Regulatory and Safety Notices
FCC Notice
Part 15 of the Federal Communication Commission Rules and Regulations has established Radio
Frequency (RF) emission limits to provide an interference free radio frequency spectrum. Many
electronic devices produce RF energy incidental to their intended purpose.
These rules place electronic equipment into two classes, A and B, depending on the intended use.
Class A devices are those that may be expected to be installed in a business or commercial environment.
Class B devices are those that may be expected to be installed in a home or residential environment. The
FCC requires devices in both classes to be labeled with the interference likelihood and additional
operating instructions. The rating label on the equipment will show which class the product is (A or B).
Class A product will not have an FCC logo. Class B equipment will have an FCC logo. The information
statements differ on the two classes.
Class A Equipment
This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference, in which case the user will be
required to correct the interference at personal expense.

Modifications
The FCC requires the user to be notified that any changes or modifications made to Avid hardware that
are not expressly approved by Avid Technology may void the user’s authority to operate the equipment.
Cables
Connections to Avid hardware must be made with shielded cables with metallic RFI/EMI connector
hoods in order to maintain compliance with FCC Rules and Regulations.
PRODUCTS WITH MULTIPLE POWER INPUTS:
WARNING: Each power input is intended to be connected to a separate branch circuit. Risk of high
leakage exists if multiple inputs are connected to a single source and protective earth is not present. A
QUALIFIED SERVICE PERSON shall verify that each socket-outlet from which the equipment is to be
powered provides a connection to the building protective earth. If any do not provide this connection,
the QUALIFIED SERVICE PERSON shall arrange for the installation of a PROTECTIVE EARTHING
CONDUCTOR from the separate protective earthing terminal to the protective earth wire in the building.
Canadian ICES-003
Class A Equipment
This Class A digital apparatus meets all requirements of the Canadian Interference-Causing Equipment
Regulations.
Cet appareil numérique de la classe A respecté toutes les exigences du Règlement sur le matériel
brouilleur du Canada.

LED Safety Notices
Avid hardware might contain LED or Laser devices for communication use. These devices are compliant
with the requirements for Class 1 LED and Laser Products and are safe in the intended use. In normal
operation the output of these laser devices does not exceed the exposure limit of the eye and cannot
cause harm.
Standard to which conformity is declared: (IEC 60825-1)
Optical connections are located on the rear panel and are typically labeled “Optical” or “SPDIF/ADAT.”
The exact location of optical connections is identified more clearly elsewhere in the documentation for
the Avid hardware device.

Rack-mount Requirements
The following rack-mount requirements are listed below:
• Elevated Operating Ambient — If installed in a closed or multi-unit rack assembly, the operating ambient
temperature of the rack environment might be greater than room ambient. Therefore, consider installing the
equipment in an environment compatible with the maximum ambient temperature (Tma) specified by the
manufacturer.
• Reduced Air Flow — Installation of the equipment in a rack should be such that the amount of air flow
required for safe operation of the equipment is not compromised. Do not block vents.
• Mechanical Loading — Mounting of the equipment in the rack should be such that a hazardous condition is
not achieved due to uneven mechanical loading.
• Circuit Overloading — Consideration should be given to the connection of the equipment to the supply
circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
• Reliable earthing — Reliable earthing of rack-mounted equipment should be maintained. Particular
attention should be given to supply connections other than direct connections to the branch circuit (for
example, use of power strips).

Euphonix ML530 Mic-Line Interface Operation Manual

Overview
The ML530 Mic-Line Interface is a 24-channel, digitally controlled analog preamplifier.
The ML530 is controlled by the SC253i Interface Pilot, which is controlled from the
System 5 console surface. The ML530 is packaged in a 2RU enclosure.
Features
The ML530 provides gain over a range of -12 to +72 dB in 0.5 dB increments for each
channel. The ML530 also features a high-pass filter, HiZ/LowZ switch, and phantom
power.
Front panel LEDs provide status information for all features so the operator can quickly
view the status of each input channel. Red front panel LEDs indicate signal clipping,
mute, impedance, and phantom power activation. Green LEDs indicate signal presence,
activation of the high-pass filter, and pad attenuator.
Redundant power is supported by purchasing an additional power module (Euphonix
part number: 964-06692-01).
Applications
Used in conjunction with the Euphonix AM713 analog to MADI converter, the ML530
provides multiple variable gain inputs for the System 5 or Max Air. Additional ML530s
can be added if more than 24 channels of variable gain inputs are desired.

Power Switch: The power switch, on the lower right, turns the unit on/off.
Status LEDs: Eight LEDs provide status information for each of the 24 channels:
•Clip: Signal clipping (red)
•Mute: Channel muted (red)
•HiZ: High impedance (red)
•48V: Phantom power (red)
•Sig: signal present (green)
•HPF: High-pass filter (green)
•Phase: Phase invert (green)
•Pad: 12 dB attenuation (green)

Since the ML530 is digitally controlled via software, the power switch is the only front
panel control.

Inputs (38-pin Elco): 24 inputs are provided on two 38-pin ELCO connectors. The lev-
el of all signals input at these ports can be boosted or attenuated. In standard configu-
ration, the input cable is configured by customer. Elco connectors and pins are
provided. See Elco 38 Input/Output Pinout on page 17.
Outputs (38-pin Elco): 24 outputs are provided on two 38-pin Elco connectors. The
supplied output cables fan out to two sets of 12 male XLRs for connection to the
AM713 Analog to MADI converter. See Elco 38 Input/Output Pinout on page 17.
Control (DB-15): Input for digital control signal from PC253i Digital Pilot. Signal for-
mat is Euphonix TCC bi-directional serial protocol. All switching and gain controls are
communicated via this connector.
AC Line In (IEC) and Fuse Tray: The power connector accepts standard IEC power
cords. 90–250 VAC 110, 220, or 240 VAC, 50/60 Hz can be applied at this connector.
