Adder II System Overview
About the Adder II system
About the Adder II system
The Adder II is a high-performance link for transporting analog and digital audio, two and
four wire intercoms, and various data formats using lightweight fiber optic cable. As a
modular system, the Adder II is highly configurable and scalable for use as a point-to-point
signal transport.
The Adder II features include:
• Up to 64 bi-directional channels of audio
• Four intercom module slots providing up to eight intercom channels
• Data and GPI capabilities
• Remote audio gain control
• Phantom mic power
• Industry leading latency and signal-to-noise specifications
An Adder II system is constructed from single RU frames that interface to a common
backplane, allowing the system to be sized to various requirements. Analog and AES TX and
RX frames can be combined with Intercom and Data frames to create an audio system that
is perfectly suited to your particular application. Whether you need 32 x 32 analog or 32
analog to 16 AES signals in just one direction, with or without intercoms and data, Adder II
gives you maximum flexibility.
Analog modules come in rows of 16 while AES modules are in rows of 8 and 16. In this way,
an AES TX can interface to an analog RX, thus bypassing the need for expensive D-A and AD converters. With ultra-low latency, delay is never an issue.
Analog TX modules feature preamps that allow 0, 10, 20, 30, 40, and 50 dB of gain
adjustments plus 12/48V phantom power via a convenient faceplate controls and LED
display. The Adder II includes remote control of these functions. With an optical budget
exceeding 25 dB, the Adder II can operate across the theater or across town.
Operation can be on one or two fibers or two standard coaxial cables. It is dual-wavelength
and can be easily converted to WDM single-fiber operation. GPI's and data channels are on
DB-9 connectors with RS-232, RS-422, and RS-485 ports. A built-in signal analyzer features
an LED bar graph and signal generator with three different tone frequencies and three level
choices in both the analog and digital domains.
The Adder II ships pre-configured and requires minimal onsite configuration.

Adder II Components
Base Unit
Each end of an Adder system consists of at least two parts: One base frame with control unit
and one or more input/output (I/O) modules.
Base units are common to all Adder II’s no matter how large or small. This is the optical I/O
and the first building block of all systems. The base frame also has the on/off switch for the
system, the local gain controller, the data I/O’s, and to thetone generator/analyzer.
Input/Output Modules
Each Adder II can be configured with one to nine input/output modules depending upon
the frame size selected. All I/O modules are one RU high.

Fig. 1-2: Input and Output modules
The input /output modules, also referred to as “banks”, can be any of a range of input or
output modules including analog or digital audio and intercom.
• For analog signals, banks are 16 wide.
• For AES signals, banks are 8 wide (16 channels).
• Otherwise, the base is always bank 0.
The next row up is Bank 1, etc. as long as all signaling is analog. If intercom modules are
installed, this module would always be the top-most module.
Systems are delivered pre-configured and each frame will be a mirror image of the other, so
that if Bank 2 on one end is a TX module, then Bank 2 on the other end will be an RX

module. It is possible to do analog to digital conversion between frames, so one end can be
analog and the other end can be digital/AES.
Each Adder II can accommodate one or two 12 VDC power inputs @ 3 Amps via 4-pin XLR or
terminal strip. Grass Valley’s ADAP-AC-04 is an acceptable external DC power supply.
Depending on version, there may be a third 12-18VDC input for intercoms.
If you require re-configuration of your Adder II system, it should be returned to Grass Valley.
Call our support department (see
Materials Authorization) number.
When removing the Adder II from the shipping boxes, check everything over for any
damage, including missing optical caps, bent metal or pins, and case scratches. Be assured
that the utmost care was taken in building and packing your Adder II, so report any damage
to the carrier and to Grass Valley.

Laser Safety
Laser Safety
WAR NIN G: Class 1 Laser. Do not stare into a connector port or fiber.
Laser Radiation
The unit is a CDRH Class 1 laser device. Although this means it is Eye Safe, you must avoid
looking directly at, or staring into, the laser beam located on an ST connector or on the end
of a fiber.
Infrared radiation is produced at the fiber connection port on the front of the unit and at
the end of unterminated optical fibers that are attached to this port. Avoid any direct
exposure to the light that comes from these sources.
Do not enable the laser when there is no fiber attached to the fiber connection port.
Do not attempt any type of service to this instrument other than what is instructed in this
manual. Refer any servicing needs to Grass Valley, a Belden Brand (see
page 37).

Power Requirements
Adder II Systems are largely “Plug and Play”, but there are several steps that must be
followed to ensure the reliability of your system. Providing reliable DC power and having
properly installed fiber optic cables are critical in maintaining reliable operation.
Any power supply used with your Adder II must provide a minimum of 3 amperes,
continuous, at 12 to 18 VDC. Power input is either through two 4-pin XLR-M connectors or
two terminal strips located on the left side of the rear panel that provide for full power
redundancy; see the table below for pinout and
outlets are within reach of their six-foot power cords.

Grass Valley’s ADAP-AC-04 meets the power requirements for Adder II, but any other
suitable DC supply may be used. Note that a fully loaded 125 Mb/sec system (64 bidirectional channels) can draw up to 5 Amps.
Once power is applied to the rear panel, the front-right mounted switch on the Base unit is
used to “power-on” the system.
• A Green LED near the input XLR’s indicates the presence of DC power.
• ARed LED next to the power switch on the front panel indicates that DC is present.
• A Green LED indicates that power is On.
Frames equipped with an 882i intercom bank will require it’s own 12-18 VDC power
connection to the INTERCOM POWER INPUT 30VDC above the MAIN input. The same wiring
conventions apply.
