INTRODUCTION TO AIB-2000
8 INTRODUCTION TO AIB-2000
8.1 About the AIB-2000
The AIB-2000 is a complementary input/output device compatible with most cinema power amplifiers.
It provides functionality to connect additional signal sources, like satellite receivers, DVD-players and cable
receivers and offers dedicated H/I, V/I and LCR outputs. AIB-2000 is compatible with AIB-2000
macroprotocol and is easily controlled with media server automation commands.
Please refer to the ‘Audio Processing Settings for SR-1000’ document for additional information on how to
interface the AIB-2000 with the GDC SR-1000 Media Server and Cinema Sound System.
8.2 Unpacking and Checking for Shipping Damage
Your AIB-2000 has been completely tested and inspected before leaving the factory. Carefully inspect the
shipping package before opening it and then immediately inspect your new product. If you find any
damage notify the shipping company immediately.
The packing box contains the following:
▪One AIB-2000.
▪One AC Mains Power Cord.
▪This User Manual.
8.3 Packing Material
Please retain the original packaging of the AIB-2000 for RMA shipments.
NOTE: The transport and protective packing has been selected from materials that are environmentally
friendly, which can normally be recycled.

AIB-2000 CONNECTIONS
9 AIB-2000 CONNECTIONS
9.1 Installation
The AIB-2000 is a 1U Rack device and most conveniently installed in the amplifier rack it connects to.
NOTE: Instead of connecting the AIB-2000 to the power grid directly, it is recommended to plug the
device’s mains connection to a UPS outlet.
9.2 AC Mains Supply
The AC Main connection is made via the IEC C13 connector.
The DC series amplifiers have an automatic power factor correction system - PFC - for a perfect mains
network interface. The PFC minimizes the reactive power reflected on the network and reduces the
harmonic distortion on voltage/current waveform: in this way the amplifier is seen as a resistive load from
the mains network. Furthermore, the system allows performance to be maintained even in case of varying
mains voltage.
9.3 Routing Diagram
Refer to Section 4 for the signal routing diagram of your AIB-2000.

including emergency messages.
▪GAIN knob controls the gain of the preamplifier.
▪+48V button switches the +48 V phantom power supply ON and OFF.
▪HPF 100Hz button switches the built-in microphone high-pass filter on and off.
▪MIC IN button switches microphone input ON and OFF.
SELECTOR
The SELECTOR section controls the source for 7.1. OUTPUT connectors on the back.
▪NON-SYNC button chooses the Non-Sync in.
▪7.1 ANALOG button chooses the input from 7.1. INPUT connectors on the back.
