IMPORTANT SAFETY INSTRUCTIONS
The lighting flash with arrowhead symbol within an equilateral triangle, is intended to alert
the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure
that may be of sufficient magnitude to constitute a risk of electrical shock to persons.
The exclamation point within an equilateral triangle, is intended to alert the user to the
presence of important operating and maintenance (servicing) instructions in the literature
accompanying the product.
1) Read these instructions.
2) Keep these instructions.
3) Heed all warnings.
4) Follow all instructions.
5) Do not use this apparatus near water.
6) Clean only with a dry cloth.
7) Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
8) Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus
(including amplifiers) that produce heat.
9) Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has
two blades with one wider than the other. A grounding type plug has two blades and a third
grounding prong. The wider blade or the third prong are provided for your safety. If the provided
plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
10) Protect the power cord from being walked on or pinched particularly at plugs, convenience
receptacles, and the point where they exit from the apparatus.
11) Only use attachments/accessories specified by the manufacturer.
12) Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold
with the apparatus. When a cart is used, use caution when moving the cart/apparatus combi-
nation to avoid injury from tip-over.

13) Unplug this apparatus during lightning storms or when unused for long periods of time.
14) Refer all servicing to qualified service personnel. Servicing is required when the apparatus has
been damaged in any way, such as power-supply cord or plug is damaged, liquid has been
spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or
moisture, does not operate normally, or has been dropped.
15) WARNING – TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE
THIS APPARATUS TO RAIN OR MOISTURE.
16) Do not expose this equipment to dripping or splashing and ensure that no objects filled with
liquids, such as vases, are placed on the equipment.
17) To completely disconnect this equipment from the AC Mains, disconnect the power supply
cord plug from the AC receptacle.
18) The mains plug of the power supply cord shall remain readily operable.
19) This unit is provided with a power supply cord set suitable for 120V AC input only (for U.S.A.
and Canada). For other than U.S.A. and Canada, a qualified person must provide for use with
this unit, an appropriate, approved power supply cord set which is in compliance with the end
use country requirements and has a minimum cross-sectional area of 1.0mm2.
20) For units with more than one power cord:
Caution: This unit has more than one power supply cord. Disconnect two power supply
cords before servicing to avoid electrical shock.
Attention: Cet appareil comporte plus d’un cordon d’alimentation. Afin de prévenir les
chocs électriques, débrancher les deux cordons d’alimentation avant de faire le
dépannage.
21) Operator Accessible Fuse:
Caution: For continued protection against risk of fire, replace only with same type and
rating of fuse.
Attention: Pour ne pas compromettre la protection contre les risques d’incendie, remplacer
par un fusible de même type et de même caractéristiques nominales.

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)
Figure 2 Front Panel Channel Status LEDs
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.
