System placement

Installing the CU(s) in a rack

Rack requirements for the CU

• EIA standard compatible 19-inch rack

• 1U-size rack mounting

• Rack equipped with safety guardrails to support the CU and a

board on which the CU is to be placed

When installing the CU(s) in a rack, keep the temperature within the rack below 45°C (113°F). High temperature may damage the internal components, causing a malfunction. Leave a space of 10cm or more on each side (top, right and left, rear) between the CU and other devices or the rack.

Rack mounting angles are fixed to the CU using the following screws. When using screws other than those listed here, check the specifications.

• S TIGHT tapping screws with nominal diameter 4×6mm*

* Substitutable for M4×6mm machine screws

Unbalanced connection

Since induction noises tend to occur due to difference in electric potential of chassis:

• Keep the chassis between each device at the same electric

potential.

• Use the same power system.

• Connect to the GND (ground) terminal or chassis ground of each

device.

AC power cord connection

Be sure to connect the AC power cord into a properly grounded wall outlet. Improper grounding can cause electrical shock.

When cleaning the units

Do not use any solvents or chemicals such as benzine, thinner, alcohol or electrical contact cleaner and protector. Doing so may cause deformation, damage and malfunction of the units.

About Audio‑Technica LINK

The system adopts the unique format Audio-Technica LINK for power supply and signal transmission between the control unit(s) (ATUC-50CU), discussion unit(s) (ATUC-50DU), etc.

Audio-Technica LINK is compatible with the Ethernet standards and allows a simple construction for universal Cat5e or higher cable connections. (A shielded cable with conductor size of 24AWG or higher in diameter is recommended.) Transmission of high-speed signals with low-latency allows stable control and uncompressed audio signal transmission.

• Has a standalone mode that can be started by operating the front panel

• Equipped with GPO terminal that notifies external devices when an overcurrent (2.6 A) is detected in the power supplied from RJ-45 terminals

Features of ATUC‑M43H/58H

• Equipped with an LED ring that enables power supply via 3-pin balanced connector while offering both high sound quality and user flexibility

• Adopted mechanics between the microphone connector and the discussion unit (ATUC-50DU) reduce vibration

• Adopted a double layer pop filter (windscreen inside the microphone)

• Improves RF measures against external radio waves

NOTICE

• Power is supplied to external devices from the 5 V pin (22); however this pin has a maximum rating of +5 VDC at 100 mA. When you use this, select a circuit or current limit (resistance value) so that the rating is not exceeded.

• If this is used beyond its ratings, it may cause the product to malfunction, but even more so, it may cause fires or unforeseen accidents.
