The Attero Tech Axiom bus is a proprietary analog extension
solution that leverages unshielded twisted pair cabling (CAT 5/6)
to transmit 2 balanced audio channels, RS-232 control and 24VDC
power for audio signal extension applications.

The Axiom bus is designed to support distances of up to 100m
(total run length). The Axiom bus also supports daisy chain
connectivity of up to 2 Axiom devices to provide flexible
modularity for various audio device connectivity in installed AV
systems.

3 – Device Installation

Figure 4 - Dimensional Drawing

3.1 ML1 – Mounting

A typical installation will involve mounting the wall plate
into a pre mounted wall box or mounting bracket. Before
installation, make sure the wall box where the ML1 is to
be installed is pre-wired with a suitable cable back to an
Axiom-enabled expander/injector.

Prior to ML1 installation, ensure the power sourcing
device (Axiom expander/injector) is powered off.

Attach and unshielded CAT-5/6 cable from the Axiom­enabled device to the Axiom port A of the ML1.

With the cable attached, carefully place the ML1 into the
wall box taking care to not trap the cabling. Once in
place, secure it with the screws provided. Once the unit
is secured in the wall box, fit the Decora plate and secure
it with the screws provided.

Now you may apply power to the Axiom-enabled
expander/injector, the unit will power up and the signal
presence LEDs should blink once quickly.

The ML1 comes in a single gang US Decora style form
factor and may be mounted in most US single old and
new work back boxes and mud-rings. Given the single
gang size, the ML1 may be mounted in larger gang
boxes with other single gang form factor products to
provide flexible AV system modularity where needed.

*Note: CAD drawings can be downloaded from the
Attero Tech website. Please contact Attero Tech for any
further product related information that is not
accessible on the website.

3.2 – Signal Metering LED Indications

Figure 7 - Signal Flow

The ML1 is equipped with two LED indicators below the rotary
encoders for each the ¼”/XLR Mic input and the 3.5mm line input.
The following chart indicates the available LED status
information:

3.4 - Device Configuration and Workflow Overview

The ML1 may be configured for single use, or daisy-chained with
one other Axiom device.

The default configuration is for single device use with Port B
disabled and XLR enabled.

Figure 5 – LED Signal Metering

LED State Status

Off No signal present

Green -60 dBFS to < -20 dBFS

Yellow/Amber -20 dBFS to < -3 dBFS

Red -3 dBFS to 0 dBFS

Note: The full scale output of the Axiom bus is optimized for
+20dBu levels, so 0dBFS in terms of metering refers to +20 dBu

3.3 – Controls

The ML1 controls the desired input gain simply using the
coinciding input knob (see Figure 4). Turning the knob clockwise
raises the level, while counter-clockwise lowers.

Figure 6 - Switch Label/Config Options

The CH1 Select switches allows the integrator to route either the
XLR or a sum of the XLR and 3.5mm inputs to the CH1 output of
Axiom Port A.

The CH2 Select allows the integrator to route either the 3.5mm
input or the Axiom Port CH1 (daisy chained Axiom device) to the
CH2 output of Axiom Port A.

Figure 10 - AXP2O Dimensional Drawings

4.3 – Mounting

A typical installation will involve mounting an Axiom wall plate
into a pre mounted single-gang or larger wall box, standard
drywall bracket or mud ring. Before starting, make sure the wall
box where the Axiom device is to be installed is pre-wired with a
suitable unshielded CAT5/6 cable back to the AXP2O break out
box.

With the AXP2O powered off, attach the CAT cable from the
Axiom port of the AXP2O to the RJ45 on the Axiom device.

Apply power by plugging in the 24V DC power supply to the DC
power input on the AXP2O. The power LED on the AXP2O should
illuminate green. Additionally, the Axiom wall plate should also
start up and become ready to operate.

With the cable attached, carefully place the Axiom wall plate into
the wall box taking care to not trap the cabling. Once fully in
place, secure it with the screws provided. Once the unit is secured
in the wall box, fit the Decora plate over the front of the unit and
secure it with the screws provided with it. It is recommended to
not over-tighten the screws that attach the included Decora wall
plate to prevent cracking it.

*Note: CAD drawings can be downloaded from the Attero Tech
website. Please contact Attero Tech for any further product
related information that is not accessible on the website.
