ML530 Guideiv

Chapter 1: Introduction to the ML530 1
Chapter 1: Introduction to the ML530
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 2U rack
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 chan-
nel. Red front panel LEDs indicate signal clipping, mute, im-
pedance, and phantom power activation. Green LEDs indicate
signal presence, activation of the high-pass filter, and pad at-
tenuator.
Redundant power is supported by purchasing an additional
power module.
Applications
Used in conjunction with the Pro Series 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.
System Requirements and
Compatibility
Avid can only assure compatibility and provide support for
hardware and software it has tested and approved.
For complete system requirements and a list of qualified
computers, operating systems, hard drives, and third-party
devices, visit www.avid.com/compatibility.

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 software controlled, the power switch is
the only front panel control.

Inputs (38-pin Elco) 24 inputs are provided on two 38-pin Elco
connectors. The level of all signals input at these ports can be
boosted or attenuated. In standard configuration, the input
cable is configured by the customer. Elco connectors and pins
are provided.
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.
Control (DB-15) Input for digital control signal from PC253i
Digital Pilot. Signal format is Euphonix TCC bi-directional se-
rial protocol. All switching and gain controls are communi-
cated 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.
