low Voltage bracket such as a Carlon SC200A (stud
mounting).
Step 2
Connect the Ethernet cable to the RJ45 on the back of the InBox or OutBox product. Insert the device carefully into the wall
bracket and secure with the four provided screws.
Step 3
Mount the Decora faceplate and secure with four screws.
2.3 – Audio Connections
The inputs to either the InBox X2 or the InBox R8 can be mono or stereo. Any combination of mono or stereo inputs can be
used. The outputs from the OutBox X2 and OutBox R8 can also be used in any combination of mono or stereo as well. The
InBox M3 can accept mono on any input. Stereo audio input is also supported but dependant on the input used (see section
2.3.3 for full description).
2.3.1 – InBox and OutBox X2
The InBox X2 uses a female connector. The connector is a dual type that accepts either an XLR male or TRS male connector.
The OutBox X2 connector accepts only a female XLR connector only. Cable connections for all three types of connectors are
shown below.
The InBox X2 also has two externally accessible switches. Each switch is pressed to latch the switch in and pressed again to
release it. The switch on the left enables or disables phantom power. Phantom power is enabled if the switch is in the “in”
position. Phantom power is disabled if the switch is in the “out” position. The right hand switch is mic/line gain. Mic level is
selected if the switch is in the “in” position and line level is selected if the switch is in the “out” position.
The InBox X2 also has a clipping LED for each input channel. The LED will show yellow when the signal is 6 dB below
clipping. The LED will show red if clipping occurs.
2.3.2 – InBox and OutBox R8
The InBox R8 and OutBox R8 both use standard RCA type audio connectors. Each connector is numbered. Use standard
RCA cables and connectors to connect to the external audio equipment.
2.3.3 – InBox M3
The InBox M3 has three different types of connectors. The first is the same dual type XLR/TRS combination as used in the
InBox X2. This input can only be used with mono sources. In addition, the InBox M3 also has a pair of standard RCA type
connectors and also a 3.5mm stereo jack input. Both the RCA inputs, and the stereo jack input can accept either two mono
inputs or a single stereo input. Use standard RCA or stereo jack cables and connectors to connect external audio equipment
to these inputs.
